CHATTERJEE, TAPAS, KOTOV, ALEXEY A., DAMME, KAY VAN, CHANDRASEKHAR, S. V. A. & PADHYE, SAMEER, 2013, An annotated checklist of the Cladocera (Crustacea: Branchiopoda) from India, Zootaxa 3667 (1), pp. 1-89 : 18

(29) Daphnia (Daphnia) obtusa Kurz, 1874 emend. Scourfield, 1942 s.lat.

Indian records. Jammu & Kashmir—Michael & Sharma B.K. (1988); Himachal Pradesh — Biswas (1964b); General record— Fernando & Kanduru (1984), Sharma B.K. & Michael (1987), Murugan et al. (1998), Raghunathan & Suresh Kumar (2003).

Remarks. Valid species described from Czech Republic ( Kurz 1874). Similar forms are very distributed worldwide and apparently are composed of a large group of species. Adamowicz et al. (2009) represented 12(!) obtusa -like species in their tree, but several species were missed ( Kotov & Taylor 2010).

Distribution. Almost cosmopolitan, recently introduced even in Australia ( Benzie 2005).

Daphnia (Ctenodaphnia) pamirensis Rylow, 1930

Indian records. Jammu & Kashmir— Brehm & Woltereck (1939); General record— Fernando & Kanduru (1984).

Remarks. Described from the Pamir (Rylow 1930). Junior synonym of D. fusca Gurney, 1907 ( Benzie 2005) .

Daphnia (Ctenodaphnia) projecta Hebert, 1977

Indian records. Tamil Nadu —Venkataraman & Krishnaswami (1984a), Venkataraman (1995a, 1999b), Raghunathan & Suresh Kumar (2002, 2009); General record— Murugan et al. (1998), Raghunathan & Suresh Kumar (2003).

Remarks. Species inquirenda. It was described from Australia ( Hebert 1977) with unsufficient level of morphological description. Then Colbourne et al. (2006) put this among the carinata -like taxa, but these genetical data were not coordinated with taxonomy. Benzie (2005) placed this taxon among junior synonyms of D. carinata King, 1853 . Even in case of future acceptance of D. projecta as a valid species, its presence in India needs special confirmation.

Daphnia psittacea Baird, 1850

Indian records. General record— Fernando & Kanduru (1984).

Remarks. It was described from United Kingdom ( Baird 1850). Species inquirenda.
