description: Alloscolytroproctus peruanus Hustache
(Figs. 1, 4, 7–9)
Alloscolytroproctus peruanus Hustache, 1929: 231 (type locality Marcapata, Peru); Wibmer & O’Brien 1986: 366. Brenthidomimus hartmanni Guenther, 1943: 90 (type locality Marcapata, Peru); Kuschel 1955: 280 (syn.); Wibmer & O’Brien 1986: 366.
Diagnosis
Length 3.4–7.5 mm. Integument black except for red posterior elytral maculation, some specimens also with red anterior maculation and prosternum and portions of legs rufous. Rostrum with apex not or only very slightly expanded, width at apex slightly less than distance between eyes. Pronotal disc (Fig. 4) with punctures deep, separated by at least their own diameter, rarely slightly less, but not subcontiguous. Elytral interval 2 (Fig. 4) with extremely dense, very fine, erect pilose vestiture along length from anterior half to declivity, similar (but shorter) vestiture also on intervals 3, 5 and 9 at declivity. Hind tibiae with large tooth at inner apical angle curved towards apex and hook-like.

Distribution
Extreme southern Panama (Darien) to western South America.
Biology
Specimens have been collected in flight intercept traps in forests ranging from lowland rainforest at 200 m (Peru) to montane cloud forest at 1450 m (Panama). One specimen was collected in yungas forest in Bolivia at 2550 m. Nothing is known of its natural history.
Comments
One paratype of Alloscolytroproctus peruanus from Marcapata, Peru, (NZAC) has been examined, but no types of Brenthidomimus hartmanni. Kuschel (1955) placed Brenthidomimus hartmanni as a junior synonym of Alloscolytroproctus peruanus, and this synonymy is followed here. Both taxa were described from Marcapata, Peru, likely from the same series of specimens, and one additional specimen from this locality has been examined. The species is generally larger than the others in the genus, the pattern of extremely dense, fine elytral vestiture along interval 2 (Fig. 4) is distinctive and there are only posterior red maculations in many specimens. Some specimens from Peru and Brazil are smaller and have both posterior and anterior red elytral maculations but otherwise appear conspecific with specimens from elsewhere throughout the range. The extent and density of the elytral vestiture also appears to be related to size, larger individuals having a longer row of denser vestiture along interval 2 and a denser vestiture on intervals 3, 5 and 9. Despite this variation, only one species is recognized here.
