Description. Holotype male ( Fig. 45a ). Length 11.8 mm; width 6.5 mm. Color: Dorsal surface tomentous. Pronotum yellowish brown with 2 longitudinal, black vittae on each side of midline, 1 small, dark, semicircular, anterolateral mark at each side. Elytra yellowish brown, with black, moderately sized, irregular, markings. Ventral surface, including legs, dark brown. Head: Frons densely punctate; punctures deep, moderate in length, many confluent, moderately densely setose; setae yellowish, moderate in size. Clypeus subrectangular, laterally expanded anteriorly in dorsal view, lateral margins moderately raised; apex weakly raised, moderately sinuate; punctation as on frons, sparsely setose; setae yellowish, short to moderate. Antennal club longer than stem. Pronotum: Surface moderately densely punctate; punctures round to lunulate, small, denser and larger toward apex. Surface moderately densely setose; setae short to moderate, yellowish. Sides moderately angulate. Base in front of scutellum weakly emarginate. Scutellum impunctate, apex sharp. Elytra: Surface moderately densely punctate, striae bearing 2, lateral rows of moderately dense punctures, and 1 sparsely punctate medial row, punctures small to moderate, lunulate to irregular, sparsely setose; setae short to moderate, yellowish. Pygidium: Surface subconcentrically striate; striae dense, discontinuous, moderately densely setose, setae short to moderate. Apex evenly rounded. Legs: Protibiae slender, teeth sharp, equidistant, strongly oblique. Meso and metatibial carinae moderately developed. Metatibiae not strongly expanded apically, metatarsi longer than metatibiae. Venter: Mesometasternal process moderately compressed laterally, apex rounded, extended extended to same level as mesocoxae. Mesepimera, metasternum, metepimera, and metacoxae setose; setae as on legs. Metasternum rugose, densely setose laterally, weakly punctate and setose at middle, median sulcus strongly impressed. Abdomen in lateral view flat.

Allotype. Female. Similar to holotype except in the following: Length 12.0 mm; width 7.0 mm. Head: Frons glabrous. Clypeus glabrous, apex vaguely reflexed. Antennal club shorter than stem. Pygidium: Apex slightly pointed. Legs: Metatibiae moderately expanded apically, metatarsi shorter than metatibiae.Abdomen in lateral view strongly convex.

Variation. Paratypes (24) similar to the holotype and allotype except in the following: Length 9.9–13.1 mm; width 5.6–7.3 mm. Color: Melanistic forms present. Head: Frons weakly to moderately setose. Pronotum: Base in front of scutellum weakly to moderately emarginate. Legs: Protibiae slender in males, robust in females, apical and medial teeth frequently proximal in males, basal tooth frequently obsolete to subobsolete in males, teeth frequently equidistant and well developed in females. Meso- and metatibial carinae weakly to moderately developed in males, moderately to strongly developed in females. Male genitalia: Parameres as in Fig. 45c .

Diagnosis. This species is separated from other species in the group by the following combination of characters: antennal club longer than stem in males; clypeus subrectangular; elytral striae without grooves; protibial teeth strongly oblique; and form of the parameres.

Temporal Distribution. June (2), August (9), September (3), October (12) ( Fig. 45d ).

Geographic Distribution. Known from Guerrero, Oaxaca, and Chiapas, Mexico ( Fig. 45e ).

Etymology. The name is derived from the feminine Spanish diminutive form of “Mayan”.
