Nearns, Eugenio H., 2019, A new genus and species of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) from Ecuador, with notes on additional taxa, Insecta Mundi 701 (701), pp. 1-7 : 2-4

Velozideres buntyni Nearns , sp. nov.

( Fig. 1 a−d)

Description. Male. Length 10.5 mm (measured from vertex to elytral apices), width 4.0 mm (measured across humeri). Habitus as in Fig. 1a . Integument dark-brown to almost black, with white, gray, ochraceous, testaceous, and dark-brown pubescence.

Head. Frons about 3.5 times width of lower eye lobes. Eyes with narrowest area connecting upper and lower eye lobes about 3 ommatidia wide. Genae about 1/2 as tall as lower eye lobes. Antennae surpassing elytral apices by 5 antennomeres. Scape and antennomeres II–III with dense, recumbent pubescens, becoming sparser on antennomeres IV–XI; antennomeres III–XI with apical 1/3 distinctly darker. Antennal formula based on length of antennomere III: scape = 0.71; II = 0.19; IV = 0.84; V = 0.7; VI = 0.62; VII = 0.6; VIII = 0.58; IX = 0.62; X = 0.61; XI = 0.69.

Thorax. Pronotum about 1.5 times as wide as long; disk densely pubescent, with glabrous, subcircular patch behind center as wide as about 9 ommatidia. Apex of prosternal process subtriangular. Mesoster- nal process about 2/3 as wide as mesocoxal cavity. Scutellum transverse, subtruncate rounded. Elytra. Slightly more than 2 times as long as width at humeri, about 3.7 times as long as pronotal length, about 1.2 times broader basally than pronotum at its widest (at tubercles); lateral margins slightly attenuate, gradually rounded to apices at apical 1/4; disk densely pubescent, with scattered, moderately-deep punctation; humeri prominent, tubercle glabrous. Legs. Short; procoxae large, globose; femora robust; metafemora clavate apically; tibiae slightly expanded apically; tarsomere V about as long as I–IV combined.

Abdomen. Fifth abdominal ventrite slightly longer than IV.

Female. Length 11.5 mm (measured from vertex to elytral apices), width 4.3 mm (measured across humeri). Similar to male except antennae slightly longer than body; antennomeres IV–XI decreasing in length compared to III; ventrite V with a median triangular impression, about 2 times longer than IV.

Etymology. This species is named for my good friend and old Navy buddy, Dr. Larry Ross “Randy” Buntyn, Jr. (Ocean Springs, Mississippi, USA), for his friendship and generosity. The epithet is a noun in the genitive case.

Material examined. Holotype, ♂, ECUADOR: Manabi Prov., vic. Montecristi , 01.01534°S, 080.68195°W, 355 m, 17–26 Feb 2006, F. T. Hovore, I. Swift, coll. ( CASC) ; Allotype ♀, same data as holotype ( CASC) .

Remarks. The only two known specimens of this new species were collected together in Montecristi, Ecuador, “beaten from dead limbs of a Fabaceae shrub” (I. Swift, pers. comm.).
