Anthaxia dichroa
Anthaxia dichroa is a metallic wood-boring beetle (family Buprestidae) described by Bílý in 1991. It is found in North America and has been documented in ethanol-only bait traps in Illinois, where it occurs alongside related Anthaxia species. The genus Anthaxia includes species associated with Cercocarpus (mountain mahogany) and other woody hosts, though specific host relationships for A. dichroa remain unconfirmed.
Dorithia trigonana
Dorithia trigonana is a small tortricid moth described by Brown & Obraztsov in 1991. The species is known from a limited geographic range spanning southern Arizona and the state of Durango in Mexico. Adults have a wingspan of 19–21 mm. It belongs to the tribe Cochylini within the subfamily Tortricinae.
Geopsammodius relictillus
relictual tiny sand-loving scarab
Geopsammodius relictillus is a small aphodiine dung beetle in the family Scarabaeidae, described from Florida in 1991. The species epithet "relictillus" refers to its relictual status, suggesting it may represent a remnant population of a formerly more widespread group. It belongs to the tribe Psammodiini, whose members are commonly known as sand-loving scarabs due to their association with sandy habitats.
Ischnosoma suteri
Ischnosoma suteri is a rove beetle described in 1991 from eastern North America. It belongs to the genus Ischnosoma, which was separated from Mycetoporus based on morphological characters including mouthpart structure and abdominal chaetotaxy. The species is part of a 1991 revision that established Ischnosoma as a distinct genus in the Tachyporinae subfamily.
