Introduction

The Phreatoicidea is a group of freshwater and subterranean isopods that occurs in India, South Africa and New Zealand, but is most diverse in Australia. The epigean (surface-living) species are best recognised by their amphipod-like appearance with a narrow body and well-developed pleonal epimera enclosing the pleopods. The fully hypogean (subterranean) species forms lack these features and appear worm-like. A single pair of styliform terminal uropods is characteristic of this isopod suborder.

The group is represented by Carboniferous to Permian marine fossils from the Northern Hemisphere and Triassic freshwater fossils in Australia (Nicholls 1944; Schram 1986). Nicholls (1943, 1944) recognised two families, Amphisopidae (=Amphisopodidae) and Phreatoicidae. Both families are quite heterogeneous, and have poorly defined subfamilies. In this work, Knott's (1975) recommendations for elevating Nicholls' subfamilies names to families are partially employed. Some genera, however, are shifted from their place in either Nicholls' or Knott's scheme. Recent phylogenetic estimates of many or most genera in the suborder (Wilson & Johnson 1999; Wilson & Keable 2001) suggest that some family-level taxa are sufficiently well supported to receive recognition, whereas others have uncertain relationships. As a result, some genera have not been placed in this classificatory scheme. The family Nichollsiidae Tiwari, 1951 is a junior synonym of the Hypsimetopodidae Nicholls, 1943 in the new scheme introduced here. The phreatoicid subfamily Phreatoicinae is restricted to New Zealand taxa, based on the recently revised Phreatoicus typicus Chilton (see Wilson & Fenwick 1999). Therefore, the subfamily for the south-eastern Australian Phreatoicidaeis (provisionally) Mesacanthotelsoninae Nicholls, 1944. This latter subfamily is not well defined, and may be paraphyletic with some of the other subfamilies, possibly the New Zealand Phreatoicinae.

We eliminated the subspecies category in phreatoicidean taxonomy because most subspecies in isopod taxonomy have been based on taxa with diagnosable differences, but with no evidence for introgression between the subspecies. This decision results in a increase in the described species in the suborder. In Australia, however, many species remain undescribed: estimates suggest that the total fauna may exceed 250 species (Wilson & Keable 2001).

Approximately a quarter of the 56 described species of phreatoicideans are subterranean or hypogean forms. Most of the species, except for the semiterrestrial Phreatoicopsis terricola are dependent on permanent ground water. Knott (1986) listed the distribution of many species and discussed their peculiar biology. Banarescu (1990) provided distributions of species in this suborder, but unfortunately uses nomina nuda from an unpublished thesis (Knott 1975).

Introduction

Amphisopodids are inhabitants of permanent freshwater lakes, streams, springs and seeps. One species, Phreatomerus latipes, lives along the margins of hot, saline springs in South Australia, a notable departure from the typical habits of most other species in the suborder.

The members of the family are found in southern Western Australia, South Australia and Victoria (Grampians). The three genera from Nicholls' Amphisopodinae and one genus from the Phreatomerinae are included in the redefined Amphisopodidae, based on a well-supported clade (Wilson & Keable 2001). This family is no longer based on the presence of the plesiomorphic right lacinia mobilis, which can be shown to be present in various forms in most phreatoicideans.

Diagnosis

Head short, slightly deeper than long, dorsally smooth; cervical groove absent; antennal notch absent. Eyes large, prominent, ocelli distinct as individual units. Coxae fused to body. Pleonites with large pleurae, much deeper than body in lateral view, bases of pleopods not visible. Pleotelson posterior margin reflexed dorsally, with distinct vertical lateral plates above insertion of uropods. Gut lacking typhlosole and hind gut caecae. Antennula terminal article either tubular or conical, penultimate article similar in length to more proximal articles. Both mandibles with lacinia mobilis. Pereopods with articular plate on distal posterior side of propodus. Pereopods 5-7 bases with prominent dorsal plate. Pleopodal endopods without plumose setae. Pleopod 2 appendix masculina acutely pointed and spine-like, with partially-enclosed ventral groove. Uropodal rami distally rounded with robust terminal seta.

