Cenophengus longicollis Wittmer, 1976: 451.

Type locality.

Texas, USA.

Type material examined.

Holotype ♂: "U.S. A: 3 mi. NE. of / Porvenir/ Presidio Co. /Tex. 26.IX.46. / B. Patterson, / J. M. SchmidI" "California Academy / of Sciences /Type No. 12986". | FMNH. Paratype ♂: "Texas: Jeff Davis Co. /Ft. Davis, Limpia Cayon/ 16.VII.1964 St. Pla" "At light/ W. Suter leg." (1) | FMNH. "New Mexico: White´s City/ Eddy Co. 8. IX. 1952" "C.N.H.M 1960/ Borys Malkin/ Coleoptera Colln." (1) | FMNH.

Remarks.

Cenophengus longicollis is morphologically similar to C. xiinbali , but can be distinguished by the interocular distance and the terminal maxillary palpomere. In C. longicollis , the interocular distance is 3.5 times longer than eye width, whereas in C. xiinbali , it is 2.5 times longer. The terminal maxillary palpomere is longer than the preceding three combined in C. longicollis , whereas in C. xiinbali , it is as long as the preceding three combined.

Diagnosis.

Integument chagreened, antennae less than twice the length of the pronotum, antennal rami twice as long as the respective antennomere and each elytron 3.5 times as long as wide; aedeagus with three teeth at the inner apex of paramere.

Redescription.

Male. Body length 5.6-7.2 mm; maximum body width 0.82-1.0 mm (pronotum). Head black; antennae black to brown, pronotum and scutellum yellow-orange; wingtips black to brown, sometimes only at the base poorly lit, legs and lower yellow to yellow-orange (Fig. 14A, B ). Head. Wider (0.83-1.0 mm) (0.91 ± 0.074 mm, n = 4) than long (0.5-0.6 mm) (0.53 ± 0.038 mm, n = 4) (Fig. 14C ), at eye level, a little wider than the pronotum, integument chagreened, punctures 2.5 times as long as eye facets and separated by approximately 1 punctured diameter, each puncture bearing a brown seta; interantennal distance (0.09-0.11 mm) (0.09 ± 0.010 mm, n = 4) less than the length of antennomere 1 (0.17-0.23 mm) (0.20 ± 0.026 mm, n = 4); eyes 3/4 as long as head in lateral view, longer (0.36-0.46 mm) (0.39 ± 0.034 mm, n = 4) than wide (0.20-0.25 mm) (0.22 ± 0.022 mm, n = 4); interocular distance (0.42-0.5 mm) (0.46 ± 0.033 mm, n = 4) 3.5 times eye width; antennae short (1.75-2.21 mm) (0.22 ± 0.014 mm, n = 4) less than twice the length of the pronotum; antennomere 1 (0.17-0.23 mm) (0.20 ± 0.026 mm, n = 4) a little longer than next two combined, antennomere 3 cup-shaped, 4 (0.15-0.17 mm) (0.16 ± 0.01 mm, n = 4) shorter than the following antennomeres, 5 to 11 about equal in length (0.16-0.20 mm) (0.178 ± 0.017 mm, n = 4), 12 (terminal) (0.20-0.30 mm) (0.22 ± 0.037 mm, n = 4), antennal rami lanceolate in lateral view, twice as long as the respective antennomere; terminal maxillary palpomere robust, securiform (0.25-0.30 mm) (0.27 ± 0.023 mm, n = 4), is longer than the preceding three combined; terminal labial palpomere spindle-shaped (0.10-0.11 mm) (0.105 ± 0.01 mm, n = 4), 3.5 times as long as preceding one (0.03-0.04 mm) (0.35 ± 0.005 mm, n = 4). Thorax. Pronotum longer (1.01-1.20 mm) (1.12 ± 0.088 mm, n = 4) than wide (0.82-1.0 mm) (0.9 ± 0.080 mm, n = 4) (Fig. 14D ); integument chagreened, punctures twice as large 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 curved, sides almost straight, anterior angles rounded and posterior angles acute; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 3.5 times as long (1.72-2.04 mm) (2.03 ± 0.263 mm, n = 4) as wide (0.52-0.65 mm) (0.59 ± 0.071 mm, n = 4), 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 absent, r4 vein developed (reaching the radial cell), those of the anterior anal and posterior anal sectors, evident (Fig. 14E ). 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. 14F-H ).
