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.

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.
