Description. Body: stout; brown; integument semi-dull; a dark longitudinal strip covering pronotum, and elytra; vestiture long gold semi-decumbent; length 6.0 mm, width 2.0 mm; PEI: 2.7, (n ¼ 6).

Head: convex; frontoclypeal carina region sloping downward; clypeus and labrum with long setae erect; labrum 2 3 as long as wide; antennomera 2 through 9 serrate, antennomere 9 exceeding pronotal posterior angles, [AP: 8-7-10-10-10-10-11-11-10-13], ( Fig. 9 ). Prothorax: strongly convex; areolate, sides sinuate; base straight; pronotal posterior angles straight; prosternal lobe broadly curved, strongly bent; prosternum strongly convex; posterior angle or tip of the hypomeron bent inside, carina lateral, not meeting with hypomeral carina; pronotosternal suture sinuate, one spurious carina basally; hypomeron rugulose, bi-excavate, antennal groove simple ( Fig. 17 ); prosternum at procoxae marginate, and slightly elevated; procoxal distance 2.0 3 procoxal diameter, pronotosternal spine length 0.7 3 procoxal diameter.

Scutellum : U-shaped, vestiture semi-decumbent, long, yellow; mesocoxae separated by 0.3 3 mesocoxal diameter; posterior margin of mesosternal cavity extending posteriorly 0.4 3 mesocoxal diameter.

Elytra: interstria rugulose, slightly convex; striae pitted, pits irregular and confluent; elytral apex rounded. Leg: yellowish brown; tarsomere 4 similar in length to tarsomere 1, [TP: 39-20-14- 7-20], ( Fig. 25 ).

Male genitalia: aedeagus 2.5 3 as long as wide; median lobe parallel-sided; ( Fig. 30 ).

Type Material. Holotype: male, CHILE, Contulmo , 6.0 mm in length, [ ETA] . Paratypes here designated 3 males and 3 females: CHILE, Contulmo , 16. XII. 1985, L. E. Peña. [ ETA] .

Distribution. Contulmo, VIII Region, Chile, ( Fig. 34 ).
