Cenophengus hnogamui Vega-Badillo et al. 2021a: 224.

Type locality.

Hidalgo, Mexico.

Type material examined.

Holotype ♂: "MEXICO: Hidalgo, Huasca de/ Ocampo, Rancho Santa Elena, / Presa San Carlos, 2430 m.a.s.l./ 20°08'04.5" N 98°30' 49.9" W. / 05/IX-03/X/2005. Trampa /Malaise. Col. A. Contreras / Meléndez y Reynoso" | CNIN. Paratypes ♂: same data | CNIN (2); CC-UAEH (1).

Remarks.

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

Diagnosis.

Integument smooth, long antennae more than twice the length of pronotum, antennal rami 1.5 times the respective antennomere and each elytron 4.7 times as long as wide with whitish colouration at the apex; aedeagus with three teeth at the inner apex of paramere.

Redescription.

Male. Body length 4.12-4.5 mm; maximum body width 0.60-0.63 mm (pronotum). Body dark brown, except for first three antennomeres and posterior part of the elytra yellow-brown coloured (Fig. 10A, B ). Head. Wider (0.6-0.63 mm) (0.62 ± 0.017 mm, n = 3) than long (0.37-0.43 mm) (0.4 ± 0.030 mm, n = 3) (Fig. 10C ), at eye level, almost as wide as the pronotum, integument smooth, punctures twice as large as eye facets and separated by approximately 0.5 punctured diameters, each puncture bearing a yellow-brown seta; interantennal distance (0.09-0.11 mm) (0.1 ± 0.01 mm, n = 3) less than the length of antennomere 1; eyes 1/2 as long as head in lateral view, longer (0.24-0.26 mm) (0.25 ± 0.01 mm, n = 3) than wide (0.15-0.16 mm) (0.153 ± 0.057 mm, n = 3); interocular distance (0.3-0.33 mm) (0.32 ± 0.017 mm, n = 3) twice as long as eye width; long antennae (2.12-2.23 mm) (2.18 ± 0.058 mm, n = 3), more than twice the length of pronotum; antennomere 1 (0.15-0.16 mm) (0.153 ± 0.005 mm, n = 3) as long as the next two combined, antennomere 3 cup-shaped, the 4th (0.10-0.11 mm) (0.103 ± 0.05 mm, n = 3) shorter than the following antennomeres; 5 to 11 about equal in length (0.21-0.23 mm) (0.22 ± 0.01 mm, n = 3, 12 (terminal) (0.28-0.31 mm) (0.29 ± 0.015 mm, n = 3), antennal rami lanceolate in lateral view, 1.5 times respective antennomere; terminal maxillary palpomere robust, securiform (0.18-0.21 mm) (0.21 ± 0.015 mm, n = 3), as long as the preceding three combined; terminal labial palpomere spindle-shaped (0.05-0.07 mm) (0.06 ± 0.01 mm, n = 3), 3 times as long as preceding one (0.02-0.03) mm (0.023 ± 0.015 mm, n = 3). Thorax. Pronotum longer (0.61-0.67 mm) (0.64 ± 0.03 mm, n = 3) than wide (0.60-0.65 mm) (0.64 ± 0.025 mm, n = 3) (Fig. 10D ); integument smooth, punctures twice as large as eye facets and separated by approximately 1 punctured diameter, with a yellow-brown seta in each puncture; disc convex, posterior margin almost straight without middle notch, sides convex, anterior and posterior angles rounded; mesosternal suture complete; scutellum with posterior margin rounded; each elytron 4.7 times as long (2.0-2.3 mm) (2.14 ± 0.15 mm, n = 3) as wide (0.40-0.50 mm) (0.45 ± 0.052 mm, n = 3), convex, without longitudinal costae, elytral apex acute; hind wings with posterior radial vein (RP) length 2.2 times less than the length of MP1+2, radial cell closed, r3 vein presented, r4 vein reduced (not reaching the RP or the radial cell), those of the anterior anal and posterior anal sectors (Fig. 10E ), evident. Legs: tarsomeres 1 and 2 of pro-, meso- and metathoracic legs with a similar length. 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. 10F-H ).

Immatures and females.

Unknown.
