(Fig. 59–65)
Description. Male (Fig. 59–63). Integument mostly black; antennae gradually dark brown toward distal segments; elytra with large, irregular reddish-brown area centrally, from about basal third to near apex (slightly, to not visible, depending on light intensity). General pubescence yellowish-white (whiter depending on light intensity), slightly yellower on pronotum.
Head. Frons finely, abundantly punctate; pubescence not obscuring integument, slightly denser laterally and close to clypeus; with abundant, long, erect brown setae, and a few long, erect yellowish setae. Vertex with sculpturing as on frons; with dense pubescence close to eyes, sparse centrally; with abundant, long, erect, brown setae. Area behind eyes with sculpturing as on frons close to eye, smooth toward prothoracic margin; with dense pubescence close to upper eye lobe, slightly sparser behind lower eye lobe, and covering wider area toward gena; area close to prothorax glabrous; with a few long, erect brown setae close to upper eye lobe, and abundant, long, erect, yellowish setae close to lower eye lobe. Genae finely, sparsely punctate, more so toward clypeus; pubescence partially obscuring integument, apex glabrous, with a few long, erect yellowish setae interspersed. Antenal tubercles with sculpturing, both anteriorly and posteriorly as on frons, smooth centrally, with long, erect brown setae interspersed on punctate area. Distance between upper eye lobes 0.53 times length of scape; in frontal view, distance between lower eye lobes 0.95 times length of scape. Antennae (only holotype measured) 1.7 times elytral length, reaching elytral apex at middle of antennomere IX. Scape with white pubescence not obscuring integument, with long, erect dark setae dorsally and laterally, and long, erect yellowish setae ventrally. Antennomeres III–IV with white pubescence not obscuring integument (more yellowish-brown dorsally on posterior area of IV), with long, erect, abundant dark setae interspersed (longer ventrally). Antennomeres V–X with brown pubescence, with short, decumbent yellowish-brown setae interspersed, and long, erect dark setae ventrally, and on apex of dorsal surface (setae gradually shorter, sparser toward X). Antennomere XI with brown pubescence, with short, decumbent yellowish-brown setae interspersed, and dense yellowish-white setae at apex. Antennal formula (ratio) based on length of antennomere III: scape = 0.67; pedicel = 0.15; IV = 0.89; V = 0.42; VI = 0.38; VII = 0.38; VIII = 0.33; IX = 0.31; X = 0.27; XI = 0.29.
Thorax. Prothorax wider than long (including lateral tubercles); sides with large, conical tubercle at middle (apex blunt). Pronotum coarsely, abundantly punctate, except smooth, elongate area on center of posterior half; pubescence abundant laterally (this area distinctly widened anteriorly), not obscuring integument on anterior half, denser on posterior half, remaining surface with sparse pubescence, except pubescence more abundant on center of posterior quarter; with long, erect dark setae on wide central area, mostly yellowish laterally. Sides of prothorax with sculpturing as on pronotum; pubescence abundant, but not obscuring integument, with long, erect yellowish setae interspersed. Prosternum on posterior 3/4 coarsely, sparsely punctate, distinctly sparser on anterior quarter; pubescence not obscuring integument, denser on sides of posterior 3/4, sparser on anterior quarter; with long, erect yellowish setae interspersed. Ventral surface of meso- and metathorax with pubescence partially obscuring integument laterally, distinctly sparser on center of metaventrite, with long, erect yellowish setae interspersed; metanepisternum and sides of metaventrite coarsely, abundantly punctate. Scutellum with dense pubescence, especially laterally. Elytra. Coarsely, abundantly punctate on basal third, gradually finer, sparser toward apex; pubescence irregularly dense on some areas, sparser or nearly glabrous in others, with long, erect, both dark and yellowish setae interspersed. Legs. Femora with abundant pubescence, but not obscuring integument, with abundant, long, erect yellowish setae. Tibiae with pubescence not obscuring integument, with abundant, long, erect yellowish setae (yellower toward apex of ventral surface), except dorsal surface of posterior half of mesotibiae with dense yellowish-brown pubescence.
Abdomen. Ventrites with abundant pubescence not obscuring integument, and dense fringe of yellowishbrown setae on posterior margin of ventrite I, less so on other ventrites; with long, erect yellowish setae interspersed, distinctly sparser centrally.
Female (Fig. 64–65). Antennae shorter than in male, 1.35 times elytral length, almost reaching elytral apex.
Variation. Antennomeres V–XI with white pubescence not obscuring integument.
Dimensions (mm), holotype male/ paratype male/ paratype female. Total length, 8.80/10.95/8.25; prothoracic length, 2.00/1.95/1.60; anterior prothoracic width, 1.75/1.70/1.65; posterior prothoracic width, 1.80/1.70/1.75; maximum prothoracic width, 2.40/2.25/2.15; humeral width, 2.70/2.80/2.60; elytral length, 5.70/6.00/5.85.
Type material. Holotype male from MEXICO, Jalisco: 7 km N Malacque, 16–19.VII.1990, J.E. Wappes col. (FSCA, formerly ACMT). Paratypes – MEXICO, Colima: Road to El Terrero (3,000–4,000 ft.), 1 male, 1 female, 4.X.1992, J.E. Wappes col. (male, MZSP, female, ACMT).
Remarks. Eupogonius nascimentoi sp. nov. is similar to E. guerrerensis sp. nov. but differs by the distance between upper eye lobes distinctly wider than maximum diameter of the scape (about equal to maximum width of the diameter of the scape in E. guerrerensis. It differs from E. boteroi sp. nov. by the shorter antennae, almost reaching elytral apex (surpassing elytral apex in females of E. boteroi) and elytra without white pubescence (present in E. boteroi). Eupogonius nascimentoi especially differs from E. comus by the fusiform metafemora (Fig. 63), (pedunculate-clavate in E. comus (Fig. 66)).
Etymology. This species is named to recognize Francisco Eriberto de Lima Nascimento (MZSP) for his friendship, and contribution to the knowledge of Neotropical Cerambycidae.
