Diagnosis.
Face greyish white pruinose; ocellar tubercle with two pairs of proclinated black setae; mystical mystacal white, with a few black macrosetae dorsally; fore and mid femora sharply marked with black stripe on anterodorsal surface (
Fig. 14A
); hind femur wholly black (
Fig. 14C
); fore and mid tibiae wholly pale, except for a short discal black spot on anterior surface; hind tibia blackish or dark brown on outer fifth (
Fig. 14A
); hind femur with a cluster of 15 or more short, stout, sub-tuberculate, black and yellow macrosetae closely set and appressed (
Fig. 14C
); terminalia black (
Fig. 14D
); dorsal epandrial margin without an indentation, gently concave on its mid-length (
Fig. 15A–B, F
); apex of epandrium with a short projection pointed downwards (
Fig. 15A–B, F
); apex of gonocoxite almost sickle-like shape apically (
Fig. 15G–H
). This diagnosis is based on the original description of
Hull (1958)
and the description of the male terminalia provided in an addendum by
Sánchez & Camargo (2021)
.

Taxonomic discussion.
The
type
of this species was deposited in the Museu de Zoologia da Universidade de S„o Paulo (MZUSP) (
Papavero 2009
), however in two recent visits by the senior author to the collection (2015 and 2017), the
type
was not located and it is considered lost (see
Sánchez & Camargo 2021
).
Lamas (1973)
synonymized this species with
Ctenodontina maya
Carrera & d’Andretta, 1953
. Back in that time, only three species were known:
Ctenodontina carrerai
,
Ctenodontina maya
and
Ctenodontina pectinatipes
Enderlein, 1914
.
Lamas (1973)
described the fourth species,
Ctenodontina mochica
Lamas, 1973
, and as pointed out by
Sánchez & Camargo (2021)
, the discrepancy between
Ctenodontina pectinatipes
and
Ctenodontina mochica
, may have led
Lamas (1973)
to recognize
Ctenodontina carrerai
as a synonym of
Ctenodontina maya
, since they are much more similar when compared with
Ctenodontina mochica
and
Ctenodontina pectinatipes
.
Recently,
Sánchez & Camargo (2021)
revalidated the status of this species and described the male terminalia in an addendum to the original description, including new distribution records for
Peru
. This revalidation was based mainly on characters of the male terminalia. The femoral swelling in
Catostola carrerai
comb. rev.
, is shallower and almost inconspicuous (
Fig. 14C
); the dorsal epandrial margin lacks an indentation (gently concave) on its mid-length (
Fig. 15A–B, F
); the epandrial apex possesses a short projection pointed downwards (
Fig. 15A–B, F
) and the gonocoxal apex is sickle-like shaped (
Fig. 15G–H
). In the other hand
Catostola maya
comb. rev.
has a conspicuous femoral swelling (
Fig. 26
); the dorsal epandrial margin has an indentation on its mid-length (
Fig. 24E
); the epandrial apex is rounded and pointed posteriorly (
Fig. 24E
) and the gonocoxal apex is enlarged, spatulated and rounded (
Fig. 25E
).
Contrastingly,
Catostola carrerai
comb. rev.
, is more similar to
Catostola sagta
(
Vieira, Ayala-Landa & Rafael, 2017
)
comb. nov.
,
which also possesses an almost inconspicuous femoral swelling on the male hind femora (
Fig. 37
). The main differences are again in the male terminalia. In
Catostola sagta
comb. nov.
, the dorsal epandrial margin possesses a gentle indentation on its mid-length and a very conspicuous dorsal apical projection only slightly downwards curved apically, its proximal part much more enlarged (
Fig. 34E
) and the apex of the gonocoxite is pointed (
Fig. 35E
).
It is interesting to mention that in the description of
Catostola
stat. rev.
,
Hull (1958)
describes the S8 and in the description of the species, he calls the same structure as hypandrium. With the revalidation of
Catostola carrerai
comb. rev.
, by
Sánchez & Camargo (2021)
and with the current revalidation of the status of
Catostola
stat. rev.
, in the present work this species becomes a valid species of
Catostola
stat. rev.
Only additional specimens collected in
Peru
were available for our study through images, which were kindly sent to us by Pável Sánchez (MUSM). Thus, we decided to provide only a brief diagnosis for this species, since redescription based on images should be avoided because some important characters like pruinosity and chaetotaxy would not be properly seen or described.
