Periclimenes rectirostris Bruce, 1981c:204. figs. 12–15 [type locality: southwest of Manila Bay, Luzon, Philippines; 13°53.1′N, 120°08.9′E—13°53.3′N. 120°10.7′E; 134–129 meters, probably associated with echinoid Eremopyga].
DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum overreaching antennal scale, shallow, tapering, horizontal, rostral formula 0 + 11–12/4–5, posteriormost tooth not isolated from remainder of dorsal rostral series, situated far anterior to level of hepatic spine; carapace without supraorbital or postorbital spine, hepatic spine stouter but not noticeably larger than antennal spine, arising slightly posterodorsal to latter, not extending beyond anterior margin of carapace, orbital angle subquadrate, not spatulate; abdomen without compressed dorsal prominence on 3rd somite, 6th somite fully 1 times as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, both pairs arising in posterior of length; eye with cornea hemispherical, not produced distally; antennular peduncle with 1 distolateral spine on basal segment; antennal scale about 5 times as long as wide, lateral margin nearly straight, distolateral tooth reaching level of distal margin of blade; 4th thoracic stemite without slender median process; 1st pereopod overreaching antennal scale by about length of chela, fingers subspatulate, pectinate on opposable margins; 2nd pereopod with fingers nearly as long as palm, carpus about as long as palm, about 2 times as long as distal width, without distal spines, merus with small distal tooth on flexor margin; 3rd pereopod with dactyl not subdistally truncate, without denticulate lobe on flexor margin, simple, not biunguiculate, flexor margin obscurely sinuously concave, propodus with spinules on flexor margin, not segmented; uropod overreaching extended telson; maximum postorbital carapace length nearly 6 mm.
RANGE.—Known only from the three type specimens from southwest of Manila Bay; 134–129 meters.
