Abstract: Cyphochilus backy sp. nov., C. dongkinh sp. nov., and C. genevievae sp. nov. are described after the study of 795 specimens from Indochina. These species are largely distributed in Thailand, Laos, and Vietnam, marginally in southern China and Myanmar. They were confused until today with C. tonkinensis Brenske, 1903 for which the lectotype is designated. The parameres and distribution of the four species treated are illustrated. The use of Cyphochilus dongkinh sp. nov. as human food is documented in northern Laos. |
