Integument articulated at posteroventral angle, pleuron not curving around

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
