Cenophengus mumui Vega-Badillo et al. 2021a: 231.
Type locality.
San Luis Postosí, Mexico.
Type material examined.
Holotype ♂: "Mexico, San Luis Potosí, / Tamasopo. Cerro al noroeste/ del cafetal, 01-06-15, / N 21°55.47' W 99°24.95' Col. / Jessica Ríos” | CNIN.
Remarks.
Cenophengus mumui is in a clade with C. munizi and C. huatulcoensis ( Vega-Badillo et al. 2021b), but can be distinguished from C. munizi by the shape and colour of the head. In C. mumui , the head is square and brown, whereas in C. munizi , it is rectangular-shaped. Additionally, in C. mumui , the antennal rami are 1.5 times as long as the respective antennomere, whereas in C. munizi , they are twice as long as the respective antennomere. Finally, C. mumui can be distinguished from C. huatulcoensis by the interantennal distance and interocular distance. In C. huatulcoensis , the interantennal distance is equal to the length of antennomere 1, whereas in C. mumui , it is less than the length of antennomere 1. The interocular distance is 2 times eye width in C. mumui , in C. huatulcoensis , it is 3 times eye width.
Diagnosis.
Body yellow, except for head brown, integument smooth, antennae long more than twice the length of pronotum, antennal rami 1.5 times the respective antennomere, pronotum as long as wide and each elytron 4.3 times as long as wide; aedeagus with one spine at the inner apex of paramere.
Redescription.
Male. Body length 3.5-4.0 mm; maximum body width 0.56-0.59 mm (pronotum). Body yellow, except for head brown (Fig. 20A, B View Figure 20 ). Head.

Thorax. Pronotum as long (0.58-0.62 mm) (0.6 ± 0.028 mm, n = 2) as wide (0.56-0.59 mm) (0.575 ± 0.021 mm, n = 2) (Fig. 20D View Figure 20 ); integument smooth, punctures twice as long as eye facets and separated by approximately 2 punctured diameters, with a yellow-coloured seta in each puncture; disc convex, weakly elevated dorsally forming a small depression in the basal part of each side, posterior margin almost straight with middle notch, sides convex, anterior and posterior angles rounded; mesosternal suture incomplete; scutellum with posterior margin rounded; each elytron 4.3 times as long (1.44-1.62 mm) (1.53 ± 0.127 mm, n = 2) as wide (0.34-0.37 mm) (0.355 ± 0.021 mm, n = 2), convex, without longitudinal costae, elytral apex right angled; posterior radial vein (RP) length 4.8 times less than the length of MP1+2, radial cell closed and slightly defined, r3 and r4 veins absent, those of the anterior anal and posterior anal sectors, absent (Fig. 20E View Figure 20 ).
