Hesslerella shermani is described as the oldest representative of the crustacean superorder Peracarida, order Isopoda, suborder Phreatoicidea. This description is based on a single specimen of exceptional preservation from the Middle Pennsylvanian of Illinois. The existence of isopods in the Pennsylvanian raises some questions concerning peracarid and eumalocostracan evolution.

A new isopod species, Eonatatolana geisingensis gen. et sp. nov., is described from Middle Jurassic shallow‐water sediments of southern Germany. It shows not only the almost completely preserved

The Trace Fossil Diplopodichnus from the Lower Jurassic Lacustrine Sediments of Central China and the Isopod Armadillidium vulgare (Pillbug) Lebensspuren as its Recent Analogue

The trace fossil Diplopodichnus isp. was identified in lacustrine siliciclastics of the Lower Jurassic Anyao Formation in the Henan Province, central China. This is the youngest occurrence of this

A new genus of phreatoicidean isopod (Crustacea) from the north Kimberley region, Western Australia

TLDR
The cladogram provided evidence for the monophyly of the Phreatoicidae and its New Zealand clade and suggested that clades of modern phreatoicideans diverged from one another during the Mesozoic Era after they entered fresh water, but prior to the fragmentation of East Gondwana.

Ancient endemism among freshwater isopods (Crustacea, Phreatoicidea)

TLDR
A phylogenetic analysis of 21 exemplar species showed that major cladogenic events took place prior to the fragmentation of Gondwana, and Nichollsia, a genus restricted to India, was deeply nested within a Western Australian and Victorian clade.

Pilbarophreatoicus platyarthricus n.gen., n.sp. (Isopoda: Phreatoicidea: Amphisopidae) from the Pilbara region of Western Australia

Pilbarophreatoicus platyarthricus , a subterranean phreatoicidean isopod from an intermittent stream in the arid Pilbara region of northwestern Western Australia, is described. With subterranean

A new genus of terrestrial isopods (Crustacea: Oniscidea: Armadillidae) in Myanmar amber

ABSTRACT A female terrestrial isopod in amber from Myanmar is described as Palaeoarmadillo microsoma gen. et sp. n. (Isopoda: Oniscidea: armadillidae). Placement in the family Armadillidae is based

New Malacostracan Crustacea from the Carboniferous (Stephanian) Lagerstätte of Montceau-les-Mines, France

Abstract Investigations of recently cracked concretions from the Carboniferous Montceau-les-Mines, France, Lagerstätte led to the recognition of two new malacostracan Crustacea: a palaeophreatoicid

ISOPODA: PHREATOICIDEA

One would expect with such a name that some species at least of the sub-order Phreatoicidea Stebbing, 1893 would inhabit the Stygal, and indeed the first phreatoicid found was collected from a well

Triassic Isopoda - three new species from Central Europe shed light on the early diversity of the group

TLDR
Three new species of Isopoda are described from two field sites in Europe and support the assumption that the transition from a dominance of Phreatoicidea towards the dominance of the remaining lineages of isopoda happened quite early (likely prior to the Triassic).

The origin of terrestrial isopods (Crustacea: Isopoda: Oniscidea)

TLDR
A pre-Pangaean origin of the Oniscidea is discussed and supported, in the Late Paleozoic—most likely during the Carboniferous, to replace this group in a deep-time context.
