Gelliu s calyx var. indica Dendy, 1922

Gelliu s calyx var. indica Dendy, 1922: 27 (no illustration).

The variety was described by Dendy from Saya de Malha in the Western Indian Ocean, 10.4883°S 61.4833°E, depth down to 914 m (wet holotype specimen BMNH 1921.11.7.13) is inferred to be a Hemigellius , because the typical variety G. calyx Ridley & Dendy (1886: 334 ; 1887: 43, pl. VIII fig. 6, pl. XIII figs. 2 and 9, from deep water in the Southwest Atlantic Ocean off the coast of Rio de la Plata, Argentina, 37.2833°S 53.8667°W, depth 1097 m, wet holotype specimen BMNH 1887.5.2.255) was reassigned as type species of the genus Calyxadocia De Laubenfels, 1936: 70 , which in turn was assigned subsequently to the synonymy of Hemigellius Burton, 1932 by Desqueyroux-Faúndez & Valentine (2002b: 885) as Hemigellius calyx . The typical variety differs substantially from the present variety, the latter having a shape less pronouncedly stalked, with oxeas smaller and thinner than in the typical variety (530 x 10 µm vs 500–700 x 22 µm) and sigmas larger than in the typical variety (37 vs 20 µm). These differences combined with the distance in occurrence of the two taxa induce me to propose to consider them separate species, to be named Hemigellius calyx ( Ridley & Dendy, 1886) and Hemigellius indicus ( Dendy, 1922) .
