Stenobermuda brucei

sp. nov.

Stenobermuda brucei   sp. nov.

(Žgure 22)

Type material. HOLOTYPE: ZMUC, 3.1 mm, sta CRU-1894, sand from reef, Bawe Island , Zanzibar, 25 m, 21 September 1995   . PARATYPES: ZMUC, one ovigerous  

2.5 mm, one 2.2 mm, same data as holotype.

Diagnosis. Cephalon with antennal tooth low, subacute, anterolateral tooth acute, surpassing antennal tooth; rostrum narrowly triangular, reaching beyond anterolateral tooth. Eye weakly pigmented, consisting of four ommatidia. Pleotelson length subequal to basal width, with single lateral tooth. Pereopod 1 male, ischium, merus, carpus and propodus having stout elongate setae on mesial surface near anterior margins; carpus having cluster of Žve stout fringed setae posterodistally; propodus subcircular, with three stout fringed setae on posterior margin, robust seta demarcating palm, latter having four slender fringed setae; dactylus having four fringed setae on cutting margin. Pereopod 2, carpus 3.5 times longer than wide, with two robust setae on posterior margin; propodus with two robust setae on posterior margin; dactylus biunguiculate, with small additional seta on posterior margin.

Remarks. Stenobermuda syzygus (Barnard, 1940)   , recorded from the southwest Indian Ocean at Still Bay, South Africa, is the only Stenobermuda   known from the Indian Ocean. This is a much larger species (6.5 mm) than the present species, and possesses a narrower propodus of pereopod 1 in the male. The two species recorded from Bermuda ( S. acutirostrata Schultz, 1979   , and S. ili   V ei Kensley, 1994) both possess much narrower propodi of pereopod 1 in the male, than is seen in S. brucei   .

Etymology. The species is named for Dr Niel Bruce of the National Institute of Water and Atmospheric Research, Wellington, New Zealand, who collected this species along with several others described here.
