Dicranodromia karubar Guinot, 1993

( Fig. 2 )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 27 (Timor Sea; 09°30.9′S, 127°56.6′E, 465–490 m depth), 3 m beam trawl; June 20, 1972; 1 ♀ (NSMT-Cr 29249: CB 13.2 mm, CL 18.5 mm including rostrum).

Remarks. A female at hand ( Fig. 2 ) agrees well with the original description by Guinot (1993) and also with the detailed redescription by Guinot (1995), having short stiff setae completely covering the carapace, chelipeds and ambulatory legs, but not always completely concealing the dorsal areolation and armature of the carapace. This coat of stiff setae ( Fig. 2 ) is the most important criterion distinguishing close relatives such as D. doederleini Ortmann, 1892 known from Japan, 65–275 m depth, and D. baffini ( Alcock and Anderson, 1899) , definitely known from India and the Bay of Bengal, 435–830 m depth.

Distribution. The known localities are off the Kai and Tanimbar Islands in the Banda Sea, Indonesia, 356–468 m depth. Davie (2002) listed this species as one of two Australian species of Dicranodromia based on the record of Tavares (1998) from off the Lacepede Archipelago, Western Australia, at 434 m depth.
