Strigivenifera bartschi
Kurshakov & Zolotuhin, 2013
Given the variation in external morphology as previously noted, a final pair of
Strigivenifera
with almost identical male genitalia described by
Kurshakov & Zolotuhin (2013)
is addressed here:
S. bartschi
Kurshakov & Zolotuhin, 2013
(TL:
Kenya
) and
S. tatooifera
Kurshakov & Zolotuhin, 2013
(TL:
DRC
; note the
holotype
locality on the distribution map of
S. tatooifera
is incorrect). When considering just the adult morphology of the illustrated
holotypes
, the difference between these two species is clear as
S. tatooifera
is considerably darker than the related species with more intensive colouration. However, as outlined previously, the absence of further illustrations of each species makes it difficult to understand the level of intraspecific variation, as was found in
S. albidiscalis
. The striking similarities in the male genitalia are as follows: the juxta processes are extremely long and thin, the valve is wide and gradually tapers, there is a complete lack of cornuti, and the distinct aedeagus possesses two moderately sclerotised projections at the distal end. This final characteristic is perhaps the most diagnostic, as in all other
Strigivenifera
species
the distal portion of the aedeagus is membranous and very weakly sclerotised. Unfortunately, the differential diagnoses provided by the authors lack details and only briefly compares the external morphology of
S. bartschi
with
S. albidiscalis
,
S. oris
,
S. neo
Kurshakov & Zolotuhin, 2013
and
S. tatooifera
, whilst
S. tatooifera
is compared only with
S. oris
and
S. neo
; it should be noted that neither
S. oris
nor
S. neo
occur in sympatry with
S. bartschi
or
S. tatooifera
. The comparison of the near-identical genital morphology of
S. bartschi
and
S. tatooifera
was surprisingly neglected by the authors.
The only noticeable difference between the male genitalia of
S. bartschi
and
S. tatooifera
is in the shape of the ventral edge of the valve: in
S. bartschi
, this edge is slightly more truncate whilst it is more rounded in the allied species. In order to investigate whether this was mere variation, two barcode-confirmed specimens from
Nord-Kivu
,
DRC
were dissected (BOLD process ids./gen. slide Nos.: ANLMN7890-21/TT 125; ANLMN7892-21/TT 124) and compared to
S. bartschi
from the type locality (BOLD process ids.: LIMBC814-11–LIMBC816-11; LIMBC818- 11). The results showed an intermediate valve shape between both species (
Figs. 12–13
,
25–26
), as also found in a
paratype
of
S. tatooifera
(
Figs. 11
,
24
), while every other feature of the entire male genitalia remained identical. Furthermore, the APWD between the
DRC
and Kenyan specimens was just 0.9%. From this, it is herein concluded that
S. bartschi
and
S. tatooifera
are synonymous and the latter is synonymised with the former:
