AA504E5FAC244B3CFE094BD2FE5B6929.taxon	description	(Figs. 1, 3 – 5) Description. Holotype, male. Oblong­oval, flattened, piceous, entire dorsal surface dull and microreticulate (Fig. 1). Head with transverse impression behind clypeus; clypeus swollen and with truncate anterior margin; genae prominently raised above antennal insertions, coarsely and densely punctured; eyes reniform, dorsal lobe slightly larger than ventral; antennae almost attaining pronotal base, terminal segment tomentose at apex (Fig. 3), subapical segment with tomentose patches on both sides of apex (Fig. 3); mentum transverse, apical margin broadly emarginate; terminal segment of maxillary palpus large, scalene. Pronotum slightly longer than broad (Fig. 1), widest before middle, lateral marginal bead thin, subparallel, sinuate in basal half, apical margin deeply emarginate, angles acute and prominent, basal margin feebly bisinuate, angles acute but not prominent, surface discretely punctured medially, punctures becoming larger and somewhat rugose laterally (Fig. 1). Elytra broad, flattened, uniformly subconvex from side to side, lateral margins strongly costate, reflexed at base and almost attaining apex, gradually disappearing on apical declivity (Fig. 1); epipleura poorly defined basally until about middle of third visible abdominal sternum from which point it is strong and sharp to elytral apex, entire surface dull with very small granules separated by several times their diameters. Hypomeron and prosternum uniformly finely, deeply and sparsely punctate; prosternal process strongly convex between procoxae, its apex broad and truncate; mesosternum coarsely and rugosely granulate, anterior face not excavate; coxae all widely separated; intercoxal margin of basal abdominal sternum rounded; abdominal sterna finely but not densely granulate except at apex of terminal sternum where granules are closer together. Legs very slender, coarsely and densely punctured. Length: 14.5 mm; width: 6.7 mm. Male genitalia. Rods of sternum IX nearly touching at basal half. Dorsal membrane of proctiger with setae on distal quarter. Lateral styles of tegmen with anteroventral margin strongly bisinuate, widest at middle (Fig. 5), with setae on distal quarter of ventral surface (Fig. 5). Median lobe proximally broadened (Fig. 4). Variation. All four males of the type series are very similar in size, shape and luster. The female is slightly longer and broader (L: 15.5 mm; W: 7.2 mm) but otherwise not significantly different from the males.	en	Triplehorn, Charles A., Flores, Gustavo E.

AA504E5FAC244B3CFE094BD2FE5B6929.taxon	materials_examined	Types. Holotype, male: Arizona, Pima County, Kitt Peak, 3 ­ VII­ 1984, C. A. Olson (USNM, Smithsonian Institution, Washington, D. C.). Four paratypes: one male same data as holotype (UAIC, University of Arizona, Tucson), two males same locality as holotype except 20 ­ VII­ 1984 (OSUC, Ohio State University, Columbus OH), one female same locality as holotype except 22 ­ X­ 1982 (UAIC). These specimens were likely collected in pitfall traps (C. A. Olson, pers. comm.)	en	Triplehorn, Charles A., Flores, Gustavo E.

AA504E5FAC244B3CFE094BD2FE5B6929.taxon	etymology	Etymology. We take pleasure in naming this interesting species in honor of Carl A. Olson, who collected the type series.	en	Triplehorn, Charles A., Flores, Gustavo E. (2002): Two New Species Of Asidopsis Casey From Arizona And Chihuahua, Mexico (Coleoptera: Tenebrionidae: Asidini).

AA504E5FAC244B3CFE094BD2FE5B6929.taxon	discussion	Discussion. Asidopsis olsoni superficially resembles A. macra (Horn) in general body configuration, especially in the shape of pronotum, which is longer than broad (in all other species of Asidopsis, the pronotum is broader than long). It differs in the distinct cariniform lateral margins of the elytra, dull and minutely granulate elytral surface, and the punctation of the pronotum (rugose laterally and basally).	en	Triplehorn, Charles A., Flores, Gustavo E.

