Cenophengus kikapu Vega-Badillo et al. 2021a: 227.
Type locality.
Coahuila, Mexico.
Type material examined.
Holotype ♂: "MEXICO: El Cañón, Cuatro/ Ciénegas, Coahuila, Col. MTO/ y UOGV 21/feb/2012 Col. / nocturna luz blanca" | CNIN. Paratypes ♂: same data | CNIN (2).
Remarks.
Cenophengus kikapu is morphologically similar to C. sonoraensis , but can be distinguished by the width of the head and the terminal maxillary palpomere. In C. sonoraensis , the head is almost as wide as the pronotum, whereas in C. kikapu , the head is wider than the pronotum. In addition, the terminal maxillary palpomere is as long as the preceding three combined in C. sonoraensis , whereas in C. kikapu , it is longer than the preceding three combined.
Diagnosis.
Head almost as wide as pronotum, integument chagreened, antennae less than twice the length of the pronotum, antennal rami twice as long as respective antennomere, terminal maxillary palpomere as long as preceding three combined, each elytron 3.6 times as long as wide; aedeagus with three teeth at the inner apex of paramere.
Redescription.
Male. Body length 4.64-5.0 mm; maximum body width 0.80-0.82 mm (pronotum). Body dark brown, except for pronotum, legs and two last abdominal segments yellow-orange (Fig. 13A, B View Figure 13 ). Head. Wider (0.80-0.81 mm) (0.806 ± 0.005 mm, n = 3) than long (0.50-0.52 mm) (0.506 ± 0.011 mm, n = 3) (Fig. 13C View Figure 13 ), at eye level, almost as wide as pronotum, integument chagreened, punctures 1.5 times as long as eye facets and separated by approximately 2 punctured diameters, each puncture bearing a yellow-brown seta; interantennal distance (0.07-0.09 mm) (0.08 ± 0.01 mm, n = 3) less than the length of antennomere 1 (0.16-0.18 mm) (0.17 ± 0.01 mm, n = 3); eyes 3/4 as long as head in lateral view, longer (0.35-0.37 mm) (0.356 ± 0.011 mm, n = 3) than wide (0.19-0.20 mm) (0.196 ± 0.005 mm, n = 3); interocular distance (0.40-0.42 mm) (0.41 ± 0.01 mm, n = 3) twice eye width; antennae short (1.63-1.73 mm) (1.68 ± 0.05 mm, n = 3) less than twice the length of the pronotum; antennomere 1 (0.16-0.18 mm) (0.17 ± 0.01 mm, n = 3) is longer than the next two combined, antennomere 3 cup-shaped, 4 (0.11-0.12 mm) (0.116 ± 0.005 mm, n = 3) shorter than the following antennomeres, 5 to 11 about equal in length (0.15-0.17 mm) (0.16 ± 0.01 mm, n = 3), 12 (terminal) (0.20-0.21 mm) (0.203 ± 0.005 mm, n = 3), antennal rami lanceolate in lateral view, twice as long as the respective antennomere; terminal maxillary palpomere robust, securiform (0.28-0.30 mm) (0.286 ± 0.011 mm, n = 3), as long as the preceding three combined; terminal labial palpomere spindle-shaped (0.05-0.06 mm) (0.056 ± 0.005 mm, n = 3), 3 times as long as preceding one (0.02-0.03 mm) (0.26 ± 0.005 mm, n = 3). Thorax. Pronotum longer (1.07-1.09 mm) (1.073 ± 0.015 mm, n = 3) than wide (0.80-0.82 mm) (0.81 ± 0.01 mm, n = 3) (Fig. 13D View Figure 13 ); integument chagreened, punctures 1.5 times as long as eye facets and separated by approximately 2 punctured diameters, 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 almost straight with a middle notch, sides almost straight, anterior and posterior angles rounded; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 3.6 times as long (1.7-2.0 mm) (1.89 ± 0.015 mm, n = 3) as wide (0.44-0.50 mm) (0.46 ± 0.030 mm, n = 3), convex, without longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length 3.5 times less than the length of MP1+2, radial cell closed, r3 vein absent, r4 vein developed (reaching the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 13E View Figure 13 ). Legs: tarsomeres 1 and 2 of pro-, meso- and metathoracic legs with a similar length. Abdomen. Integument shiny, punctured, with long dense setae, sternite 7 with margin sinuate, sternite 8 with margin notched; aedeagus with three teeth at the inner apex of paramere (Fig. 13F-H View Figure 13 ).
Female and immatures.
Unknown.
