Hapsidopteris Opitz

Type species: Hapsidopteris diastenus Opitz, 1997: 63 . By original designation.

Diagnosis: Specimens of this monotypic genus have an antennal club that appears to be comprised of four antennomeres (fig. 2).

Description: Size: Length 5.0 mm; width 2.0 mm. Form: Oblong rectangulate; elytra about three times longer than wide, posterolateral margin gradually curved towards elytral apex. Vestiture: Body profusely vested with short setae, elytral primary (1º) setae short, secondary (2º) setae reclinate, usually pale and very densely distributed. Head: Cranium coarsely punctate; eyes small, moderately bulgy, finely faceted, ocular notch more angular than rounded; antenna (fig. 2) inserted at lower angle of eye incision, comprised of 10 antennomeres, loosely clubbed, scape short and robust, funicular antennomeres variously developed, 3 rd large triangular, 4 th transverse rectangulate, 5 th small transverse, 6 th very large quadrate, 7 th very small transverse, 8 th subrectangulate, 9 th triangular, and 10 th oval; labrum deeply incised; mandible robust, dentes well developed; maxillary and labial terminal palpomeres digitiform; frons wide; gular sutures strongly converging; gular pads small. Thorax: Pronotum (fig. 3) quadrate, lateral tubercle small, disc coarsely punctate, pronotal arch not evident, anterior margin slightly convex, posterior margin transverse, anterior transverse depression not evident, discal trichobothria set in depressions; lateral carina not extended to anterior margin of pronotum and posteriorly confluent with pronotal bead; procoxal cavities open; interprocoxal process linear, not laterally expanded distally; metendosternite without furcal lamina; elytra oblong rectangulate, side margins strongly deflexed, epipleuron extended to elytral apex, punctations small, grouped into distinct rows; metathoracic wing as in figure 4; mesoscutellum quadrate; 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. Male Genitalia: Aedeagus tubular; phallobasic rod present, linear, phallic plates broad.

Distribution: This monotypic genus is known from southern México.

Evolutionary relationships: It is postulated that Hapsidopteris Opitz has a sister group relationship with Opitzia Nemésio. The synapotypies that bind these genera are: eyes reduced in size, anterior third of elytral sides strongly deflected, and hind pronotal angles acute.
