Neocherentes dilloniorum Tippmann, 1960: 156

(Fig. 1 a−d, 4 a, d)

Redescription. Male. Length 11.5–9.0 mm (measured from vertex to elytral apices), width 4.4–4.0 mm (measured across humeri). Habitus as in Fig. 1a. General form elongate-oblong, moderately sized. Integument dark-brown to almost black, with white, gray, ochraceous, testaceous, and dark-brown pubescence; elytra with distinct pattern formed by curved and sinuate stripes of contrasting colors, forming almost an “X” shape extending from humeri to apices; mesosternum and abdominal sternites with similar stripes and colors.

Head. Frons subquadrate, about 4 times width of lower eye lobes. Eyes with lower lobes moderately sized, narrow, elongate; narrowest area connecting upper and lower eye lobes about 2 ommatidia wide. Genae elongate, about 1/2 as tall as lower eye lobes. Antennae distinctly longer than body, surpassing elytral apices by 5 antennomeres; antennal tubercles prominent, widely separated; tubercles armed at apex with short, blunt horn; scape clavate; antennomere III slightly sinuate. Antennal formula based on antennomere III: scape = 0.63; II = 0.18; IV = 0.87; V = 0.62; VI = 0.52; VII = 0.44; VIII = 0.37; IX = 0.36; X = 0.37; XI = 0.38.

Thorax. Pronotum roughly cylindrical, transverse, about 1.25 times as wide as long; disk densely pubescent, with two large, subround tumescences, one on each side of midline, each tumescence depressed obliquely by shallow furrow; each side of disk with short, glabrous line extending obliquely from base to about basal 1/3. Mesosternal process about 2/3 as wide as mesocoxal cavity, medially flat, emarginate apically. Scutellum transverse, apex rounded. Elytra. Slightly more than 2 times as long as width at humeri, about 3.7 times as long as pronotal length, about 1.5 times broader basally than pronotum at its widest (at base); lateral margins slightly attenuate, gradually rounded to apices at apical 1/3, apices jointly rounded; basal 1/2 with moderately dense, moderately deep punctation; humeri prominent, anterior margin arcuate. Legs. Short; femora robust; metafemora clavate apically; tibiae slightly expanded apically; metafemora about 1/3 as long as elytra; tarsomere V about as long as I–IV combined. Procoxae large, globose; apex of prosternal process subtriangular.

Abdomen. Fifth abdominal ventrite about 1.25 times longer than IV.

Female. Length 13.0−9.0 mm (measured from vertex to elytral apices), width 5.3– 3.7 mm (measured across humeri). Similar to male except antennae slightly longer than body; antennomeres X and XI decreasing in length compared to IX; basal 1/3 of profemora not transversely rugose; ventrite V with a median triangular impression.

Diagnosis and remarks. Neocherentes dilloniorum can be separated from its congeners by the following combination of characters: apical 1/3 of elytra with punctation, mesosternal process medially flat, and mesosternum and abdominal sternites with distinct striped pattern similar to dorsal surface (Fig. 4a, d). This species is known from a total of eight specimens (2 males, 6 females). All known specimens of this species were collected in Peru and Bolivia (Fig. 5) at relatively high elevation (1,400 −2,558 m). Monné (2005) was the first to report this species from Bolivia, followed by Wappes et al. (2006). Lingafelter et al. (2014) provided color photographs of the holotype specimen.
