Cyclocephala saltini Ratcliffe , new species

( Figs. 37–39 )

Type Material. Holotype male, labeled ‘‘ PERU: Huanuco, Chinchao , 1,800 m.

III-2006.’’ Allotype female, labeled ‘‘ PERU, Carpish, 20 km E. Acomayo, Dept. Huanuco, Oct 1946.’’ One male paratype with same data as holotype. Two male paratypes labeled ‘‘ PERU, Carpish, 20 km E. Acomayo, Dept. Huanuco, Oct 1946.’’

Holotype, allotype, and one paratype deposited at the University of Nebraska State Museum, Lincoln, NE. One paratype deposited in the U. S. National Museum, Washington, D. C., and one paratype placed in the Brett C. Ratcliffe Collection (Lincoln, NE) .

Holotype. Male. Length 18.7 mm; width across humeri 9.4 mm. Color black except for dark testaceous elytra, shining. Head: Frons with punctures moderate in density and size. Frontoclypeal suture biarcuate, distinctly impressed. Clypeus densely rugopunctate, punctures slightly larger than those on frons; apex broad, weakly emarginate at middle, slightly reflexed, with slender marginal bead. Interocular width equals 2.5 transverse eye diameters. Antenna 10-segmented, club subequal in length to segments 2–7. Pronotum: Surface weakly shagreened, sparsely punctate; punctures small on disc, becoming moderate in size on sides. Base lacking marginal bead. Posterior angles broadly rounded. Elytra: Surface finely shagreened, punctate; punctures moderate to moderately large, dense; double rows of punctate striae visible. Pygidium: Surface finely shagreened, punctures moderate in size and density, setigerous; setae moderately dense, long, tawny. In lateral view, surface convex, more so on apical half. Legs: Protibia tridentate, basal tooth small, strongly removed from apical 2 teeth. Protarsus strongly enlarged; tarsomeres 2–4 each slightly larger than preceding; 5th curved, subequal in length to tarsomeres 1–4, nearly flat on ventral surface; median claw enlarged, strongly bent, apex narrowly split into large and small rami (small ramus broken off on each claw). Metatarsus subequal in length to metatibia. Venter: Mentum, meso- and metasternites with dense, long, tawny setae. 240 Prosternal process long, columnar, apex expanded, transversely oval, with transverse, raised ‘‘button’’ on anterior half. Parameres: Figs. 38–39 .

Allotype. Female. Length 19.4 mm; width across humeri 10.8 mm. As holotype except in the following respects: Color testaceous except for black frons and reddish brown tarsi. Elytra: In ventral view, epipleuron gradually tapered at level of sternite 1; lateral margin just above this swollen into elongate flange. Pygidium: Setae sparse, short. In lateral view, surface nearly flat. Legs: Protarsus not enlarged.

Variation. Males (3 paratypes). Length 19.2–19.6 mm; width across humeri 9.7–10.0 mm. Two paratypes with black head, pronotum, and scutellum as in holotype, one paratype testaceous with black frons as in allotype. Otherwise, the paratypes do not differ significantly from the holotype. The interocular width equals 2.1 transverse eye diameters in two paratypes and 2.5 in another. One Carpish specimen has the apices of the parameres missing.

Etymology. This species is named in honor of Jochen-P. Saltin (Niedernhausen/ Taunus, Germany), who generously donated the Chinchao specimens for study.

Distribution. Cyclocephala saltini is known only from Chinchao and Carpish, both just to the northeast of the city of Huánuco in Huánuco province on the east side of the Andes in northern Peru.

Diagnosis. Cyclocephala saltini is distinctive because of the combination of its relatively broad shape and depressed body form, setose venter, coloration, and form of the male parameres.
