Sueus Murayama, 1951

Sueus Murayama, 1951: 1 . Type species Sueus sphaerotrypoides Murayama, 1951 =

Hyorrhynchus niisimai Eggers, 1926 , original designation.

Diagnosis. Length 1.6–3.0 mm, 1.82–2.5 × longer than wide, body black. Sueus is distinguished by the following combination of characters: eyes completely divided without a separating carina in either sex; antennal club less than 1.5 × longer than wide, forming a slightly flattened cone; female antennal funicle five or six segmented; protibia outer apical angle produced into one conspicuous spine; procoxae widely separated; and dwarf males. Sueus can be further distinguished from the other Hyorrhynchini genera Hyorrhynchus and Pseudohyorrhynchus which have eyes completely divided and separated, in part, by a carina (males); antennal club that is 1.5–2.0 × longer then wide and flattened; antennal funicle six segmented; and males that are comparable to females in size.
