DIAGNOSIS: Among the species that have a parameral accumination this species may be identified by the presence of a dense aggregate of pale setae on the lower sides of the pronotum. This characteristic also separates
A. bispineus
,
n.sp.
, beetles from superficial similar Chiapan members of
A. ciliaris
,
n.sp.
DESCRIPTION:
Size
: 3.5–5.0 mm; width
1.6– 2.1 mm
.
Integument
: Black, with violaceous tinge; pronotal lower sides vested with dense aggregate of pale setae; sutural tuft very reduced; midelytron with loose aggregate of setae whose orientation is towards epipleural margin.
Head
: Width across eyes equal to width across pronotum (30:30); cranium finely puctate; interocular depressions and frontal umbo shallow, eyes subspherical, moderately convex; antenna as in figure 52, as long as length of pronotum.
Thorax
: Pronotum as long as wide (30:30), considerably narrower than width of elytron across humeri (30:40), finely punctate, subapical depression faintly indicated, side margins moderately arcuate; elytra plane, depth at humeris 15, greatest depth in posterior half 15, surface shallowly rugose.
Abdomen
: Pygidial posterior margin evenly arcuate; aedeagus as in figure 194; paramere with medial acumination; apical region of tegmen with paralateral bands of serrations; phallic plicae particularly broad (fig. 195).
VARIATION: The available specimens do not vary appreciably.
NATURAL HISTORY: Specimens were collected in October.
DISTRIBUTION (map 21): Known from the Chiapan highlands of southern
Mexico
.
ETYMOLOGY: From the Latin prefix
bi
(two) and the Latin
spineus
(of thorns). I refer to the parameral acuminations on the tegmen.
