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of the Australian and New Zealand phreatoicids and less support for non-phreatoicine clades (Wilson & Keable 2001; unpublished data).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.
