Remarks. Valid species described from Norway ( Sars 1862a). Many similar forms were described worldwide, and they need to be revised (Van Damme et al. 2010). Provisionally, we can regard Indian populations to belong to C. rectangula s.lat. —even from this checklist, it is clear that confusion exists in attributing names to different species related to C. rectangula in India, as authors recognize clearly different forms (using names from different continents such as anodonta , holdeni , bukobensis , etc. to identify them). After investigating material collected by S. Padhye, it is clear that more than one species related to C. rectangula occurs in India (K. Van Damme & S. Padhye, unpubl. data). These need to be described in detail and correct names need to be attributed—this Coronatella section is the most complex taxonomical mess in the Aloninae ( Van Damme & Dumont 2008a) . Tuberculated animals that belong to rectangula- like species, have been called “ anodonta ”, but also this name is not useful (see there?), as the character used here for assigning it (tubercles on the valves) is subject to variability and true A. anodonta is described from Neotropics (see above).

Distribution. C. rectangula s.str. is restricted to the Palaearctic ( Frey 1988a; Sinev 2001a; Van Damme & Dumont 2008a).In the Oriental region, the speciose C. rectangula- complex remains to be revised and is most likely to contain several species, of which the distribution is now completely unclear.

Coronatella rectangula richardi ( Stingelin, 1895)

Indian records. Andhra Pradesh — Chandrasekhar (1998b, 2004a, 2006, 2010); Maharashtra — Rane (2005b), Pawar & Pulle (2005), Jayabhaye & Madlapure (2006), Waghmare & Lokhande (2009); West Bengal —Sharma B.K. (1978), Michael & Sharma B.K. (1988), Chatterjee & Chandrasekhar (1999); General record—Sharma B.K. & Michael (1987), Raghunathan & Suresh Kumar (2003).

Remarks. It was described from Switzerland ( Stingelin 1895). Junior synonym of C. rectangula Sars, 1862 according to Sinev (2001a), status unclear according to Van Damme et al. (2010). In any cases, this is not valid taxon for India, where a lot of confusion exists in rectangula- related species.

Euryalona occidentalis Sars, 1901

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

Remarks. Dubious record. E. occidentalis was described from Brazil ( Sars 1901). Even if the E. orientalis - group would turn out to consist of a series of species with regional endemism, the chance to find this Neotropical taxon in India (very closely to type locality of E. orientalis s.str.) is low. Most likely, this is an erroneous identification.
