Periclimenes sibogae Holthuis, 1952

Periclimenes (Harpilius) sibogae Holthuis. 1952c:73, figs. 28. 29 [type locality: anchorage. Kepulauan Banda. Indonesia: 9–36 meters].

DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum not overreaching antennal scale, shallow, sinuously horizontal, rostral formula 1 + , posteriormost tooth isolated from remainder of dorsal rostral series, situated in line with or slightly posterior to level of hepatic spine; carapace without supraorbital or postorbital spine, hepatic spine smaller than antennal spine, arising posteroventral to latter, not extending beyond anterior margin of carapace, orbital angle shallowly rounded, not spatulate; abdomen with 6th somite only slightly longer than 5th; eye with comea hemispherical, not produced distally; antennular peduncle with 1 distolateral spine on basal segment; antennal scale about 6 times as long as wide, lateral margin deeply sulcate, distolateral tooth distinctly overreaching distal margin of blade; 4th thoracic stemite with short, stout median process; 1st pereopod overreaching antennal scale by length of chela and part of carpus, fingers spatulate, pectinate on opposable margins; 2nd pereopod with fingers as long as palm, carpus less than as long as palm, more than twice as long as distal width, armed with 3 distal spines, merus without distal tooth on flexor margin; 3rd pereopod with dactyl not subdistally truncate, without denticulate lobe on flexor margin, simple, not biunguiculate, flexor margin concave, propodus with spinules on flexor margin, not segmented; postorbital carapace length about 4 mm.

RANGE.—Known only from the unique holotype from Kepulauan Banda, Indonesia; 9–36 meters. (Dr. Holthuis has informed us that the specimens from the Sudanese Red Sea identified by him as P. sibogae and reported by Edwards and Emberton (1980:236) may not belong to this species.)

DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum not overreaching antennal scale, palaemonoid, nearly horizontal, rostral formula 1 + 8–9/2, 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 not noticeably larger than antennal spine, arising posteroventral to latter, not extending beyond anterior margin of carapace, orbital angle bluntly triangular, not ovate; abdomen without compressed dorsal prominence on 3rd somite, 6th somite more than 1 times as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, anterior pair arising at about mid-length; eye with cornea hemispherical, not produced distally; antennular peduncle with 1 distolateral spine on basal segment; antennal scale 2 times as long as wide, lateral margin nearly straight, distolateral tooth not reaching level of distal margin of blade; 4th thoracic sternite without slender median process; 1st pereopod over reaching antennal scale by about length of fingers, latter not pectinate on opposable margins; 2nd pereopods subequal, similar, fingers about as long as palm, carpus as long as palm, more than twice as long as distal width, without distal spines, merus without distal tooth on flexor margin; 3rd pereopod with dactyl not subdistally truncate, without denticulate lobe on flexor margin, biunguiculate, flexor margin concave, propodus with spinules on flexor margin, not segmented; 5th pereopod not overreaching antennal scale; uropod slightly overreaching extended telson; maximum postorbital carapace length 2.3 mm.

MATERIAL.—PHILIPPINES. Off Jolo Islands, Sulu Archipelago: sta 5141; 6°09′N, 120°58E; 53 m; coral sand; 15 Feb 1908 (0848–0905); 12′ Agassiz beam trawl, mud bag: 1 ovig female [1.3].—Near Siasi, Sulu Archipelago: sta 5147; 5°41′40″N, 120°47′10″E; 38 m; coral sand, shells; 16 Feb 1908 (1127–1147); 12′ Agassiz beam trawl, mud bag: 1 ovig female [2.1].—Off Tawitawi, Sulu Archipelago: sta 5151; 5°24′40″N, 120°27′15″E; 44 m; coarse sand, shells; 18 Feb 1908 (1307–1327); 12′Agassiz beam trawl, mud bag: 1 cephalothorax [2.0].

RANGE.—Known previously only from Hong Kong and Japan; associated with alcyonarians. The depths at which the species was taken by the Albatross (to 53 m) represent a considerable extension of the known bathymetric range.
