Cenophengus villae Zaragoza-Caballero, 1984: 198.

Type locality.

Veracruz, Mexico.

Type material examined.

Holotype ♂: Mexico: "Veracruz, Metlac, / VI. 76 /900 m.a.s.l. / S. Zaragoza / Col. Noc." | CNIN.

Remarks.

Cenophengus villae is sister to C. brunneus ( Vega-Badillo et al. 2021b), but can be distinguished by the interocular distance: in C. villae , it is 4 times eye width, whereas in C. brunneus , it is 3.5 times longer. Additionally, in C. villae , the pronotal disc has a longitudinal carina, whereas in C. brunneus , the disc is without a longitudinal carina.

Diagnosis.

Body dark brown, integument chagreened, antennae less than twice the length of the pronotum, antennal rami 1.5 times the respective antennomere and each elytron 4.3 times as long as wide.

Redescription.

Male. Body length 4.20 mm, maximum body width 0.51 mm (pronotum). Body dark brown, except for legs yellowish (Fig. 30A ). Head. Wider (0.65 mm) than long (0.50 mm) (Fig. 30B ), at eye level, less wide than the pronotum, integument chagreened, punctures twice as long as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a brown seta; interantennal distance (0.05 mm) less than the length of antennomere 1 (0.13 mm); eyes 1/2 as long as head in lateral view, longer (0.28 mm) than wide (0.15 mm); interocular distance (0.70 mm) 4 times eye width; antennae short (1.50 mm) less than twice the length of the pronotum; antennomere 1 (0.13 mm) as long as the next two combined, antennomere 3 cup-shaped, 4 (0.11 mm) shorter than following antennomeres, 5 to 11 about equal in length (0.15 mm), 12 (terminal) (0.20 mm), antennal rami lanceolate in lateral view, 1.5 times the respective antennomere; terminal maxillary palpomere robust, securiform (0.40 mm), as long as the preceding three combined; terminal labial palpomere spindle-shaped (0.06 mm), 3 times as long as preceding one (0.02 mm). Thorax. Pronotum longer (0.70 mm) than wide (0.51 mm) (Fig. 30C ); integument chagreened, punctures twice as long as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a brown seta, disc convex, with a longitudinal carina in posterior portion of pronotum strongly visible, with a length that does not reach the median length of the pronotum, posterior margin curved, sides almost straight, anterior and posterior angles rounded; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 4.3 times as long (1.64 mm) as wide (0.38 mm), convex, without longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length 5 times less than the length of MP1+2, radial cell closed, r3 vein present, r4 vein reduced (not reaching the RP or the radial cell, those of the anterior anal and posterior anal sectors, evident (Fig. 30D ). Legs: tarsomeres 1 and 2 of pro- and mesothoracic legs with a similar length, tarsomere 1 of metathoracic legs is longer than 2. Abdomen. Integument shiny, punctured, with long dense setae, sternite 7 with margin sinuate, sternite 8 with margin notched; aedeagus of the holotype lost.

Female and immatures.

Unknown.

Distribution.

Mexico: Veracruz (Fig. 19 ).
