Anurophorinae
Anurophorinae is a subfamily of springtails (Collembola) within the family Isotomidae, established by Börner in 1901. Members of this subfamily are characterized by the absence of a furcula (springing organ), a trait reflected in the name 'Anurophorinae' (meaning 'tailless'). These small hexapods are part of the diverse soil and leaf litter fauna, contributing to decomposition processes. The subfamily is moderately well-represented in global collections with over 1,100 iNaturalist observations recorded.
Lophognathella
Lophognathella is a genus of springtails in the family Onychiuridae, subfamily Lophognathellinae. These small, wingless hexapods are part of the euedaphic soil fauna, living primarily in deep soil layers. The genus was established by Börner in 1908 and is distributed across northern North America, the Pacific coast of North America, and the Sino-Japanese region. As members of the Onychiuridae, they lack a furcula (springing organ) and are characterized by reduced eyes and elongated mouthparts adapted for feeding in soil micropores.
