  Systematic revision of the Savignia genus group (Araneae: Linyphiidae: Erigoninae) with notes on their cephalic lobe evolution Abstract The Savignia genus group includes nine morphologically complex yet similar genera where species were assigned based mainly on the cephalic lobes. Among these genera, males of Diplocephalus Bertkau, 1883, Savignia Blackwall, 1833 and Araeoncus Simon, 1884 show some of the most extraordinary cephalic lobes among dwarf spiders (Linyphiidae, Erigoninae). In this study we undertake the first phylogenetic analysis of the Savignia genus group. We use 269 morphological characters (175 newly defined) and 70 taxa (59 ingroup taxa) to reconstruct the relationships and evolutionary trends of cephalic lobes in this lineage. Our findings show that cephalic lobes with varying shapes and sizes appear in several Savignia genus group lineages, highlighting that it is not a good diagnostic character. The high support in several clades allows the redefinition of t...

Scorpions of the State of Kuwait

Abstract

This is the first preliminary study on the scorpions of Kuwait. Three species of scorpions were identified, described and illustrated from the State of Kuwait. Identified species belong to family Buthidae: Apistobuthus susanae, Androctonus crassicauda and Compsobuthus pallidus. Measurements were given for Apistobuthus susanae.  Morphometric measurements were given for the three species, along with comparison of Apistobuthus susanae and Apistobuthus pterygocercus.
