Description. Color and pubescence: Body blackish throughout with a faint brassy luster. Pubescence inconspicuous, composed of short, fine, reclinate, whitish-brown setae. Size: Male (n = 10) 1.7 × 0.7 mm to 1.9 × 0.8 mm; Female (n = 5) 2.0 × 0.7 mm to 2.2 × 0.9 mm. Head quadrate, densely punctured; punctures large; interspaces minutely granulose; frons wide, almost twice as wide as width at rostral base; eyes large, oval, moderately protuberant. Rostrum short, only slightly longer than head, with sparse to moderate lateral punctures; dorsal base with weak longitudinal strigae; dorsal 1/2 smooth, shiny, with lateral punctures; apex distinctly widened to width subequal to width of frons; in lateral view slightly arcuate and slightly flattened apically. Antenna longer than rostrum, inserted just behind basal 1/3 of rostrum; scape and funicular segment 1 ovoglobose, subequal; funicular segments 2-4 narrow, oval, subequal; segments 5-7 subequal, short, bead-like; club large, abrupt; basal segment and middle segment subequal in length; basal segment narrowed to base; terminal segment longer than middle or basal segment, acuminate and broadly rounded at apex. Pronotum slightly wider than long, widest just behind middle, densely set with large punctures like those of head; interspaces minutely granulose. Scutellum small, rectangular, wider than long. Elytra elongate, more than twice as long as pronotum; widest just behind middle; humeri simple; striae subquadrate, deeply impressed, similar throughout; intervals narrow, raised, with single row of setigerous punctures; interspaces between striae with single setigerous puncture. Thoracic pleura and sterna with dense, coarse, setigerous punctures. Abdominal ventrites sparsely set with small punctures; lateral interspaces minutely strigate.

Distribution. All specimens of the type material are from the Mexican state of Puebla (fig 93).

Etymology. The specific epithet is derived from the Mexican state of Puebla.

Comments. Adults are small and blackish with a brassy luster above. The rostrum in both sexes is relatively short, wide and dorso-basally strigate ( Fig. 41, 42). The dorsal rostral apex is smooth and shiny and distinctly widened to a width sub-equal to the width of the frons. The pronotum is wider than long and densely punctured. The aedeagus ( Fig.78) has a short wide median lobe with the pedon

blade-like and pointed. The tectum is spatulate with the apex broadly rounded. The tegminal cap piece is finger-like with the pigmented apex bearing a cluster of setae with a somewhat longer medial pair. Endophallic bands are short, linear and distinct.

Plant association. Unknown.
