(60) Grimaldina brazzai Richard, 1892

Indian records. Assam —Sharma B.K. & Sharma S. (2008a, b); Madhya Pradesh — Rane (1984c); Rajasthan — Venkataraman (1990b); Tamil Nadu — Raghunathan & Suresh Kumar (2002, 2009); West Bengal — Venkataraman & Das (1993), Venkataraman (1998c), Venkataraman et al. (2000); General record— Fernando & Kanduru (1984); Raghunathan & Suresh Kumar (2003).

Remarks. Valid taxon described from Gabon, West Africa ( Richard 1892). It probably consists of a series of cryptic species (H. J. Dumont, pers. comm.). Venkataraman (1998) recorded this species from West Bengal and claim that it is the first report from India, later Venkataraman & Das (1993) again said they had found the first record, although Rane (1984c) already found this taxon before.

Distribution. At the time, regarded as circumtropical ( Smirnov 1992; Kotov & Ferrari 2010).

Guernella ceylonica Daday, 1898

Indian records. General record— Brehm (1953), Raghunathan & Suresh Kumar (2003).

Remarks. Described from Sri Lanka ( Daday 1898). Junior synonym of G. raphaelis Richard, 1892 ( Smirnov 1976, 1992), also listed as such in Michael & Sharma B.K. (1988). However, G. raphaelis is described from West Africa, and ceylonica is an available name for Oriental populations if these would indeed prove to belong to a separate species.

Guernella odiosa ( Gurney, 1916)

Indian records. General record— Raghunathan & Suresh Kumar (2003).

Remarks. Raghunathan and Kumar (2003) listed this combination as apparent mistake. In reality, this combination was never proposed by any other author in cladoceran taxonomy. Sometimes Macrothrix odiosa was placed to the genus Gurneyella Brehm, 1930 (see Biswas 1971), not Guernella Richard, 1892 . If Guernella is a valid taxon, which is indeed very different from Macrothrix ( Smirnov 1976, 1992), Gurneyella is an apparent junior synonym of Macrothrix ( Kotov et al. 2005) . See Macrothrix odiosa for further comments.
