Abstract: We present a synopsis of the Trichocentrum-clade of Oncidiinae. In this revision, we recognize 85 taxa assigned to four
genera: Cohniella with 23 species in ive complexes and two natural hybrids; Lophiaris with 27 species and eight natural hybrids,
six of which are yet to be named; Trichocentrum with 27 species and two subspecies; and Lophiarella with three species. Cohniella
yuroraensis is referred to the synonymy of C. ultrajectina, C. allenii and C. christensoniana to the synonymy of C. nuda, and C. croatii
to C. lacera. Trichocentrum perezii is referred to the synonymy of Lophiaris andreana. A key to the genera of the Trichocentrum-clade
is presented as well as keys to the complexes or groups of species and, when applicable, natural hybrids of Cohniella, Lophiarella,
Lophiaris, and Trichocentrum.

The Trichocentrum Poeppig & Endlicher clade of
Oncidiinae, as circumscribed here, includes four genera:
Cohniella Pitzer, Lophiarella Szlachetko, Mytnik-Ejsmont
& Romowicz, Lophiaris Rainesque, and Trichocentrum
(Carnevali et al., 2013). Some authors recognize this clade
as a single genus using a broad deinition for Trichocentrum
(Williams et al., 2001; Sosa et al., 2001; Chase, 2009;
Neubig et al., 2012).
The taxa of Trichocentrum-clade are characterized by
one or rarely two leaves per sympodial module and a low
chromosome number (2n = 26–28) (Chase, 2009). They
are found from southern Florida (a single species) and
northern Mexico to southern Brazil and northern Argentina,
including the Greater Antilles (Pupulin and Carnevali,
2005; Carnevali et al., 2010; Cetzal-Ix and Carnevali, 2010;
Balam, 2011). Lophiarella is a genus with a more restricted
distribution being conined to southwestern Mexico and
northwestern Mesoamerica, hence Megamexico (Carnevali
et al., 2013). The taxa of these four genera grow in a variety
of tropical vegetation associations, ranging from lowlands
from tropical deciduous forests and tropical rainforests to
thorn scrub forests, but can also be found in pine-oak forests,
from sea level up to 1700 (–2800) m elevation. Overall, the
clade includes 85 taxa: 23 species in ive complexes and two
natural hybrids in Cohniella; 27 species and eight natural
hybrids (six of which are yet to be named) in Lophiaris;
27 species and two subspecies in Trichocentrum; and three
species in Lophiarella. The country with the highest species
diversity is Mexico with 29 taxa, 18 of which are members
of Lophiaris (10 endemic), seven belong in Cohniella (4
endemic), two (one endemic) in Lophiarella, and another
two (one endemic) in Trichocentrum. Mexico is followed
by Costa Rica (5 endemic), Colombia (4 endemic), Brazil (3
endemic), Venezuela (3 endemic) all with 14 taxa, Honduras
with 12 taxa, and Bolivia (one endemic), Guatemala, and
El Salvador all with 11 taxa. Other countries are represented
by fewer than 10 taxa (Table 1).
Characters used to recognize taxa and hybrids within
the genera are primarily loral, such as the size and color
(especially color patterns) of the lowers, shape and
ornamentation (including the calli) of the labellum, presence
or absence as well as the shape and ornamentation of the
lateral lobes, emargination at the apex of the central lobe of
the labellum, length of the spur (as in Trichocentrum sensu
stricto), column features (shape and size of the column base,
shape and position of the column wings), and the type of
indumentum of the anther (Pupulin, 1995; Cetzal-Ix and
Balam, 2012; Cetzal-Ix et al., 2013a–b). The vegetative
characters include the relative size of the pseudobulbs relative
to the leaves, the size, shape, thickness and transversal
section of the leaves, the length of the inlorescence relative
to the subtending leaf, and the position, number, and
arrangement of lowers in the inlorescence. Furthermore,
species or species complexes can be easily identiied using
these characters in combination with discrete patterns of
ecological and geographical distribution (Cetzal-Ix and
Balam, 2012; Cetzal-Ix et al., 2013a–b).
The aim of this contribution is to provide an updated list
of recognized species in the Trichocentrum-clade with their
taxonomic status, typiication, and geographical distribution
by country. A key to the genera of the Trichocentrum-clade
is presented as well as keys to the complexes or groups
of species, and natural hybrids of Cohniella, Lophiarella,
Lophiaris, and Trichocentrum. Furthemore, a table with
distribution of species by country, endemic species by
country, and iconography for some species are provided.

Cohniella allenii is no doubt referable to Cohniella
nuda. The latter is characterized by its minute column
wings, often almost absent. Furthermore, the morphology
of the small callus is unmistakable. It consists of three low
ridges lanking two depressions, which in vivo look not
only smooth, but moist, wet. The two external ridges are
close to, and parallel to the margins of the labellar disk. The
labellum is characterized by its long, narrow isthmus and
the relatively small lateral lobes, retrorse when lowers are
lattened. All these characters are observed in the type of
Cohniella allenii, the authors of which compared it to C.
cebolleta (as “C. ceboletta”), a species here referred to the
Cohniella ascendens complex. The “central lobe apically
retuse, not biid…” (Kolanowaska et al., 2016) is simply
a morphological variation (see igures in Dunsterville and
Garay, 1979: 670; Carnevali et al., 2010: 159, igure 1;
Cetza-Ix, 2012: 142, igure 3).
The type of C. christensoniana also agrees closely with
C. nuda (see diagnostic characters above and morphological
variation shown in Dunsterville and Garay, 1979: 670).
