Additions to the spider fauna (Araneae) of Algeria: first records of five species from thenorthern Sahara

ABSTRACT

The spider fauna of the Algerian Sahara remains poorly studied despite its vast aridlandscapes and  unique ecological  conditions. In  this study,  we  report  five  spider  species  newlyrecorded from Algeria, based on material collected in the region of El Meghaier, n orthern Sahara. These are Rhysodromus  lepidus  (Blackwall,  1870)  (Philodromidae),Pellenes  hedjazensis  Prószyński,1993 (Salticidae), Theridion  jordanenseLevy  & Amitai, 1982 (Theridiidae), Ozyptila furcula  (Koch,1882), andThomisus zyuzini Marusik & Logunov, 1990 (both Thomisidae). Additionally, O. furcula,P. hedjazensis andT. zyuzini are recorded from Africa for the first time, and the genusRhysodromusSchick,  1965, is newly  reported  from  Algeria.  Photographs  of  the  habitus and  copulatory  organsare provided, along  with  a distribution  map  illustrating  both  known and  newly  recordedoccurrences, and notes   on the ecological conditions of the collection sites.
