Type locality.

Belize.

Type material.

Holotype ♂: "BELIZE: Orange Walk Dist/ Rio Bravo Conserv. Area/18. IV. 1995; PKKovarik &/ JShuey colrs; light trap" "From the Michael Ivie Collection" | NMNH.

Remarks.

Cenophengus tsiik is morphologically similar to C. cuicatlaensis , but can be distinguished by the interocular distance and the terminal maxillary palpomere. In C. tsiik , interocular distance is 3 times eye width, whereas in C. cuicatlaensis , it is twice as long as eye width. Terminal maxillary palpomere is shorter than the preceding three combined in C. tsiik , in C. cuicatlaensis , it is longer than the preceding three combined.

Diagnosis.

Integument chagreened, head almost as wide as the pronotum, antennae less than twice the length of the pronotum, antennal rami 1.5 times the respective and antennomere, each elytron 2.8 times as long as wide; aedeagus with three teeth at the inner apex of paramere.

Description.

Male. Body length 5.50 mm, maximum body width 0.65 mm (pronotum). Body dark brown, except for the antennae buccal parts, legs and the two last sternites are pale brown to yellow (Fig. 28A, B ). Head. Wider (0.68 mm) than long (0.55 mm) (Fig. 28C ), at eye level, almost as wide as the pronotum (0.65 mm), integument chagreened, punctures twice as long as eye facets and separated by approximately 0.5 punctured diameters, each puncture bearing a yellow-brown seta; interantennal distance (0.09 mm) less than the length of antennomere 1 (0.18 mm); eyes 1/2 as long as head in lateral view, longer (0.30 mm) than wide (0.13 mm); interocular distance (0.40 mm) 3 times eye width; antennae short (1.58 mm less than twice the length of the pronotum; antennomere 1 (0.18 mm) is longer than the next two combined (0.10 mm), antennomere 3 cup-shaped, 4 (0.10 mm) shorter than following antennomeres, 5 to 11 about equal in length (0.15 mm), 12 (terminal) (0.17 mm), antennal rami lanceolate in lateral view, 1.5 times the respective antennomere; terminal maxillary palpomere robust, securiform (0.25 mm), shorter than the preceding three combined; terminal labial palpomere spindle-shaped (0.09 mm), 3 times as long as preceding one (0.03 mm). Thorax. Pronotum longer (0.80 mm) than wide (0.65 mm) (Fig. 28D ); integument chagreened, punctures twice 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 equal to the median length of the pronotum, posterior margin curved with middle notch, sides almost straight, anterior and posterior angles rounded; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 2.8 times as long (1.12 mm) as wide (0.40 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 developed (reaching the radial cell), those of the anterior anal and posterior anal sectors, slightly evident (Fig. 28E ). 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 notched; aedeagus with three teeth at the inner apex of paramere (Fig. 28F-H ).

Female and immatures.

Unknown.

Distribution.

Belize (Fig. 19 ).

Etymology.
