Ants of genus Formica demonstrate variation in social organization and represent model species for ecological, behavioral, evolutionary studies and testing theoretical implications of the kin selection theory. Subgeneric division of the Formica ants based on morphology has been questioned and remained unclear after an allozyme study on genetic differentiation between 13 species representing all...

Sadonebria Ledoux & Roux, 2005 is one of the more diverse subgenera of the genus Nebria Latreille, 1802 in East Asia, and its taxonomy remains unrevised at the subgeneric and specific levels. In this paper, two new species of this subgenus are described from Japan. Nebria quinquelobata sp. n. is described from Mt. Myôkô and is externally similar to Nebria saeviens Bates, 1883, to which specimen...

This study is based on oribatid mite materials collected by swiping bushes in central Madagascar. Four species are identified; a new subgenus and two species, Afreremella (Arboreremella) n. subgen., with type madagascarensis sp. (Eremellidae), Lucoppia ankaratraensis (Oribatulidae) described. An identification key to known representatives of provided. The initial subgeneric status Eremella (Arc...

A new species of Scheloribates (Perscheloribates) (Oribatida, Scheloribatidae) – S. (P.) oromiaensis sp. n. is described from mosses on the swamp at top mountain in Arsi Mountains National Park, Ethiopia; differs related ethiopicus by larger body size, rounded rostrum and pedotectum II, absence prolamella, presence aggenital seta. The taxonomic status Perscheloribates discussed, resulting suppo...

The article deals with the problem of nomenclature and classification phytoliths. division “crenate” morphotype (ICPN 2.0) into two forms – polylobate wavy is substantiated using Pooideae grasses from south Western Siberia. An analysis literature data confirms heterogeneity this various interpretations its variations. group includes phytoliths high in lateral projection distinct lobes, flattene...

Phylogenetic reconstructions are still lacking for many molluscan groups, making evolutionary inferences much weaker. The genera Cotonopsis Olsson, 1942 and Cosmioconcha Dall, 1913 are part of the so called Strombina group, and as such have been used as models to study patterns of speciation and extinction brought about by the rise of the Central American gateway. Earlier work, based on a few s...

In this study, two mitochondrial genes, cyt b and ND5, and the D2 expansion segment of the 28S nuclear ribosomal gene were used to reconstruct a phylogeny of the mosquito subfamily Anophelinae. The ingroup consisted of all three genera of Anophelinae and five of six subgenera of Anopheles. Six genera of Culicinae were used as the outgroup. Extreme conservation at the protein level coupled with ...
