“…Although poor compared to Europe, the diversity of South Africa Collembola is increasingly better understood due to international collaborations since 2008 (Janion et al 2011a(Janion et al , b, 2012Janion-Scheepers et al 2013, 2015Potapov et al 2011). The family Isotomidae, which include the dominant Collembola in soil and moss habitats of South Africa, has been particularly little studied, and currently consists of 19 confirmed described species (Janion-Scheepers et al 2015).…”

Species of the genera of the Cryptopygus complex in South Africa are morphologically revised. Five new species of the genus Cryptopygus Willem, 1902 s. s. and one new species of the genus Isotominella Delamare Deboutteville, 1948 are described. Cryptopygus abulbussp. nov. and C. bulbussp. nov. have only one chaeta on the anterior side of dens and no chaetae on the anterior side of manubrium, the latter species being characterized by the presence of a bulb at apex of antennae; C. inflatussp. nov. shows a rare combination of eight ocelli on each side of the head with a tridentate mucro; C. longisensillussp. nov. has five long s-chaetae on the fifth abdominal segment; C. postantennalissp. nov. is unique by having a very long and slender postantennal organ with strong inner denticles; Isotominella laterochaetasp. nov. is the second member of the genus and differs from the type species by many more anterior chaetae on the manubrium and the presence of chaetae on ventral side of metathorax. The genera are discussed and a key to all species of the Cryptopygus complex recorded in South Africa is given. The focus is on the Western Cape Province where the complex is the most diverse and sampling more complete than in other provinces of South Africa.

“…Haplotype screening for this species revealed the presence of at least three well-differentiated phylogroups and a plausible specific boundary between peninsular and continental specimens (Torricelli et al 2010). Recently, Greenslade (2015) has synonymized the monospecific genus Gressittacantha with Cryptopygus, and changed the name of the species from terranova to terranovus. Therefore, in this study we have applied the new name for this isotomid species endemic to Victoria Land.…”

High levels of genetic structuring in the Antarctic springtailCryptopygus terranovus

Previous work focused on allozymes and mitochondrial haplotypes has detected high levels of genetic variability between Cryptopygus terranovus populations, a springtail species endemic to Antarctica, until recently named Gressittacantha terranova. This study expands these biogeographical surveys using additional analytical techniques, providing a denser haplotype dataset and a wider sampling of localities. Specimens were collected from 11 sites across Victoria Land and sequenced for the cytochrome c oxidase subunit I mitochondrial gene (cox1). Haplotypes were used for population genetics, demographic, molecular clock and Bayesian phylogenetic analyses. Landscape distribution and clustering of haplotypes were also examined for the first time in this species. Only three (out of 67) haplotypes are shared among populations, suggesting high genetic structure and limited gene flow between sites. As in previous studies, the population of Apostrophe Island has a closer genetic similarity with those of the central sites, rather than with its neighbours. Molecular clock estimates point to early differentiation of haplotypes in the late/mid-Miocene, also supporting the view that C. terranovus is a relict species that survived on the Antarctic continent during the Last Glacial Maximum. The present genetic composition of populations represents a mixture of ancient and more recent haplotypes, sometimes occurring in the same localities

“…The genus Cryptopygus Willem, 1902 sensu stricto has not received its modern generic diagnosis and most of its “austral” species need to be revised (Rusek 2002, Deharveng et al 2005, Jordana et al 2009, Potapov et al 2013, Greenslade 2015). Several species related to Cryptopygus antarcticus Willem, 1902 (the type species of Cryptopygus ) are common in the high latitudes of the Southern Hemisphere and form a clear taxonomic group.…”

Taxonomy of the Cryptopygus complex. II. Affinity of austral Cryptopygus s.s. and Folsomia, with the description of two new Folsomia species (Collembola, Isotomidae)

Folsomia minorae sp. n. and Folsomia australica sp. n. are described from New Zealand and Australia, respectively. Their possible affinity to two different groups of Cryptopygus sensu stricto is discussed. Attention is paid to the variability of sensillary patterns of the genital segment in Cryptopygus: mainly, all s-chaetae are subequal, but in more advanced forms the dorsal triplet, lateral duplet or either of them become macrochaeta-like in length. Cryptopygus ulrikeae (= Folsomia ulrikeae Najt & Thibaud, 1987), comb. n. is given a new generic position.
