Phintella platnicki Sudhin, Sen & Caleb, 2023: 76, figs 16-23 (♂, examined).

Type material.

Holotype male from INDIA: Tamil Nadu: Salem, Yercaud (10°46′13.95″N, 78°12′6.37″E), 18.x.2019, J. Thilak coll. (NZC-ZSI-7352/18).

Material examined.

INDIA: Karnataka: Mookambika Wildlife Sanctuary, Kodachadri , 14♀♀ & 8♂♂, 13°51'25.51"N, 74°52'2.03"E, 1330 m elev., 01.xii.2022, P. P. Sudhin coll. (NZC-ZSI-8376/18) GoogleMaps . Kerala: Idukki, Kuttikkanam , 7♀♀ & 6♂♂, 9°33'38.44"N, 77°1'2.99"E, 1106 m elev., 24.i.2023, P. Girish Kumar coll. (NZC-ZSI-8377/18) GoogleMaps .

Diagnosis.

The female epigyne of P. platnicki Sudhin, Sen & Caleb, 2023, is most similar to that of Phintella nilgirica Prószyński, 1992, from which it can be easily distinguished by the broad, funnel-shaped copulatory openings (relatively small and round in P. nilgirica ) and parallel copulatory ducts (separated, sub-parallel in P. nilgirica ) (cf. Figs 6E, F View Figure 6 , 11C, D, G, H View Figure 11 with figs 61-62 in Prószyński (1992)). For the diagnosis of male, see Sudhin et al. (2023).

Distribution.

India: Type locality - Tamil Nadu. New records from Karnataka and Kerala (Fig. 14 View Figure 14 ).

Variation.

Both sexes of the species have been collected from new localities in south India. Darker and lighter forms have been found in the collections and the variation in the colour pattern of the female have also been illustrated in Figs 9A-H View Figure 9 , 10A-D View Figure 10 , 11A-H View Figure 11 .
