THE FAMILIES CALLIANIDEIDAE AND THALASSINIDAE,<br />

WITH THE DESCRIPTION OF TWO NEW SUBFAMILIES ,<br />

ONE NEW GENUS AND TWO NEW SPECIES<br />

(DECAPODA, THALASSINIDEA)*<br />

Katsushi SAKAI<br />

ABSTRACT<br />

In the family Callianideidae, Thotnassinia, Crosniera, and Mictaxius defined as the Thomassiniinae,<br />

CaUianidea and Paracallianidea gen. nov. as the Callianideinae, Afjc/tefeo as the Michelelnae suborn, nov.,<br />

and Meticonaxius, and Marcusiaxius as the Meticonaxiinae subfam. nov. are included. Paracallianidea gen.<br />

nov, is separated from CaUianidea, and Meticonaxius torbeni sp. nov. from the west coast of Malay<br />

Peninsula, and Marcusiaxius soelae sp. nov, from the Coral Sea, eastern Australia are described. Bristly<br />

setal rows on the carapace, abdominal pleura, and pereopods 2-4 are firstly noticed in Thalassinidae not<br />

as plumose setal rows in Callianideidae,<br />

INTRODUCTION<br />

Thomassinia De Saint Laurent, 1979 was designated as the type of a new subfamily<br />

Thomassiniinae within the family Callianassjdae Dana, 1852 by De Saint Laurent, 1979.<br />

This new subfamily is characterized by the presence of the epipods on pereopods 1-4, and<br />

a long posterior whip on the scaphognathite of maxilla 2. Meticonaxius De Man, 1905<br />

was classified first by De Man (1925:53) as a member of the family Axiidae Huxley, 1879,<br />

and later it was transferred by him to the subfamily Callianideinae Kossmann, 1880 of the<br />

family Callianassidae, because there is no linea thalassinica, and pleopods 2-4 are alike;<br />

he was followed in this by Bouvier (1925:469)(Table 1).<br />

Recently, the rows of plumose setae (= setal rows) on the carapace, abdomen, and<br />

pereopods are used as good characters in the familiy Callianideidae by Kensley & Heard<br />

(1991:493), These authors recognized seven genera, CaUianidea, Crosniera Kensley &<br />

* This paper was partly given to the 1st European <strong>Crustacea</strong>n Conference in Paris on 1. Sept, 1992.

SAKAI: CALLIANIDEIDAE AND THALASSINIDAE 3<br />

Heard, l991,Mictaxius Kensley & Heard, 1991, Thomassinea, Michelea Kensley & Heard,<br />

199U Marcusiaxius Rodrigues & Carvalho, 1972 and Meticonaxius, which are divided into<br />

two ingroups (1): Callianidea-Crosniera-Mictaxius-Thomassinia and (2): Michelea-<br />

Marcusiaxius-Meticonaxius.<br />

In the present taxon, Thomassinea, Crosniera, and Mictaxius are included in the<br />

Thomassiniinae De Saint Laurent, 1979; Callianidea and Paracallianidea gen. nov. in the<br />

Callianideinae; Michelea in the Micheleinae subfam. nov.; Meticonaxius and Marcusiaxius<br />

in the Meticonaxiinae subfam. nov. The family Callianideidae has characters of two<br />

families, Callianassidae and Axiidae, however it is separated from them by the presence<br />

of plumose setal rows on the carapace, abdominal somites, and pereopods. The subfamily<br />

Thomassiniinae is closely related with Callianassidae in having a linea thalassinica. Three<br />

other subfamilies, Callianideinae, Micheleinae, and Meticonaxiinae are not provided with<br />

the linea thalassinica as in Axiidae. The subfamily Callianideinae is characteristic in that<br />

the anterolateral lobe on abdominal somite 1 is absent, the scaphocerite of antenna 2 is<br />

re<strong>du</strong>ced; pereopods 1 are strongly unequal, and the pleopodal respiratory filaments are<br />

branched, while the other subfamilies, Micheleinae and Meticonaxiinae, are different in<br />

that the anterolateral lobe on abdominal 1 is present, the scaphocerite of antenna 2 is<br />

large, and pereopods 1 are subequal. The subfamilies, Micheleinae and Meticonaxiinae,<br />

show more differences; in the Micheleinae the rostrum is small, the propo<strong>du</strong>s of<br />

pereopod 4 is normal in form, the simple pleopodal filaments are present, and the<br />

rostrum is small, while in the Meticonaxiinae the propodi of pereopods 3-4 are expanded,<br />

the pleopodal filaments are absent, and the rostrum is conspicuous (Fig. 1).<br />

On the other hand, the present examination reveals that the rows of setal pits are also<br />

found in Thalassina anomala (Herbst, 1804), namely on the carapace, abdominal somites,<br />

and propodi of pereopods 2-4 as in the Callianideidae, although the setae are not<br />

plumose as in the Callianideidae, but bristly. This character is not found in other families<br />

of the <strong>Thalassinidea</strong>, suggesting that the Thalassinidae Latreille, 1831 is similar to the<br />

Callianideidae on this point.<br />

Kensley and Heard (1991:493) used 21 characters for their phylogenetic analysis,<br />

however in the present examination the rostral form, the form of the coxa of pereopod<br />

4, the shape of the eye, and the status of the cervical groove are added to these 21<br />

characters for reassessing the present taxa.

