Almanac of Alberta Acari Part II Version 2.02 February 2012 draftIntroductionThis is the second volume in the ongoing Royal Alberta Museum acarine Almanac series. Part Iis devoted to the oribatid mites (species over 0.3 mm in length) used as bioindicators by theAlberta Biodiversity Motoring Institute (ABMI). This volume, Part II, is devoted to the rest of theAcari known from Alberta. Included are the rest of the Superorder Acariformes: the smallerOribatida (< 0.3 mm in length) and Astigmatina (Astigmata); members of the sarcoptiformsuborder Endeostigmata and the trombidiform suborders Sphaerolichida and Prostigmata.Finally, the members of the Superorder Parasitiformes (Orders Ixodida, Mesostigmata) are listed.In total in both Almanacs there are records for 920 species, although many are unidentifiedspecies or spp. Also to be found here is a Glossary of Acarological Terms and referencesappropriate to this section of the Almanac.The smaller oribatid mites in Part II are listed in a format similar to Part I, but abbreviated,and in phylogenetic sequence (see Krantz & Walter 2009) by supercohort through family, butalphabetically for genus and species under family. Keys will be added as they are developed.DOC distribution information is from the Diversity of Oribatida in Canada website. Theremainder of the Acari are presented in various summary formats, often simply as lists of specieswith collection data under a family, and when possible a paragraph about the ecology of the mitesand one with diagnostic features. Feather mites (Astigmatina, Analgoidea, Pterolichoidea) arelisted primarily as genera with host records, because the species identifications are part of anongoing study at the University of Alberta. Most other groups are identified to a species level,although these are often unspecified.Naming protocols of unidentified species follow those in Part I (i.e. sp. 1-x, A-Z followed bythe initials of the identifier; cf for questionable identifications; s.l. for probable speciescomplexes) and may include additional qualifiers such as ‘sp. nr.’ (species near) or ‘n. sp.’ (newspecies). If an identification is not credited to another or supported by a literature citation, thenthe identification is my own (DEW). Since I am trying to provide a list of all Albertan Acari, butI cannot be considered a specialist on all groups, the reader should use their own judgement if anidentification seems doubtful. Please feel free to request images or specimens if you are revisinga group (David.Walter@gov.ab.ca). Additionally, the reader should remember that taxonomicconcepts can vary among specialists and are subject to change.Version 2.1This version of Part II includes significant additions to the known acarine fauna of Albertaand several new keys including illustrated keys to the families and genera of Alberta ticks and tospecies of Dermacentor (Rocky Mountain Wood Tick, Winter Tick, American Dog tick) andHaemaphysalis.AcknowledgementsGiven the caveats above, and accepting responsibility for any errors, I would like to thank thefollowing for contributing specimens, identifications or records of Alberta mites. At theUniversity of Alberta, Professor Heather Proctor (HCP) provided the data on feather mites, watermites, and most of the terrestrial Parasitengonina identifications; Professors Felix Sperling(FAHS) and Bill Samuel and their student Winnie Lam provided much of the information on8

