Nucleotide sequence data from the mitochondrial 16S rDNA region were utilised to investigate phylogenetic relationships and species boundaries among Australian freshwater crayfish belonging to the genera Engaeus Erichson, 1846, Geocharax Clark, 1936 and Gramastacus Riek, 1972. Geocharax and Gramastacus were found to be monophyletic genera but one species currently assigned to Engaeus may belong to another genus. Relationships between the three existing genera were not resolved. Analysis of species boundaries within Geocharax suggests that there are an additional two species in this genus, and our analysis of Gramastacus indicates that undescribed populations from central New South Wales may comprise a second species. The data provide at least one instance of a taxon crossing the Great Dividing Range and provide confirmation of previously proposed hypotheses seeking to explain trans-Bass Strait distributions of species.

A new genus and new species of terrestrial freshwater crab, Calcipotamon puglabrum gen. nov. et sp. nov., is described from the limestone forests of Changjiang, Hainan Island, China, based on morphology and mitochondrial 16S rDNA sequences. The new genus is closest to Neotiwaripotamon Dai & Naiyanetr, 1994, and Tiwaripotamon Bott, 1970, but differs in a combination of carapace, third maxilliped, ambulatory leg and male gonopod characters. Molecular analysis shows that the new genus is closely related with but not clustered within other Hainan potamid genera. Notes on the general biology of this new species are also provided.

Two new species of potamid crabs, Eosamon daiaesp. nov. and Indochinamon malipoensesp. nov. are described from the Sino-Burmese border, southwestern Yunnan and from the Sino-Vietnamese border, southeastern Yunnan, China. The two new species can be distinguished from their closest congeners by several characters, among which is the form of the first gonopod structures. Molecular analyses based on partial mitochondrial 16S rDNA sequences also support the systematic status of these new taxa.

Species Groups

Phylogenetic analyses using 28S rDNA, elongation factor (EF)-1α, and mt 16S rDNA sequences were performed to test the monophyly of Thereva Latreille. Two of the three Afrotropical Thereva species groups lack the genitalia characters that unambiguously diagnose Thereva in the Holarctic Region, but phylogenetic relationships among Thereva species groups and therevine genera are poorly understood. Using an extensive taxonomic sample (39 of the 62 therevine genera) and Thereva, sensu lato (15 spp.), simultaneous analyses of all three gene partitions recovered Nearctic and Palaearctic Thereva species in a well supported clade that includes the Afrotropical seminitida-group but excludes the Afrotropical analis- and turneri-groups. Stronger phylogenetic signal from the EF-1α partition, measured by the skewness statistic and proportion of total parsimony informative characters, dominated conflicting signal from the 16S partition and weaker, but more congruent, signal from 28S. Reducing the taxonomic sample in analyses of Therevinae reduced homoplasy, increased phylogenetic structure and partitioned Bremer support values and reduced incongruence with 28S for the 16S partition. Although molecular analyses yielded partial recovery of informal therevine genus-groups, morphological diagnoses of higher-level groups are poorly supported with the exception of Cyclotelini. The ‘Holarctic radiation’ refers to a diverse clade of genera closely related to Pandivirilia Irwin & Lyneborg and Acrosathe Irwin & Lyneborg widely distributed throughout the Holarctic Region that is the sister-group to Thereva, sensu stricto. Results from these analyses underscore the importance of male and female genitalia characters in recognising monophyletic groups and regional endemism in therevine diversification.
