Uroptychus raymondi Baba, 2000 (Fig. 22)
Uroptychus raymondi Baba, 2000: 250–252, fig. 3 [type locality: off St. Helens, Tasmania, Australia].– Davie, 2002: 32.
Material examined. VICTORIA: NMV J21038, 1 male (7.8 mm), 65 km SE of Point Hicks, Bass Strait, 38°11.7’S, 149°48.7’E, 644–650 m, Engel highrise trawl, S01/85/40, 3 Feb 1985. TASMANIA: SAM C6086, 1 ovigerous female (13.7 mm), Cascade Plateau, 287 km E of Southeast Cape, 43°51’S, 150°22’E, FV Labrador, K. GowlettHolmes, 21 Feb 1990.
Diagnosis. Carapace excluding rostrum slightly broader than long; lateral margins convex, irregularly tuberculate, with strong midlateral spine; anterolateral spine stout; outer orbital angle triangular. Rostrum sharply triangular, about half length of remaining carapace. Carapace dorsum setose and sparsely tuberculate. Sternite 3 (at base of maxilliped 3) depressed, anterior margin deeply concave, with Ushaped median notch; outer lobes of emargination angular. Sternite 4 (at base of pereopod 1) with triangular anterolateral projection. Abdominal segments setose. Eyestalks not exceeding distal half of rostrum. Antennal basal antennal segment with lateral tooth; ultimate and penultimate segments with distal tubercle. Antennal scale extending beyond midlength of ultimate peduncle segment. Maxilliped 3 carpus with blunt distolateral tubercle; merus with 2 tubercles on flexor margin. Cheliped setose, not more than 5 times carapace length, carpus and merus distally dentate. Pereopods 2–4 similar, setose; merus irregular tuberculate or with low, widely spaced teeth on extensor margin; propodi with pair of movable spines on distal flexor margin; flexor margin of dactyli with sharp, slender distal spine, broad, blunt penultinate spine, and about 10 obliquely directed, movable spines.
Remarks. The single, strong midlateral spine on the margins of the carapace will distinguish U. raymondi from all other congeners known from Australian waters.
Distribution. Bass Strait and eastern Tasmania at 644– 650 m.