Introduction

Members of this family are subterranean or at least surface burrowers. They occur in Western Australia, Victoria, Tasmania and notably India (Banarescu 1990). The Indian genus Nichollsia Chopra & Tiwari, 1950 is somewhat abberrant in the adult male form, but the juveniles and females are similar to Pilbarophreatoicus Knott & Halse 1999 (compare Gupta 1989 and Knott & Halse 1999), and indeed appear in cladograms near this new genus (Wilson & Johnson 1999; Wilson & Keable 2001). The diagnosis has been written for Australian taxa only.

Diagnosis

Generally elongate, colourless phreatoicideans. Head lacking eyes or mandibular (genal) groove. Pereon narrow, width close to head width. Typhlosole absent, gut round in cross section. Pleonites depth in lateral view equal to depth of pereonites, with at most small ventrolateral plates (pleurae), basal region of pleopods visible; pleonite 1 pleura subequal to depth of pleonites 2-5 pleurae. Pleotelson lateral length greater than depth; telsonic medial region broadly indented, not reflexed, lateral lobes absent. Pereopods 2-3 or 2-4 propodus articular plate either absent or tiny. Pereopods 5-7 propodus lacking articular plate; basis dorsal ridge present but only angular, never plate-like. Pleopod exopods 2-5 proximal article distolateral lobes subequal or longer than distal article, endopods 1-5 without marginal setae. Pleopodal protopods without lateral epipods. Male pleopod 2 endopod appendix masculina distal tip pointed and spine-like, or at least acutely rounded. Uropodal protopod ventral ridge lacking long simple setae projecting laterally; rami distal tips pointed, endopod usually lacking robust setaeor spurs on dorsal margin.

Introduction

Phreatoicids live in freshwater streams and lakes throughout the south-eastern Australian mainland, Tasmania and New Zealand. Nicholls (1944) divided the Phreatoicidae into three subfamilies, Phreatoicinae, Mesacanthotelsoninae and Paraphreatoicinae. The New Zealand Phreatoicinae are distinct from the Australian forms (Wilson & Fenwick 1999; Wilson & Johnson 1999; Wilson & Keable 2001), so this subfamily is herein excluded from Australian taxa. We assign all Phreatoicidae from Australia to the family-group name Mesacanthotelsoninae Nicholls, 1944 owing to its page priority over Paraphreatoicinae Nicholls, 1944. The subfamily category is retained in this instance owing to well established synapomorphies of the Australian and New Zealand phreatoicids and less support for non-phreatoicine clades (Wilson & Keable 2001; unpublished data). The type genera of the two subfamilies, Mesacanthotelson and Paraphreatoicus, might be closely related.

Diagnosis

Head with well-developed cervical groove. Pleonites much deeper than pereonites in lateral view, with large pleurae, basal region of pleopods not visible; pleonite 1 pleura distinctly shallower than pleurae of pleonites 2–5. Right mandible without distinct lacinia mobilis. Mandibular spine rows on linear pedunculate projection between incisor and molar. Pereopods with articular plate on posterior side of propodus. Pleopodal protopods III–V only with lateral epipods. Uropodal protopod with distoventral robust denticulate seta.

History of changes

Introduction

Crenoicus Nicholls, 1944 is transferred to this subfamily from the Phreatoicinae and Uramphisopus Nicholls, 1943 is removed from Phreatoicopsinae. In the following, we have elevated Nicholls' subspecies to species level, owing to a lack of information to support the subspecies category. Most of the features in the diagnosis for this subfamily are plesiomorphies at the level of the Phreatoicidae. Nicholls described numerous species and subspecies of phreatoicids, many from single specimens, which are now lost.

Diagnosis

Pleotelson with medial lobe reflexed dorsally; lateral lobes rounded (not as vertical plate) and distinctly separated from medial lobe. Mandible incisor process broad, wider than thick. Pleopodal protopods 2-5 with medial epipods. Uropodal rami distally spine-like and pointed, terminal robust seta not distinctly separated from ramus.