Almanac of Alberta Acari Part II Version 2.02 February 2012 draftticks; Associate Professor Maya Evenden and her student Boyd Mori provided mites associatedwith Mountain Pine Beetle (Dendroctonus ponderosae). At the University of Calgary, AssociateProfessor Mary Reid and her student Haydeé Peralta-Vázquez provided specimens of mitesassociated with the Pine Engraver (Ips pini). At the Canadian National Collection of Insects &Arachnids, Dr Evert Lindquist (EEL) provided identifications and records; Dr Frederic Beaulieugenerously shared his database, Dr Valerie Behan-Pelletier (VB-P) provided identifications andrecords; and Dr Ian Smith contributed records of water mites and cooperated with HCP onpreparing the final list. Dr Kevin Floate and Derrick K. Kanashiro (DKK) of Agriculture Canada,Lethbridge, provided records of mites associated with dung beetles and soil mites, respectively.Dr Zoë Lindo (ZL) provided soil mite identifications and specimens. Dr Matthias Buck of theRoyal Alberta Museum (RAM) provided collections of mites phoretic on Hymenoptera. Dr BruceHalliday at CSIRO, Black Mountain, provided helpful comments and corrections on earlier draftsas did Professor Barry OConnor and Dr Pavel Klimov at the University of Michigan on thesection on Astigmatina (Astigmata). Dr Ken Fry at Olds College is searching for records ofagriculturally important mites that will be added when they are ready. Finally, there are all ofthose who have submitted mites for identification to me at the RAM or UA and my acarologicalcolleagues around the world who I have pestered for papers or other resources over the last year.To one and all, thanks. This section of the Almanac would not have been possible without theirhelp.Key to Superorders & Orders of Mites in AlbertaAs time permits, I will write a series of keys to help readers identify the mites known fromAlberta. Unless noted in the title, these keys will only apply to those mites that I know occur inAlberta. This considerably simplifies both writing and using a key, but limits its application inother regions of the world.Identification of a mite usually requires having the correct stage (usually the adult, butsometimes the deutonymph or larva) and often the correct sex (usually the adult female, but insome taxa the male). Also, in the vast majority of cases, your mite will need to be cleared (i.e. theinternal tissues need to be dissolved so that only the cuticle remains) and mounted on amicroscope slide – and you will usually need a good compound microscope. See the Manual ofAcarology 3 rd Edition (Krantz & Walter, editors, 2009) for detailed instructions.Key to the superorders & orders of mites in Alberta (adults)1. Stigmatal openings above or behind the leg bases in mid-body region, usually associated witha papillate groove (peritreme), plastron-like band, or sieve plate (behind leg IV); leg coxaedistinct and usually movable, not insensibly fused to body; gnathosoma with ring-like band ofcuticle surrounding cheliceral bases and on which the free segments (usually 5, rarely 3 or 4)of the palps articulate; venter of gnathosoma (subcapitulum) with median groove usually withseveral rows of small teeth (denticles) or produced anteriorly into a hypostome with densefield of retrorse spines; ocelli usually absent (one pair present on dorsal scutum in some ticks)................................................................................................... Superorder Parasitiformes (2)- Stigmatal openings absent or on anterior of the body (between cheliceral bases or on anteriorplate), never above or behind the legs in mid-body region; short peritremes sometimes present9

Almanac of Alberta Acari Part II Version 2.02 February 2012 draftSuborder EndeostigmataOverview: Endeostigmatid mites are mostly tiny, soft-bodied, and poorly known. The group is awaste basket of taxa that do not fit in elsewhere in the Sarcoptiformes (and sometimeshave been included within the Prostigmata) and probably not a monophyletic taxon.Even the relationships among the families are not clear, so I have not arranged theAlberta mites into superfamilies.Alicorhagiidae Grandjean, 1939Overview: Species of Alicorhagia are cosmopolitan members of mesic to dry soils and feed onfungi and nematodes. Only females are known and populations in Colorado have beendemonstrated to reproduce by parthenogenesis. Silken webs are spun to protect the animalsduring moulting and on which to lay eggs. This family has been reported from near Breton,AB, (Berg & Pawluk 1984), from near Lethbridge, AB, (Osler et al. 2008), from RoughFescue Prairie in the Porcupine Hills near Stavely (Clapperton et al. 2002), and is commonin many soils around Edmonton.Alicorhagia cf usitata Theron, Meyer & Ryke, 1971 – Moose Pasture Research Site (DEW) 8km W Chipman, AB; Dinosaur Provincial Park (DEW); Breton; EdmontonAlycidae G.

(scolyti group) – ex Ips pini, CalgarySuperfamily PygmephoroideaOverview: Pygmephoroids are primarily fungivores and often have dimorphic adult females: afree-living morph and one that has legs I modified for clinging to the hairs of a largeranimal (phoretomorph). Insects, especially flies, beetles, and social hymenopterons, areoften the carriers of the phoretomorphs, but other more unusual arthropods include beachhoppers, aradid bugs, mygalomorph spiders, and red velvet mites. Species of Pygmephorusare associated with the nests of small mammals and are phoretic in the fur of their hosts.Several schemes for superfamily and family-level taxa are currently in use for thePygmephoroidea-Scutacaroidea. The Manual of Acarology 3 rd Edition (Krantz & Walter 2009)recognises both superfamilies and 4 families. More recently, Khaustov & Ermilov (2011) arguethat only a single clade is involved, that Siteroptidae is a junior synonym of Pygemphoridae, andthat an additional family, Neopygmephoridae should be recognised. The key below attempts tointegrate the two schemes using Cross (1965), Savulkina (1981), Camerik et al. (2006), and otherrecent studies for generic characters.Key to Pygmephoroidea (+Scutacaroidea) in or near Alberta based on adult females(modified from Khaustov & Ermilov 2011)1.

