Cryptic Diversity in the Ubiquist Species Parisotoma notabilis (Collembola, Isotomidae): A Long-Used Chimeric Species?

Parisotoma notabilis is the most common species of Collembola in Europe and is currently designated as ubiquist. This species has been extensively used in numerous studies and is considered as well characterized on a morphological ground. Despite the homogeneity of its morphology, the sequencing of the barcoding fragment (5′ end of COI) for several populations throughout Europe and North America revealed four distinct genetic lineages. The divergence found between these lineages was similar to the genetic distance among other species of the genus Parisotoma included in the analysis. All four lineages have been confirmed by the nuclear gene 28S. This congruence between mitochondrial and nuclear signals, as well as the geographical distribution pattern of lineages observed in Europe, supports the potential specific status of these lineages. Based on specimens from the type locality (Hamburg), the species name was successfully assigned to one of these lineages. This finding raises several problems as Parisotoma notabilis has been widely used in many ecological studies. Accumulation of new data for the different lineages detected, especially ecological information and life history traits, is needed to help resolve this situation.

Species of the genus Friesea (Collembola, Neanuridae) from New Caledonia and Vanuatu

Weiner W. M., Bedos A. & Deharveng L. 2009. — Species of the genus Friesea (Collembola, Neanuridae) from New Caledonia and Vanuatu. Zoosystema 31 (3): 507-518. ABSTRACT Four species of the genus Friesea Dalla Torre, 1895 (Collembola, Neanuridae) are described from New Caledonia (Grande-Terre and Loyalty Islands) and Vanuatu (Santo Island). Friesea hnaeu n. sp. from Lifou Island in the Loyalties is characterized by two anal spines and the absence of eyes. Friesea wabao n. sp. from two islands of the Loyalties and Grande-Terre has a unique combination of characters: 1+1 or less eyes, a reduced furca, 3 anal spines and 7 s-chaetae on the fourth antennal segment. Friesea santo n. sp. from Santo Island in Vanuatu has 3 anal spines, no eyes and 6 s-chaetae on the fourth antennal segment. Friesea septem n. sp. from Santo Island is characterized by a reduced number of eyes (5–7+5–7 eyes), well-developed muero, and 7 s-chaetae on the fourth antennal segment. The genus Friesea has the same number of species (3) on Grande-Terre, New Caledonia and on Loyalty Islands, with only one species shared. Two species of the mirabilis group, one in Vanuatu and one in New Caledonia, have 7 s-chaetae on the fourth antennal segment, a character unique in this group, suggesting biogeographical affinities between these two regions.

Revision of Palearctic species of the genus Dimorphaphorura (Collembola: Onychiuridae: Onychiurinae: Oligaphorurini) with description of new species.

Abstract In this paper, the Palearctic genus DimorphaphoruraBagnall, 1949 (Collembola: Onychiuridae), is revised. The diagnosis of the genus is defined within the tribe Oligaphorurini based on the development of the furcal area, shape of furcal rudiment, and furcal chaetotaxy. Six new species are described: D. olenaesp. n. from Ukraine, D. inyasp. n . , D. pseudoinyasp. n., D. sibiricasp. n., D. caucasicasp. n. , and D. sophyaesp. n. from Russia. The type species of the genus, D. differensBagnall, 1949 is redescribed, and the lectotype and paralectotypes are designated. All previously known species are redescribed or with additional characters complemented: D. alnus ( Fjellberg, 1987 ) comb. n. , D. chatyrdagi ( Kaprus’, Weiner & Pomorski, 2002 ) comb. n. , D. daii ( Pomorski, Skarżyński & Kaprus’, 1998 ) comb. n. , Dimorphaphorura eremia ( Kaprus’,Weiner & Pomorski, 2002 ) comb. n. , D. hackeri ( Christian, 1986 ) comb. n. , D. irinae ( Thibaud & Taraschuk, 1997 ) comb. n. , D. melittae ( Christian, 1993 ) comb. n. , D. pseudoraxensis ( Nosek & Christian, 1983 ) comb. n. , D. raxensis ( Gisin, 1961 ) comb. n. , D. steposa ( Kaprus’, Weiner & Pomorski, 2002 ). An identification key to all Dimorphaphorura species is provided.

