ABSTRACT Here we report an early Pleistocene occurrence of the New Zealand freshwater crayfish (kōura) Paranephrops White 1842 in the marginal-marine sediments of the Hautotara Formation, southeastern Wairarapa. The disarticulated parts are tentatively assigned to P. ?planifrons. This, to our knowledge, is the first fossil occurrence attributable to an extant species of Paranephrops, and only the second fossil occurrence of Paranephrops reported in the literature. This find provides a maximum…

Gill morphology and formulae of crayfishes (Decapoda: Astacidea: Parastacidae) from New Guinea and New Zealand and a comparison with other selected species of crayfishes
TLDR
The gill morphology of four species of crayfishes belonging to Astacoidea and ParastacoideA, two coral reef species of Enoplometopoidea, and 2 deep-water species of Nephropoides are described and illustrated for comparisons and to determine characters characteristic to members of the family Parastacidae (Parastacoides) from New Guinea.

A new species of Paranephrops White, 1842: A fossil freshwater crayfish (Decapoda: Parastacidae) from the Manuherikia Group (Miocene), Central Otago, New Zealand
TLDR
The specimen, a nearly entire molted carapace and abdomen, represents the first occurrence of this genus, and the family Parastacidae, in the fossil record of Paranephrops fordycei.
Mitochondrial phylogeography of New Zealand freshwater crayfishes, Paranephrops spp.
TLDR
Estimates of node ages and the phylogenies are inconsistent with both ancient Oligocene and recent postglacial Pleistocene range expansion, but suggest central to north colonization of North Island and west to east movement in South Island during mid‐ to late Pliocene.
Historical biogeography of the New Zealand freshwater crayfishes (Parastacidae, Paranephrops spp.): Restoration of a refugial survivor?
TLDR
New Zealand's two species of freshwater parastacid crayfishes have allopatric distributions, which gives the appearance of a vicariance event driven by uplift of the Southern Alps beginning in the Pliocene, and of former land connections across both Cook Strait and Foveaux Strait.
Systematics of the New Zealand freshwater crayfish Paranephrops (Crustacea: Decapoda: Parastacidae)
Summary The systematics of the endemic New Zealand genus Paranephrops (Family Parastacidae) are re‐examined. Specific characters previously used to separate P. zealandicus and P. setosus are
Distribution of the New Zealand crayfish Paranephrops zealandicus in relation to stream physico‐chemistry, predatory fish, and invertebrate prey
TLDR
The positive relationship with Chironominae indicates that any pre‐dation/bioturbation effect may be outweighed by crayfish shredding leaves and enhancing food supply for these collector invertebrates, which may propagate into lower trophic levels both directly and indirectly.

TLDR
Work should now focus on establishing reasonable, dated trees that satisfy rigorous assessment of the available fossils and careful consideration of molecular tree methods, to explore wider questions in macroevolution.
A Simple Method for Bracketing Absolute Divergence Times on Molecular Phylogenies Using Multiple Fossil Calibration Points

TLDR
A central challenge facing the temporal calibration of molecular phylogenies is finding a quantitative method for estimating maximum age constraints on lineage divergence times and this method, exploiting the fact that the relative branch lengths on the ultrametric tree are proportional to time is provided.
