Acidocerinae
Acidocerinae is a cosmopolitan subfamily of water scavenger beetles (Hydrophilidae) containing over 500 species in 23-24 genera, making it one of the largest and most morphologically heterogeneous lineages in the family. The subfamily occupies a key phylogenetic position as sister to the largely terrestrial Cylominae+Sphaeridiinae clade. Recent taxonomic revisions (2013, 2021) have substantially restructured generic boundaries, establishing new genera such as Colossochares, Novochares, Aulonochares, Ephydrolithus, and Primocerus while synonymizing former subgenera of Helochares.
Ithycerus noveboracensis
New York Weevil
Ithycerus noveboracensis is a primitive weevil and the sole living member of the family Ithyceridae. It is among the largest North American weevils, measuring 12–18 mm. The species is characterized by its distinctive spotted coloration and bristly body texture. It occurs in deciduous forests of eastern North America, where adults feed on fungi and sap flows from hardwood trees.
Tischerioidea
Trumpet Leafminer Moths, Trumpet Leaf Miner Moths
A monobasic superfamily of minute moths containing a single family, Tischeriidae. Larvae are leaf miners that produce distinctive trumpet-shaped mines in host plant foliage. The group holds phylogenetic significance as a candidate sister taxon to the Ditrysia, the largest clade of Lepidoptera. Females possess a monotrysian reproductive system, a plesiomorphic trait shared with other basal lepidopteran lineages.
