Cenophengus xiinbali Vega-Badillo et al. 2021a: 233.

Type locality.

Puerta Parada, Guatemala.

Type material examined.

Holotype ♂: "Guatemala: Guatemala Dept. / Puerta Parada km 14.5 carr. a / El Salvador 1840 m alt. / 8-15/VI/2013 Col. J.C Schuster" | CNIN. Paratype ♂: same data | CNIN.

Remarks.

Cenophengus xiinbali is morphologically similar to C. longicollis , but can be distinguished by the interocular distance and terminal maxillary palpomere. In C. xiinbali , the interocular distance is 3.5 times eye width, whereas in C. longicollis , it is 3 times longer. The terminal maxillary palpomere is as long as the preceding three combined in C. xiinbali , whereas in C. longicollis , it is longer than the preceding three combined.

Diagnosis.

Integument chagreened, antennae long, more than twice the length of pronotum, antennal rami twice as long as the respective antennomere, terminal maxillary palpomere as long as the preceding three combined and each elytron 4.1 times as long as wide; aedeagus with three teeth at the inner apex of paramere.

Redescription.

Male. Body length 8.15-8.30 mm, maximum body width 0.90-0.93 mm (pronotum). Body brown, except for pronotum, legs and two last abdominal segments orange (Fig. 32A, B ). Head.

Thorax. Pronotum longer (1.14-1.15 mm) 1.45 ± 0.007 mm, n = 2) than wide (0.90-0.93 mm) (0.915 ± 0.021 mm, n = 2) (Fig. 32D ); integument chagreened, punctures 3 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 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 (2.32-2.68 mm) (2.5 ± 0.254 mm, n = 2) as wide (0.62-0.64 mm) (0.63 ± 0.014 mm, n = 2), convex, without longitudinal costae, elytral apex rounded; hind wings with posterior radial vein (RP) length 3.2 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, evident (Fig. 32E ). 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 with three teeth at the inner apex of paramere (Fig. 32F-H ).

Female and immatures.

Unknown.

Distribution.
