Abstract

Discotrachytes vanharteni sp. nov. is discovered and described based on females, males and deutonymphs collected in a banana plantation in Yemen. The new species differs from its congeners in the shape of the genital shield and the sternal setae of the females. A diagnosis of the genus Discotrachytes Berlese is presented with a list of the known species. Ten Uropoda species are moved to the genus Discotrachytes: D. ehimensis (Hiramatsu, 1979) comb. nov.; D. granata (Hiramatsu & Hirschmann, 1978) comb. nov.; D. grandis (Hiramatsu & Hirschmann, 1979) comb. nov.; D. granosa (Hiramatsu & Hirschmann, 1978) comb. nov.; D. orbis (Vitzthum, 1925) comb. nov.; D. ornata (Hiramatsu & Hirschmann, 1978) comb. nov.; D. procera (Hiramatsu & Hirschmann, 1979) comb. nov.; D. procerasimilis (Hiramatsu & Hirschmann, 1979) comb. nov.; D. regia (Vitzthum, 1921) comb. nov.; D. regiasimilis (Hirschmann, 1972); and D. verrucosa (Hiramatsu, 1980) comb. nov. A new key to the known Discotrachytes species is also presented.
