DIAGNOSIS: Distinguishable from other species of
Aphelocerus
that have the pronotal disc microsculptured by the extent of development of the posterior patch of the elytral middiscal tuft (fig. 239).
DESCRIPTION:
Size
: Length
3.5–4.8 mm
; width
1.3–2.2 mm
.
Integument
: Black.
Vestiture
: Integument densely vested with prominent light and dark setae; elytral middiscal setal tuft comprised of two patches, posterior patch much wider than anterior patch.
Head
: Finely punctate; interocular depression and frontal umbo moderately developed; eyes oval, moderately convex; width across eyes slightly narrower than width across pronotum (33:38); antenna shorter than length of pronotum (30:38).
Thorax
: Pronotum as long as wide (38:38), disc finely punctate and very finely microsculptured, anterior transverse depression poorly defined, side margins moderately arcuate; elytra moderately convex, depth at humerus 22, greatest depth in posterior half 25.
Abdomen
: Posterior margin of pygidium evenly arcuate in female, truncate in male.
Male genitalia
: As in figure 199; parameral apices accuminate.
VARIATION: The specimens examined were quite homogeneous.
NATURAL HISTORY: Frank T. Hovore collected all the available specimens during June, on blossoms of
Croton
. One specimen was collected with a Malaise trap located at
300–
350 m
.
DISTRIBUTION (map 27): Known only from southernmost province of
Costa Rica
.
ETYMOLOGY: The specific epithet is a Latin adjective that stems from
sabulo
(gravel). I refer to the gravellike microsculpture on the pronotal disc.
