Periclimenes pectiniferus.—Bruce, 1983d:209.

DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum somewhat palaemonid, not overreaching antennal scale, directed slightly anteroventrad, rostral formula 1–2 + 7/1, posteriormost tooth not isolated from remainder of dorsal rostral series, situated nearly in line with 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 triangular, not ovate; abdomen without compressed dorsal prominence on 3rd somite, 6th somite 1 times as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, anterior pair arising at mid-length; eye with cornea hemispherical, not ogival; antennular peduncle with 1 distolateral spine on basal segment; antennal scale about 3 times as long as wide, lateral margin slightly concave, distolateral tooth not quite reaching level of distal margin of blade; 4th thoracic sternite without slender median process; 1st pereopod overreaching antennal scale by slightly more than length of chela, fingers subspatulate, pectinate on greater part of opposable margins; 2nd pereopods slender, subequal, fingers as long as palm, carpus as long as palm, about 2 times 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 nearly straight, propodus with spinules on flexor margin, not segmented; uropod overreaching extended telson; postorbital carapace length about 3 mm.

RANGE.—Known only from a single specimen from east of Townsville, Queensland, Australia, in 30–35m, in addition to the two syntypes from Makassar Strait.

DIAGNOSIS.—Integument smooth, not pitted on lateral areas of carapace and abdomen; rostrum not overreaching antennal scale, narrowly palaemonid, directed slightly anteroventrad, rostral formula 0 + 5–7/1–2, posteriormost tooth not isolated from remainder of dorsal rostral series, situated slightly anterior to level of hepatic spine; carapace without supraorbital or postorbital spine, hepatic spine more robust than antennal spine, arising posteroventral to latter, not extending beyond anterior margin of carapace, orbital angle triangular, not ovate; abdomen without compressed dorsal prominence on 3rd somite, 6th somite 1 times as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, anterior pair arising slightly posterior to mid-length; eye with cornea hemispherical, not produced distally; antennular peduncle with at least 2 distolateral spines on basal segment, antennal scale about 2 times as long as wide, lateral margin nearly straight, distolateral tooth not nearly reaching level of distal margin of blade; 4th thoracic sternite without slender median process; 1st pereopod slightly overreaching antennal scale, fingers minutely crenulate on opposable margins; 2nd pereopods unequal, similar, fingers about as long as palm, carpus about as long as palm, about 1 times as long as wide, unarmed, merus with distal angle of flexor margin bluntly produced, not dentate; 3rd pereopod with dactyl very unequally biunguiculate and with 3 long, slender spines in same transverse line arising from distodorsal margin of corpus at base of unguis, flexor margin distinctly sinuous but without denticulate lobe, propodus with few small spines on distal of flexor margin, not segmented; uropod considerably overreaching extended telson; postorbital carapace length about 3 mm.

RANGE.—Philippines and Marshall Islands; associated with crinoids.
