Type locality.

Hidalgo, Mexico.

Type material examined.

Holotype ♂: "MEXICO: Hidalgo, Tlanchinol, La/ Cabaña. Bosque Mesófilo de montaña / 1478 m. N 21° 01.3343', W 98° 38.600' / Trampa de intercepción de vuelo 1. /13-20 -mayo- 2006. C. Ortiz y M.C. / Pedraza."

Remarks.

Cenophengus munizi is in a clade with C. mumui and C. huatulcoensis ( Vega-Badillo et al. 2021b), but can be distinguished from C. mumui by the shape and colour of the head and interantennal distance. Cenophengus munizi exhibits a rectangular-shaped head, which is yellow-brown coloured like the rest of the body, whereas in C. mumui , it is square and brown. In C. munizi , the interantennal distance is equal to the length of antennomere 1, whereas in C. mumui , it is less than the length of antennomere 1. Additionally, in C. munizi , the antennal rami are twice as long as the respective antennomere, whereas in C. mumui , they are 1.5 times as long as the respective antennomere. Finally, C. munizi can be distinguished from C. huatulcoensis by the interocular distance. The interocular distance is 2 times eye width in C. mumui , in C. huatulcoensis , it is 3 times eye width.

Diagnosis.

Integument smooth, head almost as wide as the pronotum, antennae long, more than twice the length of pronotum, antennal rami twice as long as respective antennomere, each elytron 6 times as long as wide; aedeagus one with spine at the inner apex of paramere.
