Abstract
    A new Halacaridae species of the genus Copidognathus that was collectedamong the sediment between the coral algae Halimeda opuntiafrom Chiriatapu (Andaman Island, India, Bay of Bengal) is described.Copidognathus andamanensis sp. n. is closely related to the membersof the Copidognathus bairdi species group and can be assigned to thisgroup. Major diagnostic characteristics of C. andamanensis sp. n. are -ADwith one anterior, one middle (due to fusion of two areolae medially)and one marginal areola (posteriorly); PD with four costae, middle andparacostae joined anteriorly; middle costae three rosette pores and paracostaetwo rosette pores wide; PD with two gland pores posterioly; EP notdeveloped; tibia I with three ventral setae of which ones is pectinate;Patella IV with four setae; telofemora III and IV devoid of any ventralseta; tibia IV with all ventral setae smooth; tarsi III and IV with fourdorsal setae; lateral claws of leg II-IV with 3-5 strong tooth ventrally. Inthe male PGS start a little bit below the anterior margin of GA.C. andamanensis sp. n. is closely related to C. gangliollatus NEWELL1984 although some dissimilaties can be reported. In this context, thedescription of the latter species is also discussed.
