Type material.
Holotype
(male or female unspecified) from
INDIA
:
Karnataka
:
Kalaburagi
(=
Kalburgi
),
Chincholi Wildlife Sanctuary
(formerly
Konchavaram Forest
),

(no registration number), not examined. Two
paratypes
(male(s) or female(s) unspecified), with same data as holotype except
July 2017
, not examined. (
Talwar
et al.
(2018
: figs 1.4, 6, 2.3, 5, 4.8–9, 11) presented the colour images of the habitus and genitalia, which are diagnostic and were used for comparative purposes).
Diagnosis.
Male of
L. katepagai
comb. nov.
is similar to the males of
Laminion gujaratense
(Tikader & Patel, 1975)
in the general appearance of palp, but can be distinguished from the latter species by RTA with retrolaterally oriented tip (vs. prolaterally oriented in
L. gujaratense
), wide embolic base (vs. narrow in
L. gujaratense
), first cymbial process with narrow apex (vs. broad in
L. gujaratense
), and beak-like retrolateral branch of median apophysis (vs. widely triangular in
L. gujaratense
) (compare
Figs 16A–B
with
Sankaran
et al.
2020
: figs 8D–F). Female is most similar to
L. jatashankar
comb. nov.
in the general appearance of the epigyne, but can be separated from the latter species by the convex anterior margin of median, sclerotized plate (vs. slightly concave in
L. jatashankar
comb. nov.
) (compare
Fig. 15A
with
Fig. 16C
).

Justification of the transfer.
Talwar
et al.
(2018)
described
E. katepagai
based on
four specimens
collected from
Karnataka
. This species is also misplaced in
Euryeidon
as it lacks the prolateral extension of cymbium and the transverse band that connects the spermathecae. It seems that the authors misinterpreted the shadow of the anterior epigynal margin as the transverse band connecting the spermathecae (
Talwar
et al.
2018
: fig. 2.6, herein
Figs 16C–D
). This species is a member of
Laminion
based on the following features: domed prosoma in lateral view, high clypeus, patella with a dorsal apophysis, cymbium with large retrolateral flange and processes, long, filiform embolus, and epigyne with median and lateral plates (compare
Talwar
et al.
2018
: figs 2.3, 4.8, 9, 11, herein
Figs 16A–C
with
Sankaran
et al.
2020
: figs 1E–F, 3D, 6B). Based on these observations, the transfer
E. katepagai
is fully justified.
Distribution.
India
(
Karnataka
) (
Talwar
et al.
2018
) (
Fig. 19
).
Remarks.
Previously,
Laminion
is known to occur in the Indian States of
Andhra Pradesh
,
Gujarat
,
Odisha
and
West Bengal
(
Sankaran
et al.
2020
). The transfer of the two Indian
Euryeidon
species
extended its distribution to
Karnataka
,
Madhya Pradesh
and
Maharashtra
, indicating a wide distribution range of this genus in
India
(
Fig. 19
).
