Kelypitnus Coleoptera Ptinidae new genus Madagascar Bostrichoidea endemic


A new endemic Madagascan genus and species of spider beetle from Toliara Province in southwest Madagascar is described. The genus Kelypitnus gen. nov. is characterized by its small size and dark brownish-black color, a short lateral margin on the pronotum, a concave proventrite, 10-segmented antennae, and the presence of a small, conspicuous raised ring with a central cavity on the first abdominal ventrite in the male. The single species, Kelypitnus steineri sp. nov. is diagnosed, described, and illustrated and compared to the two most similar genera known, Neoptinus Gahan and Pitnus Gorham.
