Taxonomy 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 induced Van Soest (2024: 34) to propose to consider them separate species, to be named Hemigellius calyx (Ridley & Dendy, 1886) andHemigellius indicus (Dendy, 1922).

Synonymy Assgnment to Hemigellius was inferred from Desqueyroux-Faúndez & Valentine's (2002: 885) synonymy of Gellius calyx to Hemigellius. So far there is no express publication of the combination Hemigellius calyx var. infica. [details]Taxonomy 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.

These differences combined with the distance in occurrence of the two taxa induced Van Soest (2024: 34) to propose to consider them separate species, to be named Hemigellius calyx (Ridley & Dendy, 1886) andHemigellius indicus (Dendy, 1922).
