An illustrated description of a new species, Heliodiaptomus phuthaiorum n. sp., from nine of the 456 sampled localities in northeast Thailand, is presented. Morphologically, it is closely related to the Indian H. pulcher ( Gurney , 1907). The new species is characterized in the male by the prominent, spinulose knob on the inner margin of the right basis; the finely serrated inner margin of the right second exopodite‐segment; and the extraordinary large, tongue‐like projection on proximal inner margin of the left basis. In the female, the genital somite is unusually long, much longer than the other two urosomites combined. This new species is rare and has been found only in temporary ponds in Nakhon Pranom and Nong Khai Provinces. It usually co‐occurs with 1–5 other diaptomids; the most frequently co‐occurring species are Neodiaptomus blachei ( Brehm , 1951), N. yangtsekiangensis Mashiko , 1951 and Eodiaptomus phuphanensis Sanoamuang , 2001.
