Taxonomic discussion.
This species can be differentiated from other
Catostola
species
mainly by the yellow legs with apical third of mid and hind femora dark brown (
Figs 16A–B
,
17C
) and the epandrium with a long, finger-like dorsal projection (
Fig. 17D–G
). The most similar species is
Catostola baleta
comb. nov.
that can be distinguished through epandrial finger-like projection which is constricted short before the mid-length of the epandrium with the projection slightly longer than half of epandrial length (
Fig. 17D–E
) and the S8 mid-posterior projection which is slightly constricted at the base (
Fig. 17G
).
Distribution (
Fig. 44
).
Honduras
(
Atlántida
). The original description was based on
one holotype
and
two paratypes
from the same locality as the
holotype
but collected on
May 2, 1923
(
James, 1953
). In this study, only the
holotype
was examined.According to Erika Tucker (
in litt
., 2019), curator at the University of Michigan Museum of Zoology (UMMZ), the
paratypes
were not located in the respective collection and its whereabouts are unknown.
Material examined.
