Agathon
Agathon is a genus of net-winged midges in the family Blephariceridae, established by Röder in 1890. These aquatic Diptera are characterized by their distinctive wing venation and are typically found in fast-flowing mountain streams. The genus has a broad distribution across the Holarctic and Oriental regions.
Chloroperlini
green stoneflies
Chloroperlini is a tribe of green stoneflies within the family Chloroperlidae. Members are characterized by their predominantly green coloration as adults and are associated with lotic freshwater habitats. The tribe contains multiple genera distributed across the Northern Hemisphere. Larvae are aquatic and typically found in cool, well-oxygenated streams.
Dicrotendipes
non-biting midges
Dicrotendipes is a globally distributed genus of non-biting midges in the family Chironomidae. The genus was established by Kieffer in 1913 and contains approximately 25 described species. Larvae of some species have been documented from lotic (flowing water) habitats in Australia, where they exhibit distinctive morphological features including unique arrangements of ventral tubules and characteristic head capsule pigmentation.
Diplectrona
diplectronan caddisflies
Diplectrona is a genus of net-spinning caddisflies in the family Hydropsychidae, containing over 100 described species distributed across multiple continents. The genus exhibits considerable morphological diversity in both larvae and adults, with larvae inhabiting various lotic freshwater habitats. Recent studies have revealed cryptic diversity within currently recognized species, particularly in North America, suggesting the genus requires taxonomic revision. Species occur in Asia, Europe, North America, and other regions, with new country records continuing to be documented.
Dixa
Dixa is a genus of non-biting midges in the family Dixidae, established by Johann Wilhelm Meigen in 1818. The genus has cosmopolitan distribution, with species recorded across Europe, North America, and other regions. Species-level taxonomy within Dixa has been subject to recent revision, with several new species described from North America and taxonomic confusion resolved for historically problematic names such as D. modesta. Larvae develop in aquatic environments, particularly lotic (flowing water) habitats.
Ecdyonurus
Ecdyonurus is a genus of mayflies in the family Heptageniidae, comprising approximately 66 described species distributed primarily across Europe and parts of North Africa and Asia. The genus is taxonomically well-studied, with multiple species described in recent decades from mountain regions including the Carpathians, Crimean Peninsula, and Aurès Mountains. Species within this genus are typically associated with running waters and have been subjects of ecological studies on larval growth and thermal biology.
Protanypus
Protanypus is a genus of non-biting midges in the subfamily Diamesinae of the family Chironomidae. The genus comprises approximately 10 described species distributed across Europe, North America, and Asia. Species within this genus are found in aquatic environments, with larvae inhabiting freshwater habitats. The genus was established by Kieffer in 1906.
Psepheninae
water-penny beetles
Psepheninae is a subfamily of Psephenidae (Coleoptera: Polyphaga) containing water-penny beetles, named for the distinctive flattened, oval larvae that resemble pennies. The subfamily includes at least six genera: Psephenus, Psephenops, Pheneps, Psephenotarsis, Psephenopalpus, and Belicinus. Members are strictly aquatic and occur in the New World from North America through Central America to South America.
Shipsa rotunda
Intrepid Forestfly
Shipsa rotunda is a Nearctic stonefly species in the family Nemouridae with an extensive distribution across Canada and the United States. Despite its wide geographic range, the species exhibits remarkably little morphological variation in both males and females. Reproductive terminalia have been examined using scanning electron microscopy from specimens across its range, revealing consistent structural features. The species was originally described as Nemoura rotunda by Claassen in 1923 and later transferred to the genus Shipsa.
