Cymatodera aegra-complex
checkered beetle
The Cymatodera aegra-complex comprises a group of checkered beetles in the family Cleridae, subfamily Tillinae. These beetles are known from the southwestern United States and northern Mexico, where they have been collected in association with desert thorn-scrub vegetation. Members of this complex are morphologically similar and may represent a cryptic species assemblage requiring further taxonomic study.
Cymatodera angustata
Cymatodera angustata is a species of checkered beetle in the family Cleridae. The species was described by Spinola in 1844 and occurs in Central America and North America. As a member of the genus Cymatodera, it belongs to a group of clerid beetles commonly associated with predatory habits on other insects, though species-specific biology for C. angustata remains poorly documented.
Tillinae
checkered beetles (subfamily)
Tillinae is a subfamily of checkered beetles (family Cleridae) comprising approximately 164 described species across 11 genera in the New World. The subfamily is characterized by diagnostic morphological features including procryptosternum fused to pronotal extension, closed procoxal cavities, and 5-5-5 tarsal formula. Body size ranges from 3 to 40 mm. The genus Cymatodera dominates the subfamily with approximately 134 species, exhibiting its greatest diversity in Mexico.