Almanac of Alberta Acari Part II Version 2.02 February 2012 draftIxodidae Dugès, 1834Overview: Most hard ticks require three hosts to complete development: the larva, nymph, andadult each attach to a host, engorge, and then drop off and must find a new host aftermoulting (nymph, adult) or a spot to lay eggs after mating (which may occur on the host).In contrast, Winter Tick colonize their host as a larva and remain on the host until thefemale drops off to lay her eggs.

Members of the Cervidae (deer, elk, moose, woodlandcaribou) are considered the primary hosts, with moose especially severely affected, butrecords exist for other wildlife. Larvae hatch from eggs in the soil in late summer andearly autumn and seek a host (sometimes wandering on people, but not attaching). Moosemay harbour large populations and suffer significant winter mortality (Samuel 2004,2007). The ticks may carry a tularaemia-like bacterium (Leo et al. 2010).Dermacentor andersoni (Stiles, 1908) – Rocky Mountain Wood Tick is a three-host tick:larvae and nymphs usually attach to rodents or rabbits; adults seek larger mammalsincluding people. Adult ticks are active in spring. Wood Ticks are known vectors ofRocky Mountain Spotted Fever, Tularemia, and Colorado Tick Fever and may causeparalysis in wildlife, livestock, and pets.Key to Species of Haemaphysalis in Alberta1.

Grouse andturkeys may be heavily infested.Haemaphysalis leporispalustris Packard, 1869 – the Rabbit Tick (also Grouse Tick) is athree-host tick. Larvae and nymphs feed on snowshoe hares, other small mammals, orsome birds such as Ruffed Grouse, White-throated Sparrow, Swainson’s Thrush(Morshed et al. 2005). Adults prefer rabbits or hares. Adult populations peak during thesummer. Rabbit Ticks rarely bite people, but are considered vectors of tularaemia amonglagomorphs.Key to Sexes of Ixodes in Alberta1.

Adult female- Scutum covers most of dorsum; pair of porose areas absent ...................................... Adult maleIxodes angustus Neumann, 1899 – the Rodent Tick is usually found in nests and burrows ofsmall mammals such as Deer Mice (Peromyscus maculatus) and Red-backed Voles(Clethrionomys gapperi) (Sorensen & Moses 1998, Lausen 2005). Although technically athree host tick, the association with nests restricts the ability of the tick to feed on avariety of hosts. Strickland Museum (2011) records extend across the lower 2/3rds ofAlberta.Ixodes kingi Bishop, 1911 – the Rotund Tick typically infests mice and ground squirrels, butwill attached to people, pets, and a diversity of other mammals (Salked et al. 2006). TheStrickland Museum (2011) has numerous records from Edmonton south in Alberta.Ixodes pacificus Cooley & Kohls, 1943 – the Western Black-legged Tick is a three host tickthat has been reported from migratory songbirds in Alberta (Morshed et al. 2005). In otherparts of North America larvae and nymphs of this tick prefer lizards, ground foragingbirds, and small mammals; adults will feed on dogs, deer, rabbits, and people.95

