Broad-Scale Climatic Gradients Drive Multiple Facets of Scorpion Beta Diversity in Northeastern Brazil

  Broad-Scale Climatic Gradients Drive Multiple Facets of Scorpion Beta Diversity in Northeastern Brazil ABSTRACT Aim Beta diversity analyses clarify mechanisms structuring ecological communities, but their multidimensional facets remain poorly explored in arthropods. Here, we quantified taxonomic, phylogenetic, and functional beta diversity in scorpions, partitioned these facets into species replacement and richness differences, and evaluated the relative importance of spatial structure and environmental conditions in driving community assembly. Location Northeastern Brazil, South America. Taxon Scorpions (Arachnida: Scorpiones). Methods Taxonomic beta diversity was estimated using species presence across 70 sites in northeastern Brazil. Phylogenetic turnover was calculated from a multi-locus molecular tree, and functional beta diversity was derived from morphometric and ecological traits. All beta diversity facets were decomposed into replacement and richness-difference component...

A new species of Phlogiellus Pocock, 1897 from China (Araneae: Theraphosidae)

Abstract

A new species of theraphosid spider, Phlogiellus hakka Yao, Gong, Yu & Liu, sp. nov., is described from Fujian Province, southern China, based on both male and female specimens. This represents the first record of the genus Phlogiellus Pocock, 1897 from Fujian Province. Detailed morphological descriptions, supported by digital images (including SEM), and information on its natural habitat are provided. The discovery of P. hakka sp. nov. fills a significant distributional gap along the southeastern coast of China and is discussed in relation to the known biogeography of the genus in the region.
