Holotype: ♀. Type locality: Colombia, Boyaca, SFF Iguaque, Qda. Los Francos, Malaise , 13-31- III-2003, P. Reina ( FSCA) . Paratypes: 2 specimens. Colombia: Departamento de Boyacá, SFF Iguaque , Qda.

D i a g n o s i s: Within Megatrachys OPITZ, this is the only known species whose specimens lack a cranial wisp of black setae.

D e s c r i p t i o n: Size: Length 6.5 mm; width 2.0 mm. Form: As in Fig. 302 . Color: Cranium and pronotum dark castaneous; antennae bicolorous, scape testaceous, remainder of antenna brown; pterothorax and abdominal sternites black; elytra mostly brown, side areas dark brown, with short wisps of black setae; legs bicolorous, femora, tibiae, and tarsi with portions of yellow and brown. Head: Cranium coarsely sculptured, highly setose; antenna ( Fig. 69 ) capitate, funicular antennomeres filiform, progressively shorter towards capitulum, capitular antennomeres 8 and 9 triangular, antennomere 10 ovoid; eyes large, finely facetted, eye slightly narrower than frons (EW/FW 25/28). Thorax: Pronotum ( Fig. 131 ) quadrate, highly setose, somewhat corrugated, disc deeply concave paralaterally near pronotal collar; discal and lateral trichobothria well developed (PW/PL 70/70); elytral disc corrugated; asetiferous punctures large and randomly distributed, small brown and yellow setal wisps present throughout elytral disc (EL/EW 290/55); anterior margin of protibia with 4 spines. Abdomen: Pygidium scutiform.

Variation: The available specimens are quite homogeneous.

N a t u r a l H i s t o r y: The available specimens were collected in a Malaise trap during periods of 13-31-III, 30-VII-17-VIII, and 17-VIII-1-IX.

D i s t r i b u t i o n: ThisspeciesisknownfromColombia.

E t y m o l o g y: The trivial name, irrasis, is a Latin adjective derived from irrasus (= unpolished); with reference to corrugated condition of the surface of the pronotal and elytral discs.
