Genus Hindupisidium Vinarski & Bespalaya View in CoL gen. nov.
Zoobank number: urn:lsid:zoobank.org:act:6569B137-B63E-43D8-8878-621B085A9CF7 .
Type species: Pisidium clarkeanum G. Nevill & H. Nevill, 1871 .
Diagnosis: The maximum shell length is 3.6 mm. Shell triangular, moderately convex; the beaks are prominent, relatively narrow and markedly shifted posteriorly. Only one (exhalant) siphon present. The inhalant water current enters via the pedal slit. The outer demibranch is completely reduced or represent a very small outer demibranch. Both states of this character were also observed in Afropisidium kenianum from South Africa ( Korniushin and Glaubrecht 2002). However, according to Clewing et al. (2022), this species is a member of the genus Euglesa (see below).
Reproductive biology: The members of this genus are characterized as synchronous brooders (embryos are developing within a distinct brood sac).
Etymology: The genus name is derived from Hindustan, the Persian name for India, where its type species is distributed.
Distribution: The genus includes at least three valid species ( Table 1 View Table 1 ), whose ranges cover India, Myanmar, Vietnam, and Nepal ( Fig. 3E View Figure 3 ).
Remark: Although P. pirothi represents the type species of Afropisidium , according to Clewing et al. (2022), all African species, including P. ethiopicum (Supporting Information, Fig. S2H View Figure 2 ), P. cf. kenianum , P. ovampicum , and P. cf. pirothi , cluster within the Euglesa clade, and none of these taxa is found within the Afropisidium clade. In this case, the name Afropisidium cannot be applied to the clade, containing Pisidium nevillianum ( Figs 5B View Figure 5 , 6B View Figure 6 , and 7B View Figure 7 ), Pisidium javanum (van Benthem Jutting, 1931) , and Pisidium clarkeanum (Nevill & Nevill, 1871) , and, thus, we erected here a new genus to include these species formely classified within Afropisidium .
