Type locality.

San Luis Potosí, Mexico.

Type material.

Holotype ♂: "MEXICO: S.L.P., Mun. / Xilitla 15 mi. SW. / Xilitla, 1500 m., 20-III-1988/ R. E. Jones P. W. / Kovarik, Colls" "From the Michael / Ivie Collection" (TIP-COL) | CNIN.

Remarks.

Cenophengus gardunoi is morphologically similar to C. major , but can be distinguished by the integument and r3 vein. In C. gardunoi , the integument is chagreened, whereas in C. major , it is smooth; the r3 vein is absent in C. gardunoi , whereas in C. major , it is present.

Diagnosis.

This species can be distinguished by the chagreened integument, antennae long, more than twice the length of pronotum, antennal rami 3 times the respective antennomere and each elytron 4.4 times as long as wide, with two longitudinal costae and aedeagus with three teeth at the inner apex of paramere.

Description.

Male. Body length 16.0 mm; maximum body width 2.0 mm (pronotum). Body orange, except for the antennae, maxillary palpi, labial palpi, abdomen, hind wings and legs dark brown (Fig. 8A, B ). Head. Wider (1.5 mm) than long (0.72 mm) (Fig. 8C ), at eye level, less wide than the pronotum, integument chagreened, punctures twice as large as eye facets and separated by approximately 0.5 punctured diameters, each puncture bearing a yellow-orange seta; interantennal distance (0.15 mm) less than the length of antennomere 1 (0.45 mm); eyes 3/4 as long as head in lateral view, longer (0.60 mm) than wide (0.45 mm); interocular distance (0.80 mm) 1.7 times eye width; antennae long (4.50 mm) more than twice the length of pronotum; antennomere 1 (0.45 mm) longer than next two combined (0.30 mm), antennomere 3 cup-shaped, 4 (0.30 mm) shorter than the following antennomeres, 5 to 11 about equal in length (0.45 mm), 12 (terminal) (0.50 mm), antennal rami lanceolate in lateral view, 3 times the respective antennomere; terminal maxillary palpomere robust, securiform (0.40 mm), shorter than the preceding three combined (0.82 mm); terminal labial palpomere spindle-shaped (0.20 mm), twice as long as preceding one (0.10 mm). Thorax. Pronotum longer (2.5 mm) than wide (2.0 mm) (Fig. 8D ); integument chagreened, punctures twice as large as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a yellow-orange seta, disc convex, weakly elevated dorsally forming a small depression in the basal part of each side, posterior margin curved with middle notch, sides almost straight, anterior and posterior angles rounded; mesosternal suture complete; scutellum with small notch on posterior margin; each elytron 4.4 times as long (7.5 mm) as wide (1.7 mm), convex, with two longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length twice less than the length of MP1+2, radial cell closed, r3 vein present, r4 vein developed (reaching the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 8E ). 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 concave, sternite 8 with margin rounded; aedeagus with three teeth at the inner apex of paramere (Figs 1 , 8F-H ).
