Opitzia Nemésio

Type species: Arenaria chiapas Opitz, 1997: 57 . By original designation.

Diagnosis: Epiphloeine specimens belong to this genus if the seventh antennomere is acuminate (fig. 73) and the elytral sides are strongly deflexed.

Description: Size: Length 7.0–10.0 mm; width 1.8–3.0 mm. Form: Oblong subrectangulate; 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 very short, secondary (2º) setae usually pale and very densely distributed. Head (figs. 64–66): Cranium coarsely punctate; eyes moderately bulgy, finely faceted, ocular notch more angular than rounded; antenna (fig. 73) inserted at lower angle of eye incision, comprised of 10 antennomeres, loosely clubbed, scape as long as combined length of pedicel and funicular antennomeres, scape short and stout, funicular antennomeres very transverse, 5 th and 7 th antennomeres particularly acuminate, 8 th and 9 th antennomeres rectangular, 10 th antennomere oval; labrum (fig. 79) deeply incised; tormal processes horizontal and not welded; mandible (fig. 74) robust, dentes well developed, mandibular penicillus well developed; maxillary (fig. 76) and labial (fig. 75) terminal palpomeres digitiform, laterolacinia present; frons wide; gular sutures strongly converging; gular pads small. Thorax: Pronotum (figs. 71, 72) quadrate or slightly oblong, lateral tubercle prominent, 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 (fig. 80) without furcal lamina; elytra oblong rectangulate, side margins strongly deflexed, epipleuron extended to elytral apex, punctations small, grouped into distinct rows or somewhat diffusely distributed and profusely distributed; metathoracic wing not examined; 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, not incised in females. Male Genitalia (fig. 69): Aedeagus tubular; phallobasic rod present, linear, phallic plates broad; spicular fork (fig. 78) comprised of completely separated spicular plates. Male Mesodermal Reproductive Organs (fig. 77): Two pairs of accessory glands; testis comprised of about 12 follicles.

Distribution: One species is known from southern México, the second from eastern Bolivia. Evolutionary relationship: Within Epiphloeinae Opitzia Nemésio is most closely related to Hapsidopteris Opitz as discussed under the latter mentioned genus.