Almanac of Alberta Acari Part II Version 2.02 February 2012 draftIxodes scapularis Say, 1821 – the Black-legged Tick is a three host tick that has beenreported from migratory songbirds in Alberta (Morshed et al. 2005). In other parts ofNorth America, larvae and nymphs feed on small mammals and adults on larger animalssuch as white-tailed deer, horse, livestock, and people. It is an important vector ofbabesiosis, tularaemia, and numerous rickettsial diseases.Ixodes sculptus Neumann, 1904 – the Sculpted Tick typically infests ground squirrels [exRichardson’s Ground Squirrel (Urocitellus richardsonii), Franklin’s Ground Squirrel(Poliocitellus franklinii) (Hilton & Mahrt 1971)], but will attached to people, pets, and adiversity of other mammals (Salked et al. 2006). The Strickland Museum (2011) hasnumerous records from the southern third of Alberta.Ixodes spinipalpis Hadwen & Nuttall, 1916 – the Mouse Tick has been reported from a shrewand a bushy-tailed wood rat in Alberta (Shemanchuk & Kiceniuk 1970). These ticks tendto remain in nests and burrows and are potential vectors of disease.Rhipicephalus sanguineus Latreille, 1806 – the Brown Dog Tick has been recorded inAlberta, but probably does not survive out of doors (CNC record, FAHS). Dogs are thepreferred host for all stages and this tick rarely bites people.Argasidae CL Koch, 1844Overview: Soft ticks in the genus Carios spend relatively little time on hosts and most of theirtime in or around nests and burrows. They may feed on several hosts during development.Members of the genus Otobius, however, are single host ticks and attach and engorge aslarvae and nymphs (adults do not feed). The soft tick body is leathery and the scutumcharacteristic of hard ticks is absent (except as a remnant in larvae). In addition to thespecies recorded below, the Spinose Ear Tick Otobius megnini (Dugès, 1883) is knownfrom British Columbia and the northern United States and may be present in Alberta.Carios concanensis (Cooley & Kohls, 1941) – (previously in Ornithodoros) Wilkinson et al.(1980) report this tick from Prairie Falcon (Falco mexicanus) in Alberta, but a number ofother birds are known hosts in the USA. The tick can be found on the hosts or in cracksand crevices in rock ledges or caves near host nests and will feed on bats.Carios kelleyi (Cooley & Kohls, 1941) – The Bat Tick (previously in Ornithodoros) has beenreported from five species of bats (Eptesicus fuscus, Myotis lucifugus, Myotis ciliolabrum,Myotis evotis, and Myotis volans) in south eastern Alberta (Lausen 2005). It would beexpected in and around areas where bats rest.Otobius lagophilus Cooley & Kohls, 1940 – the Rabbit Spinose Ear Tick has been reportedfrom southern Alberta (Brown & Kohls 1950). This is a one host tick and rabbits andhares (jackrabbits) are the preferred hosts; but pikes, ground squirrels, and cats have alsobeen reported to be infested. Larvae and a single nymphal stage attach inside the ears oron other parts of the body and engorge. Adults have poorly developed mouthparts and donot feed; eggs are laid off the host.Otobius megnini (Dugès, 1883) – Spinose Ear Tick is a one-host tick that infests the ears ofcattle, horses, and sheep and is a known vector of Q-fever. Wildlife, dogs, and rarely96

Canestrini, 1891Overview: The Mesostigmata currently consists of three suborders of mostly predatory orparasitic mites (a few are fungivores or feed on pollen and nectar) and includes such wellknown pests as the poultry red mite and varroa. Of the three suborders currently recognised,only two are known to occur in Alberta and one of these, Sejida, is restricted to a single,apparently undescribed species.Suborder SejidaSuperfamily SejoideaSejidae Berlese, 1913Diagnostic characters: Dorsal shielding fragmented; av4, pv4 present on intercalary sclerite ontarsus IV; posterior with long, horn-like projections bearing long seta in Alberta species.Overview: Sejid mites are predators and most diverse in the tropics and in association with deadwood habitats. However, at least one species of Sejus is common in aspen litter in Alberta.About 46 species have been described in five genera.Sejus sp. 1 DEW – Moose Pasture Research Site (DEW) 8 km W Chipman, AB; MeanookSuborder TrigynaspidaCohort AntennophorinaSuperfamily AntennophoroideaAntennophoridae Berlese, 1892Diagnostic characters: Large brown mites with elongate legs I found on ants.Overview: Species of Antennophorus Haller, 1887, are kleptoparasites of ants.Antennophorus sp.– Cypress Hills associated with Formica ants (Lindquist 1979)Suborder MonogynaspidaCohort UropodinaSuperfamily Polyaspidoidea97

These setae are not addedontogenetically; therefore, homologies are based on position and subject to variousinterpretations. Each pair of setae may represent one of the 6 presumed prosomalsegments; however, Grandjean believed that the dorsal podosoma and their setae werelost in acariform mites, in which case the prodorsal setae would derive from onlycheliceral and pedipalpal segments. The designations are: rostral (ro), lamellar (le),bothridial (bo or ss), interlamellar (in), and a pair of exobothridial setae variouslydesignated exa/ exp, ex1/ ex2, xs/ xi, xa/ xp, or if only one seta is present, ex.

