Description. Color and pubescence: Body blackish throughout with a faint rosy and brassy luster above. Pubescence inconspicuous and consisting of short fine brownish reclinate setae. Abdominal ventrites with longer more whitish setae along each side of midline. Size: Male (n = 2) 2.3 x 0.9 mm to 2.5 x 1.0 mm; Female (n = 8) 2.2 x 0.8 mm to 2.4 x 0.9 mm. Head quadrate, about as long as wide, sparsely punctured; punctures small, round; interspaces minutely granulose; frons wide, about twice as wide as rostral base; eyes large, oval, moderately protuberant. Rostrum short, about.33 times longer than head, parallel-sided; in lateral view nearly straight, apically depressed; basi-dorsal 1/2 minutely granulose as in head interspaces; sides moderately punctured; apico-dorsal 1/4 smooth, shiny. Antenna inserted at basal 1/4; scape and funicular segment 1 ovoglobose, subequal,; funicular segments 2 and 3 narrow, weakly clavate; segment 2 slightly longer than 3; segments 4-7 shorter, bead-like; segments 6 and 7 slightly more robust; club abrupt; basal and middle club segments subequal, wider than long; terminal segment smaller than basal or middle segment, rounded, bluntly acuminate. Pronotum about as long as wide, weakly constricted anteriorly, widest behind middle, very densely punctured; interspaces minutely granulose. Scutellum rectangular, slightly wider than long, minutely granulose. Elytra about twice as long as pronotum, widest just behind middle; humeri simple; striae subquadrate, deeply impressed, similar in size throughout; intervals narrow, raised, with single row of setigerous punctures; strial interspaces with single setigerous puncture. Thoracic pleura and sterna densely with moderate to dense coarse setigerous punctures. Adominal ventrites distinctly concave, with sparse, small, setigerous punctures; punctures along each side of midline with longer more numerous setae; lateral interspaces minutely granulose.
Distribution. A widespread species with adults recorded from central Mexico south into Guatemala and Honduras ( Fig. 92 View Figure 91-94 ).
Comments. The adults of this species can be recognized by the rostrum that is nearly straight, parallelsided, distinctly depressed apically (“needle nosed”) and with minute granulations in the dorso-basal half. The pronotum is very densely punctured and weakly constricted anteriorly. The aedeagus ( Fig.75 View Figure 59-86 ) has a short apically tapered median lobe with the pedon apex sharply truncate. The tectum is spearheadshaped. The tegminal cap piece is finger-like and the knob-like pigmented apex bears a cluster of setae. Endophallic bands are linear, pigmented and elongate. The aedeagus of this species shows affinities with those of T. potosi and T. pseudaeratus ( Fig. 76 and 77 View Figure 59-86 ).
Plant association. A single female specimen is recorded from Quercus sp. in the Mexican state of Guerrero.
