Type locality. Mexico, Veracruz.
Type Holder. Canadian Museum of Nature (CMNC)
Type material. The type series consists of 9 specimens. The holotype male [dissected] is labeled as follows: Mexico, Veracruz, 4.3 mi E Huatusco, 21­vi­83, 3400', cloud forest, R Anderson (CMNC). The allotype female is labeled as follows: Mexico, Veracruz, 2.8 mi SE Tebanca, E Catemaco, 17­vi­1985, Askevold & Heffern (CWOB). The sex and label data of the paratypes are as follows:
4 males (labeled same as holotype) (CMNC); 1 female, Mexico, Vcruz [Veracruz], St. Lucrecia, F Knab collector (USNM); 1 male, Mexico, Veracruz, 7 km E Huatusco, Hwy 125, 16 July 1990, 1230 m, JS Ashe, KJ Ahn, R Leschen, ex beating (UKSC). 1 female, Guatemala, Suchit, 8 mi N Sta. Barbara, Finca Sta. [Santa] Adelaida, July 14–16, 1959, P & C Vaurie (AMNH).
Size range. Male: 4.3 x 2.3 mm to 4.9 x 2.5 mm; Female: 5.0 x 2.5 mm to 5.2 x 2.7 mm.
Description. Body testaceous to reddish­brown. Head with some minute punctures near eyes; frons bisulcate, weakly convex between sulci; vertex weakly convex; eyes reniform, not protuberant, flush with surface of head. Rostrum subequal in length to head, punctured throughout, less punctured dorsally beyond antennal insertions, twice as wide as frons at apex, slightly more than twice as wide in female; postlabial area with pair of short, widely separated, bluntly pointed projections in male. Antennae inserted near basal ¼ of rostrum; club elongate­compact, middle and terminal segments nearly subequal in length, basal segment slightly longer; funicular segment 1 ovo­globose, subequal to scape; 2 shorter than 1, clavate; 3 and 4 subequal, like segment 2 but longer; 5 and 6 subequal to segment 1; 5 slightly shorter; 7 short, moniliform. Pronotum smooth, shiny, with minute shallow punctures; anterior collar weakly defined, dorsally widened and v­shaped. Scutellum slightly wider than long, 5­sided, with some minute punctures. Elytra longer than wide, widest across humeri, in dorsal view narrowed posteriorly, with weak depression behind scutellum; humeri obliquely angled, with small acute denticle; striae small, shallow, forming line­like grooves at base, widely separated within row, becoming progressively less distinct beyond elytral base; intervals at elytral base weakly convex, becoming flat, smooth and much wider posteriorly. Profemora evenly swollen in both sexes.
Distribution (Fig. 1). All specimens are from Veracruz, Mexico except a single female from the western coast of Guatemala.
Comments. This species is very similar to O. conicollis but O. veracruensis is distinctly smaller in size and differs in head and rostral characteristics. The aedeaguses of these two species are very distinct (Figs.19 & 21).
Host plants. Host plant associations for this species are unknown.
Name derivation. The specific name is derived from the Mexican state of Veracruz where the majority of specimens were collected.
