nivalis (Fleutiaux & Germain) in size, differing in having the integument pale yellow, including the head; reduced elytral maculae; dorsal sculpture finer in diameter and depth, with the pronotal and elytral punctures larger and the interpunctural spaces wider, 1.0-1.3 time their own diameter; the frontal margin finely carinate and lacking a narrow submarginal impression; and the aedeagal parameres shouldered and attenuate, with a long apical seta each (Fig.

Diagnosis: Shell small to large size; anterior end weakly carinate; dorsum smooth; spire of medium height and partially exposed; aperture wide, sides rounded; anterior and posterior canals deep; fossula smooth, concave, wide.
Pronotum subquadrate with anterior angles rounded, dorsum slightly convex, surface even, median lobe slightly impressed medially, posterior angles slightly acute, lateral margin acute, carinate posteriorly to the middle, ampliate in the middle, obsolete anteriorly; cervical sulcus moderately deep, extending from near coxal cavity to about 0.66 to 0.76 distance to pronotal midline; pronotal disk microfoveolate; propleura glabrous and finely striate; prosternum acute at apex, separating the procoxae for about one half their length.
Head: face mostly acinose with central area slightly swollen and rugose; frons acinose and carinate near toruli, vertex and temple acinose (Figure 2); oral opening small, diameter about 0.7 times the malar space; malar space 0.56 times eye height (Figure 3); frons slightly excavated; occipital carina meeting hypostomal carina; ocello-ocular distance about 4.0 times diameter of the lateral ocellus (Figure 4); 32 antennomeres.
