Integument
not especially rigid. Rostrum overreaching antennular peduncle, armed dorsally
and ventrally, with strong ventral blade, not projecting between bases of
antennules, or series of strong ventral teeth, without tongue-like lobe
extending ventrally from lateral carina. Carapace without discrete dentate
crest in midline at base of rostrum, without longitudinal lateral carinae,
without appressed teeth on lateral surface, without supraorbital tooth,
without
abrupt depressions on frontal or orbital regions, without subocular tooth
posterodorsal to orbital angle, latter not large, with antennal tooth, latter
neither submarginal nor basally articulated, without hepatic tooth, with
branchiostegal tooth, branchiostegal margin not denticulate, with
pterygostomian tooth. Abdominal somites not dorsally carinate or
posteromesially dentate, 1st pleuron not bifurcate, 4th and 5th pleura pointed,
not denticulate, 6th somite not armed with 7 strong spines, with plate
articulated at posteroventral angle, pleuron not curving around base of uropod.
Telson not tapering to sharp point,
posterior margin subtruncate or slightly concave, posterolateral angles not
sharply produced. Eyestalk movable, not concealed by carapace, cornea with
ocellus. Antennule with

stylocerite
not lying in vertical plane, not bifid or semicircular; 2nd peduncular segment
without sharp, curved lateral tooth; 3rd segment without sharp dorsodistal
tooth or movable dorsodistal plate; dorsolateral flagellum proximally stout but
not unusually short or brush-like. Antennal peduncle sometimes overreaching
antennular peduncle, not armed with 3

strong
ventral spines; antennal scale overreaching antennular peduncle, without
lateral tooth near midlength or small movable lateral spines. Mandible with
both palp and incisor process. First maxilliped with caridean lobe quite
distinct from exopodal lash, epipod bilobate. Second maxilliped with terminal
segment elongate and applied somewhat laterally to preceding segment, exopod
not unusually wide, with somewhat bilobate epipod and with podobranch.

 Third
maxilliped with distal segment not flattened, with exopod, epipod, small arthrobranch,
and coxal exite. Pereopods without exopods, with epipods and arthrobranchs on
1st to 4th pairs, epipods with terminal hook. First pereopod with fingers
shorter than palm, not terminating in interlocking spines, chela 1 vli to
2’/3 times as long as carpus, carpus not deeply excavate for reception of chela.
Second pereopods symmetrical, fingers shorter than palm, carpus subdivided into
10-17 articles. Third pereopod with dactyl not gradually tapering to acute
apex, armed with teeth on flexor margin, dactyl and propodus not prehensile in functional
males, propodus not subdivided, carpus not conspicuously spinose. Uropod with
lateral margin of lateral branch terminating in small fixed tooth with larger
movable

spine
mesial to it.

 

Rostrum usually longer than carapace, curved upward.
Carapace with single orbital margin. Antennular peduncle without erect spine on
3rd segment. Antennal peduncle with basicerite lacking prominent distoventral
tooth. Second pereopod with movable finger smooth, not finely serrate, on
opposable margin, carpus composed of 9-13 articles. Fifth pereopod with 2
subdistal spines on merus. Fourth pleopod with appendix interna attached to
endopod over much of length. Maximum postorbital carapace length about 13 mm
(Chace,
1997).
