Alaudes setigera

Diagnosis
Lateral aspect of pronotum with short, clavate setae. Elytral setae slender and hair-like throughout, occasionally varying to feebly clavate-lanceolate, especially toward the sides and apex (Fig. 9C); setae uniform in length, vestiture always muchlonger than twice width,length of longest setae equal to or shorter than apical two antennomeres combined; punctures deep, well defined, distance between punctures about equal to size of puncture. Parameres (Fig. 2B) longer than basal piece; basal piece slightly broader than parameres, curved basally. Parameres gradually curved basally.
