Cenophengus magnus Zaragoza-Caballero, 1988: 651.
Type locality.
Mexico.
Type material.
Holotype ♂: "Nuevo Leon, Mexico (92°44'N; 99°56'W), 16 de Julio de 1979, 1 800 m, Col. D.C. Darling" | CUIC.
Remarks.
Cenophengus magnus is sister to C. major ( 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, 3 times the respective antennomere, scutellum almost quadrangular, with small notch on posterior margin and each elytron 4 times as long as wide, with one longitudinal costa; aedeagus with three teeth at the inner apex of paramere.
Redescription.
Male. Body length 11.0-12.0 mm; maximum body width 1.74-1.80 mm (pronotum). Body brown, except for head, pronotum and scutellum yellow-orange; antennae and buccal parts dark brown (Fig. 15A, B View Figure 15 ). Head. Wider (1.30-1.35 mm) (1.325 ± 0.035 mm, n = 2) than long (0.75-0.80 mm) (0.77 ± 0.035 mm, n = 2) (Fig. 15C View Figure 15 ), at eye level, less wide than the pronotum, integument smooth, punctures 2.5 times as long as eye facets and separated by approximately 0.5 punctured diameters, each puncture bearing a yellow-orange seta; interantennal distance (0.14-0.16 mm) (0.15 ± 0.014 mm, n = 2) less than the length of antennomere 1 (0.31-0.34 mm) (0.325 ± 0.021 mm, n = 2); eyes 3/4 as long as head in lateral view, longer (0.55-0.6 mm) (0.57 ± 0.035 mm, n = 2) than wide (0.3-0.35 mm) (0.325 ± 0.035 mm, n = 2); interocular distance (0.65-0.7 mm) (0.675 ± 0.035 mm, n = 2) 1.9 times eye width; antennae long (4.02-4.27 mm) (4.14 ± 0.176 mm, n = 2) more than twice the length of pronotum; antennomere 1 (0.31-0.34 mm) (0.325 ± 0.021 mm, n = 2) longer than next two combined, antennomere 3 cup-shaped, 4 (0.30-0.33 mm) (0.315 ± 0.3 mm, n = 2) shorter than following antennomeres, 5 to 11 about equal in length (0.38-0.40 mm) (0.39 ± 0.014 mm, n = 2), 12 (terminal) (0.50-0.55 mm) (0.525 ± 0.035 mm, n = 2), antennal rami lanceolate in lateral view, 3 times the respective antennomere; terminal maxillary palpomere robust, securiform (0.35-0.40 mm) (0.375 mm ± 0.035 mm, n = 2), twice as short as the preceding three combined; terminal labial palpomere spindle-shaped (0.16-0.17 mm) (0.165 ± 0.007 mm, n = 2), 3 times as long as preceding one (0.05-0.07 mm) (0.06 ± 0.014 mm, n = 2). Thorax. Pronotum longer (1.9-2.0 mm) (1.95 ± 0.070 mm, n = 2) than wide (1.74-1.80 mm) (1.77 ± 0.042 mm, n = 2) (Fig. 15D View Figure 15 ); integument smooth, punctures twice as large as eye facets and separated by approximately 1 punctured diameter, 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, sides almost straight, anterior and posterior angles rounded; mesosternal suture incomplete; scutellum with small notch on posterior margin; each elytron 4 times as long (4.52-4.80 mm) (4.66 ± 0.197 mm, n = 2) as wide (1.1-1.2 mm) (1.15 ± 0.070 mm, n = 2), 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 absent, r4 vein developed (reaching the RP and the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 15E View Figure 15 ). Legs: tarsomeres 1 and 2 of the prothoracic legs with a similar length and tarsomere 1 of 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 (Fig. 15F-H View Figure 15 ).
Female and immatures.
Unknown.
Distribution.
