Type locality.

Hidalgo, Mexico (Fig. 19 ).

Type material examined.

Holotype ♂: "Mexico: Santiago de Anaya/ Hgo.20°24'0761"N/ 98°53'1797"O, 28-29 agosto /2017 Col. A. Ibarra Vázquez” | CNIN. Paratype ♂: "Mexico, Atotonilco El / Grande, 3 km NE Montecillos/ Bosque Juniperus-Quercus. 20° /18' 9" N, 98° 36'17" W. Trampa de / Intercepción de vuelo 12 al 19-VII-/2010. J. Márquez y J. Asiain" | CC-UAEH.

Remarks.

Cenophengus mboi is morphologically similar to C. predregalensis , but can be distinguished by the colour of the body and terminal maxillary palpomere. In C. mboi , the body is dark brown, whereas in C. pregalensis , it is dark brown and the pronotum yellow-orange. Terminal maxillary palpomere is as long as the preceding three combined in C. mboi , in C. pedregalensis , it is longer than the preceding three combined.

Diagnosis.

Body black, integument chagreened, antennae long, more than twice the length of pronotum, antennal rami twice as long as the respective antennomere, terminal maxillary palpomere is as long as the preceding three combined and each elytron 4.3 times as long as wide; aedeagus with three teeth at the inner apex of paramere.