Ventrallythe positions of the prosomal segments can be identified by the insertions of theirappendages, but dorsally they are obscured. The opisthosoma is thought to comprise anadditional 12-13 segments (body segments VII-XVIII or XIX), but appears to besomewhat to much reduced in most mites, except possibly Opilioacarida. In earlyderivative Acariformes (e.g. many Endeostigmata), hysterosomal folds are thought torepresent segmentation and in the Grandjean system are designated (from the sejugalfurrow to the anus): C, D, E, F, H, PS AD, AN, PA. There is disagreement in the literatureover the origin of 'segments' C and D. Adherents of Grandjean consider them to beopisthosomatic (with C probably representing a fusion of the pregenital [body segmentVII] and genital [VIII] segments). Others believe that C and D are the dorsal regions ofthe last two prosomal segments that bear leggs III and IV (i.e. body segments V & VI).sejugal suture (or plane) - a division cutting the acariform mite idiosoma between legs II-III.sensillum (pl. sensilla) (also sensilla, sensillae; 'sensillus' is incorrect) - a sensory structure;sensilla is often used for the bothridial seta in Acariformes.sensillus – the bothridial sensillum, bo, ssserrate - with closely set teeth that resemble the cutting edge of a saw.seta (pl. setae, from L. = bristle) - cuticular process composed of a hollow shaft (sometimes filledwith a refractive material) produced from a membranous socket (the alveolus); the hairlike,spine-like, branched or variously expanded structures on the surfaces of the legs andbody. Most setae function as mechanoreceptors, but others (e.g. solenidia) arechemoreceptors or have unknown or ambiguous functions.setal - of or pertaining to a seta.setule - a small, seta-like cuticular process, typically on the pretarsal empodia or claws.sigilla - muscle insertions ('scars'), usually visible as depressed and / or striate regions ("scars")on plates, oval or irregular in shape and often in clusters.sigillotaxy - the use of cuticular muscle insertions as taxonomic characters (designation = sg).sigla - designations for setae.ς (sigma) - designation for solenidion the genu of acariform mites, (φ (phi) on the tibia; ω(omega) on the tarsus, theta (θ) on the femur).simple - unadorned; simple setae are needle-like and without hairs or pectins.sinuate - with a winding, snake-like, or wave-like form.slit sense organ - a lyrifissure; a stretch receptor.soil-encrusted - mites with an adherent layer of soil particles; probably a tactile camouflage.soil mite - any mite found in the soil-litter or decomposition subsystem.solenidion (pl. solenidia) - a hollow, optically inactive chemosensory seta on the limbs ofacariform mites appearing to have transverse rows of minute pores (actually pore canals)under light microscopy, (the transverse pattern is often not apparent in SEM); oftenbulbous or otherwise modified; sometimes associated with a compaon seta. Solenidia are135

[Back to Top]spatulate - (L. spatula = spoon) spatula-shaped; variously interpreted, but usually referring tosetae that are flattened and somewhat expanded distally.spermatophore - any structure that carries a packet of sperm, including complex stalks depositedon substrate by male acariform mites and flask-like structures carried on the chelicerae ofmale mesostigmatans.spinae adnatae - a pair of tooth-like projections on the anterior margin of the notogaster ofdamaeid oribatids.spine-like - a seta or other structure that resembles a thorn or spine; spiform.spiniform -with the form of a tapering, spine-like process, tubercle or seta.spinule - a small, spine-like cuticular process.sp. nr. - species near, used for uncertain species designations (e.g. Cosmolaelaps sp. nr. vacua(Michael)), implying that the specimen referred to may represent a new species (see aff.,nr., and cf.); a less nebulous use of this formation is 'n. sp. nr.', i.e. new species near, andindicates that the taxonomist is convinced that the specimen represents an undescribedspecies related to the attributed species.spur - a projection, usually tooth- or spine-like, from the body or limbs.ss – the bothridial seta; also bostage - a distinct developmental form, e.g. the egg, larval, nymphal and adult stages. Since miteinstars are usually morphologically distinct, they are also stages (and see stase). Someauthors, however, insist that instar should be apolysis to apolysis and stage ecdysis toecdysis. Since apolysis can be a discontinuous process and, in any case, is difficult todetermine, in practice the difference between a stage and an instar is abstract and ofimportance only if you have a contentious referee.stalked - raised up or otherwise produced on a stalk.stase - one of the successive, morphologically distinguishable forms exhibited by a mite duringdevelopment. A stase is equivalent to an instar in mites; but theoretically, if no setal orother morphological changes occur across a molt, then several instars may occur in onestase. Mostly used by Grandjean and his followers as a theoretical concept.stegasime - having the chelicerae protected dorsally by a rostral tectum (see astegasime), as inmost oribatid mites.stellate - star-like.stenarthric - a subcapitulum with a triangular mentum and oblique labiogenal sutures; probableprimitive condition in Acariformes.136
