Differential diagnosis
Barbutia arasbaraniensis sp. nov. is easily separated from other species of the genus Barbutia with combination of following characters: 1) with 2 pairs (vs. 3 pairs) of aggenital setae, 2) tarsus I with 1 (instead 2) solenidion, 3) femur I with 3 (vs. 4) setae, and 4) genu I with 3 + κ (vs. 5 + κ).
