The following characters are also diagnostic, though not unique to the genus: male with two rows of tubercles along lower jaw, outer row consisting of larger conical tubercles, inner row of smaller round tubercles, minute tubercles speckled across chest region, dorsal surface of head and along lower jaw, single row of minute tubercles also present along dorsal surface of the unbranched portion of branched pectoralfin rays 2–4 and around eye, forming complete ring; female with minute tubercles speckled across chest region, dorsal surface of head and along lower jaw only; dorsal-fin rays ii.5.i or ii.6.i, anal-fin-rays iii.15.i or iii.16, pelvic-fin rays i.4.i, pectoral-fin rays i.10.i, principal caudal rays 9+8; cephalic sensory canals reduced to preoperculo-mandibular canal and supraorbital canal; lateral line absent.

Etymology. – From the Greek αραιος (araios) meaning thin, slender, weak and Κυπρις (Cypris), one of the names of Aphrodite and a common suffix for cyprinid genera. Gender feminine.
