Allonychiurus flavescens
Allonychiurus flavescens is a species of springtail in the family Onychiuridae. It is a small, soil-dwelling hexapod found in Pacific North American and Sino-Japanese regions. As an euedaphic collembolan, it lives deep within soil profiles and lacks a furcula (springing organ) typical of surface-dwelling springtails. The species was described by Kinoshita in 1916.
Heteraphorura
Heteraphorura is a genus of springtails in the family Onychiuridae, first described by Bagnall in 1948. As a member of the tribe Hymenaphorurini, it belongs to a group of euedaphic (deep soil-dwelling) Collembola characterized by reduced or absent eyes and elongated body forms. The genus has been recorded across multiple continents including Europe, Mediterranean regions, northern Eurasia, and parts of North America.
Hymenaphorura
Hymenaphorura is a genus of springtails (Collembola) in the family Onychiuridae, established by Bagnall in 1948. Members of this genus are eyeless, euedaphic (soil-dwelling) or troglobitic (cave-dwelling) species with reduced pigmentation. The genus has been recorded from caves and subterranean habitats across Europe, with some species showing narrow endemic distributions restricted to single cave systems.
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.
Lophognathella choreutes
Lophognathella choreutes is a species of springtail in the family Onychiuridae, first described by Carl Börner in 1908. It belongs to the subfamily Lophognathellinae, a group of euedaphic (deep soil-dwelling) springtails characterized by reduced or absent eyes and elongated mouthparts. The species has been recorded across northern North America, Pacific North America, and the Sino-Japanese region. As with other members of Onychiuridae, it inhabits soil and leaf litter environments where it contributes to decomposition processes.
Onychiurinae
Onychiurinae is a subfamily of springtails (Collembola) in the family Onychiuridae, established by Börner in 1901. Members are characterized by reduced or absent eyes and the presence of a ventral tube (collophore) with distinct structures. The subfamily is primarily soil-dwelling and includes numerous genera distributed across temperate regions. Many species are blind and adapted to subterranean or deep soil habitats.
Onychiuroidea
Onychiuroidea is a superfamily of springtails (Collembola) within the order Poduromorpha. It comprises approximately five families and over 630 described species. The superfamily includes the well-known family Onychiuridae and several smaller families whose classification has been subject to revision. Members of this group are soil-dwelling hexapods characterized by reduced or absent furcula (springing organ).
