Acmaeodera pubiventris yumae
Acmaeodera pubiventris yumae is a subspecies of jewel beetle in the family Buprestidae, described by Knull in 1937. It belongs to the nominate subgenus Acmaeodera (s. str.) and is part of a species complex associated with woody host plants in western North America. The subspecies epithet "yumae" suggests a connection to the Yuma region, though precise type locality details are not provided in available sources. Like other members of Acmaeodera, adults are likely active during warmer months and associated with flowers or host plant foliage.
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.
Obrium glabrum
Obrium glabrum is a species of longhorned beetle in the family Cerambycidae, described by Josef N. Knull in 1937. It belongs to the tribe Obriini within the subfamily Cerambycinae. The species epithet "glabrum" (Latin for "smooth") suggests a relatively hairless or smooth-bodied appearance compared to congeners. Very little specific biological information has been published for this species.
Paratyndaris acaciae
Paratyndaris acaciae is a species of metallic wood-boring beetle in the family Buprestidae. It belongs to the subgenus Paratyndaris (Paratyndaris) within the genus Paratyndaris. The species is found in Central America and North America, with the specific epithet suggesting an association with Acacia host plants. Like other members of the genus, it is associated with woody leguminous plants and is typically collected by beating dead or dying branches.
Paratyndaris albofasciata
Paratyndaris albofasciata is a metallic wood-boring beetle in the family Buprestidae, first described by Knull in 1937. It belongs to the subgenus Paratyndaris (Paratyndaris) within the genus Paratyndaris. The species is known from Central America and North America, though specific biological details remain poorly documented in the accessible literature.
