Authors

Two new species of Aulacoscelis are described from the same locality (Guadalajara, Mexico): A. caroli n. sp. and A. nahuatl n. sp. With A. grandis Jacoby they form a group of taxa characteristic in the elytra completely spectrum orange in color, with shiny black head, thorax (at least in large part for A. grandis), legs and ventral parts. A. caroli n. sp. is characterized by a relatively small size, smooth pronotum, sides of pronotum sinuate proximally starting from nearly mid length, straight tibiae, straight and sharpened apex of aedeagus. A. nahuatl n. sp. is characterized by a relatively large size, with irregular surface of pronotum, sides of pronotum straight in their basal half, bent mesotibiae and sinuate apex of aedeagus.
