Head triangular (length 0.4 mm, width 0.3 mm), base of antennal tubercle short, not longer than diameter of eye. Longitudinal sulcus wider behind eyes, spindle-shaped. Eyes kidney-shaped (diameter 0.1 mm). Antennal length 1.0 mm. Antennomere length as follows: 1 (0.08 mm), 2 (0.06 mm), 3 to 5 (0.04 mm), 6 (0.03 mm), 7 to 10 (0.06 mm), and 11 (0.2 mm), clava conspicuous. Maxillary palpi light brown, with short and even pilosity. Pronotum quadrate (length and width 0.35 mm). Lateral lobes broad, triangular. Antebasal lobe oval, at least three times wider than long. Pronotal disc oval, longitudinal and transversal sulci wider toward edges. Elytra length 0.5 mm, width 0.6 mm. Humeral teeth absent, humeral elevation present. Sutural fovea round and deep, sutural stria extending beyond middle of elytra. Basal discal fovea rounded and followed by discal depression. Abdominal segments I–V dorsally with length as follows: 0.3, 0.1, 0.1, 0.1, 0.1 (mm). Ventrally, segment V projected distally, segment VI without depression, pygidial suture not evident. Genitalia. Phallobase regular, bilobed, asymmetrical. Median lobe short, slender, asymmetrical. Two accessory lobes shorter than median lobe ( Figs. 15 B, 15C).

Type material. Holotype (male): “ Peru, Junín, Puerto Ocopa Los Olivos 11°3.00’S, 74°15.52’W. 1200 m. III- 29 to IV-1-2009. Flight intercept trap. A.K. Tishechkin” ( FMNH). Paratype: 1 male, same data as holotype ( LSAM).
