Chinius eunicegalatiae n. sp (Diptera; Psychodidae), a cavernicolous sandfly from Laos

A description is given of Chinius eunicegalatiae n. sp. (Diptera; Psychodidae) from Laos. This is the third known species belonging to the Asiatic genus Chinius Leng, 1987. Like C. junlianensis Leng, 1987 and C. barbazani Depaquit, Leger and Beales, 2006, C. eunicegalatiae n. sp. is a cavernicolous species. An absence of the R2 vein is shared with C. barbazani. A differential diagnosis with the two other known species of the genus is given. The main differential characters are the lengths of the genital filaments and of the spermathecal ducts.
