Carapace dorsal surface weakly convex, ovoid to weakly subhexagonal outline, wider than long (including anterolateral teeth), fronto-orbital width slightly exceeding 0.6 carapace width; front broadly convex with small median V-shaped notch separating shallow unimarginate lobes to each side, frontal margin of each lobe bearing slightly enlarged granules, lateral tooth of each frontal lobe obsolesent, lateral margin deflected to intersect antennal sinus; dorsal regions weakly defined, furrows of mesogastric, gastric, and anterior cardiac most evident; five anterolateral teeth, first tooth (outer orbital corner) subacutely angular, weakly separated from lobiform second by shallow depression of margin, third and fourth broadly lobiform to somewhat rounded or subrectangular, fifth small, subacutely angular. Third maxilliped merus distal margin sinuous, slightly produced to form small prominence near articulation with carpus. Cheliped merus superolateral margin with rough row of denticles, variably grouped to form serrate teeth, in major cheliped some forming sharp serrate teeth; carpus superior and lateral surfaces smooth to minutely granulate, microgranules forming weakly defined lines or surmounting weak elevations, supero-external surface marked by depression parallel to distal margin, internal margin with proximal angle weak, surmounted by line of low granules, distal angle stronger, forming blunt distally directed tooth. Major chela propodus mostly smooth to microgranulate, superior longitudinal crest weak, unarmed, adjacent external furrow shallow; dactylus opposable margin with slightly enlarged, lobiform basal tooth proximally. Ambulatory pereopods 2–5 relatively narrow, 2–4 subequal in size, merus length in all greater than 3 times greatest width, merus length approximating or slightly exceeding 1/2 carapace length; pereopod 5 smaller, propodus stouter than in other ambulatory pereopods, merus length not exceeding 1/2 length of carapace; merus in all ambulatory pereopods with superior margin unarmed, at most with dentiform granules variably concealed by plumose setae, inferior margin finely granulate; carpus superior margin with dense tract of short stout papilliform setae along crest; propodus superior margin with dense field of papilliform setae, dactylar-propodal locking mechanism not developed; dactylus stout proximally, inferior margin lacking subterminal prehensile tooth, superior margin densely covered by short papilliform setae, inferior margin with less dense slightly longer stiff simple setae. Male anterior thoracic sternum length (sternites 1–4) about 2/3 greatest width of fourth sternite (including episternites), eighth sternite exposed in subquadrate gap between lateral margin of flexed second pleonite and pereopod 5 coxa, exposure narrowly extending to anterior of condyle. Pleon of male with third through fifth pleonites fused, widest reach of first pleonite at its articulation with carapace, laterally rounded to articulation with second pleonite; telson subtriangularly rounded, widest in proximal one-third. Male first gonopod tip of highly modified panopeid form, subterminal tooth triangular, trunk in distal 1/4 of pleonal side bearing elongate field of heavy, rounded tubercles and granules extending to base of subterminal tooth. Male second gonopod less than one-third length of first gonopod. Applicable GenBank sequence accession numbers from
