Hobbs, Horton H., Jr. Synopsis of the Families and Genera of Crayfishes (Crustacea: Decapoda). Smithsonian Contributions to Zoology, number IG4, 32 pages, 27 figures, 1974.—The subdivisions of the infraorder Astacidea, comprising the lobsters (superfamily Nephropoidea) and crayfishes (superfamilies Astacoidea and Parastacoidea) are briefly discussed and their affinities indicated. This is followed by a key to the superfamilies and of the families and genera of the Astacoidea and Parastacoidea… 
An Illustrated Checklist of the American Crayfishes (Decapoda, Astacidae, Cambaridae, Parastacidae)
This alphabetical list consists of the names of all of the American crayfishes that were described prior to 1 January 1988, including two fossil species that have been neither validated nor synonymized with other crayfish taxa.
The phylogeny of freshwater crayfish is assessed using a morphological analysis of fossil and extant taxa to support a monophyletic group (Astacida), and the familial affinity of Cambaroides is questioned and this genus is tentatively reassigned from the Cambaridae to the Astacidae.
Reassessment of cambaroides dauricus and C. schrenckii (Crustacea: Decapoda: Cambaridae)
The taxonomy of crayfish sampled from Mongolia, Russia, China, and North Korea was reassessed and detailed observations of apical robe of the male first pleopod did not support the taxonomy on the genus Cambaroides proposed by Starovogatov in 1995, however, some local variations of morphology exist in rostrum, pleuron, and telson of Asian cray fish.
Collecting and processing freshwater crayfishes
The phylogenetic connection of the Southern Hemisphere crayfishes shows a distinct linkage of southern South America, Madagascar, New Zealand, and Australia to the exclusion of continental Africa, a biogeographic distribution of considerable historical debate.
A new crayfish Family (Deacapoda: Astacida) from the upper Jurassic of China, with an interpretation of other Chinese crayfish taxa
A solution is suggested to the problematic biogeographic issue of the presence of the genus Astacus in a region presently occupied only by cambarid crayfish, a generic assignment that was made tentatively in the first place.
A revision of the genus Parastacoides Clark (Crustacea : Decapoda : Parastacidae)
Since the last revision of the genus Parastacoides, greatly extended collections, many from previously inaccessible areas, have become available. Some of the new specimens exhibited characteristics
Re-examination of the type material of Cambaroides schrenckii (Kessler, 1874) (Decapoda: Cambaridae) with a lectotype designation, re-description, and discussion on its phylogenetic position
It is shown that C. sachalinensis is a junior synonym of C. schrenckii, and the phylogenetic position of this genus is evaluated based on these characteristics.
A new species of crayfish of the genus Cambarellus (Decapoda: Cambaridae) from central Mexico
Principal component analyses and multivariate analyses of covariance resulted in the identification of significant differences between the newly proposed species and the rest of the analyzed Cambarellus species.
On the sexuality of South American Parastacidae (Crustacea, Decapoda)
Summary Ten parastacid species inhabit South American continental waters, grouped in the genera Samastacus, Virilastacus and Parastacus. The sexuality of these species is one of the most unknown and
Systematic Revision and Palaeobiology of Emplastron edwardsi (Van Straelen, 1928) gen. et comb. nov. (Crustacea, Decapoda, Astacidae) Entombed within Travertine, from Sézanne, France
Abstract. Crayfish are rare in the fossil record and therefore it is important to investigate each occurrence in detail. The only known fossil crayfish from France, Astacus edwardsi Van Straelen,


The freshwater crayfishes of South America

  • 1971
Most of the crayfishes are apparently burrowing species in contrast to species living in permanent streams and lakes, and are influenced by that of the Aegleidae which are widely distributed and common in many streams.
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

Les derniers paragraphes discutent les relations phylogenetiques entre les formes et les centres de developpement des diverses especes entre theales formes and categories systematiques au dessous du niveau subspecifique.
Six New Crayfishes of the Genus Orconectes (Decapoda: Astacidae) from Arkansas, Missouri and Oklahoma
A study of the crayfishes of the Ozark Mountains region of Arkansas, Missouri and Oklahoma has brought six new species and subspecies of these animals to my attention. These crayfishes all belong to
The Crayfishes of Kentucky, with Notes on Variation, Distribution and Descriptions of New Species and Subspecies
This study was undertaken in order to close a gap which has long existed in our knowledge of the distribution of the crayfishes. The Crustacea of the majority of the surrounding states have been
