Indobathynella socrates n. sp. is described from Karaiguda Cave in the Visakhapatnam District of Andhra Pradesh state, south-eastern India. This is the first cavernicolous species of Indobathynella, which is incidentally the most reduced genus in the family Bathynellidae as a whole. The type species of this genus, Indobathynella prehensilis, is from a farm bore. The new species fulfils all the principal generic criteria of Indobathynella, but is distinctly different from I. prehensilis in several essential features: absence of subapical seta on antennary exopod; 4 claws on distal maxillulary endite; 6 teeth on mandibular gnathobase, and uropodal exopod without ventro-medial seta. These and all other salient differences between the two species are tabulated. Besides providing brief notes on conservation and biogeography of the new species, a key to all the known Indian taxa of Bathynellidae is given for the first time.

Magmatic History

SummaryThe alkali syenite assemblage of Kunavaram, Khammam district, Andhra Pradesh in south-eastern India, comprises perthite syenite and nepheline syenite. The massive perthite syenite (locally grading to alaskite) is fringed on either side by foliated nepheline syenite, the latter developing composite gneisses along the contact zones with the country rocks. The syenites are essentially hypersolvus although the alkali feldspar, the dominant constituent of the rocks, shows varying degrees of unmixing and Al/Si order. The mafic constituents (e.g. sodic pyroxene, amphibole and biotite) are appreciably rich in ferrous iron. Mineralogical and chemical data suggest that the primary crystallization characteristics of the syenites were not totally obliterated during the post-magmatic history of the pluton.
