Abstract

The new genus, Cerogamasus gen. nov., with the type species Cerogamasus tibetensis sp. nov., is established. The new genus is easily distinguished from other genera of Parasitidae because the dorsal idiosoma in both sexes bears more than 40 pairs of setae, of which fewer than 7 pairs of podonotal setae are smooth; the seta z5 of the dorsal hexagon is similar to j5 and j6 in form (pilose or distally pilose) while different in length (z5 longer); the seta al of the palpfemur is pectinate, and al1 and al2 of the palpgenu are entire; the gnathotectum is trispinate; peritrematal shields in females are posteriorly free; and the palptrochanter in males has a pointed ventral protuberance. C. anhuiensis sp. nov., C. guizhouensis sp. nov. and C. multidentatus sp. nov. are described based on adult samples; C. tibetensis sp. nov. is described based on deutonymph and adult samples. Cycetogamasus coreanus Athias-Henriot, 1980, is transferred to Cerogamasus gen. nov. as a new combination.
