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.
