Supplementary description

Male (holotype; Fig. 7 A–C)

Colour in alcohol: carapace, eye region, clypeus, chelicerae, chilum, sternum orange-brown; fangs brownish; endites, labium, venter opisthosoma straw coloured; leg and pedipalp segments straw coloured with brownish shades; scutum on dorsal opisthosoma brownish, with three pairs of irregular creamy blotches; lateral opisthosoma with dark striations. Fovea vertical, dark. Lateral eyes nearly contiguous. Cheliceral promargin with paired denticles. Chilum unipartite, inverted triangular. Sternum posteriorly bluntly pointed, with coxal and intercoxal extensions. Body length 6.51. Carapace length 3.69, width 2.76. Opisthosoma length 2.82, width 2.09. Eye diameters: ALE 0.13. AME 0.18. PLE 0.12. PME 0.10. Eye interdistances: ALE–AME 0.14. AME–AME 0.04. AME–PME 0.11. PME– PLE 0.32. PME–PME 0.11. Chelicerae length 1.06. Clypeus height at ALEs 0.57, at AMEs 0.72. Chilum length 0.16, width 0.32. Measurements of pedipalp and legs. Pedipalp 3.26 [1.14, 0.34, 0.25, 1.53], I 7.78 [2.11, 0.85, 1.87, 1.54, 1.41], II (right) 7.09 [1.95, 0.91, 1.54, 1.54, 1.15], III (right) 7.33 [1.96, 0.98, 1.48, 1.86, 1.05], IV 8.65 [2.65, 0.73, 2.31, 1.94, 1.02]. Leg formula: 4132. Pedipalp as in Fig. 8 A–G.

Female

Unknown.

Justfication of the transfer

Solanki et al. (2018) recently transferred S. gujaratensis to Suffasia based on one fresh male specimen collected in Gujarat. The examination of the type material of S. gujaratensis revealed that their transfer is wrong and this species in fact belongs to Laminion gen. nov. as it possesses a dorsal apophysis on patella, a huge prominent cymbial retrolateral flange, cymbial retro-basal processes, long, filiform embolus, lateral extensions of median apophysis and retrolateral processes of conductor ( Fig. 8B , D–G). Thus its transfer to Laminion gen. nov. is confirmed.

Remarks

The ZSI collection has one glass tube for this species, which is labeled as “ holotype ” (no register number) containing one male specimen in good condition. Its left pedipalp found removed and kept in the same tube.
