New taxonomic considerations in the spitting spider family Scytodidae (Arachnida: Araneae).

New taxonomic considerations in the spitting spider family Scytodidae Blackwall, 1864 are proposed. Here, the family is considered to include two subfamilies: Scytodinae Blackwall, 1864, comprising the genera Scytodes Latreille, 1804 and Dictis L. Koch, 1872, and Scyloxinae subfam.

Reevaluating scorpion ecomorphs using a naïve approach.

Background: Ecomorphs create the opportunity to investigate ecological adaptation because they encompass organisms that evolved characteristic morphologies under similar ecological demands. For over 50 years, scorpions have been empirically assigned to ecomorphs based on the characteristic morphologies that rock, sand, vegetation, underground, and surface dwellers assume. This study aims to independently test the existence of scorpion ecomorphs by quantifying the association between their morphology and ecology across 61 species, representing 14 families of the Scorpiones order.

On Sahastata (Araneae: Filistatidae): complementary description of the generotype and two new species from Oman and Morocco.

The Filistatinae genus Sahastata Benoit, 1968 is distributed in arid and semi-arid areas, from westernmost Sahara to India, and includes seven known species. Four of these are only known from one sex, including Sahastata nigra (Simon, 1897), the type species. Here we present the first description of a male of this species collected near the type locality in Muscat, Oman.

Karyotype evolution and preliminary molecular assessment of genera in the family Scorpiopidae (Arachnida: Scorpiones).

The scorpions represent an ancient and morphologically conserved order of arachnids. Despite that, their karyotypes may differ considerably even among closely related species. In this study, we identify the trends of the karyotype evolution in the family Scorpiopidae based on integrating cytogenetic data and multi-locus molecular phylogenetic approaches.
