Two new species of Cypricercinae McKenzie, 1971 (Crustacea: Ostracoda) from Thailand

Two new species of the subfamily Cypricercinae McKenzie, 1971 are described from Western part Thailand: Pseudostrandesia ratchaburiensis sp. nov. and Strandesia prachuapensis is mainly characterized by a flange on antero-ventral left valve (LV), markedly large ? seta mandibular (Md) palp, serrated bristles third endite maxillula (Mx1), slender caudal ramus (CR) with long claw Ga (length ca half that ramus) relatively low number (13) spiny whorls in Zenker’s organ. The discovery both males females present study constitutes first report sexual population this genus, thereby allowing for comparison male reproductive organs (hemipenis organ) those other genera Cypricercinae. most closely related to odiosa (Moniez, 1892) flavescens Klie, 1932 as they bear similar anterior flanges right (RV). key diagnostic features carapace (ca 1.5 mm), an angulated LV, weak small inner list RV, aesthetasc Y second antenna, Md-palp, smooth Mx1 CR short ? ramus). In addition, complexa (Victor & Fernando, 1981) comb. here proposed.
