(52) Bosmina (Eubosmina) coregoni Baird, 1857 s.lat.

Indian records. Jammu & Kashmir— Yousuf et al. (1984), Nath (1994), Parveen (1988), Siraj et al. (2006, 2007), Rashid & Pandit (2008), Ahangar et al. (2012a); Rajasthan —Sharma R et al. (2011), Sharma V. et al. (2012); West Bengal — Mandal (1980); General record— Fernando & Kanduru (1984), Raghunathan & Suresh Kumar (2003).

Remarks. Indian records need to be checked. B. (E.) coregoni s. str. is apparently a valid species, described from the United Kingdom ( Baird 1857) first within the subgenus B. (Eubosmina) Seligo, 1900. This greatly polymorphic species is adequately studied genetically and morphologically in the northern Palaearctic and Nearctic only ( Haney and Taylor 2003; Kotov et al. 2009; Faustova et al. 2011). Normally, coregoni -like females in South Asian populations lack a serration on the mucro, which is the most important character for a discrimination between the subgenera B. (Eubosmina) Seligo, 1900 and B. (Liederobosmina) Bretek, 1997. Males, which are most valuable for taxonomy (see Kotov et al. 2009), were never described from South Asia. Therefore, we are not fully sure even of the subgeneric determination of South Asian " coregoni -like" populations.

Distribution. B. (E) coregoni s. str. is predominantly distributed in the northern Palaearctic. The South Asian fauna of B. (Eubosmina) and B. (Liederobosmina) needs to be revised completely.

Bosmina (Bosmina) cornuta ( Jurine, 1820)

Indian records. Jammu & Kashmir— Akthar (1972), Nath (1994).

Remarks. B. cornuta was described from Switzerland ( Jurine 1820). It is a junior synonym of B. longirostris (Kotov et al. 2009) , which was also described from Europe. But " B. cornuta " from India, described by Nath (1994) most probably was the later described B. tripurae , see below.

Bosmina (Sinobosmina) japonica Poppe & Richard, 1890

Indian records. Tamil Nadu — Kořínek (1971).

Remarks. B. japonica was described from Japan ( Poppe & Richard 1890). Material in Richard’s collection was recently re-studied by Kotov & Ferrari (2010), which concluded that this taxon is a junior synonym of B. longirostris (O.F. Müller, 1776) . The Indian “ B. japonica ” in Kořínek (1971) is actually the later described B. (B.) tripurae Kořínek, Saha & Bhattacharya, 1999 , see below.
