Abstract

Two new copepod species from two caves in northeastern and southern Thailand are described. Elaphoidella isana sp. nov. and Schizopera paktaii sp. nov. were collected from the unsaturated zone of freshwater pools fed only by dripping water. They are closely related to E. intermedia Chappuis, 1931 and S. validior Sars, 1909, respectively. Elaphoidella isana sp. nov. can be distinguished from its closest relative by the armature of P4 and P5, and by the ornamentation of caudal rami. Schizopera paktaii sp. nov. differs from its relative S. validior in the armature of P1, P5 and caudal rami.
