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

( Fig. 55–58 )

Description. Female. Integument mostly dark brown, almost black on some areas; anteclypeus reddish-brown; apex of palpomeres and most of tarsomeres V reddish-brown; apex of antennomere XI yellowish-brown.

Head. Frons finely, abundantly punctate; with light yellowish-brown pubescence partially obscuring integument and long, erect, abundant setae of same color (some of them brownish toward their apex). Vertex and area behind eyes with sculpturing as on frons, except smooth area close to prothoracic margin behind lower eye lobes; pubescence as on frons, smooth area behind lower eye lobes glabrous; with long, erect, both brown and yellowish setae interspersed on vertex, only yellowish behind eyes. Genae distinctly shorter than lower eye lobe; finely, sparsely punctate (punctures finer than on frons toward clypeus, and as on frons toward ventral surface); with light yellowish-brown pubescence not obscuring integument, especially toward clypeus, with a few long, erect yellowish setae interspersed toward ventral surface. Antennal tubercles with sculpturing, pubescence and erect setae as on frons. Distance between upper eye lobes 0.53 times length of scape; in frontal view, distance between lower eye lobes 1.06 times length of scape. Antennae 1.15 times elytral length, reaching elytral apex at posterior quarter of antennomere IX. Scape slightly widened from base to anterior third, nearly parallel-sided toward apex; with white pubescence not obscuring integument (slightly yellowish basally), with long, erect, both brown and yellowish setae interspersed (brown setae more abundant dorsally and yellowish more abundant ventrally). Antennomeres III–IV with white pubescence on anterior 2/3, not obscuring integument, brown on posterior third, with long, erect brown setae interspersed throughout. Antennomeres V–XI with basal white pubescent ring, and brown pubescence on remaining surface; V–X with long, erect brown setae ventrally, and long, erect setae on dorsal apex (shorter than on ventral area); antennomere XI with yellowish setae. Antennal formula (ratio) based on length of antennomere III: scape = 0.70; pedicel = 0.19; IV = 1.03; V = 0.54; VI = 0.51; VII = 0.52; VIII = 0.46; IX = 0.42; X = 0.36; XI = 0.34.

Thorax. Prothorax wider than long (including lateral tubercles); each side bearing a large conical tubercle with distinctly rounded apex. Pronotum coarsely, abundantly punctate; with light yellowishbrown pubescence, forming a vague M-shaped pubescent band on posterior half (central arm denser and more yellowish), pubescence slightly sparser on remaining surface, except denser, narrow, longitudinal central band on anterior third; with long, erect brown setae interspersed throughout. Sides of prothorax with sculpturing as on pronotum; with light yellowish-brown pubescence partially obscuring integument, with long, erect setae of same color interspersed. Prosternum coarsely, sparsely punctate on posterior 3/4, nearly impunctate on anterior quarter; with light yellowish-brown pubescence (more yellowish depending on light intensity), not obscuring integument, sparser on anterior sulcus, with long, erect yellowish setae interspersed. Ventral surface of meso- and metathorax with light yellowish-brown pubescence, denser laterally, sparser centrally, especially on mesoventrite; with long, erect yellowish setae interspersed. Scutellum with dense yellow pubescence. Elytra. Coarsely, abundantly punctate on anterior 2/3, finer, sparser on posterior third; with abundant light yellowish-brown pubescence, not obscuring integument, with large, irregular yellowish-white pubescent maculae interspersed (whiter depending on light intensity), with long, erect, both brown and yellowish setae interspersed. Legs. Femora with light yellowish-brown pubescence partially obscuring integument on some areas, with long, erect yellowish setae interspersed. Tibiae with light yellowish-brown pubescence not obscuring integument (more yellowish depending on light intensity), except dorsal posterior third of mesotibiae with denser yellow pubescence, with long, erect, abundant yellowish setae intermixed with the pubescence.

Abdomen. Ventrites with abundant light yellowish-brown pubescence (more yellowish-white on some ventrites, depending on light intensity), with margin of apex I densely fringed with darker yellowishbrown pubescence; with long, erect yellowish setae interspersed.

Dimensions (mm). Total length, 8.20; prothoracic length, 1.65; anterior prothoracic width, 1.55; posterior prothoracic width, 1.60; maximum prothoracic width, 2.05; humeral width, 2.40; elytral length, 5.70.

Type material. Holotype female from MEXICO, Guerrero: Hwy 134, 55 km NE junction with Hwy 200, 15.VII.1985, J.E. Wappes col. ( FSCA, formerly ACMT).

Remarks. Eupogonius boteroi sp. nov. is similar to E. guerrerensis sp. nov. but differs as follows: distance between upper eye lobes distinctly greater; elytra with irregularly distributed yellowish-white pubescent maculae; apex of the lateral tubercles of the prothorax distinctly rounded. In E. guerrerensis the distance between upper eye lobes is distinctly less, the elytra lack yellowish-white pubescent maculae, and the apex of the lateral tubercles of the prothorax is acute. Although the distance between upper eye lobes is greater in females than in males of some species, it is never as great as the difference between E. boteroi and E. guerrerensis .

Etymology. Named to recognize Juan Pablo Botero, postdoctoral in the MZSP, for his friendship and enthusiasm for the study of Cerambycidae .
