Remarks. Within the genus Cryptonura , C. dohezarensis sp. nov. most closely resembles C. persica Smolis et al. 2012 from Iran . Both taxa have similar chaetotaxy of central area of the head (chaetae A, C and D present), maxilla and mandible shape, the number of chaetae Di on Th I, similar dorsal chaetotaxy of abdomen (see Tab. 5 ). However, they clearly differ in the body colour (in C. dohezarensis , white; in C. persica , blue), the shape of dorsal tubercles (in C. dohezarensis , rounded; in C. persica , triangular), the fusion of Cl and Af tubercles on head (in C. dohezarensis , separate; in C. persica , fused) and the number of Di chaetae on Th II–III (in C. dohezarensis , 3; in C. persica , 2). C. dohezarensis sp. nov. is also similar to two species without body pigment and with rounded dorsal tubercles: C. anthrenoidea ( Ellis, 1976 ) from Greece and C. jubilaria Smolis, 2002 from Poland . Nevertheless, the new species can be easily distinguished from them by the number of L+So chaetae on head (in C. dohezarensis , 8, in C. anthrenoidea and C. jubilaria , 7), the number of L chaetae on Abd IV (in C. dohezarensis , 6, in C. anthrenoidea and C. jubilaria , 5) and a combination of characters: unguis without inner tooth, mandible with 3 teeth, 6 Vi ventral chaetae on head, chaetae C, D and E present on head, 3 Di chaetae on Abd V and 5 De+Dl+L ordinary chaetae on Abd V. The main diagnostic characters of these species are summarized in Tab. 5 .
