Torquella parangularis ( Kudinova-Pasternak 1975) n. comb.

( Fig. 43 )

Typhlotanais parangularis: Kudinova-Pasternak (1975) 103: 213, 216, 226; Kudinova-Pasternak & Pasternak (1981) 115: 122, 123; Kudinova-Pasternak (1985) 120: 55; Kudinova-Pasternak (1990) 126: 96; Larsen (2005): 210.

Material examined: Holotype: female, Mc 981, Akademik Kurchatov, Station 916, 56°29.4'S 50°51'W, depth 4664–5631m.

Diagnosis: Carapace 1.2 times as long as wide. Pereonite-2 1.6 times as long as pereonite-1; pereonite-3 longest, 1.25 times as long as wide. Chela three times as long as wide. Antennule article-3 twice as long as article-2. Pereopod-1 merus and carpus more than half as long as basis, merus with two short setae, propodus with three subdistal setae dorsally; pereopod-2 propodus with one seta reaching half of dactylus, merus with one short and one long seta (about half of carpus), carpus with three short simple setae dorso-distally; pereopod-4 and 5 propodus distal seta reaches end of dactylus; uropod exopod as long as endopod proximal article.

Distribution: Species known only from type locality: Scotia Sea at the depth range from 4664 to 5631 m.

Remarks: Torquella parangularis is distinguished from the other species of the genus by the short uropod exopod that is as long as the endopod proximal article. A relatively short uropod exopod occurs in T. eltaninae n. sp., but it has a much shorter antennule article-3 and one long distal seta on the pereopod-6 propodus.
