( Figs. 13–16 View FIGURES 13 – 22. 13 – 16 )

Description. Integument dark-brown, almost black on some areas; gula and palpi reddish-brown. Pubescence brownish-yellow; setae yellow to dark-brown.

Head. Frons transverse, coarsely, abundantly punctate. Vertex and area behind eyes coarsely, abundantly punctate. Pubescence on dorsal surface of head not obscuring integument, organized in numerous small tufts, denser around eyes, with abundant long yellow setae. Pubescence behind inferior ocular lobes moderately dense, not organized in tufts, with long yellow setae. Pubescence on genal margins dense, distinctly sparser on central area, with long yellow setae. Inferior ocular lobes about as long as 1.3 times genal length; distance between superior ocular lobes equal to 0.6 times scape length; distance between inferior ocular lobes, in frontal view, equal to 1.1 times scape length. Antennae as long as 1.6 times elytral length; scape, pedicel and antennomeres moderately coarsely, abundantly punctate; pubescence not obscuring punctures; pubescence forming ring on basal one-third of antennomeres V–X, and on basal and distal third of antennomere XI; all segments with long yellow setae throughout (some dark-brown setae intermixed), gradually shorter and sparser from scape to antennomere XI; antennal formula (ratio) based on antennomere III: scape = 0.59; pedicel = 0.16; IV = 0.93; V = 0.41; VI = 0.43; VII = 0.41; VIII = 0.36; IX = 0.32; X = 0.30; XI = 0.34.

Thorax. Pronotum coarsely, abundantly punctate; pubescence not obscuring punctures; denser on wide longitudinal band at center, from near base to base to anterior third, and two oblique basal narrow bands laterally, from near base to middle; with long, moderately abundant yellow to dark-brown setae (former more abundant). Prothorax laterally coarsely punctate laterally (punctures slightly smaller than on pronotum); pubescence denser than on pronotum, with long yellow setae; tubercle placed near middle, moderately large, triangular. Pubescence on prosternum less dense than on lateral of prothorax; with long yellow setae on basal half. Metasternum coarsely, abundantly punctate laterally, gradually sparser and smaller medially; pubescence moderately dense, not obscuring punctures. Scutellum laterally pubescent, with small pubescence centrally on two-thirds, glabrous on distal onethird. Elytra coarsely, abundantly punctate (punctures gradually smaller towards apex); pubescence variable, forming dense small patches, but distinctly sparser between them; with long, moderately abundant yellowish to dark-brown setae throughout; apex rounded.

Abdomen. Urosternites moderately coarsely, sparsely punctate; pubescence moderately dense, not obscuring punctures; with long, yellow setae. Legs. Pubescence on ventral side of femora abundant, not obscuring punctures; with long, yellow setae. Metatarsomere V as long as II–III together.

Female paratype. Antennae 1.5 times elytral length.

Dimensions in mm (male/female). Total length, 8.8/9.3; length of prothorax at center, 1.9/1.7; widest width of prothorax (between apices of tubercles), 2.2/2.3; anterior width of prothorax, 1.6/1.8; posterior width of prothorax, 1.8/2.0; humeral width, 2.6/2.8; elytral length, 6.0/6.5.

Type material. Holotype male from MEXICO, Veracruz: Lake Catemaco, 25.VI.1969, Bright & Campbell col. ( MZSP). Paratype female, from MEXICO, Chiapas: 17 km W Tuxtla Gutiérrez, 21–25.VI.1987, J. E. Wappes col. ( ACMT).

Diagnosis. Eupogonius azteca differs from E. major Bates, 1885 as follows: body robust; proportion between elytra, and head plus prothorax shorter (2.15 times in male; 2.40 times in female); punctation on vertex and pronotum sparser. In E. major the body is slender, the proportion between elytra, and head plus prothorax is larger (2.6 times), and the punctation on vertex and pronotum is sparser. It differs from E. infimus (Thomson, 1868) by the metasternum being coarsely punctate laterally (finely in E. infimus ), and by the body being more robust. It is also very similar to E. annulicornis Fisher, 1926 , but differs mainly by the pubescence not forming wide ring on basal half or two-thirds of antennomeres III–IV.

Remarks. Eupogonius azteca can be included in the alternative of couplet “32”, from Breuning (1974). However, the first alternative in this couplet was a mistake by Breuning (1974). Bates (1885) wrote in the original description of E. subnudus : “antennis articulis a 5º basi eano-griseis.” Breuning recorded on his alternative couplet (translation): “Antennae with unicolor pubescence…. subnudus Bat. ” According to Bates (1885) the integument of the basal half of antennomere IV and entire surface of X–XI are light; Breuning (1974) probably intended to say that the integument is unicolored in all antennal segments of E. subnudus , and not the pubescence. We modified this couplet to include the new species, and correct the original information by him.

32. Antennal segments with a single color................................................................... 32’ - Part of antennomere IV and all antennomere XI lighter than the other antennomeres............. E. scutellaris Bates, 1885 32’(32).“The upper surface with very little light-coloured tomentum, and on the elytra only, the head and thorax being bare” ( Bates

Etymology. Azteca : relating to the “Aztec civilization” which inhabited Mexico (country of the type locality of the species); noun in the nominative singular in apposition to the generic name.
