(Figures 8 a-d)

Description. Female. Length 11.0-14.0 mm (measured from vertex to elytral apices), width 4.5-6.0 mm (measured across humeri). Habitus as in Fig. 8b. General form elongate-ovate, moderate-sized. Integument ferrugineous to dark brown, with brown, white, and testaceous pubescence; pronotum with distinct longitudinal, testaceous vitta at center; scutellum testaceous; elytra densely speckled with white and testaceous pubescence.

Head with frons elongate, about 2.3 times width of one lower eye lobe (as in Fig. 8d). Eyes with lower lobes moderate-sized, oblong; narrowest area connecting upper and lower eye lobes about 3 ommatidia wide. Genae elongate, about as tall as lower eye lobes.

Antennae about as long as body; antennal tubercles prominent, moderately separated; tubercles not armed at apex; scape robust, gradually expanded to apex, slightly clavate; antennomeres III slightly curved. Antennal formula based on antennomere III: scape=0.78; II=0.12; III=1; IV=0.78; V=0.6; VI=0.53; VII=0.47; VIII=0.4; IX=0.37; X=0.34; XI=0.31.

Pronotum distinctly conical, wider at base, transverse, about 1.6 times as wide as long, sides nearly straight, slightly arcuate, without lateral protuberances (Fig. 8b); disk with three feebly elevated tubercles, sometimes absent; disk shallowly, sparsely punctate.

Scutellum transverse, apex rounded.

Elytra about 1.8 times as long as width at humeri (Fig. 8b), nearly 5 times as long as pronotal length, about 1.5 times broader basally than pronotum at widest (at base); lateral margins nearly straight, gradually rounded to apices at apical 1/3, apices individually rounded; base of each elytron with a feeble, broad gibbosity; basal 1/3 of elytra with dense punctation, surface somewhat coarsely, shallowly punctate; humeri prominent, anterior margin arcuate, angle with broad, obtuse tubercle.

Venter with procoxae large, globose, not uncate; narrowest area of prosternal process between procoxae about 1/5 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about as wide as mesocoxal cavity; mesosternal process deeply emarginate. Fifth abdominal sternite about twice as long as IV, apex emarginate

Legs moderate in length; femora robust; metafemora clavate apically; tibiae slightly expanded apically; metafemora about 1/3 as long as elytral; meso- and metatibiae lacking longitudinally depressed areas (present in male specimens).

Material Examined. Holotype, male (Fig. 8a, c), “ Ecuador: Napo Pr., 24 km E Atahualpa, 09-12 Sept 2004, F. T. Hovore, coll.” (CASC). Two paratypes: one male, same data as holotype (CASC); one male, “ Ecuador: Napo, Res. Ethnica Waorani, 1km S. Okone Gare Camp, Trans. Ent. 3 Oct. 1996, 220 m. 00º39’10”S 076 º 26’W, T. L. Erwin, et al.” (ENPC). Two specimens: one female, “Pérou, Tarapoto, Mai à Août 1886, M. de Mathan ” (ENPC); one female (Fig. 8b, d), “[Brazil] Sto. Paulo dOlivença, M. de Mathan, Mai 1883 ” (ENPC).

Diagnosis and Remarks. This species is distinguished from its congeners by the combination of the following characters: pronotum with longitudinal, testaceous vitta at center; elytra densely speckled with white and testaceous pubescence; and procoxae in males not uncate.
