Justification of the synonymy of

.
Detailed study of the
types
of
S. maitraiae
(
Figs 27–28
) revealed that this species has all diagnostic characteristics of
D. luridus
: the inverted pyriform epigynal plate with antero-laterally thickened rims and small, sclerotized, horizontally oriented primary spermathecae with large, hyaline, inflated balloon-like secondary spermathecae (compare
Figs 29–31
with
Tikader 1982
: figs 261–262 and
Caleb, Karthikeyani & Muthuchelian 2014
: fig. 1e–f). Based on these observations, we consider
S. maitraiae
a junior synonym of
D. luridus
.
FIGURES 22–26.
Scopodes tikaderi
Gajbe, 1987
(NZC-ZSI-5045-46/18). 22–24 left pedipalp of allotype male (22 ventral view, 23 retrolateral view, 24 enlarged view of retrolateral tibial apophysis); 25–26 genitalia of holotype female (25 epigyne, ventral view, 26 vulvae, dorsal view). Scale bars: 22–23, 0.5 mm; 24–26, 0.2 mm.
Remarks.
One of the seven specimens in the bottle labeled as ‘paratype’ (NZC-ZSI 5009/18) actually belongs to a different gnaphosid genus. We were unable to trace out the
allotype
males in the collection, which may either be lost or misplaced elsewhere in the collection. There seems to be inconsistency in
paratype
labeling: one label mentions ‘two females’, where as another label indicates ‘seven females’.
FIGURES 27–33.
Scopodes maitraia
e
Tikader & Gajbe, 1977
(NZC-ZSI-5008-9/18). 27 holotype female habitus, dorso-retrolateral view; 28 paratype female habitus, dorsal view. 29 epigyne of holotype female, ventral view; 30 vulvae of the same, dorsal view; 31 epigyne of paratype female, ventral view; 32–33 labels from type bottles. Scale bars: 27–28, 2 mm; 29–30, 0.2 mm; 31, 0.5 mm.
Justification of the synonymy of
S
.
samarae
.
Judging from the original genitalic illustrations of
S
.
samarae
(
Gawande & Bodkhe 2018
: figs 5–6), it is clear that this species has all diagnostic features of
D
.
luridus
as mentioned under the synonymy of
S
.
maitraiae
(compare
Gawande & Bodkhe 2018
: figs 5–6 with
Tikader 1982
: figs 261–262 and
Caleb, Karthikeyani & Muthuchelian 2014
: fig. 1e–f). The species
S
.
samarae
should thus be regarded as a junior synonym of
D
.
luridus
.
