Hoplopygothrix boliviensis Ratcliffe , new species ( Figs. 1–5 , 9 )

Type Material. Holotype male labeled “ Bolivia: Santa Cruz, 5km S. Pampa Grande, Oleoducto Road, 18-20/XI/03, Morris, Nearns, Wappes” and with my red holotype label . Holotype deposited at the University of Nebraska State Museum (Lincoln, NE) .

Holotype. Male. Length 13.4 mm; width 7.7 mm. Head: Color black, velutinous, with 2 parallel, cream-colored vittae extending from occiput mesad of each eye to clypeus where vittae coalesce to cover most of clypeus. Surface sparsely punctate on vittae, densely punctate between vittae; punctures black, moderately large, setigerous; setae short to mostly long, black to dark brown, less dense on clypeus; eye canthus with several long, stout, black setae. Clypeus at apex strongly reflexed, lacking marginal bead, emarginate at center with broadly rounded anterior angles. Interocular width equals 5.0 transverse eye diameters. Antenna 10-segmented, club subequal in length to segments 2-7. Pronotum: Color black, velutinous, with 2 short, parallel, cream-colored vittae at apex and with irregular, cream-colored band on lateral margins. Surface punctate on apical half and sides, sparsely punctate on basal half of disc; punctures small to moderate in size on disc, becoming larger on lateral margins and anterior half; punctures round to crescent-shaped, often confluent near anterior angles, setigerous; setae moderately dense, becoming denser in anterior half, long, dark brown. Lateral margin with distinct bead. Epimeron with color and surface similar to that of lateral margin of pronotum. Scutellum at apex with small tuft of dark brown setae. Elytra: Color mostly black, suffused with dark reddish brown, velutinous, with cream-colored, transverse spots just behind humerus, middle next to suture, lateral margin behind middle, and on apical umbone ( Fig. 1 ). Surface on disc with indistinct rows of punctures; punctures small to moderate, mostly crescent-shaped, only some punctures setigerous; setae minute to short, dark reddish brown. Apex with dense, moderately large, crescent-shaped punctures. Apical umbone prominent. Apices at suture subquadrately obtuse. Lateral margin with prominent bead. Pygidium: Color black, shiny, with cream-colored spot in angles (moderately large) and at center base and apex (both small). Surface concentrically rugulose, setigerous; setae moderate in density, short, dark brown. In lateral view, surface weakly convex. Venter: Color black ( Fig. 2 ), shiny, abdominal ster- nites 1-5 with small, cream-colored patch on posterolateral edge; last sternite with transverse, cream-colored band at apex; metacoxa creamcolored on lateral edge. Thoracic sternites with dense, long, dark reddish brown to black setae. Mesometasternal process nearly flat, short (not reaching procoxae), apex shiny and narrowly rounded. Abdominal sternites each with several large punctures on lateral thirds. Sternites 1-4 with distinct, longitudinal sulcus. Last sternite setigerously punctate on lateral corners, setae black, moderate in length. Legs: Femur and tibia black, shiny, overlain with extensive areas of cream color interspersed with large, black punctures. Protibia with 1 lateral tooth at apex. Metatibia with 2 articulated, apical spurs with acute apices. Parameres: Form not noticeably constricted in caudal view and apex entire ( Figs. 3–5 ).

Distribution ( Fig. 9 ). 1 specimen examined. BOLIVIA: Santa Cruz (1): Pampa Grande (5 km S).

Temporal Distribution. November (1).

Diagnosis. Hoplopygothrix boliviensis differs from H. atropurpurea by the strongly reflexed clypeus (present in H. boliviensis , absent in H. atropurpurea ), bead on the apical margin of

THE COLEOPTERISTS BULLETIN 65(1), 2011 65

the clypeus (absent in H. boliviensis , present in H. atropurpurea ), absence of a distinctly tawny tuft of setae at the apex of the scutellum (present in H. atropurpurea ), convex pygidium (flat in H. atropurpurea ), presence of cream-colored vittae or spots on the dorsum and venter (venter only in H. atropurpurea ), and form of the male genitalia ( Figs. 3–8 ). The genitalia of H. boliviensis have a proportionally longer basal piece, the parameres are not noticeably constricted laterally as in H. atropurpurea , and the apex lacks the distinctive spine seen in H. atropurpurea . The female of H. boliviensis remains unknown.

Biology. A single specimen is insufficient to determine the extent of the geographic or temporal distributions. As with many captures of singletons, nothing is known of the biology of this species.
