  ECOLOGICAL NICHE MODELS BY TITYUS SERRULATUS LUTZ & MELLO, 1922 AND TITYUS STIGMURUS (THORELL, 1876) (ARACHNIDA: SCORPIONES) Summary Scorpions are venomous animals with high plasticity and can serve as models for biogeographical, natural history, and evolutionary studies. Ecological niche modeling can help in understanding essential characteristics of the geographic distribution of species, as well as allowing the prediction of future distribution patterns. Our objective was to model the ecological niche of the scorpion species *Tityus serrulatus * and *Tityus stigmurus* , as well as to identify the variables that influence their distribution in different biomes and their range limits in the Amazon, Caatinga, and Cerrado biomes. Data were obtained from 12 Brazilian arachnological collections. Bioclimatic variables were obtained from the WorldClim database, and niche modeling was implemented using the Maximum Entropy algorithm. The results showed that the Atlantic Forest bio...

South African National Survey of Arachnida Photo Identification Guide: The Corinnidae of South Africa. Version 1 (2023)1-72

The Corinnidae is a moderately large cosmopolitan family known from 76 genera and 848 species (World Spider Catalog, 2023). The number of genera and species known from South Africa has increased considerably during recent years. Presently, 15 genera represented by 44 species are known from the South Africa, of which 23 species (52%) are South African endemics Twenty-eight of the species (63%) have a wide range and are of Least Concern, whereas 11 species are Data Deficient. Only five species of the genus Hortipes has been identified as species of special concern due to their restricted distributions. A key to the South African genera of Corinnidae is provided.
