TLDR
The taxonomic structure of this group is completely revised above the species level, excluding 5 genera from the family and all remaining subgenera are elevated to generic level.
Abstract
The increasing number of world-wide discoveries of subterranean amphipods, especially during the last two decades, has led to additions of numerous new taxa in the stygobiont family Bogidiellidae s. lat. To date, the family is composed of 23 genera and 11 subgenera, and approximately 110 described species. However, given the uneven quality of generic and subgeneric diagnoses in the literature, there is considerable confusion regarding the status of some of the taxa at these levels. Even the family itself lacks a clear definition. In order to gain a better knowledge of the phylogeny of this group, a cladistic analysis, employing both PAUP 3.0s and MacClade, was performed on the genera and subgenera currently assigned to the Bogidiellidae s. lat. Supported by the results of this analysis, the taxonomic structure of this group is completely revised above the species level. The revision excludes 5 genera from the family, all remaining subgenera are elevated to generic level. Four taxa are split, resulting in 5 new genera. The family Bogidiellidae now consists of 33 genera. Die wachsende Zahl weltweiter Neuentdeckungen von Grundwasser-Amphipoden, insbesondere wahrend der letzten zwei Jahrzehnte, erweiterte die Stygobiontenfamilie Bogidiellidae s. lat., um zahlreiche neue Taxa. Bis heute sind in der Familie etwa 110 beschriebene Arten in 23 Gattungen und 11 Untergattungen zusammengefasst. Aufgrund der unterschiedlichen Qualitat diagnostischer Beschreibungen herrscht allerdings erhebliche Verwirrung hinsichtlich des taxonomischen Status einiger Gruppen. Sogar die Definition der Familie selbst ist relativ undeutlich. Um neue Einsichten in die Phylogenie der Bogidielliden s. lat., zu erhalten, fuhrten wir eine kladistische Analyse der Gattungen und Untergattungen unter Verwendung der Computerprogramme PAUP 3.0s und MacClade durch. Die Resultate dieser Analyse dienten als hilfreiche Erganzung bei der umfassenden taxonomischen Revision der Gattungen und Untergattungen. Funf Gattungen wurden aus der Familie entfernt und alle Untergattungen zu Gattungen erhoben. Das Aufspalten von vier Taxa resultierte in 5 neuen Gattungen. Die Familie Bogidiellidae besteht somit aus 33 Gattungen.

Global diversity of amphipods (Amphipoda; Crustacea) in freshwater

TL;DR: Freshwater amphipods are greatly polyphyletic, continental invasions have taken place repeatedly in different time frames and regions of the world, and have had great impacts on European fluvial ecosystems.

A Phylogeny and Classification of the Senticaudata subord. nov. Crustacea: Amphipoda)

TL;DR: The Amphipoda includes a large clade defined by the presence of a previously unrecognised synapomorphy, apical robust setae on the rami of uropods 1-2, which is introduced for the first time in am-phipod classification, the level parvorder between infraorder and superfamily.

The Corona lava tube, Lanzarote: geology, habitat diversity and biogeography

TL;DR: The results of a diving exploration of the Corona lava tube are presented, and the origin of the diverse hypogean fauna, including new species of remipede crustaceans and polychaete worms discovered during the expedition are discussed.

Preliminary phylogenetic analysis of selected subterranean amphipod crustaceans, using small subunit rDNA gene sequences

TL;DR: The molecular analyses do not support the recognition of what initially appeared to be a new species of Bactrurus from glaciated areas in Montgomery County, Illinois, and the three methods of phylogenetic inference produced identical basal branching patterns.

Subglacial Refugia in Iceland Enabled Groundwater Amphipods to Survive Glaciations

TL;DR: It is argued that there were subglacial refugia in Iceland during the Quaternary glacial period, and the presence of subterranean amphipods, belonging to an old group with its present distribution mainly in North America and the Eurasian continent, indicates past contact with subterranean fresh waters of Iceland and the North Atlantic continent.
