Pennasolis , new genus

Type species: Phyllobaenus merkeli Horn, 1896: 374 . By present designation.

Diagnosis: The paralateral-elongated depressions on the sides of the elytral disc will distinguish the members of this genus. Additional diagnostic characteristics involve the pronotal setae, which are set on papillose elevations, the subequal antennal club antennomeres are particularly small, the head is extraordinarily transverse, and the phallobasic apodeme is very short.

Description: Size: Length 4.8–6.0 mm; width 1.7–2.0 mm. Form: Oblong short rectangulate; elytra little less than three times longer than wide, posterolateral margin gradually curved towards elytral apex. Vestiture: Cranium vested profusely with stout pale setae; pronotum vested with porrect stout setae; elytral disc vested with primary (1º) setae and secondary (2º) setae, 1º setae stout, erect, and dark, particularly conspicuous along epipleural and sutural margins, 2º setae short, decumbent, white or yellow. Head (figs. 82–84): Extraordinarily transverse; cranium finely rugosely punctate; eyes very bulgy, finely faceted, ocular notch angle acute (fig. 82) at innermost point; antenna inserted at lower angle of eye incision, antenna (fig. 86) comprised of 10 antennomeres, loosely clubbed, scape as long as combined length of pedicel and antennomeres 3-5, scape curvate, pedicel oval; funicular antennomeres 3--6 subfiliform, 7 globose, club antennomeres, small, subequal; labrum (fig. 89) deeply incised; tormal processes horizontal and not welded; mandible (fig. 87) robust, dentes well developed, mandibular pinicillus well developed; maxillary (fig. 92) and labial (fig. 88) terminal palpomeres digitiform, laterolacinia present; frons very wide; gular sutures arcuate (fig. 83), disc strongly converging; gular pads very small. Thorax: Pronotum (figs. 81, 85) transverse, lateral tubercle not present, disc finely highly undulating, pronotal arch rough, anterior margin slightly pointed medially, posterior margin transverse, side margins minutely serrated, anterior transverse depression notable only at pronotal lateral margins, disc of pronotal proper with elevations and depressions, depressed extensively at sides where discal trichobothria are prominent; pronotal projection (fig. 81) slightly extended to middle; lateral carina extended to anterior margin of pronotum and posteriorly confluent with pronotal bead; procoxal cavities open; interprocoxal process linear (fig. 81), not laterally expanded distally; metendosternite (fig. 90) without furcal lamina; elytra short oblong rectangulate, epipleural margins subparallel then gradually becoming more rounded, then gradually converging towards sutural margin, epipleuron extended to elytral distal four-fifth, punctations profusely distributed on elytral disc; metathoracic wing as in figures; mesoscutellum subglobose; tibial spur formula 0-1-1, tarsal pulvilli formula 3-3-1, 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 (fig. 93): Aedeagus tubular; phallobasic rod present, linear, phallic plates very narrow; spicular fork as in figure 91. Male Internal Reproductive Organs (fig. 94): Two pairs of accessory glands.

Distribution: Known only from western USA.

Etymology: The generic name is a Latin compound name that stems from the noun penna (-wing) and the Latin noun sol (= sun), and the Latin suffix – is (= having the nature of). I refer to the light coloration on the elytral disc of the type species.

Evolutionary relationships: This North American genus is most closely allied to the Middle American genus Megatrachys .
