Periclimenes dentidactylus Bruce, 1984 FIGURE 22 Periclimenes dentidactylus Bruce, 1984a:7, figs. 1-6 [type locality: Makassar Strait southwest of Tandjung Mangkalihat, Borneo; 0°31.4'N, 117°5O.1'E; 592-595 meters]. DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum overreaching antennal scale, slenderly palaemonoid, nearly horizontal, dorsally slightly concave, rostral formula 1 + 6/3, posteriormost tooth not isolated from remainder of dorsal rostral series, situated in line with or anterior to level of hepatic spine; carapace without supraorbital or postorbital spine, hepatic spine larger than antennal spine, arising posteroventral to latter, extending distinctly beyond anterior margin of carapace, orbital angle subacutely produced, not ovate; abdomen without compressed dorsal prominence on 3rd somite, 6th somite about 1 3 /5 times as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, anterior pair arising in anterior '/2 of length; eye with cornea hemispherical, not produced distally; antennular peduncle with 1 strong distolateral spine on basal segment; antennal scale about 3 times as long as wide, lateral margin straight, distolateral tooth overreaching blade; 4th thoracic stemite without slender median process; 1st pereopod overreaching antennal scale by length of chela, fingers not pectinate on opposable margins; 2nd pereopod with fingers '/2- 3 /4 as long as palm, carpus x h- 2 h as long as palm, about 1 '/3 times as long as distal width, without distal spines, merus without distal tooth on flexor margin; 3rd pereopod with dactyl subdistally truncate, with denticulate lobe on flexor margin, complexly biunguiculate, flexor margin nearly straight, propodus with few small spinules on flexor margin, not segmented; 5th pereopod overreaching antennal scale; uropod reaching to about level of end of extended telson; maximum postorbital carapace length 8 mm. MATERIAL.—PHILIPPINES. Iligan Bay, northern Mindanao: sta 5515; 8°34'48"N, 124°01'24"E; about 1280 m (no sounding); 8 Aug 1909 (1042-1110); 12' Tanner beam trawl: 1 ovig female [8.1]. RANGE.—Philippines and Indonesia; 592 to about 1280 m. REMARKS.—The Albatross specimen of P. dentidactylus belonged to an undescribed species when it was first examined. The illustrations prepared at that time are reproduced here, not so much to show differences between this ovigerous female and the male holotype as to emphasize the similarities between the type specimen and one of the opposite sex taken at possibly more than twice the depth and more than 1000 km to the north. 120.
