Torquella rotundirostris ( Lang, 1970) n. comb

Typhlotanais rotundirostris: Lang (1970) (2) 23(4): 277, 279–286.

Diagnosis: Carapace 1.5 times as long as wide. Pereonite-2 about 1.4 times as long as pereonite-1; pereonite- 3 wider (1.3 times) than long, and pereonite-5 about as long as wide. Chela three times as long as wide. Antennule article-3 twice as long as article-2. Pereopod-1 basis 1.5 times as long as merus and carpus combined, merus with short setae (one rod seta), propodus with short and long setae on dorsal margin; pereopod-2 propodus with two setae (one simple seta reaching half of dactylus), merus with one spiniform seta, carpus with two spiniform setae and two short simple setae; pereopods 4 and 5 propodus distal seta reaches end of unguis; pereopods 4–6 with numerous spines around prickly tubercles; pereopod-6 propodus with three sub- equal setae distally; uropod endopod twice as long as basal article, uropod exopod reaches about half of endopod proximal article.

Distribution: Species known only from type locality: Southern-East Atlantic (30°14.09'S, 13°03'E) at 3073 m depth.

Remarks: T. elegans , T. galatheae and T. rotundirostris are the only three members of Torquella having two long dorso-distal setae on the propodus of the second and third pereopods. Of these three species only T. galatheae has a spiniform dorso-ventral seta on first pair of pereopod while two others species have regular seta there. The presence of four and two setae on the merus of pereopods 2 and 3 respectively in T. elegans allows its distinction from T. rotundirostris which has only one spiniform and one regular seta on each.
