Integument preceding segment, exopod not unusually wide, with

Integument not rigid. Rostrum overreaching antennular
peduncle, armed dorsally and ventrally, without ventral blade or tongue-like
lobe extending ventrally from lateral carina. Carapace with dentate crest in
midline at base of rostrum, with marginal, unarticulated antennal and
pterygostomian teeth but without supraorbital tooth, depressed frontal or orbital
regions, or branchiostegal tooth or denticles. Abdomen with 1 st pleuron
entire, not bifurcate; 5th pleuron posteroventrally acute, not denticulate; 6th
somite without prominent spines, without articulated plate at posteroventral
angle and pleuron not curving around base of uropod. Telson tapering to sharp
posterior end, bearing 2 pairs of dorsolateral spines. Eye with eyestalk
movable, not concealed by carapace, cornea not noticeably narrower than stalk,
without ocellus. Antennule with stylocerite not in vertical plane, not bifid;
2nd segment without sharp, curved lateral tooth; 3rd segment without
dorsodistal

tooth or movable plate, dorsal flagellum slender, not
short or brush-like.

                 Antennal peduncle not overreaching antennular peduncle,
without 3 strong ventral spines; antennal scale overreaching antennular
peduncle, lateral tooth not near midlength, lateral margin not spinose.
Mandible without palp or incisor process. First maxilliped with caridean lobe
clearly discrete from exopodal lash, epipod bilobate. Second maxilliped with
terminal segment narrow and applied somewhat laterally to preceding segment,
exopod not unusually wide, with nonbilobate epipod and podobranch. Third
maxilliped with distal segment not flattened, with exopod, epipod, arthrobranch,
and reduced coxal exite. Pereopods without exopods, with terminally hooked
epipods on 4 anterior pairs, without arthrobranchs. First pereopod with fingers
shorter than palm, not terminating in distal spines, chela 1 xh times as
long as carpus, latter not excavated to receive propodus, ischium not produced
into unusually long saber-shaped process. Second pereopods symmetrical, fingers
no longer than palm, carpus subdivided into 12-22 articles. Third pereopod with
dactyl tapering gradually to acute apex, flexor margin armed with about 4
spines, dactyl and propodus not prehensile in functional males, propodus not
subdivided, carpus not conspicuously spinose. Uropod with lateral branch
bearing distolateral movable spine flanked laterally and mesially by sharp
tooth.

 

             Rostral
crest composed of 7-12 teeth, followed by 2-6 teeth on remaining dorsal margin
of rostrum; ventral margin armed with 7-16 teeth. Carapace not noticeably uneven
or coarsely pitted. Abdomen without any dorsal teeth. Telson without trace of
lateral teeth near tip. Maximum postorbital carapace length at least 15 mm.

Integument not rigid. Rostrum overreaching antennular
peduncle, armed dorsally and ventrally, without ventral blade or tongue-like
