Two new species of <i>Tropodiaptomus</i> Kiefer, 1932 (Copepoda, Calanoida, Diaptomidae) from temporary waters in Thailand and Cambodia with a key to Southeast Asian species.

ABSTRACT: Two new copepod species of the species-rich genus Tropodiaptomus, collected from temporary water habitats in Southeast Asia, are described. A critical morphological comparison has revealed that the two new species, T. lannaensis sp. nov. from Thailand and T. kampucheaensis sp. nov. from Cambodia, closely resemble their respective congeners, T. ruttneri (Brehm, 1923) and T. doriai (Richard, 1894). However, T. lannaensis sp. nov. can be distinguished from other congeners, including T. ruttneri, by the following characters of the male P5: (1) the inner margin of the right basis has one small semicircular knob and one triangular knob; (2) the right second exopodal segment has a long, slender accessory spine inserted at the p
