Type locality.

Puebla, Mexico.

Type material examined.

Holotype ♂: Mexico: "Puebla, Plata, / VII-75 / 960 m.a.s.l. / J. Bueno / Col. Noc." | CNIN. Paratype ♂: "Mexico: Hidalgo, Ixtlahuaco / Alt. 1550 m. 17- 07- 1983 / Luz incandescente amarilla / colecta nocturna, Bosque / Mesófilo de montaña. / Col. R. Terrón” (1) | CNIN.

Remarks.

Cenophengus wittmeri is morphologically similar to C. marmoratus , but can be distinguished by the colour of the body and the terminal maxillary palpomere. In C. wittmeri , its body is brown, except for the middle part of the pronotum that is dark brown, whereas in C. marmoratus , it is yellow or pale brown, the pronotum partially interrupted by darker brown spots. The terminal maxillary palpomere is as long as the preceding three combined in C. wittmeri , in C. marmoratus , it is shorter than the preceding three combined. Additionally, in C. wittmeri , the posterior radial vein length is twice less than the length of MP1+2, whereas in C. marmoratus , it is 1.6 times less than the length of MP1+2.

Diagnosis.

Body brown, except for middle part of pronotum, integument chagreened, head almost as wide as the pronotum, antennae long, more than twice the length of pronotum, antennal rami twice as long as the respective antennomere and each elytron 3.7 times as long as wide; aedeagus with three teeth at the inner apex of paramere.

Redescription.

Male. Body length 5.80-9.20 mm, maximum body width 0.87-1.04 mm (pronotum). Body brown, except for middle part of pronotum and last two sternites dark brown, elytral apex whitish (Fig. 31A, B ).

Thorax. Pronotum longer (0.94-1.30 mm) (1.04 ± 0.173 mm, n = 4) than wide (0.87-1.04 mm) (0.94 ± 0.081 mm, n = 4) (Fig. 31D ); integument chagreened, punctures twice as long as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a yellow-brown 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 incomplete; scutellum with posterior margin rounded; each elytron 3.5 times as long (1.7-3.5 mm) (2.55 ± 0.741 mm, n = 4) as wide (0.48-1.0 mm) (0.74 ± 0.216 mm, n = 4), convex, without 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. 31E ).
