Type locality.

USA.

Type material examined.

Holotype ♂: USA: "Az. Pima Co. Tucson Mts. / Saguaro Nat. Mon./ 5-APR-80/ Cicero" "Red Hills / visiter center" "Note Luminescent spots/ vaguely indicated as/ two white patches on/ last tergite" " Cenophengus / Cenophengus ciceroi det. W. Wittmer" “HOLOTYPUS” "Type No./ 100336 / USMN" | NMNH.

Remarks.

Cenophengus ciceroi is sister to C. gorhami ( Vega-Badillo et al. 2021b), but can be distinguished by the antennal rami length, interocular distance and the terminal maxillary palpomere. In C. ciceroi , the interocular distance is 1.5 times eye width, whereas in C. gorhami , it is twice longer. The terminal maxillary palpomere is as long as the preceding three combined in C. ciceroi ; in C. gorhami , it is shorter than the preceding three combined. Additionally, in C. ciceroi , the antennal rami are twice as long as the respective antennomere, whereas in C. gorhami , they are 1.5 times as long as the respective antennomere.

Diagnosis.

Integument chagreened, antennae less than twice the length of the pronotum, antennal rami twice as long as the respective antennomere, pronotum longer than wide and each elytron 3.3 times as long as wide; aedeagus with three teeth at the inner apex of paramere.

Redescription.

Male. Body length 4.20 mm; maximum body width 0.60 mm (pronotum). Head dark brown to black, rest of the body, antennae and legs included, yellow to pale brown (Fig. 6A, B ). Head. Wider (0.75 mm) than long (0.42 mm), at eye level, wider than the pronotum (Fig. 6C ), integument chagreened, punctures as large as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a yellow-orange seta; interantennal distance (0.04 mm) less than the length of antennomere 1 (0.16 mm); eyes 3/4 as long as head in lateral view, longer (0.37 mm) than wide (0.17 mm); interocular distance (0.25 mm) 1.5 times eye width; antennae short (1.51 mm) less than twice the length of the pronotum; antennomere 1 (0.16 mm) longer than the next two combined, antennomere 3 cup-shaped, 4 (0.10 mm) shorter than following antennomeres, 5 to 11 about equal in length (0.15 mm), 12 (terminal) (0.20 mm), antennal rami lanceolate in lateral view, twice as long as the respective antennomere; terminal maxillary palpomere robust, securiform (0.23 mm), as long as the preceding three combined (0.24 mm); terminal labial palpomere spindle-shaped (0.1), 3 times as long as preceding one (0.03 mm). Thorax. Pronotum longer (0.89 mm) than wide (0.64 mm) (Fig. 6D ); integument chagreened with punctures as large as facets and separated by approximately 2 punctured diameters, each puncture bearing a yellow-orange seta; disc convex, with groove along mid-line, 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 3.3 times as long (1.88 mm) as wide (0.56 mm), convex, without longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length 5 times less than the length of MP1+2, radial cell closed, r3 vein absent, r4 vein reduced (not reaching the RP or the radial cell), those of the anterior anal and posterior anal sectors, absent (Fig. 6E ). Legs: tarsomere 1 of pro-, meso- and meathoracic legs is longer than 2. 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. 6F-H ).

Female and immatures.