Phylogeny of the Brachystomellidae (Collembola) — were the mandibles ancestrally absent and did they re‐appear in this family?

A phylogenetic study was carried out on the family Brachystomellidae, which was found to be monophyletic. The genera Brachystomella and Folsomiella were polyphyletic. Folsomiella nothofagutalis was removed from Folsomiella and placed in Neorganella. The analysis showed that mandibles were ancestrally absent in this group and then re‐appeared later in Probrachystomellides nicolaii.

COLLEMBOLA FROM THE MOLDAVIAN BANKS OF DNIESTER RIVER. NEW RECORDS

Abstract. The study of Collembola communities of banks of the Dniester River revealed 54 species of Collembola belonging to 35 genera and 13 families. Five species were common for all studied sites: Mesaphorura critica, Metaphorura affinis, Hemisotoma thermophila, Isotomodes productus and Parisotoma notabilis. The whole list of Collembola is included, three species are new for Moldova. The study revealed three new species for the science of the genera Micraphorura, Agraphorura and Mesaphorura. Description of Micraphorura gamae sp. nov. the most similar to Micraphorura pieninesis Weiner, 1988 is provided.

Two new species of the genus Leenurina Najt & Weiner, 1992 (Collembola, Neanuridae, Caputanurininae) from Primorskij Kraj (Russia)

Abstract Leenurina khualaza sp. n. and Leenurina pomorskii sp. n., two new species from East Russia (Primorskij Kraj) are described. They are closely related to Leenurina jasii Najt & Weiner, 1992 from North Korea, from which they differ mainly in the number of tibiotarsal chaetae (19, 19, 18 in the new species versus 18, 18, 17 in Leenurina jasii), several chaetotaxic features and organization of dorsal granulation. The two new species may be separated by tertiary granulation (large areas fringed with large secondary granules in Leenurina pomorskii, small rounded or hexagonal areas with smaller secondary granules in Leenurina khualaza), coloration (light blue in Leenurina khualaza versus white in Leenurina pomorskii) and number of eyes (2+2 eyes in Leenurina khualaza versus 3+3 eyes in Leenurina pomorskii). An updated diagnosis of the genus Leenurina Najt & Weiner, 1992 and a key to species of Caputanurininae are given.

“Sexually Armed” Species of the Genus Protaphorura (Collembola: Onychiuridae)

Abstract Species possessing mvo: Protaphorura bakhchisaraica sp. nov. and P. salsa sp. nov. from two peculiar habitats: xerothermic bushes in Ukraine (Crimea) and a salt lake shore in Russia (South Siberia) are described. Two other species with this organ, Protaphorura ianstachia Yosii, 1972 and P. stiriaca (Stach, 1946), are redescribed, discussed and their lectotypes designed. An identification key to all known Protaphorura species having mvo is given. The structure and arrangement of the organ is applied as a sharp diagnostic character at the species level.

Collembola of the genus Protaphorura Absolon, 1901 (Onychiuridae) in the Eastern Palearctic: morphology, distribution, identification key

Abstract Seven new species, Protaphorura jernika sp. n., Protaphorura abscondita sp. n., Protaphorura tuvinica sp. n., Protaphorura vasilinae sp. n., Protaphorura sayanica sp. n., Protaphorura oligopseudocellata sp. n. and Protaphorura nikolai sp. n. from different habitats of the southern Siberia and Far East of Russia, are described. Protaphorura ombrophila (Stach, 1960) is redescribed based on the type specimens. These species differ one from other and from all known species by dorsal and ventral pseudocellar formulae, number of pseudocelli on subcoxae 1 of legs I–III, parapseudocellar formula, chaetotaxy of body, structure of claw, size of postantennal organ and body length. Geographical distribution of all known Protaphorura species of Eastern Palearctic was analysed and an identification key to 50 species was provided.
