Triregia
Triregia is a genus of harvestmen in the family Triaenonychidae. The genus is endemic to New Zealand.
Description
In the original description, Forster described the genus as below:
T. bilineata can be identified due to a pair of small spinous tubercles on Tergal Area 4 and the posterior margin of scute, which T. monstrosa does not have. T. fairburni has a single median pair of tubercles in Areas 1-4, and an antero-median surface of carapace with five spines. The subspecies T. fairburni grata has four spinous tubercles in each of the areas 1-4, and seven spines on its carapace antero-median surface.
Taxonomy
The genus was described by Ray Forster in 1948, who named T. monstrosa as the type species. In 2020, phylogenetic analysis indicated that the genus is paraphyletic, with two harvestmen genera from New Caledonia, Triconobunus and Diaenobunus showing a close relationship with different species within Triregia. The authors of the study suggested a more thorough analysis of Triregia and related genera would need to be undertaken to clarify the taxonomic relationships between the different species.
Distribution
The genus is endemic to New Zealand, found on the upper North Island, and on Manawatāwhi / Three Kings Islands.
Species within the genus Triregia include:Triregia bilineata Triregia fairburni
