Taxonomical account of the Indian Cyzicid Ozestheria annandalei (Daday, 1913) (Branchiopoda: Spinicaudata) from peninsular India.

The spinicaudatan family Cyzicidae represents a group of morphologically variable species whose taxonomy is still being updated (Schwentner et al. 2009, 2015, 2020; Rogers et al. 2017). There are 21 species of spinicaudatans currently reported from the Indian subcontinent out of which 4 species represent the Cyzicidae family (sensu Rogers Padhye, 2015; not considering the species from Eocyzicus genus which are now shifted to Eocyzicidae family sensu Schwentner et al. 2020). Ozestheria indica (Daday, 1913), one of the four species, has been re-described very recently (Padhye, 2020). Ozestheria indica and Ozestheria annandalei (Daday, 1913) are the two valid species currently known from peninsular India (Padhye, 2020; Rogers, 2020). Padhye et al., (2015) re-described the female of a Cyzicus sp. which was later confirmed as C. annandalei (Rogers Padhye, 2015).
