Genus Gymnolaelaps Berlese 

Hypoaspis (Gymnolaelaps) Berlese, 1916: 170  .

Type species Laelaps myrmecophilus Berlese, 1892  , by original designation.

Diagnosis. Laelapidae  usually with a three-tined palp tarsal claw, proximal tine occasionally reduced, rarely absent; genital shield large, abutting anal shield, with 1–3 pairs of setae in addition to the genital setae st 5, all located on the edges of the shield; pre-sternal shield well-developed and sclerotised; a large subtriangular podal shield usually present posterior to coxa IV; epistome with irregularly serrated anterior margin; genu IV with nine setae including one ventral seta. Dorsal shield often with paired Zx setae between J and Z setae, unpaired Jx setae also often present; dorsal shield setae distally pointed, smooth or slightly serrated, not long and whip-like.

Notes on the genus. The genus Gymnolaelaps  has been collected in many parts of the world, almost always from ants' nests. The genus includes approximately 35 described species ( Hunter, 1967; Gu & Guo, 1997; Afifi & Abdel-Halim, 1998). Gymnolaelaps  has often been considered as a subgenus of a very broad genus Hypoaspis  , but we consider it to be a separate genus, following Evans & Till (1979). Nemati et al. (2000) reported five species of Gymnolaelaps  from Iran— G. hospes ( Berlese, 1923)  , G. myrmophilus ( Michael, 1891)  , G. vitzthumi Womersley, 1956  , G. australicus Womersley, 1956  , and an unidentified species. We follow Hunter (1961) in placing G. vitzthumi  in the genus Laelaspis  . Hunter (1967) reported that the type species G. myrmecophilus  has three stronglydeveloped tines on the palp tarsal claw, as do most other species in the genus. Two species, G. canestrinii ( Berlese, 1892)  and G. myrmophilus  , have a weakly-developed proximal tine, and in G. krantzi ( Hunter, 1967)  , there are only two tines. Jalalizand et al. (2004) reported Pseudoparasitus  sp. near australicus Womersley  and P. myrmecophilus (Berlese)  from Iran. We place both of these species in the genus Gymnolaelaps  , but we did not find specimens of G. myrmecophilus  in the present study.
