Van text Zootaxa 2018 2018-07-02 4442 2 241 261 journal article 29759 10.11646/zootaxa.4442.2.3 7df6de8f-ad39-4865-95a7-4b2d53687a21 1175-5326 1303084 2C4367F2-0CD7-4559-8BBE-48948858F48D Genus Halocaridinides Fujino & Shokita, 1975 Halocaridinides Fujino & Shokita, 1975 : 106 . Palauatya Hart, 1980 : 481 . Amended definition. Rostrum unarmed. Supraorbital, antennal and pterygostomian spines absent. Telson broad, with two pairs of dorsal spines. Eyes reduced. Carpus of first two pereiopods excavated anteriorly. Palm of chelipeds distinct. Exopods absent from all pereiopods. Epipods on first three pereiopods. Pleurobranchs on first four pereiopods. First male pleopod without appendix interna. Uropodal exopod ending in a tooth. Diaeresis with one to several movable spines. Type species . Halocaridina ( Halocaridinides ) trigonophthalma Fujino & Shokita, 1975 . Remarks . As there is no concensus on the delimitation of subfamilies within the Atyidae , subdivision has been abandoned ( De Grave et al. 2009 , De Grave & Fransen 2011 ). Von Rintelen et al . (2012) did not recover these subfamilies in their phylogeny of atyid genera. Instead of using subfamilies they recognized five groups of genera based on their phylogenetic reconstruction. The anchialine Typhlatya group comprises Halocaridinides , Halocaridina Holthuis, 1963 , Typhlatya Creaser, 1936 , Stygiocaris Holthuis, 1960 and Antecaridina Edmondson, 1954 .
