Arrhopalites
springtails
Arrhopalites is a genus of globular springtails (Collembola: Symphypleona) in the family Arrhopalitidae. The genus comprises approximately 40 valid species, with roughly half considered troglobionts—obligate cave-dwelling organisms. Species occur across diverse habitats including cave systems, forest leaf litter, and soil environments, with distribution spanning the Neotropical Region, Asia, Europe, and other regions. The genus is taxonomically significant for phylogenetic studies of Symphypleona, though many aspects of its biology remain understudied.
Arrhopalites diversus
Arrhopalites diversus is a species of globular springtail in the family Arrhopalitidae, described by H.B. Mills in 1934. It belongs to the order Symphypleona, characterized by a rounded, globular body form. The species has been recorded from multiple regions across North America and the Caribbean. Like other members of its family, it inhabits soil and leaf litter environments.
Pygmarrhopalites
A genus of springtails (Collembola: Symphypleona) in the family Arrhopalitidae. The genus was established by Vargovitsh in 2009. Multiple species have been described, including both epigean and troglobiont (cave-dwelling) forms. Some species exhibit troglomorphies including reduced pigmentation, elongated appendages, and modified foot complex.
