Redescription. Female. Integument dark brown. Pubescence predominantly brownish except for pale grayish maculae, as follows: occiput, a mark behind each upper lobe of eyes; a line on the sides of pronotum and an interrupted longitudinal line in middle; each elytron with 20 rounded spots, arranged over entire surface.

Antennae reaching apices of elytra approximately at distal tip of antennomere VI. Sides of prothorax with minute obtuse protuberance. Pronotum with single transverse line of punctures near posterior margin. Apices of elytra obliquely emarginate, external angle projecting in acute tooth. Elytral surface finely and densely punctate, mainly near basal two-thirds of suture. Fifth urotergite rounded at apex; fifth urosternite transversely truncate at distal tip. Metatarsomere I as long as II+III.

Measurements (mm), female. Total length, 6.0; prothorax length, 1.0; prothorax width, 1.5; elytral length, 4.5; humeral width, 2.0.

Comments. The absence of an acute developed tubercle on the sides of the prothorax justifies the transfer to Stenolis .
