Abstract
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.
描述了同一地点（墨西哥瓜达拉哈拉）的两个 Aulacoscelis 新种：A. caroli n. sp：caroli n. sp.和 A. nahuatl n. sp.与 A. grandis Jacoby 一起组成了一个类群，其特征是背甲颜色完全为光谱橙色，头部、胸部（至少 A. grandis 的大部分为黑色）、腿部和腹部发亮。caroli n. sp.的特征是体型相对较小，前胸光滑，前胸两侧从近中段开始下部具深波状，胫骨平直，前胸先端平直且变尖。A. nahuatl n. sp. 的特征是体型相对较大，前胸表面不规则，前胸两侧基部平直，中胫弯曲，趾甲先端呈凹陷状。
