Cenophengus sonoraensis Zaragoza-Caballero 2008: 155.

Type locality.

Sonora, Mexico.

Type material examined.

Holotype ♂: "MEXICO: Sonora, 36.6 / km SE Tecoripa, La / Barranca, 28°34'40.1"N, / 109° 39' 40.1"O. Alt. 562 m. / TL 1 16-08-2004 / Col. S. Zaragoza" | CNIN.

Remarks.

Cenophengus sonoraensis is sister to C. pallidus ( Vega-Badillo et al. 2021b), but can be distinguished by the colour of the body and the interocular distance. In C. sonoraensis , it has a pale brown body, whereas in C. pallidus , it is yellow. The interocular distance is twice as long as eye width in C. sonoraensis , in C. pallidus , it is 1.5 longer than eye width. Additionally, in C. sonoraensis , disc weakly elevated dorsally, forming a small depression in the basal part of each side, whereas in C. pallidus , it has a longitudinal carina.

Diagnosis.

Body pale brown, integument chagreened, head wider than the pronotum, antennae less than twice the length of the pronotum, antennal rami twice as long as the respective antennomere and each elytron 4.1 times as long as wide.

Redescription.

Male. Body length 4.20 mm, maximum body width 0.55 mm (pronotum). Body pale brown, except for head dark brown (Fig. 27A, B View Figure 27 ). Head. Wider (0.69) than long (0.35 mm) (Fig. 27C View Figure 27 ), at eye level, wider than the pronotum, integument chagreened, punctures as long as eye facets and separated by approximately 2 punctured diameters, each puncture bearing a yellow-brown seta; interantennal distance (0.07 mm) less than the length of antennomere 1 (0.15 mm); eyes 3/4 as long as head in lateral view, longer (0.30 mm) than wide (0.20 mm); interocular distance (0.38 mm) twice as long as eye width; antennae short (1.20 mm) less than twice the length of the pronotum; antennomere 1 (0.15 mm) is longer than the next two combined, antennomere 3 cup-shaped, 4 (0.10 mm) shorter than following antennomeres, 5 to 11 about equal in length (0.11 mm), 12 (terminal) (0.12 mm), antennal rami lanceolate in lateral view, twice as long as the respective antennomere; terminal maxillary palpomere robust, securiform (0.25 mm), as long as the preceding three combined (0.25 mm); terminal labial palpomere spindle-shaped (0.10 mm), 3 times as long as preceding one (0.03 mm). Thorax. Pronotum longer (1.40 mm) than wide (1.0 mm) (Fig. 27D View Figure 27 ); integument chagreened, punctures as long as eye facets and separated by approximately 2 punctured diameters, each puncture bearing a yellow-brown seta, disc convex, weakly elevated dorsally forming a small depression in the basal part of each side, sides almost straight, anterior and posterior angles rounded; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 4.1 times as long (1.40 mm) as wide (0.34 mm), convex, without longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length 3.5 times less than the length of MP1+2, radial cell closed, r3 vein absent, r4 vein reduced (not reaching the RP and the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 27E View Figure 27 ). Legs: tarsomere 1 of pro-, meso- and metathoracic legs is longer than 2. Abdomen. Integument shiny, punctured, with long dense setae, sternite 7 with margin sinuate, last sternite with margin notched; aedeagus of the holotype lost.
