AMNH
). (Specimen point mounted; pygidium, sixth visible abdominal sternum, and machine printed sex label affixed to paper pointed; support card; locality label;
AMNH
repository label, white, machine printed; ho lotype label, red, machine printed; plastic vial with abdomen.)
PARATYPES
: None.
DIAGNOSIS: The available specimen is superficially similar to specimens of
A. naevius
,
n.sp.
In
A. humerus
,
n.sp.
, specimens, however, the elytral setal tuft is bipartite (fig. 168) and there is a more pronounced swollen humeral umbo and deeper concavity behind the humerus.
DESCRIPTION:
Size
: Length 5.0 mm; width 2.0 mm.
Integument
: Brown.
Vestiture
: Integument vested predominantly with pale setae, few dark setae; metepisternal, sutural, and elytral tufts well developed; latter bipartite, anterior patch with setae directed towards epipleuron, setae of posterior patch directed posteriorly.
Head
: Width across eyes feebly narrower than width across pronotum (24:28), very finely punctate; interocular depression and frontal umbo moderately defined; eyes subspherical, moderately convex; antenna as in figure 67.
Thorax
: Pronotum subequal in width and length (28:29), narrower than width of elytral across humeri (28:34); pronotal disc finely punctate; elytral humeral umbo very prominent; elytra concave behind humeral umbo, depth at humerus 15, greatest depth in posterior half 22.
Abdomen
: Female pygidium (fig. 114) evenly convex in posterior margin; sixth visible sternum (fig. 115) strongly incised.
NATURAL HISTORY: The only available specimen was collected from the
type
locality in July.
DISTRIBUTION (map 21): Known only from western
Honduras
.
ETYMOLOGY: The trivial name
humerus
(shoulder) is a Latin noun used here to accentuate the prominence of the swollen umbo behind the humeral angle.
