Type species.

Anachlorocurtis commensalis Hayashi, 1975.

Diagnosis.

Rostrum short, ascending in adults, reaching midlength of article 1 of antennular peduncle, terminating in acute tip or obliquely truncate distally with irregular dentition; dorsal and ventral margins usually unarmed. Carapace without supraorbital tooth; dorsal midline with two prominent processes, anterior one postrostral, irregularly denticulate anteriorly, posterior one cardiac in position, directed forward, acuminate; suborbital lobe absent; pterygostomial angle rounded, unarmed. Pleomeres 1-5 dorsally rounded; pleomeres 4 and 5 each without pair of posterolateral teeth. Pleomere 5 without deep transverse groove near posterodorsal margin; pleuron rounded posteriorly. Pleomere 6 without posteromedian tooth; posteroventral angle without tooth. Telson posterior margin truncate or rounded, with five pairs of unequal spiniform setae. Eye without ocellar spot (nebenauge); cornea with papilla-like tubercle. Antennular peduncle article 1 unarmed on dorsodistal margin; stylocerite obliquely truncate distally, both distal angles dentate; outer flagellum shorter than peduncle, distal portion reduced to one or two articles. Mandible without palp. Maxillule palp with well-developed distal outer lobule bearing apical seta. Maxilliped 1 with coxal and basial endites poorly developed, narrow; exopodal flagellum absent. Maxilliped 2 endopod with dactylus located at mesial portion of propodus or fused to propodus; exopod absent. Articulation between carpal article 1 and 2 of pereopod 2 strongly oblique. Pereopods 3-5 propodi slightly narrowing distally, with few widely spaced minute spiniform setae on flexor margin; carpi without spiniform setae on lateral surface; meri of pereopods 3 and 4 each with one spiniform seta distolaterally and one minute spiniform seta at midlength of ventral surface. Male pleopod 1 endopod with small rounded lateral lobe far exceeded by well-developed appendix interna.
