Aphotaenius cambeforti Chalumeau 1983: 2–3, fig. 1, 5; Stebnicka 2009: 39–40, fig. 54.

Haroldiataenius cambeforti Chalumeau; Chalumeau 1983: 1, fig. 1; 3, fig. 5 (lapsus calami).

Diagnosis. Length 2.5–3.1 mm (Figs. 14–16). This species is distinguished by the head with a band of coarse punctures posteriorly (Fig. 10), clypeal margin thin and rounded on each side (lacking teeth), epipharynx with projecting tylus (Fig. 17), pronotal punctures evenly distributed, pronotal posterior margin evenly rounded (not lobe-like), metaventrite finely punctate, elytra with evenly convex intervals, and the parameres thick to broadly truncate apex (Figs. 18–19). It is known from Bolivia (Santa Cruz).

Type. BOLIVIA: San Miguel août 1977, CAMBEFORT; Sta-Cruz/Sierra, 63°34W 17°S (Chalumeau 1983) . Deposited in IREC (Chalumeau 1983), not examined.

Material Examined. (n = 35). BOLIVIA: Santa Cruz: 4-5 km N Achira, Road to Floripondo, S18° 090, W63° 470, 6350 ft. [1,935 m], 15-IX-2012, P. Skelley & C. Hamel, MV+UV light (1 FSCA); 4- 6 km SSE Buena Vista, F & F Hotel, 3-8-X-2004, Wappes & Morris (2 FSCA); same data, 19-22-X-2004 (2 MNKM); Buena Vista, F & F Hotel, 27-31- X-2002, Morris & Wappes (1 FSCA); same data, 7-10-X-2004 (2 FSCA); 3.7 km SSE Buena Vista, Hotel Flora & Fauna, 430 m, 5-15-XI-2001, M. C. Thomas and B. K. Dozier, tropical transition forest, BLT (2 FSCA); same locality, S17° 290, W63° 390, 10-IX-2012, P. Skelley, C. Hamel, cow dung (2 CMNC, 5 FSCA, 2 NHML, 1 TAMU); El Cairo, 5 km W Buena Vista, 16-18-X-2004, J. E. Eger, UV light (1 FSCA); Potrerillos del Guenda, 40 km NW Santa Cruz de la Sierra, 350-400 m, S17° 400, W63°27’, 7-9-IX-2012, P. Skelley, J. Wappes, 12w UV light trap (2 FSCA); same data, 22-24-IX-2012 (2 CEMT, 2 CMNC, 6 FSCA, 2 NMNH).

Remarks. Specimens were collected in cow dung and at light. A specimen from high elevation near Achira has the anterior clypeal margin thicker than those from the Santa Cruz de la Sierra region. In all other characters studied, it appears to be A. cambeforti, and for now we consider it to be that species. Additional material may shed light on this variation.
