Type material. Holotype, male: PERU: Loreto, Panguana, pitfall trap, 16– 30.07.1984, leg. M. Verhaagh, (UIC). Paratypes: PERU: 1 male with same data as holotype, 1 female, pitfall trap, 0 7.08.1975, leg. W. Hanagarth, clear cut forest with Manihot, #9.2.4 (UIC).
Diagnosis. In M. hanagarthi the elytra are bicoloured similar to M. tricolor and M. elytrata. Additionally, in M. hanagarthi the male mesotibia resemble M. tricolor in the short size of the apical comb. Mimogonia hanagarthi is slightly smaller than M. tricolor and has the eyes less prominent than in M. elytrata. Mimogonia hanagarthi mainly resembles the newly described M. hermani in body colour and size, but the microsculpture of the elytra is slightly weaker in M. hermani than in M. hanagarthi (Fig. 5 B). An identification of this species without examination of the aedeagus is difficult.
Description. Body length 2.0 mm.
Body colour head dark brown with yellow clypeus; pronotum and anterior half of elytra yellow; posterior half of elytra darkened with posterior edge dark brown; four anterior visible segments of abdomen light red, posterior segments light brown, legs and antennae yellow.
Head 0.20 mm long, 0.37 mm wide; eyes slightly prominent and as long as temples, setiferous punctation distinct, but not deep, average distance between punctures half as wide as diameter of punctures, setae pointing posteriorly, surface with reticulate microsculpture and weak gloss.
Antennae with oblong 2nd antennomere, conical 3rd antennomere as long as 2nd, 4th antennomere slightly wider than long, the following antennomeres increasing in width, 8th antennomere 2.5 times as wide as long, 10th antennomere twice as wide as long (Fig. 3 B).
Pronotum 0.30 mm long, 0.40 mm wide; sides in front of posterior emargination smoothly rounded, setiferous punctation as deep and large as on head, but denser, average distance between punctures smaller than diameter of punctures, setae pointing to the middle, an indistinct depression in front of posterior edge on each side of the impunctate midline; surface with reticulate microsculpture, slightly glossy.
Elytra 0.47 mm long, 0.45 mm wide; with weak setiferous punctation (Fig. 5 B), setae pointing posteriorly; reticulate microsculpture deep, much deeper than on head and pronotum and thus surface matt.
Abdomen with weaker setiferous punctation and microsculpture than on forebody, surface glossy.
Mesotibia of male widest near the middle, distinctly narrowed towards apex, at inner side with a short comb of long setae (Fig. 3 C).
Aedeagus with a large hook-like structure at apex and very short paramera that are not longer than the hook-like apex of the central lobe (Fig. 3 D).
Etymology. The species is named in honour of Dr. Werner Hanagarth, who studied the Peruvian ecosystems in the Amazon valley and who passed away too early.
