  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...

A revision of the genus Coryssiphus Simon, 1903, with its transfer to Systariinae (Araneae: Miturgidae)


Abstract

The genus Coryssiphus Simon, 1903 is redescribed and found to be composed of two species. Coryssiphus unicolor Simon, 1903 is synonymised with C. cinerascens Simon, 1903, being the female of that species. Coryssiphus praeustus Simon, 1903 and C. cinerascens are redescribed and the genus is transferred from Liocranidae to Miturgidae: Systariinae based on a number of somatic and genitalic characters. The peculiar presence of Coryssiphus in Africa is briefly discussed.
