Amblyderus werneri

Adults of the species are from 3.0 to 3.9 mm (0.12 to 0.15 in) in length. They are yellowish brown to orange and tend to be consistent in their colouration. The head is triangular, and almost twice as wide as it is long. The eyes are large and oval. The head is a light yellowish brown to orange colour, with the posterior section of the head sometimes darker. The integument is indistinctly tuberculate over entire disc, with the exception of the median smooth line. The antenna is almost double the length of the head. The prothorax is only marginally wider than the base of the head. The prothorax tapers posteriorly, with the base approximately half the width of the apex. The basal portion of the prothorax is cylindrical. The pronotum disc is tuberculated, with each tubercle having a matching puncture and decumbent seta posterior to it. The anterior section of the prothorax is finely tuberculate and is covered in white to silvery erect hairs that extends towards the heads on the dorsal surface. On the prosternum, there are longer hairs that extend laterally and ventrally. Overall, the prothorax is light yellowsish brown. The elytra is suboval, with the length of the elytra almost double the size of its width. The width of the elytra is approximately 1/3 wider than the base part of the prothorax. …

A. werneri thus far has only been observed in Great Sand Dunes National Monument and in the surrounding counties, Alamosa and Saguache, in similar dune habitats in Colorado, USA.

A. werneri was named after Floyd G. Werner, an entomologist that dedicated much of his efforts on the Anthicidae beetles and first discovered that this species was undescribed by science.
