A new species of the genus Pacificabathynella Schminke and Noodt, 1988 is described from groundwaters Alaska (USA). This first record Bathynellacea Chappuis, 1915 far north America. has hitherto been known only states California (one species) Montana (three species). Paradoxibathynella Serban, 2000 are genera that show sexual dimorphism in thoracopod VI. yupik sp. nov. several unique features within genus: antenna eight-segmented; antennule slightly longer than antenna; setal formula maxilla...
Bathynella natans Vejdovsky, 1882, the first described Bathynellidae species, was found in a well Prague. Its original description short and incomplete, holotype already damaged 1899. The lack of type material resulted poor genus morphologically very homogeneous family. This troubled beginning is basis taxonomic problem that has led to assignment many species Europe other continents Bathynella. As currently understood, cosmopolitan, with more than 50 subspecies, most them insufficiently...
Abstract Bathynellidae is the neglected family of Bathynellacea, a groundwater group crustaceans with 33 genera and 107 species described almost half them included in ‘catch‐all’ genus Bathynella . Due to morphological homogeneity species, taxonomic uncertainties have accumulated over time. Therefore, explore phylogenetic relationships among taxa, combined approach using molecular data needed. In this paper, we performed analysis based on partial sequences COI 18S including 30 Bathynellidae....
A preliminary molecular phylogenetic framework for 12 genera (23 species) of the family Parabathynellidae from Europe, Australia, North Africa and India is presented based on mitochondrial nuclear markers (Cox1 18S). The generated hypothesis places Southeast Asia genus Paraeobathynella closer to European ( Iberobathynella , Paraiberobathynella Parabathynella ) than Australian Brevisomabathynella Atopobathynella Billibathynella Octobathynella Arkaroolabathynella Lockyerenella or Indian...
Abstract The systematic status of the controversial crustacean family Leptobathynellidae is investigated using molecular and morphological methods in this study. Partial sequences nuclear 18S gene are studied from 28 genera Bathynellacea several continents. analysis includes some most plesiomorphic Parabathynellidae, such as Billibathynella Brevisomabathynella Australia; Habrobathynella Parvulobathynella India; diverse Iberobathynella; cosmopolitan genus Hexabathynella; representative two...
A new genus and species of Bathynellidae is described from Texas (USA). Hobbsinella gen. nov. displays a unique combination morphological characters including seven-segmented antenna lacking medial seta on exopod, antennule much longer than antenna, three-segmented mandibular palp with sexual dimorphism, four segments endopod thoracopods I–VII, five spines sympod uropod three lobes the penial region male thoracopod VIII.Partial sequences cytochrome oxidase I (Cox1) 18S have been obtained...
Two new species of the genera Haplophallonella Serban and Coineau, 1975a Racovitzaibathynella 1994 are described from Africa. This is first record members order Bathynellacea Chappuis, 1915 Chad. Representatives genus have hitherto been known only Ivory Coast type locality, South irenae sp. nov. dumonti a unique combination morphological characters. includes: seven-segmented antennule; five-segmented antenna; labrum with special morphology, clefted; mandible without proximal tooth; no...
Three new species of Parabathynellidae (Crustacea: Bathynellacea) are described using morphological and molecular data, additional populations identified as Texanobathynella cf. bowmani placed within a phylogeny for the group. The finding Montanabathynella pecosensis sp. nov. entails southern range expansion over 1500 km genus, previously thought to be restricted Montana, USA. displays unique combination features, including eight main teeth on labrum; four six pars incisiva molaris mandible,...
