description: Laminion jatashankar (Talwar, Majagi, Bodkhe & Kamble, 2018) comb. nov.
Figs 15, 19
Euryeidon jatashankarae Talwar et al., 2018: 72, figs 5.1–7, 6.1–8 (♀) (remarks: in figures, partly named jatashankara (lapsus )).
Type material. Holotype ♀ from INDIA: Madhya Pradesh: Hoshangabad, Pachmarhi (not Panchmarhi) Wildlife Sanctuary, 22°31’30.00’’N 78°25’40.90’’E, September 2015; leg. S. Kamble; repository SRL JDPSM (no registration number), not examined. Three paratypes (male(s) or female(s) unspecified): one with same data as holotype; two from Maharashtra: Amravati, J. D. Patil Sangludkar Mahavidyalya College campus, 20°55’19.70’’N 77°18’45.70’’E, August 2015; collector unknown; repository SRL JDPSM (no registration number), not examined. (Talwar et al. (2018: figs 5.6, 6.3, 5, 7) presented the colour images of the habitus and genitalia, which are diagnostic and were used for comparative purposes).
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).
Description. For description of the female, see Talwar et al. (2018).
Male. Unknown.
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).
Distribution. India (Madhya Pradesh, Maharashtra) (Talwar et al. 2018) (Fig. 19).
