Cenophengus tupae Vega-Badillo et al. 2021a: 232.
Type locality.
San Luis Potosí, 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. Paratype ♂: same data | CNIN.
Remarks.
Cenophengus tupae is morphologically similar to C. howdeni , but can be distinguished by the length of antennomere 1, the pronotal disc and interocular distance. In C. tupae , antennomere 1 is longer than the next two combined, whereas in C. howdeni , it is shorter than the next two combined. The pronotal disc is convex, weakly elevated dorsally, forming a small depression in the basal part of each side, in C. howdeni it has a groove along mid-line. The interocular distance is 3.0 times eye width in C. howdeni , in C. tupae , it is twice as long as eye width.
Diagnosis.
Body brown except for antennae yellow-brown, integument chagreened, antennae long, more than twice the length of pronotum, antennal rami 3 times as long as the respective antennomere, head almost as wide as the pronotum and each elytron 4.1 times as long as wide; aedeagus trilobed with three teeth at the inner apex of paramere.
Redescription.
Male. Body length 4.0-5.2 mm, maximum body width 0.60-0.70 mm (pronotum). Body brown, except for antennae and stripe on pronotum yellow-brown (Fig. 29A, B View Figure 29 ). Head. Wider (0.60-0.71 mm) (0.655 ± 0.077 mm, n = 2) than long (0.40-0.50 mm) (0.45 ± 0.07 mm, n = 2) (Fig. 29C View Figure 29 ), at eye level, almost as wider as the pronotum, integument chagreened, punctures 1.5 times as long as eye facets and separated by approximately 1.5 punctured diameters, each puncture bearing a yellow-brown seta; interantennal distance (0.04-0.05 mm) (0.045 ± 0.007 mm, n = 2) less than the length of antennomere 1 (0.16-0.18 mm) (0.17 ± 0.014 mm, n = 2); eyes 1/2 as long as head in lateral view, longer (0.27-0.30 mm) (0.285 ± 0.021 mm, n = 2) than wide (0.18-0.23 mm) (0.20 ± 0.035 mm, n = 2); interocular distance (0.35-0.40 mm) (0.375 ± 0.035 mm, n = 2) twice as long as eye width; antennae long (1.54-1.60 mm) (1.58 ± 0.042 mm, n = 2), more than twice the length of pronotum; antennomere 1 (0.16-0.18 mm) (0.17 ± 0.014 mm, n = 2) longer than the next two combined, antennomere 3 cup-shaped, 4 (0.12-0.13 mm) (0.125 ± 0.007 mm, n = 2) shorter than the following antennomeres, 5 to 11 about equal in length (0.14-0.15 mm) (0.145 ± 0.007 mm, n = 2), 12 (terminal) (0.17-0.20) (0.18 ± 0.021 mm, n = 2), antennal rami lanceolate in lateral view, 3 times as long as the respective antennomere; terminal maxillary palpomere robust, securiform (0.15-0.16 mm) (0.155 ± 0.007 mm, n = 2), shorter than the preceding three combined; terminal labial palpomere spindle-shaped (0.09-0.10 mm) (0.095 ± 0.007 mm, n = 2), 3 times as long as the preceding one (0.03) (0.03 ± 0 mm, n = 2). Thorax. Pronotum longer (0.72-0.80 mm) (0.76 ± 0.056 mm, n = 2) than wide (0.60-0.71 mm) (0.65 ± 0.077 mm, n = 2) (Fig. 29D View Figure 29 ); integument chagreened, punctures 1.5 times as long as eye facets and separated by approximately 1.5 punctured diameters, each puncture bearing a yellow-brown seta, convex disc, weakly elevated dorsally, forming a small depression in the basal part of each side, posterior margin almost straight with middle notch, sides almost straight, anterior angles rounded and posterior angles acute; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 4.1 times as long (1.57-1.90 mm) (1.73 ± 0.233 mm, n = 2) as wide (0.40-0.46 mm) (0.43 ± 0.021 mm, n = 2), convex, without longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length 3 times less than the length of MP1+2, radial cell closed, r3 vein present, r4 vein reduced (not reaching the RP or the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 29E View Figure 29 ). Legs: tarsomeres 1 and 2 of the prothoracic legs with a similar length and tarsomere 1 of meso- and metathoracic legs is longer than 2. Abdomen. Integument shiny, punctured, with long dense setae, sternite 7 with margin sinuate, sternite 8 with margin notched; aedeagus trilobed with three teeth at the inner apex of paramere (Fig. 29F-H View Figure 29 ).
