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,
abrupt depressions on frontal or orbital regions, without subocular tooth

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

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

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
