Type locality. Municipio San Joaquín, Campo Alegre, 20°54′47″N, 099°34′35″W, Estado de Querétaro, Mexico.

Type repository. Florida State Collection of Arthropods, Gainesville, Florida, U.S.A.

Description. Length 4.5–5.0 mm, elongate, moderately convex, shiny, glabrous. Piceous; clypeal margin, pronotal sides, juxtasutural interstriae and apical margins of elytra reddish-brown; legs reddish; antennal club piceous. Head with epistome moderately gibbous, somewhat irregularly, rather densely coarsely punctured; punctation distally confusedly subrugose; clypeus moderately angulately sinuate at middle, denticulate at sides, rather thickly bordered, the edge feebly upturned; genae obtusely round, sparsely elongately ciliate, protruding from the eyes; frontal suture almost obsolete; front coarsely subregularly punctured. Pronotum transverse, moderately convex, dually punctured; large punctures, three to four times larger than small ones, denser and coarser on sides, sparse and almost lacking on disc; small punctures dense and coarse on sides, fine and sparse on disc; lateral margins feebly arcu- ate, rather thickly bordered; hind angles obtusely round; base not bisinuate, finely bordered. Scutellum with few punctures on basal third. Elytra oblong, convex, not denticulate at shoulder, finely striate; striae superficially punctured, not crenulate; interstriae almost flat, distinctly sparsely punctured. Hind tibiae upper spur as long as first tarsal segment; latter as long as following three segments combined. Male: fore tibiae spur digitiform, as long as first three tarsal segments; aedeagus Fig. 49–50 . Female: fore tibiae spur almost regularly acuminate, feebly curved and as long as first two tarsal segments.

Distribution. Mexico ( México, Querétaro).

Etymology. The name results from the combination of the Mexican vernacular name “tuza” used for several species of rodents and the Latin suffix “incola” [= inhabitant], and is here considered masculine in gender.

Biology. Specimens were collected sifting materials found in nests of rodents.
