The pubescence is inconspicuous and composed of short, fine reclinate brownish-white setae. Size: Male (n = 13) 1.4 × 0.6 mm to 2.0 × 0.8 mm ; Female (n = 16) 1.6 × 0.9 mm to 2.1 × 0.8 mm . Head subquadrate, about as long as wide, moderately punctured; punctures small, round; interspaces minutely granulose; frons wide, twice as wide as width of rostrum at base, with some long whitish setae; eyes large, strongly protuberant. Rostrum short; sides subparallel, widened only slightly at apex, moderately to densely punctured; mid-dorsal 1/3 smooth, shiny. Antenna inserted near basal 1/3 of rostrum; scape and funicular segment 1 ovoglobose, subequal in length; funicular segment 1 more robust; funicular segments 2-5 narrow, oval; 3-5 subequal in length; segment 2 more clavate, slightly longer than segments 3-5; segments 6-7 subequal, short, bead-like; club abrupt; basal and middle segment subequal in length; middle segment transversely rectangular; basal segment narrowed at base; terminal segment longer than basal or middle segment, apically acuminate, apex broadly rounded. Pronotum slightly longer than wide, widest just behind middle, densely punctured; interspaces minutely granulose. Scutellum small, inconspicuous, subquadrate. Elytra about twice as long as pronotum, widest near middle; humeri simple; striae deeply impressed, subquadrate, similar throughout; intervals narrow, weakly raised, with single row of setigerous punctures; interspaces between striae with single setigerous puncture. Thoracic pleura and sterna densely set with setigerous punctures. Abdominal ventrites moderately punctured; punctures small, round, setigerous. Distribution. Specimens were collected from the Mexican states of Nuevo Leon , Tamaulipas , Veracruz and Yucatan ( Fig. 94 ). Etymology. The specific epithet is derived from the Mexican state of Tamaulipas . Comments. Temnocerus tamaulipensis is closely related to T. abdominalis . The rosy luster and less dense punctation of the head, pronotum and abdomen distinguish it from T. abdominalis . The tegminal cap piece of the aedeagus has long setae in both species ( Fig. 59 and 84 ). The aedeagus ( Fig. 84 ) has a short tapered median lobe with a truncate pedon apex. The tectum is spatulate with a narrow base. The tegminal cap piece is finger-like with a terminal cluster of long setae. Endophallic bands are very short and weakly defined. Plant association. Unknown.
