Type locality. Bolivia, Cochabamba Department, Estación Biológica Sacta.

Description. Holotype male. Length 6.7 mm; width 3.5 mm. Color: Head, pronotum and elytra black to piceous. Venter and legs piceous to reddish brown. Head: Frons impunctate at base, becoming rugopunctate apically. Frontoclypeal suture effaced. Clypeus rugopunctate; anterior margin with median tubercle. Pronotum: Surface punctate; punctures moderate to dense, moderate to large, occasionally umbilicate, concentrated on sides. Basal margin with bead and complete row of punctures. Disc with longitudinally subovate, punctate fovea; punctures dense, small. Anterior margin with median boss. Elytra: Punctures of striae elongate or vermiform, occasionally V-shaped. Lateral margin adjacent to humerus with 6 setose crenulations. Legs: Protibia with worn apical denticle. Genitalia: Fig. 63-64 .

Allotype. Female. Length 7.5 mm; width 4.4 mm. Allotype similar to holotype except in the following respects: Head: Anterior margin of clypeus without tubercle, with marginal bead. Pronotum: Disc with punctate depression; punctures moderate to dense, moderate in size, transversely oval. Anterior margin of pronotum with median boss. Scutellum: Surface with one median, moderately sized puncture. Elytra: Stria 1 obsolete at base. Lateral margin adjacent to humerus with 5 (right) or 7 (left) setose crenulations. Legs: Protibia without apical denticle. Genitalia: Fig. 73-74 .

Paratypes. (Males = 2, females = 70) Length 6.0- 9.1 mm; width 3.2-5.0 mm. Paratypes differ from the primary types in the following respects: Male. Head: Anterior margin of clypeus with erect, slightly recurved horn (major) or tubercle (minor). Pronotum: Disc with subtriangular fovea (major) or longitudinally suboval fovea (minor); fovea with a raised into a rounded tumosity on each edge (major) or not (minor). Elytra: Striae 1 and/or 2 obsolete at base. Lateral margin adjacent to humerus with 5-8 setose crenulations. Legs: Protibial denticle not as worn. Females. Elytra: Striae 1 and 2 variably obsolete at base. Lateral margin adjacent to humerus with 4-8 setose crenulations. Genitalia: Accessory sclerite reduced ( Fig. 74 ) in some specimens.

Diagnosis. This species is easily distinguished from other species in the genus based on the form of the male genitalia ( Fig. 63-64 ) and the female gonocoxites ( Fig. 73-74 ). Males are similar to A. petrovi ( Fig. 61-62 ), but in A. teamscaraborum the median lobes are longer than the lateral lobes (they are subequal in length in A. petrovi ). In females, the superior and inferior plates are completely fused, which separates this species from the females of A. oreibates ( Fig. 70 ; the superior and inferior plates are not completely fused). The size of the accessory sclerites varies, and in some specimens the sclerites may appear to be completely absent ( Fig. 74 ).

Etymology. This species is named for the Team Scarab Lab at the University of Nebraska-Lincoln, and in honor of the lab’s past, present, and future members.

Distribution (Fig. 92). Bolivia and Peru. Seventy-three specimens examined from AMNH, CMNC, CNCI, FMNH, HAHC, MNHN, USNM, and UNSM. BOLIVIA (70): Cochabamba: Chapare (1); Est. Biol. Sacta (7); Hotel el Puenta (Villa Tunari) (12). La Paz: Corocio (Nor Yongas) (1).

Unknown: Chopare (1). PERU (3): Junín: Between San Ramon de Pangoa and Boca de Kiatari (45-55 km SE Satipo) (2). Madre de Dios: Rio Tambopata Res (30 air km SW Puerto Maldonado) (1).

Temporal Distribution. March (2), November (19), December (49).

Natural History. Specimens were collected between 300-440 m elevation, and from sandy areas at lights at dusk.
