Diagnosis.
Females of
L. jatashankar
comb. nov.
are similar to the females of
Laminion birenifer
(
Gravely, 1921
)
, the
type
species of the genus in the general appearance of the epigyne, but can be separated from the latter species by smoothly constricted lateral margins of median, sclerotized plate of epigyne (vs. strongly constricted in
L. birenifer
), and slightly concave anterior margin of median, sclerotized plate (vs. anterior margin with a conical protrusion in
L. birenifer
) (compare
Fig. 15A
with
Sankaran
et al.
2020
: fig. 3D).

comb. nov.
, holotype of
Euryeidon jatashankarae
Talwar, Majagi, Bodkhe & Kamble, 2018
. A epigyne, ventral. B vulva, dorsal. Abbreviations: lSP, lateral sclerotized plate; mSP, median sclerotized plate. Figures without scale provided and are adapted from

Justification of the transfer.
Talwar
et al.
(2018)
described
E. jatashankarae
based on
four specimens
collected from
Madhya Pradesh
and
Maharashtra
. They erroneously placed this species under
Euryeidon
as it lacks the transverse band connecting the spermathecae, which is the main diagnostic feature of the female
Euryeidon
species
(
Dankittipakul & Jocqué 2004
: figs 16, 27, 29, 34, 40, 42). Instead, it fits with
Laminion
based on the following features: domed prosoma in lateral view, high clypeus and epigyne with median and lateral plates (compare
Talwar
et al.
2018
: figs 5.4, 6.3, 5, herein
Fig. 15A
with
Sankaran
et al.
2020
: figs 1E–F, 3D, 6B). Moreover, the internal genitalia of this species have similarities with that of
L. debasrae
(Biswas & Biswas, 1992)
(compare
Talwar
et al.
2018
: fig. 6.7, herein
Fig. 15B
with
Sankaran
et al.
2020
: fig. 6C). Based on these observations, the transfer of
E. jatashankarae
is fully justified.
Nomenclatural note.
Since the specific epithet is based on the name of a natural cave and a holistic place of Lord Shiva (jatashankar) located in the
type
locality (as it was considered a noun in apposition), it should therefore be amended as
jatashankar
instead and rather not as
jatashankarae
or
jatashankara
(
lapsus
) as mentioned in the original description (
Talwar
et al.
2018
).
