(Fig. 45–50)
Description. Male (Fig. 45–48). Integument mostly dark brown; anterior half of anteclypeus testaceous; abundant, long, erect white setae more yellowish depending on light intensity.
Head. Frons coarsely, abundantly punctate; with yellowish-white pubescence partially obscuring integument, slightly yellower centrally toward vertex; with long, erect, abundant white setae throughout, and long, erect brown setae near eyes. Vertex with sculpturing as on frons between antennal tubercles and upper eye lobes, slightly finer, sparser toward prothoracic margin; with pale yellow pubescence partially obscuring integument, denser close to eyes, slightly sparser toward prothoracic margin; with long, erect, both white and brown setae interspersed. Area behind eyes coarsely, abundantly punctate; with pale yellow pubescence obscuring integument, with long, erect white setae interspersed, more abundant behind lower eye lobe. Gena finely, sparsely punctate distal area smooth; with white pubescence not obscuring integument toward clypeus, denser, pale yellow toward inferior area, except glabrous smooth area; with long, erect white setae interspersed. Antennal tubercles with punctures slightly finer than on frons; with yellowish-white pubescence not obscuring integument, with long, erect brown setae interspersed. Distance between upper eye lobes 0.42 times length of scape; in frontal view, distance between lower eye lobes 0.92 times length of scape. Antennae 1.5 to 1.65 times elytral length, reaching elytral apex about middle of antennomere IX. Scape coarsely, abundantly punctate; with white pubescence not obscuring integument, with long, erect, abundant, both white and dark setae interspersed. Antennomeres III–IV with sparse white pubescence, less so on distal third of IV, with long, erect, abundant dark setae interspersed (also with a few long, erect white setae), longer ventrally. Antennomeres V–IX with dark pubescence, interspersed with a few short, decumbent white setae, long, erect dark setae (distinctly longer ventrally), and long, erect white setae dorsally. Antennomeres X–XI with dark pubescence, with long, erect white setae interspersed throughout. Antennal formula (ratio) based on length of antennomere III: scape = 0.61; pedicel = 0.15; IV = 1.02; V = 0.47; VI = 0.44; VII = 0.43; VIII = 0.37; IX = 0.32; X = 0.29; XI = 0.31. Thorax. Prothorax slightly wider than long (including lateral tubercles); sides with distinct small conical tubercle at middle. Pronotum coarsely, abundantly punctate; with pale yellow pubescence, denser laterally, narrow longitudinal pubescent band centrally on anterior third, and slightly distinct Y-shaped pubescent band on center posterior half; remaining surface with slightly sparser pubescence; with long, erect, both dark and white setae interspersed (white setae more abundantly laterally). Sides of prothorax coarsely, abundantly punctate; with pale yellow pubescence partially obscuring integument, with long, erect white setae interspersed (shorter toward prosternum). Prosternum coarsely, moderately sparsely punctate (punctures sparser on anterior third); with sparse yellowish-white pubescence centrally, denser laterally, with long, erect setae of same color interspersed. Ventral surface of meso- and metathorax with pale yellow pubescence partially obscuring integument, slightly more yellowish-white toward central area, with long, erect setae of same color interspersed. Scutellum with dense yellowish-white pubescence. Elytra. Coarsely, abundantly punctate on basal third, gradually finer, slightly sparser toward apex; with pale yellow pubescence partially obscuring integument, sparser on triangular circum-scutellar area, except wide, irregular, longitudinal white pubescent band on center of dorsal surface, from near base to about middle, and irregular yellowish-white pubescent maculae on dorsal surface; with long, erect, abundant, both dark and white setae interspersed (white setae more abundant laterally). Legs. Femora with white pubescence not obscuring integument, with long, erect, both dark and white setae interspersed (dark setae sparser). Tibiae with sparse white pubescence, and long, erect, abundant white setae interspersed (with a few long, erect dark setae on distal area), except dorsal half of mesotibiae with yellowish, dense pubescence.
Abdomen. Ventrites with abundant yellowish-white pubescence not obscuring integument centrally, yellower, denser laterally, with long, erect yellowish setae interspersed (sides and posterior area of ventrite V also with long, erect dark setae).
Female (Fig. 49–50). White longitudinal band of elytra more distinct and longer (fragmented on posterior half). Antennae slightly shorter, 1.3–1.5 times elytral length, with its apex approximating elytral apex or slightly surpassing it.
Dimensions (mm), holotype male/ paratype female. Total length, 7.00/6.60; prothoracic length, 1.40/1.35; anterior prothoracic width, 1.30/1.25; posterior prothoracic width, 1.35/1.30; maximum prothoracic width, 1.65/1.55; humeral width, 2.00/1.85; elytral length, 5.00/4.65.
Type material. Holotype male from MEXICO, Sonora: 16 km SSE Nacozari de Garcia (Rancho La Zulema; 30°28′N / 109°56′W; 1687 m), 15.VII.2017, van Devender and Palting col. (ASUHIC, formerly ACMT). Paratype female, same data as holotype (MZSP); Rancho El Jaraza, 22.4 km N Narcozari de Garcia, El. 1595 meters, 30°57′56′′N 109°73′25′′W, 2 males, 2 females, 15.VII.2013, T. van Devender & J. Palting col. (ACMT).
Remarks. Eupogonius sonorensis sp. nov. is similar to E. arizonensis (see photograph of the holotype at Bezark 2019a) by the similar elytral pubescence but differs by the basal antennomeres proportionally shorter and a little stouter.
Etymology. This species was collected in the Sierra Juriquipa mountains by participants in “Greater Goods” Madrean Discovery Expeditions project to document the plant and animal diversity in the Sky Island mountain ranges in Sonora, Mexico, and was named “ sonorensis ” for the state of Sonora where it was collected.
