Arractocetus Kurosawa, 1985

Arractocetus Kurosawa, 1985: 112 .

Type species: Atractocerus nipponicus Nakane, 1985 (original designation).

Diagnosis. Species of Arractocetus are distinguished from other atractocerines by the head, which is declined, flattened above and abruptly declined posteriorly, the head and pronotum densely clothed with hairs, the pronotum subquadrate with a distinct median groove, and the hind wings often darkened or metallic. Eyes in this genus are very finely facetted, with individual facets flattened rather than convex.

Distrubution. Arractocetus is primarily an Oriental genus, distributed from India to Southeast Asia, Indonesia, New Guinea, northern Australia, the Philippines, Taiwan and southern Japan.

Biology. As noted by Kurosawa (1985), the eye type in this genus is indicative of diurnal habits and the colour patterns appear to mimic those of various Hymenoptera.
