Acmaeodera conoidea
Acmaeodera conoidea is a small metallic wood-boring beetle in the family Buprestidae, described by Fall in 1899. It belongs to the 'tubulus-species group' within the genus, characterized by small size (<8 mm), black coloration with yellow maculations on the elytra, and membership in the 'Truncatae' group (species with prosternal margin nearly straight). The species occurs in the south-central and southwestern United States. Like other members of its species group, it is difficult to identify without comparison to determined specimens due to the lack of modern revisionary work on the genus.
Acmaeodera neoneglecta
Acmaeodera neoneglecta is a small metallic wood-boring beetle in the family Buprestidae, first described by Fisher in 1949. It belongs to the 'tubulus-species group' within the genus, characterized by small size (<8 mm), black coloration with yellow maculations on the elytra, and membership in the 'Truncatae' group (prosternal margin nearly straight). The species occurs in the southwestern United States and northern Mexico, where adults have been collected from flowers of various plants including cacti and herbaceous species.
Acmaeodera quadriseriata
Acmaeodera quadriseriata is a jewel beetle (family Buprestidae) described by Fall in 1899. It belongs to the large North American genus Acmaeodera, which contains approximately 150 species and is in need of taxonomic revision. The species is part of the morphologically similar 'tubulus-species group' characterized by small size (<8 mm), black coloration with yellow elytral maculations, and membership in the 'Truncatae' group. Identification of this and related species is difficult due to inadequate original descriptions and lack of modern identification keys.
Acmaeodera sabinae
Acmaeodera sabinae is a small jewel beetle species described by Knull in 1937. It belongs to the A. tubulus-species group, characterized by small size (under 8 mm), black coloration with confused yellow maculations on the elytra, and membership in the 'Truncatae' group of the genus. Like other members of this group, it lacks a subapical crest on the last ventral segment. The species is one of eight described since Fall's 1899 revision of the genus, contributing to the taxonomic complexity of this difficult group that now contains over 150 species in North America.
