(Fig. 32–38)
Description. Male (Fig. 32–36). Integument mostly dark brown; frons gradually dark reddish brown toward clypeus; gulamentum partially dark reddish brown centrally; anteclypeus blackish posteriorly, testaceous anteriorly; labrum mostly dark reddish brown; mouthparts mostly yellowish brown; coxae, trochanters and base of femora dark reddish brown.
Head. Frons coarsely, abundantly punctate; with abundant yellowish-white pubescence not obscuring integument, with long, erect brownish setae interspersed. Vertex with sculpturing as on frons anteriorly, slightly, gradually denser toward prothoracic margin; with wide, dense yellowish-white band centrally, gradually more light yellowish brown toward prothoracic margin; sides almost glabrous close to upper eye lobes, with sparse brown pubescence toward prothorax (denser posteriorly); with long, erect, sparse setae interspersed, brownish anteriorly, mostly yellowish brown posterocentrally. Area behind upper eye lobes coarsely, abundantly punctate; with sparse brown pubescence, less defined close to eye; with a few long, erect brownish setae interspersed. Area behind lower eye lobes coarsely, abundantly punctate; with light yellowish-brown pubescence toward upper eye lobe not obscuring integument, denser, yellowish-white close to eye toward genal area, distinctly sparser close to prothoracic margin; with long, erect sparse yellowish-white setae interspersed. Gena coarsely, sparsely punctate toward ventral area, smooth toward dorsal area and apex; with sparse yellowish-white pubescence ventrally, nearly glabrous on smooth area toward dorsal region, apex glabrous, with long, erect yellowish-white setae interspersed on punctate area. Antennal tubercles with sculpturing as on frons basally, gradually finer, sparser toward apex; with brown pubescence not obscuring integument anteriorly, more yellowish-brown posteriorly, with long, erect dark setae interspersed. Distance between upper eye lobes 0.50 times length of scape; in frontal view, distance between lower eye lobes 1.08 times length of scape. Antennae 1.75 times elytral length, reaching elytral apex at base of antennomere VIII. Scape coarsely, abundantly punctate; with brownish pubescence not obscuring integument, more yellowish-brown basally, punctures sparser ventrally, with long, erect brown setae interspersed. Antennomeres with long, erect brown setae interspersed, longer ventrally, especially on III–VI, gradually shorter and sparser toward XI. Antennal formula (ratio) based on length of antennomere III: scape = 0.67; pedicel = 0.21; IV = 1.02; V = 0.65; VI = 0.57; VII = 0.48; VIII = 0.38; IX = 0.32; X = 0.27; XI = 0.35.
Thorax. Prothorax transverse (including lateral tubercles); sides with large tubercle centrally. Pronotum coarsely, abundantly punctate; with dense yellowish-white pubescent band centrally (slightly yellower about middle), distinctly narrowed after tubercle on posterior third; sides with dense yellowish-brown pubescence; with long, erect, sparse yellowish-white setae interspersed. Sides of prothorax coarsely, abundantly punctate; with dense yellowish-brown pubescence close to pronotum, distinctly sparser on wide area close to prosternum; with sparse, long, erect, yellowish-brown setae interspersed. Prosternum coarsely, sparsely punctate; with distinctly sparse yellowish-white pubescence and a few long, erect setae of same color. Ventral surface of meso- and metathorax coarsely, abundantly punctate, especially laterally; with yellowish-white pubescence not obscuring integument, slightly denser laterally. Scutellum with white pubescence partially obscuring integument. Elytra. Coarsely, abundantly punctate (punctures slightly finer and sparser toward apex); with abundant grayish-white pubescence not obscur- ing integument, with long, erect, abundant brown setae interspersed throughout. Legs. Femora with yellowish-white pubescence not obscuring integument, with long, erect setae of same color interspersed. Tibiae with yellowish-white setae not obscuring integument basally, with long, erect setae of same color interspersed, gradually bristly, yellowish-brown toward apex, especially on meso- and metatibiae.
Abdomen. Coarsely, sparsely punctate laterally, finer and sparser centrally; with abundant yellowishwhite pubescence not obscuring integument, with long, erect setae of same color interspersed.
Female (Fig. 37–38). Antennae slightly shorter; abdominal ventrite V distinctly more convex.
Dimensions (mm), holotype male / paratypes male / paratypes female. Total length, 4.20/4.10–4.80/4.45– 5.35; prothoracic length, 0.85/0.75–0.90/0.80–0.90; anterior prothoracic width, 0.80/0.80–0.90/0.80–0.95; posterior prothoracic width, 0.80/0.80–0.95/0.80–1.00; maximum prothoracic width, 1.05/0.95–1.10/0.95– 1.20; humeral width, 1.15/1.15–1.35/1.20–1.45; elytral length, 2.85/2.95–3.35/3.20–3.65.
Type material. Holotype male from MEXICO, Hidalgo: 3 miles N Tlanchinol, 8.V.1983, C.W. and L. O’Brien col. (FSCA, formerly ACMT). Paratypes – 1 female, same data as holotype (ACMT); 3 males (1, MZSP; 2, ACMT), 1 female (ACMT), same data as holotype except 2.4 miles N Tlanchinol, 8–9.V.1983.
Remarks. Eupogonius tlanchinolensis sp. nov. is similar to E. obrienorum Galileo and Santos-Silva, 2017, but differs as follows: upper eye lobes proportionally narrower (Fig. 32); vertex with wide central pubescent band contrasting with remaining pubescence of the vertex (Fig. 32, 37); femora mostly dark brown; prothorax with distinct lateral tubercle (Fig. 36). In E. obrienorum (Fig. 39–40), the upper eye lobes are proportionally larger, vertex without central pubescent band contrasting with remaining pubescence, femora mostly reddish brown, and prothorax without lateral tubercle.
Etymology. Named for the city, Tlanchinol, in the vicinity of which the type series of this species was collected.
