→ 2Pterygia sharply projected from lateral contour of rostrum.

→ 4-Pterygia not projected or slightly projected from lateral contour of rostrum.

Solarhinomias Yunakov & Nadein, 2006Body densely covered with lanceolate light scales and dark-brownish and suberected setae at the interstriae. Elytra with dark transverse bands. Rostral dorsum sharply widened from base to middle, medially as wide as 1/3 of frons, antennal scape long, if bent backwards surpass apical margin of pronotum. Male venter elongate. Body length 2.25-2.75 mm.

→ 3-Body sparsely covered with light piliform or narrow bifurcate scales. Rostral dorsum parallelsided, medially 1.5-2 times narrower then frons.

Rhinomias ReitterRostral sides strongly longitudinally rugose. Rostral dorsum strongly convex longitudinally, separated from frons by deep transverse depression, some narrower then frons. Tegmen with at basal half parameres connate, tegminal ring narrow, smoothly confluent with parameres, apophyses 3 times shorter or as long as median lobe (Rh. forticontis). Ventral aspect of median lobe entirely or half sclerotized, at base membranous. Spiculum gastrale r-shaped at apex. Male pygidium at dorsal side with long invagination. Body length 1.87-3.00 mm.

Eurosphalmus Yunakov & Nadein, 2006-Rostral sides distinctly finely punctate without longitudinal striae. Rostral dorsum almost flat without transverse depression at base or slightly longitudinally convex and separated from frons by weak depression, 2 times narrower then frons. Tegmen with rudiment of parameres, tegminal ring broad, apophyses of various length 3-4 times shorter or as long as median lobe. Ventral aspect of median lobe almost entirely sclerotized or entirely membranous. Spiculum gastrale T-shaped at apex. Male pygidium without or with very short invagination. Body length 2.10-3.25 mm.

Amicromias ReitterHead behind of eyes more or less constricted, body usually densely covered with wide scales. Epistomal plate of rostrum distinctly depressed. Antennal scrobes entirely visible from above. Parameres normal, free at base, as long as median lobe. Eyes lateral, strongly hemisphericaly convex. Body length 1.70-2.60 mm.

→ 5-Head behind of eyes without constriction, body densely or sparsely covered with wide or narrow scales. Epistomal plate of rostrum not depressed. Parameres rudimentary or normally developed, they are more shorter then median lobe.

→ 6Claws appear free, connate at base only.

→ 7-Claws connate in basal half.

Bosporomias Yunakov et KorotyaevFrons strongly flattened. Antennal funicle very thin, 7th antennomere of funicle as long as wide, club elliptic, sharply separated from funicle. Rostral dorsum narrowed apically, strongly convex longitudinally, with narrow median sulcus, distinctly separated from frons by transverse depression. Epistome strongly convex. Body scaling very dense with grayish wide lanceolate scales and erected wide curly setae. Body length 2.40- 2.50 mm.

Turanomias Yunakov & Nadein, 2006-Frons weakly convex. Antennal funicle thin, but 7* antennomere strongly transverse, club egg-shaped. Rostral dorsum widened apically, almost flat, without median sulcus, not separated from frons by transverse depression. Epistome flat. Body scaling sparse with light piliform scales and erected thin setae. Body length 2.60-3.05 mm.

Brachysomus SchoenherrUpper side of body with more or less sparsely spaced scales, which usually incompletely cover the integument; if the scales entirely cover the integument, then antennae long and antennal scape slightly curved, evenly widened to apex. Interstrial setae uniformly shape and length. Body length 1.50-4.25 mm.

Archeophloeus Iablokoff-Khnzorian, 1959-Upper side of body densely covered with round grey-brownish scales, wliich entirely cover the integument. Antennae broad, scape sharply widened apically and strongly curved. Interstrial setae obtuse at base and disk of elytra thin shorter then interstrial width, at apical descent setae longer and wider, as long as interstrial width. Body length 2.12-3.00 mm.
