Type material

Holotype INDIA • ♀ (holotype of Marpissa gangasagarensis ); West Bengal, South 24 Parganas Dist., Gangasagar Island, near Kapilmuni Ashram ; 21.6375° N, 88.0755° E; 5 m a.s.l.; 1 Jan. 1996; S.C. Majumder leg.; NZC-ZSI-5569/18 .

Remarks

This species was described based on a single female collected from Gangasagar Island, near Kapilmuni Ashram, West Bengal. The original description is too short and the illustrations are sketchy, thus not allowing recognition of the species. However, examination of the holotype kept in the Zoological Survey of India, Kolkata, allowed clarification on the taxonomic status of this species. Detailed examination of the holotype revealed that it is identical to Phaeacius fimbriatus . The epigynal structure with large oval windows and a broad median septum; pear-shaped spermathecae placed close to each other along the posterior margin; anterior portion with sclerotized loops of copulatory ducts and lateral membranous pockets with wrinkled appearance unambiguously match with P. fimbriatus (cf. Fig. 8A–C with Wanless 1981: fig. 4d). Marpissa gangasagarensis is therefore treated as a junior synonym of P. fimbriatus .

Distribution

India (West Bengal, Kerala) ( Roy et al. 2016; present data), Nepal, Indonesia (Java) ( WSC 2025) ( Fig. 12 ).
