Apiloscatopse uncinata
A small, poorly known scatopsid fly described from North America. The genus name Apiloscatopse indicates a hairless or sparsely pilose condition relative to other scatopsids. The specific epithet uncinata (Latin for 'hooked') likely refers to some hooked structure, though the original description has not been examined. The species was described by Melander in 1916 and remains rarely encountered in collections or literature.
Rhegmoclemina
Rhegmoclemina is a genus of minute black scavenger flies (Diptera: Scatopsidae) established by Enderlein in 1936. It belongs to the tribe Rhegmoclematini within the subfamily Scatopsinae. The genus is poorly documented in scientific literature, with minimal species-level descriptions and ecological data available. Records indicate presence in Norway and Sweden.
Tanyderidae
Primitive crane flies
Tanyderidae, commonly called primitive crane flies, are a small family of long, delicate nematoceran flies with about 40 extant species. They represent a relict lineage within Diptera, retaining primitive wing venation including five complete branches of the radial vein. Adults are recognized by their spotted or mottled wings and are typically found near streams, often resting on vegetation or hanging beneath bridges. Larvae inhabit wet, decaying wood or sandy and gravelly stream margins. The family has an extensive fossil record dating to the Late Triassic, with numerous extinct genera known from amber deposits.