AA504E5FAC264B3AFEE24C08FBFD6931.taxon	description	(Figs. 2, 6 – 8) Description. Holotype, male. Oblong­oval, convex, piceous, dorsal surface shining (Fig. 2). Head with triangular impression behind clypeus which is swollen and with truncate anterior margin; genae prominently raised above antennal insertions, coarsely but not densely punctured, punctures well­separated, becoming smaller posteriorly; eyes narrowly reniform, dorsal lobe slightly larger than ventral; antennae short, stout, extending only slightly behind middle of pronotum; terminal segment tomentose at apex (Fig. 6), subapical segment with continuous tomentose band (Fig. 6); mentum cordiform, apical margin shallowly emarginate; terminal segment of maxillary palpus large, scalene. Pronotum slightly broader than long (Fig. 2), widest at middle, lateral margins thick, subparallel, not reflexed, apical margin deeply emarginate, angles acute and prominent, basal margin strongly bisinuate, angles acute, prominent, overlapping base of elytra, surface minutely and sparsely punctate medially, punctures becoming larger and somewhat rugose laterally (Fig. 2). Elytra broad, convex, lateral margins smoothly rounded from side to side, humeral angles abruptly narrowly expanded, receiving acute pronotal angles (Fig. 2); epipleura not evident until about middle of third visible abdominal sternum; entire surface shining, finely and sparsely punctate, propleura smooth, almost impunctate except along margins; prosternum finely, shallowly and rugosely punctate; prosternal process strongly convex between procoxae, the apex narrowing posteriorly; mesosternum shallowly, rugosely punctate, anterior face not excavate; coxae all widely separated; intercoxal margin of basal abdominal sternum rounded; abdominal sterna shallowly, finely punctured with faint longitudinal wrinkles, terminal sternum more densely punctured, forming horizontal wrinkles. Length: 15.6 mm; width: 6.2 mm. Male genitalia. Rods of sternum IX nearly touching at basal third. Dorsal membrane of proctiger with setae on distal 1 / 5. Lateral styles of tegmen with anteroventral margin bisinuate, widest at base (Fig. 8), with setae on distal quarter of ventral surface (Fig. 8). Median lobe not broadened proximally (Fig. 7). Variation. The four paratypes are not much different from the holotype except for the size. The female is 17.3 mm in length and 7.0 mm in width. The same measurements for the male paratypes are: 13.0 – 13.8 mm in length and 5.6 – 6.0 mm in width.	en	Triplehorn, Charles A., Flores, Gustavo E.

Heinz (SMNS, Staatliches Museum für Naturkunde, Stuttgart, Germany). Four paratypes same data as holotype: one female (SMNS), one male (USNM, Smithsonian Institution, Washington, D. C.), two males (OSUC, The Ohio State University, Columbus OH).	en	Triplehorn, Charles A., Flores, Gustavo E.

AA504E5FAC264B3AFEE24C08FBFD6931.taxon	etymology	Etymology. The name refers to the abruptly expanded humeral angles of the elytra.	en	Triplehorn, Charles A., Flores, Gustavo E. (2002): Two New Species Of Asidopsis Casey From Arizona And Chihuahua, Mexico (Coleoptera: Tenebrionidae: Asidini). The Coleopterists Bulletin 56 (2): 285-290, DOI: 10.1649/0010-065x(2002)056[0285:tnsoac]2.0.co;2
AA504E5FAC264B3AFEE24C08FBFD6931.taxon	discussion	Discussion. Asidopsis humeralis even more closely resembles A. macra (Horn) than does A. olsoni. In addition to the general body configuration, some specimens of A. macra have a suggestion of the expanded humeral angles of the elytra, but never as abruptely pronounced as in A. humeralis. In A. humeralis, the elytra are shiny and distinctly punctate and the disc of the pronotum is minutely and sparsely punctate; in A. macra the elytra are dull and impunctate and the disc of the pronotum is more coarsely and densely punctate.	en	Triplehorn, Charles A., Flores, Gustavo E.
