). However this species can be diagnosed from all others by the presence of extra setae on the pronotum. In addition to the large setae homologized with the lateral pronotal setae, there are 9-11 smaller setae in the marginal depression anterad the lateral seta, and 4-5 setae in the depression behind the lateral seta. The prosternum also bears a sparse pelage of elongate setae, with the anterior surfaces of the femora also so covered. The elytral striae are totally reduced in this species, and the cuticular microsculpture also totally absent from head capsule, pronotum, elytra, and ventrites. Standardized body length 4.7-5.1 mm. Chaetotaxy +/+//2+11/-5//+/2/+/+, signifying that the lateral pronotal seta has been doubled, with up to 11 microsetae lining the lateral marginal depression anterad those setae. Also, though the basal pronotal seta is absent, up to 5 microsetae lie along the lateral margin near the pronotal base. The two lateral pronotal setae are longer and stouter than the anterior 11 and posterior 5 microsetae, supporting homology of the double setae with the single lateral pronotal seta of the other species, and the autapomorphic status of the numerous and variable microsetae.
