The Hawaiian endemic Viola kauaensis A. Gray has a broad distribution in bogs of Kaua`i and a limited distribution on mesic ridges in the Ko`olau Mountains of O`ahu. Based on differences in scale, the O`ahu populations of Viola kauaensis had previously been described as a distinct taxon. The taxonomic status of the O`ahu populations was reevaluated through a morphometric analysis of all varieti...

—Foza raimundi, a new genus and species of freshwater crab from Antsiranana Province,northernMadagascar, isdescribedfromahigh-altitude locality in the isolated Marojejy mountain range. The unusual combination of characters of the new species warrants the establishment of a new genus to accommodate this taxon. The new taxon is compared to the other species of freshwater crabs occurring in Madaga...

The holotype of Malerisaurus langstoni from the Late Triassic (Otischalkian) Trilophosaurus quarry 2 of West Texas is a chimera. The holotype represents at least 6-7 individuals of four reptilian groups: Trilophosauridae, Rhynchosauridae, Parasuchidae and Aetosauria. The majority of the material, including all of the cranial fragments, are re-identified as Trilophosaurus buettneri. Based on the...

Thirty-one occurrences of Erigeron parishii, a narrowly endemic plant threatened by mining, were sampled for allozyme diversity. This taxon held considerable genetic variation at the 14 allozyme loci surveyed. Species (e.g., alleles per locus [A] = 4.3 and proportion of polymorphic loci [P] = 0.64) and population (e.g., A = 2.15 [SD = 0.3] and P = 0.53 [SD = 0.12]) genetic diversity measures we...

Sakesphorus luctuosus (Glossy Antshrike) is endemic to Brazil, harboring two subspecies. The nominal subspecies is widespread in the Amazon region, and S. l. araguayae is endemic to the Rio Araguaia valley. In this paper we investigated the hypothesis that S. l. araguayae represents the end of a cline. We examined 588 specimens housed in Brazilian, North American and European museums and based ...

The tropiduchid monotypic genus Laberia Stål, 1866, endemic to Madagascar, is placed in a new tribe of its own Laberiini trib. nov. the subfamily Elicinae, and can be distinguished from other representatives by unique combination morphological characters head, tegmina, legs genital structures. only species palliata 1866 are redescribed, chresonymy presented nomenclatorial questions clarified.
