Cenophengus punctatissimus Wittmer, 1976: 452.

Type locality.

San Luis Potosí, Mexico.

Type material examined.

Holotype ♂: MEXICO: "2 km S Tamazunchale, / San Luis Potosí (R. 1 km 363) / 31-V-1948, 700 ft / tropical canyon-jungle" "at light/ F, Werner/ W. Nutting" "Type No. / 73888/ USNM" | NMNH.

Remarks.

Cenophengus punctatissimus is morphologically similar to C. mboi , but can be distinguished by the interocular distance. In C. punctatissimus , the interocular distance is 2.5 times eye width, whereas in C. mboi , it is 3 times eye width. Additionally, in C. punctatissimus , the posterior radial vein length is 5.3 times less than the length of MP1+2, whereas in C. pedregalensis , it is twice less than the length of MP1+2.

Diagnosis.

Body dark brown, integument chagreened, head less wide than the pronotum, antennae long, more than twice the length of pronotum, antennal rami twice as long as the respective antennomere and each elytron 5.4 times as long as wide; aedeagus with three teeth at the inner apex of paramere.

Redescription.

Male. Body length 10.5 mm, maximum body width 1.0 mm (pronotum). Body dark brown, except for buccal parts, coxa, trochanter, femur and two last sternites yellowish-coloured (Fig. 25A, B View Figure 25 ). Head. Wider (0.91 mm) than long (0.8 mm) (Fig. 25C View Figure 25 ), at eye level, less wide than the pronotum, integument chagreened, punctures 2.5 times as long as eye facets and separated by approximately 0.5 punctured diameters, each puncture bearing a yellow-brown seta; interantennal distance (0.10 mm) less than the length of antennomere 1 (0.20 mm); eyes 1/2 as long as head in lateral view, longer (0.35 mm) than wide (0.21 mm); interocular distance (0.52 mm) 2.5 times eye width; antennae long (2.42 mm) more than twice the length of pronotum; antennomere 1 (0.20 mm) as long as the next two combined, antennomere 3 cup-shaped, 4 (0.20 mm) shorter than the following antennomeres, 5 to 11 about equal in length (0.25), 12 (terminal) (0.30 mm), antennal rami lanceolate in lateral view, twice as long as the respective antennomere; terminal maxillary palpomere robust, securiform (0.40 mm), as long as the preceding three combined (0.40 mm); terminal labial palpomere spindle-shaped (0.15 mm), 3 times as long as preceding one (0.05 mm). Thorax. Pronotum longer (1.40 mm) than wide (1.0 mm) (Fig. 25D View Figure 25 ); integument chagreened, punctures 2.5 times as long as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a yellow-brown seta, disc convex, with a longitudinal carina in posterior portion of pronotum strongly visible, with a length exceeding the median length of the pronotum, posterior margin curved with middle notch, sides almost straight, anterior angles rounded and posterior angles acute; mesosternal suture incomplete; scutellum with posterior margin rounded; each elytron 5.4 times as long (3.48 mm) as wide (0.64 mm), convex, without longitudinal costae, elytral apex blunted; hind wings with posterior radial vein (RP) length 5.3 times less than the length of MP1+2, radial cell closed, r3 vein present, r4 vein reduced (reaching the RP or the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 25E View Figure 25 ). Legs: tarsomere 1 of pro-, 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 concave; aedeagus with three teeth at the inner apex of paramere (Fig. 25F-H View Figure 25 ).

Female and immatures.