6 NATURALISTS, TOKUSHIMA, NO. 4, 1992<br />

Remarks. The Thalassinidae appear to be more closely related to the Callianideidae than<br />

to other families in the <strong>Thalassinidea</strong> and share the following features: 1) In the<br />

Thalassinidae the scaphognathite of maxilla 2 has numerous posterior setae, while in the<br />

Callianideidae it has a single whip-like seta, or two setae as in Michelea lamellosa Kensley<br />

& Heard, 1991. 2) Epipods are present on pereopods 1-4. 3) The carapace, the<br />

abdominal somites and the propodi of pereopods 2-4 have 1-4 rows of setal pits. In<br />

Thalassinidae the setae are bristles, while in the Callianideidae they are plumose. 4) The<br />

locations of the setal pits are different in the Thalassinidae and Callianideidae. In the<br />

Thalas&inidae the anterolateral region of the carapace has a horizontal setal row above<br />

the linea thalassinica (Fig. 2A-C), and another vertical row on the anterolateral margin<br />

of the branchial region; abdominal somite 1 has a large setal pit below the lateral carina<br />

(Fig. 2A-B, D), and abdominal somites 2-6 have 1-3 vertical setal rows posteriorly; and<br />

the propodi of pereopods 2-4 have a setal row distally on the articulation with the dactyl.<br />

In the Callianideidae the anterolateral region of the carapace has 1-4 setal rows; one on<br />

the postorbital/postantennal region, 1-2 rows below the lateral carina, and one just<br />

anterior to the cervical groove; abdominal somite 1 has a horizontal setal row; abdominal<br />

somites 2-6 have 1-4 setal rows; and the propodi of pereopods 2-3, or 2-4 have 0-2 setal<br />

rows (Kensley & Heard, 1991:493). 5) The propo<strong>du</strong>s of pereopod 3, or propodi of<br />

pereopods 3-4 are broadened and flattened, 6) The surface of the thoracic sternum<br />

attached to pereopod 4 is concave in Thalassina (Fig. 2E) as in Mettconaxius and<br />

Marcusiaxius, while it is convex in Callianidea and Michelea, 7) The uropodal exopod has<br />

no transverse suture.<br />

However, the family Thalassinidae strongly differs from the Callianideidae in the<br />

following points; 1) The carapace has a second cervical groove (De Man, 1928:6) before<br />

the posterior margin. 2) The carapace has a dorsomedian protrusion posteriorly. 3)<br />

Abdominal somite 1 has an anterior dorsal edge with an articulating and locking device<br />

with the posterior margin of the carapace. 4) The gills consist partly of trichobranchs,<br />

and partly of broad plates. 5) Pereopods 1 and 2 are subchelate. 6) No appendix interna<br />

is present on the pleopods in males and females, but a vestigial is seen on pleopod 2 of<br />

males. 7) Tlie uropodal exopod and endopod are rod-like in shape.

10 NATURALISTS, TOKUSHIMA, NO. 4,1992<br />

Type subfamiliy. Callianideinae Kossmann, 1880.<br />

Included subfamilies. Callianideinae; Meticonaxiinae subfam. nov.; Thomassiniinae;<br />

Micheleinae subfam. nov.<br />

Remarks. The family Callianideidae is characterized that the scaphognathite of maxilla<br />

2 has a long posterior whip, and the epipods are present on pereopods 1-4 as in the<br />

Axiidae. It is closely related to the family Callianassidae in that the eyes are flattened<br />

distally, and touched each other on the mesial margins; the coxa of pereopod 4 is<br />

expanded; and abdominal somite 1 has no anterolateral lobe for the articulation with the<br />

posterior margin of the carapace; however, there is no linea thalassinica as in the Axiidae.<br />

The subfamily Micheleinae is similar to the Axiidae because the linea thalassinica is<br />

absent; and the scaphocerite of antenna 2 is well developed; however, there is no<br />

anterolateral lobe on the pleuron of abdominal somite 1 as in the Callianassidae. The<br />

Meticonaxiinae are also similar to the Axiidae in that the pleuron of abdominal somite<br />

1 has a anterolateral lobe for the articulating and lockcking device with the carapace; that<br />

the linea thalassinica is absent; and that the scaphocerite of antenna 2 is spiniform.<br />

