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 mmto 2.5 x 1.0 mm; Female (n = 8) 2.2 x 0.8 mmto 2.4 x 0.9 mm. Headquadrate, 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. Rostrumshort, 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. Antennainserted 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. Pronotumabout as long as wide, weakly constricted anteriorly, widest behind middle, very densely punctured; interspaces minutely granulose. Scutellumrectangular, slightly wider than long, minutely granulose. Elytraabout 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 sternadensely with moderate to dense coarse setigerous punctures. Adominal ventritesdistinctly 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 Mexicosouth into Guatemalaand Honduras( Fig. 92).
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) 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. potosiand T. pseudaeratus( Fig. 76 and 77). Plant association.A single female specimen is recorded from Quercussp.in the Mexican state of Guerrero.
