Eupogonius monzoni Wappes and Santos-Silva , sp. nov.

( Fig. 67–70 )

Description. Female. Integument mostly black; central area of gulamentum brown; femora reddishbrown on basal area; tibiae reddish-brown on basal half; central area of abdominal ventrites II–IV reddish-brown.

Head. Frons finely, abundantly punctate; with white pubescence not obscuring integument (more yel- lowish white depending on light intensity), with abundant, long, erect dark setae interspersed. Vertex with sculpturing as in frons; with yellow pubescence close to eyes, partially obscuring integument, sparser, brown centrally, with long, erect dark setae interspersed. Area behind eyes finely, abundantly punctate; with dense yellow pubescence, covering wider area toward gena; with long, erect dark setae interspersed close to eye. Genae finely, sparsely punctate, central area close to eye smooth; with dense yellow pubescence toward inferior area, sparser, white toward clypeus, smooth area glabrous. Antennal tubercles with sculpturing anteriorly and posteriorly as on frons, centrally smooth; with white pubescence not obscuring integument (more yellowish white depending on light intensity), smooth area glabrous, with long, erect dark setae interspersed. Eyes finely punctate; lower eye lobes slightly longer than gena; distance between upper eye lobes 0.35 times length of scape; in frontal view, distance between lower eye lobes 0.93 times length of scape. Antennae 1.45 times elytral length with its apex reaching elytral apex at base of antennomere X. Scape with brown pubescence not obscuring integument, inner side with both white and yellow pubescence; with abundant, long, erect dark setae interspersed (more abundant ventrally). Antennomeres with brown pubescence, with long, erect, dark setae interspersed (longer ventrally), longer and more abundant on basal segments, shorter, sparser toward antennomere XI, especially dorsally; antennomere XI with abundant, short yellowish-white setae at apex. Antennal formula (ratio) based on length of antennomere III (only holotype measured): scape = 0.70; pedicel = 0.15; IV = 0.88; V = 0.40; VI = 0.37; VII = 0.35; VIII = 0.29; IX = 0.26; X = 0.22; XI = 0.28.

Thorax. Prothorax wider than long (including lateral tubercles); sides with large, conical tubercle slightly after middle, with apex blunt. Pronotum coarsely, abundantly punctate; with three longitudinal yellow pubescent bands, from base to apex, narrowest one placed centrally, another, much wider on each side; lateral yellow pubescent bands with white pubescence adjacent to it, especially on outer side; remaining surface with a few short, decumbent white setae posteriorly, and a few short, decumbent, both yellowish-white and brown setae anteriorly; with long, erect brown setae interspersed. Sides of prothorax with sculpturing as on pronotum; with white pubescence toward pronotum, distinctly not obscuring integument, and more abundant yellow pubescence, interspersed with white pubescence toward prosternum; with long, erect dark setae interspersed. Prosternum with yellowish-white pubescence (whiter depending on light intensity), not obscuring integument, on wide central area, yellower, slightly denser laterally; with long, erect, sparser yellowish-white setae interspersed. Mesoventrite with yellowish-white pubescence (whiter depending on light intensity), not obscuring integument, with long, erect setae of same color interspersed. Mesanepisternum, mesepimeron, and metanepisternum with yellow pubescence partially obscuring integument. Metaventrite with large, oblique yellow pubescent band laterally; remaining surface with yellowish-white pubescence (whiter depending on light intensity), distinctly sparser centrally. Scutellum densely yellow pubescent. Elytra. Coarsely, abundantly punctate on basal half, finer, sparser toward apex; each elytron with three yellow pubescent bands, narrowest along suture, from scutellum to apex, one wider near lateral curvature, from base to apex, another, similarly wide close to epipleural margin, from near humerus to apex; central yellow pubescent band with white pubescence bordering it on basal half; remaining elytral surface with irregular, sparse white pubescent maculae; with long, erect dark setae throughout. Legs. Femora with yellow pubescence dorsally, yellowish-white (whiter depending on light intensity) on remaining surface; with long, erect yellowish-white setae interspersed. Tibiae with white pubescence, except ventral posterior 2/3 of protibia with dark brown pubescence, and dorsal and ventral distal half of mesotibiae with dense dark brown pubescence; with long, erect brownish setae interspersed.

Abdomen. Sides of ventrites with wide yellow pubescent band, and remaining surface with yellowishwhite (whiter depending on light intensity) pubescence not obscuring integument; with long, erect yellowish-white setae interspersed.

Dimensions (mm), holotype / paratype. Total length, 6.90/6.00; prothoracic length, 1.30/1.15; anterior prothoracic width, 1.25/1.10; posterior prothoracic width, 1.35/1.20; maximum prothoracic width, 1.65/1.40; humeral width, 2.00/1.75; elytral length, 4.80/4.10.

Type material. Holotype female ( FSCA, formerly ACMT), paratype female ( ACMT) from GUATEMALA, Alta Verapaz: vic. Agua Blanca (5,100’), 1.VI.1989, J.E. Wappes col.

Remarks. Eupogonius monzoni sp. nov. is similar to E. vittipennis Bates, 1885 , but differs as follows: pronotum with central yellow pubescent band; lateral tubercles of prothorax larger ( Fig. 67 ); scutellum with dense yellow pubescence; central yellow pubescent band on elytra with white pubescence bordering it; elytra with white pubescent maculae; elytra about 3.5 times pronotal length. In E. vittipennis , pronotum without central yellow pubescent band, lateral tubercles of prothorax barely evident ( Fig. 71 ), central yellow pubescent band on elytra without white pubescent border adjacent to it, scutellum not densely yellow pubescent, elytra without white pubescent maculae, and elytra about 3.5 times pronotal length. Eupogonius monzoni especially differs from E. flavocinctus Bates, 1872 , by the conspicuous lateral tubercles of the prothorax (absent in E. flavocinctus ). It differs from E. cryptus Hovore, 1989 , by the vertex without longitudinal yellow pubescent band (present in E. cryptus ), narrow yellow pubescent band on center of pronotum (distinctly wider in E. cryptus ), wider yellow pubescent band on each side of pronotum, with white pubescence bordering them (In E. cryptus , yellow pubescent band on each side of pronotum narrow and without white pubescent border adjacent to them).

Etymology. Named for a good friend of the first author, José Monzón, Guatemala City, Guatemala, in recognition of his serious interest in surveying the insect fauna of his home country. He continues to make significant finds, including numerous new species, and is to be commended for his dedication to this very important and valuable activity.
