<i>Thermocyclops dumonti</i> sp. n. (Crustacea, Copepoda), from a Temporary Waterbody in China
Abstract
Abstract Six species of the genus Thermocyclops have hitherto been known from Chinese freshwaters. A new species is here recorded from a sample collected from an eutrophic pool in central China. It is described and compared using classical morphology and mapping of its pore signature. Thermocyclops dumonti differs from T. kawamurai by absence of ornamentation on prominences of intercoxal plates of P 1 ‐P 3 , by relative length of apical spines of Enp 3 P 4 and caudal ramus. It differs from T. dybowskii by ornamentation of P 4 intercoxal plate, relative length of Enp 3 P 4 and caudal ramus, by shape of Tmi. As in other species of Thermocyclops , the perforations are bilaterally symmetrical and, species‐specific patterns occur on the cephalosome, metasome, and urosome. Conserved patterns are found elsewhere on the rostrum, cephalosome, metasome, and furcal branches. Based on pore pattern, Thermocyclops dumonti is separated from two close relatives, T. schmeili and T. dybowskii .
