Genus Platyacarus Kudon, 1982a

Twelve known species of the genus Platyacarus were described in a series of four papers by Kudon (1982a, 1982b, 1982c, 1982d). Representatives of this genus occur only on birds of the family Dendrocolaptidae . They were recorded on these hosts across Central and South America ( Kudon 1982e): Brazil (17 host species), Ecuador (three), Guyana (one), Colombia (one), Venezuela (three), Panama (two), French Guyana (one), Surinam (one), and Costa Rica (one). Mites of Platyacarus may be distinguished from other proctophyllodine genera by the following combination of characters: setae ve absent; epimerites I normally fused into a U; setae f2 absent; in males, opisthosomal lobes short, provided with terminal lamellae of triangle or tongue-shaped form; aedeagus is ensiform; genital arch is small, with strongly divergent branches; adanal shields represented by one or two pairs of small sclerites; setae g and ps3 arranged into longitudinal rectangle; legs III–IV subequal.
