Renefouqueosis peruviensis sp. nov.

( Figs 1 a–c, 2)

Type locality. Peru, Lambayeque Region, 98 mi E of Olmos.

Type material. HOLOTYPE: ♁, ‘ PERU: 98 mi. E. Olmos Lambayeque, I-19-1955, E. I. Schlinger & E. S. Ross collectors’ ( CASC) . PARATYPE: ♀, ‘ PERU: 98 mi. E. Olmos Lambayeque, I-19-1955, E. I. Schlinger & E. S. Ross collectors. Tenebrionid Base, Aaron D. Smith, Catalog # 16893’ ( RLAC).

Description. Holotype, male: length 3.0 mm, width 1.6 mm. Integument matt, glabrous, heavily punctate, dark reddish brown.

Head broadened from base to genae lateral to eyes, widest at level lateral to eyes. Surface covered with broad, shallow punctures, each bearing a short seta, setae becoming slightly longer at apex. Eyes composed of an elongate series of facets positioned above an antero-lateral extended genal keel, rounded anteriorly, visible from above only at posterior, rest of eye facets facing anteriorly, not visible from above due to genal extension above antennal insertion. Antennae 11-segmented, antennomeres I–III longer than wide, IV–X wider than long, XI longer than wide. Antennomere (refer to Fig. 1 ) X larger than IX, antennomere XI subequal in width to antennomere IX but longer in length, width. Antennomere XI smaller than X, completely separated from antennomere X. Mentum trapezoidal, weakly transverse, apex wider than base, anteriorly concave, with sparse elongate setae; ligula visible, small. Maxillary palps with stipes, palpifer visible, apical segments elongate oval. Labial palps small. Gular region strongly produced anteriorly around mentum, anterior angles acute, apex between angles arcuate, convex. Gular sides (temples) with antero-lateral plates which covers eyes from below. Lower surface of head covered with yellow setae, longer medially.

Pronotum 1.125 times wider than long, about equally as long as head, cordate, sharply reflexed at posterior lateral angles, forming a triangular shaped spike, with longitudinal keels at about 1/5 distance to lateral margin at broadest point. Antero-lateral margins expanded, with anterior angles protruding slightly. Anterior margin rounded, posterior margin nearly truncate. Lateral margins serrate. Surface covered with broad, shallow punctures, each bearing a short seta. Lateral sides of disc clearly flattened. Lower surface strongly punctate with few short setae laterally, longer medially.

Scutellum very small, triangular.

Elytra broadly rounded, with weakly expressed rounded humeral angles, base concave before scutellum, surface deeply serially punctate, punctures with small short seta. Intervals 3, 5, and 7 forming a sharp keel; keels 3 and 7 terminate before apex; keel 5 reaching and meeting at apex of abdomen. Elytral suture also slightly elevated.

Ventral surface ( Fig. 1C ) with prosternal process narrowing behind coxae, strongly punctate, each puncture bearing moderately long yellow setae. Abdomen as in Fig. 1C , with intercoxal process of abdomen nearly parallel, truncate at apex. Surface strongly punctate bearing short setae laterally, longer medially.

Legs relatively short. Tibiae and femora straight, setose. Femora broader than tibiae. Tibia expanded gradually to apex. Abdomen punctured as elytra.

Male genitalia not dissected but genitalia partly exposed externally. Aedeagus inverted with parameres narrowing at apex, split apically.

Female genitalia not dissected but genitalia partly exposed externally (see Fig. 1 ) with coxites total length approximately equal to length of last visible abdominal segment. Gonostyli small, sub-apical with setae at apex.

Distribution. Peru: Lambayeque.

Remarks. The area mentioned on the label puts this collecting area in the dry, rain shadow areas in the mountains of Northern Peru, probably at a mid-elevation.