However, the Metieonaxiidae are characteristic, because the propod of pereopod 4 is<br />

expanded.<br />

Callianideidae Kossmann, 1888:80.<br />

Subfamily Callianideinae Kossmann, 1880<br />

Definition. Rostrum re<strong>du</strong>ced. Linea thalassinica obsolete. Cervical groove shortly<br />

notched middorsally. Thoracic sternum convexly attached to pereopod 4. Pleuron on<br />

abdominal somite 1 lacking anterolateral lobe. Eyes flattened distally, touched one<br />

another on mesial margins. Scaphocerite of antenna 2 re<strong>du</strong>ced to small scale. Exopod<br />

of maxilliped 3 well developed. Pereopod 1 strikingly dissimilar; merus unarmed on<br />

ventral margin. Coxa of pereopod 4 expanded. Pleopodal respiratory filaments of 2-4<br />

segments.<br />

Type genus. Callianidea H. Milne Edwards, 1837.<br />

Genera included. Callianidea; Paracallianidea gen. nov.


SAKAI: CALLIANIDEIDAE AND THALASSINIDAE 11<br />

Remarks. The subfamily Callianideinae is closely related to Micheleinae in that the<br />

carapace is turned up on the posterolateral margin, exposing the expanded coxa of<br />

pereopods 4-5 laterally; the pleopodal respiratory filaments are present; the linea<br />

thalassinica is absent; and the exopod of maxilliped 3 is well developed. However, the<br />

Callianideinae differ from the Micheleinae in having the first pereopods strongly<br />

dissimilar, and the merus of pereopod 1 has no ridge on the ventral margin, the<br />

scaphocerite is re<strong>du</strong>ced, and the pleopodal respiratory filaments are branched, while in<br />

the Micheleinae the first pereopods are subequal, the merus has a ridge on the ventral<br />

margin, the scaphocerite is spiniform, and the pleopodal respiratory filaments are<br />

unbranched.<br />

There are two species, CalMnidea typa irom the Indo-Pacific region, and C laevicauda<br />

fi-om the Caribbean Sea. Kensley & Heard (1991:500) mentioned that C typa differs from<br />

C. laevicauda in lacking any sign of a linea thalassinica, and in having bifurcating<br />

pleopodal accessory respiratory filaments that are divided up to three times.<br />

In my opinion, the differences in pleopods 1-2, the appendix interna of the male<br />

pleopod 2, the pleopodal respiratory filaments, the linea thalassinica, and the spinulation<br />

of maxilliped 3 between C typa and C. laevicauda, are sufficient to divide Callianidea into<br />

two genera, Callianidea and Paracallianidea gen. nov.<br />

ischium with few tubercles on its ventral margin; the merus with 1-2 low tubercles on the<br />

ventral margin; the carpus narrow, about one third wider than long, its lateral surface<br />

provided with a transverse groove subventrally, and a few tubercles at the acute ventral<br />

angle. Palm less than three times as long as carpus on dorsal margin, ventral margin<br />

crenulate; fixed finger with four teeth on cutting edge. Dactyl strongly curved, cutting<br />

edge with two rounded teeth proximally, and apart from it one rounded tooth. In the<br />

female the larger cheliped has the ischium and merus unarmed on ventral margin. Palm<br />

twice length of carpus, fixed finger armed with six teeth in proximal half of cutting edge.<br />

Dactyl with four teeth in proximal half of cutting edge, distal tooth largest, and situated<br />

Remarks. The subfamily Thomassiniinae was first established as a member of<br />

Callianassidae by De Saint Laurent (1979:1396) as it possesses a complete or incomplete<br />

linea thalassinica. However, later it was transferred to the Callianideidae by Kensley and<br />

Heard (1991: 493). The Thomassiniinae are different from other subfamilies in having<br />

a linea thalassinica; it is included in the Callianideidae as it has setal rows on the<br />

carapace, abdomen, and pereopods.<br />

Etymology. The species is named for Torben Wolff, the 2toological Museum of<br />

Copenhagen, Denmark, respected marine zoologist.<br />

Remarks. The present species is the first Marcusiaxius record from the Pacific Ocean.<br />

He is different from both Marcusiaxius colpos Kensley & Heart, 1991 and M. lemoscastroi<br />

Rodrigues & Carvalho, 1972 from the Atlantic Ocean. M. speMe is more closely related<br />

to M. lemoscastroi than to M. colpos; in M. spekai maxilliped 3 is provided with a very<br />

short exopod; maxilliped 2 with a short exopod, while in M. lemoscastroi maxilliped 3<br />

lacks the exopod, and maxilliped 2 has a short exopod, and in M. colpos maxilliped 3 with<br />

the exopod overreaching distal meral margin, and maxilliped 2 with well-developed<br />

exopod. The other characteristics of three species in Marcusiaxius are tablated as follows.<br />
