Laminion katepagai ( Talwar, Majagi, Bodkhe & Kamble, 2018) comb. nov.

Figs 16 , 19

Euryeidon katepagai Talwar et al., 2018: 69 , figs 1.1–10, 2.1–6, 3.1–7, 4.8–11 (♁ ♀) (remarks: in figures, partly named katepagae (lapsus )).

Type material. Holotype (male or female unspecified) from INDIA: Karnataka: Kalaburagi (= Kalburgi), Chincholi Wildlife Sanctuary (formerly Konchavaram Forest ), 17°18’37’’N 77°52’23’’E, collector unknown, possibly Supriya Talwar ; August 2016; repository SRL JDPSM (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 ).

Description. For description of the male and female, see Talwar et al. (2018).

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 ).
