Acknowledgments:

This paper is part of a Ph. D. dissertation by the senior author, which was financially supported by the Department of Entomology, Faculty of Agriculture, Shiraz Branch, Islamic Azad University, Shiraz, Iran. We cordially thank A. A. Khaustov (Tyumen State University, Tyumen, Russia) for making the materials from the Russian Far East available. The research of the corresponding author (Omid Joharchi) was supported by a project sponsored by the Russian Science Foundation (No. 20-64-47015). We are grateful to the anonymous reviewers for their valuable suggestions.

Annotation:

Ma (1996) described Gaeolaelaps debilis as a new species from China, being just one female collected from the nest of Daurian ground squirrel, Spermophilus dauricus Brandt (Rodentia: Sciuridae), in the Jilin Province. Then he presented a supplementary description of this species, based on female and deutonymph specimens collected from soil in same province from China (Ma 2004); but they both lack some of the most important details concerning leg chaetotaxy and do not provide enough information for accurate and consistent species identification. In this paper, we redescribe the adult female of G. debilis (Ma, 1996) based on the newly collected specimens from new localities in China, Iran and the Russian Far East. Our work includes the first description of the male of this species. Moreover, a key to the species of Gaeolaelaps with setae st1 off sternal shield is presented.
