Pteroferus , new genus

Type species: Pteroferus zolnerowichi , new species. By present designation.

Diagnosis: Specimens belong to this genus if they are characterized by having 11 antennomeres, have a short body (about 4.4 mm) and somewhat triangular body form, and have corrugations on the elytral disc.

Description: Size: Length 4.0–5.0 mm; width 1.5–1.8 mm. Form: Oblong short triangular; elytra a little less than three times longer than wide, posterolateral margin sharply curved towards elytral apex. Vestiture: Cranium and pronotum vested profusely with yellow setae; elytral disc vested with primary (1º) setae and sec- ondary (2º) setae, 1º setae stout, erect, and dark, 2º setae short, decumbent, and yellow or brown, latter may be matted onto shallow ridges. Head (figs. 108, 109): Cranium rugosely punctate; eyes very bulgy, finely faceted, ocular notch (fig. 108) angle rounded at innermost point; antenna inserted at lower angle of eye incision, antenna (fig. 118) comprised of 11 antennomeres, loosely clubbed, scape as long as combined length of pedicel and antennomeres 3–5, scape curvate, funicular antennomeres subfiliform, 9 th and 10 th antennomeres narrow triangular, 11 th antennomere oval; labrum (fig. 116) deeply incised; tormal processes horizontal and not welded; mandible (fig. 114) robust, dentes well developed, mandibular penicillus well developed; maxillary (fig. 113)and labial (fig. 119) terminal palpomeres digitiform, laterolacinia present; frons very wide; gular sutures strongly converging; gular pads very small. Thorax (figs. 123–124): Pronotum transverse, disc highly undulating; lateral tubercle prominent, disc punctations not prominent, pronotal arch anterior margin recurved, anterior somewhat projecting, posterior margin transverse, anterior transverse depression well developed, paralateral tumescences usually prominent, depressed obliquely at sides where discal trichobothria are prominent; pronotal projection (fig. 123) slightly extended to middle; lateral carina not extended to anterior margin of pronotum and posteriorly confluent with pronotal bead; procoxal cavities open; interprocoxal process linear (fig. 123), not laterally expanded distally; metendosternite (fig. 117) without furcal lamina; elytra oblong rectangulate, epipleural margins diverging giving elytra a triangular shape, epipleuron margin minutely serrate, extended to elytral distal four-fifth, punctations small, oval, and profusely distributed on elytral disc; metathoracic wing as in figure 110; mesoscutellum triangular; tibial spur formula 0-1-1, tarsal pulvilli formula 3-3-2, anterior margin of tibia spinous; tarsal claws with large basal denticle. Abdomen: Narrows to posterior, six visible sterna; pygidium transverse, sixth visible sternum incised distally in males, not incised in females. Male Genitalia: Aedeagus (fig. 115) long and narrow; phallobasic rod present, linear, phallic plates very narrow; spicular fork as in figure 115a.

Distribution: This genus is known only from Brazil.

Etymology: The generic name is a compound name that stems from the Greek pteron (= wing) and the Latin ferus (= rough). I refer to the rough sculpturing on the elytra.

Evolutionary relationships: Pteroferus is most closely allied to those epiphloeine genera with 11 antennomeres that lack the basal portion of the MP1 vein. The sister taxon of Pteroferus is unknown at this time.
