A new species of Mediolata Canestrini from Spain (Acari: Stigmaeidae), re­description of M. chanti and a key to the known species of Mediolata Author Faraji, Farid Author Ueckermann, Edward A. text Zootaxa 2006 1151 27 39 journal article 50629 10.5281/zenodo.172142 ff32d688-175b-4c13-af1a-57a06e358a9b 1175­5326 172142 Key to adult females of Mediolata The following artificial key is compiled mainly based on the leg and palp chaetotaxy. Such data were ignored in the description of M. aegyptiaca ( Zaher & Soliman) , 1966 , hence not presented in the key. Also, another species of Mediolata described from Egypt , M. pentascuta ( Zaher & Gomma) , 1978 , is suspected to be conspecific with M. aegyptiaca . The mentioned differences between these two species seem to be intraspecific variations. This synonymy was also confirmed by Dr. Z. R. Soliman (senior author pers. comm.). To reach a definite conclusion regarding the identity of these species, the type materials need to be re­examined. These were not available during this study. 1.
