(Specimen point mounted, sex label affixed to paper point, white, hand printed; support card; locality label, white, machine printed; holotype label, red, machine and hand printed; plastic vial with abdomen and aedeagus.) PARATYPES : Eight specimens. Mexico : Chiapas : Sumidero Natl. Pk , 5­X­1990 , P. Lago & E. Zucaro ( UMIC , 1) ; 3–5 km S La Trinitaria , 19 –20­X­1988 , J. E.

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.
