DIAGNOSIS: Distinguishable from the superficially similar specimens of
A. chondrus
,
n.sp.
, by the expansion of the elytra at the middle, and from
A. sabulous
,
n.sp.
, by the more convex condition of the pronotal side margins.
DESCRIPTION:
Size
: Length 4.0–6.0 mm; width
1.7–2.5 mm
.
Integument
: Black.
Vestiture
: Integument densely vested with prominent light and dark setae; elytral middiscal setal tuft comprised of two patches, posterior patch much shorter than anterior patch.
Head
: Finely punctate; interocular depressions and frontal umbo moderately developed; eyes oval, moderately convex; width across eyes slightly narrower than width across pronotum (40:43); antenna (fig. 218) shorter than length of pronotum (30:38).
Thorax
: Pronotum slightly longer than broad (43:48), disc finely punctate and very finely microsculptured, subapical depression poorly defined, side margins moderately arcuate; elytra moderately convex, depth at humerus 25, greatest depth in posterior half 30.
Abdomen
: Posterior margin of female pygidium evenly arcuate.
VARIATION: The specimens examined were quite homogeneous.
NATURAL HISTORY: Specimens have been collected in January, March, June, and July; from
100 to 500 m
in altitude. Two specimens were collected on
Croton
, another by beating foliage from a flowering tree.
DISTRIBUTION (map 27): Known only from central
Costa Rica
.
ETYMOLOGY: The specific epithet
cohibilis
is a Latin adjectival that translates as terse. I refer to the abbreviated condition of the posterior patch of the elytral middiscal setal tuft.
