Type locality.
Nayarit, Mexico.
Type material examined.
Holotype ♂: Mexico: "Tepic, Nayarit, / Mex. VII-28-53" "D. Rockefeller/ Mex. Exp. 1953/ C. & P. Vaurie" " Cenophengus major Wittmer" “Holotypus”. | AMNH. Holotype ♂: MEXICO: "Guerrero, Cerro Tuxpan/ Iguala, 12-VII-88. 8-2 pm. Col. R. Sánchez 11617" " Cenophengus / Cenophengus guerrerensis /Zaragoza" | CNIN. Paratypes ♂ (6): "Cerro Tuxpan/ Iguala, Gro. /1700 m. / 25-VI-87 /Col. R. Sánchez” | CNIN.
Remarks.
We synonymise C. guerrerensis with C. major , based on the observation of holotypes, being the body shape and total body length, as well as the maxillary palps and wing venation particularly important characters for its synonymisation. C. major is sister to C. magnus ( Vega-Badillo et al. 2021b), but can be distinguished by the elytral length and r3 vein. In C. magnus , each elytron is 4 times as long as wide, whereas in C. major , they are almost 4.5 times as long as wide; the r3 vein is absent in C. magnus , whereas in C. major , it is present.
Diagnosis.
Integument smooth, antennae long, more than twice the length of pronotum, antennal rami lanceolate in lateral view, 3.1 times the respective antennomere and each elytron 4.5 times as long as wide; aedeagus with three teeth at the inner apex of paramere.
Redescription.
Male. Body length 10.0-13.0 mm; maximum body width 1.33-1.64 mm (pronotum). Body brown, except for head, pronotum and scutellum yellow-orange; antennae and buccal parts dark brown (Fig. 16A, B View Figure 16 ). Head. Wider (1.13-1.47 mm) (1.35 ± 0.117 mm, n = 8) than long (0.65-0.72 mm) (0.692 ± 0.0218 mm, n = 8) (Fig. 16C View Figure 16 ), at eye level, less wide than the pronotum, integument smooth, punctures twice as large as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a yellow-orange seta; interantennal distance (0.11-0.16 mm) (0.15 ± 0.017 mm, n = 8) less than the length of antennomere 1 (0.35-0.40 mm) (0.353 ± 0.028 mm, n = 8); eyes 3/4 as long as head in lateral view, longer (0.51-0.58 mm) (0.54 ± 0.021 mm, n = 8) than wide (0.28.0.38 mm) (0.33 ± 0.035 mm, n = 8); interocular distance (0.66-0.75 mm) (0.70 ± 0.035 mm, n = 8) 1.8 times eye width; antennae long (3.40-4.03 mm) (3.8 ± 0.168 mm, n = 8), more than twice the length of pronotum; antennomere 1 (0.35-0.40 mm) (0.353 ± 0.028 mm, n = 8) longer than next two combined, antennomere 3 cup-shaped, 4 (0.30-0.40 mm) (0.38 ± 0.035 mm, n = 8) shorter than following antennomeres, 5 to 11 about equal in length (0.33-0.40 mm) (0.35 ± 0.025 mm, n = 8), 12 (terminal) (0.50-0.55 mm) (0.52 ± 0.24 mm, n = 8), antennal rami lanceolate in lateral view, 3 times the respective antennomere; terminal maxillary palpomere robust, securiform (0.38-0.46 mm) (0.42 ± 0.029 mm, n = 8), shorter than the preceding three combined; terminal labial palpomere spindle-shaped (0.25-0.27 mm) (0.22 ± 0.030 mm, n = 8), twice as long as preceding one (0.10-0.12 mm) (0.102 ± 0.007 mm, n = 8). Thorax. Pronotum longer (1.65-1.84 mm) (1.71 ± 0.071 mm, n = 8) than wide (1.33-1.64 mm) (1.45 ± 0.122 mm, n = 8) (Fig. 16D View Figure 16 ); integument smooth, punctures twice as large as eye facets and separated by approximately 1.5 punctured diameters coarsely punctured, each puncture bearing a yellow-orange seta, convex disc, 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 incomplete; scutellum with posterior margin rounded; each elytron 4.5 times as long (4.0-5.0 mm) (4.59 ± 0.332 mm, n = 8) as wide (0.92-1.16 mm) (1.05 ± 0.084 mm, n = 8), convex, with one 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. 16E View Figure 16 ). 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, sternite 8 with margin rounded; aedeagus with three teeth at the inner apex of paramere (Fig. 16F-H View Figure 16 ).
