Two new species of pterygosomatid mites parasitizing geckos of the families Gekkonidae and Caprodactylidae are describedGeckobia africana n sp from Cnemaspis africana (Werner) from Tanzania and Geckobia milii n sp from Underwoodisaurus milii(Bory De Saint-Vincent) from Australia The former species is the most similar to Geckobia loricata Berlese 1892 but differs bythe presence of the propodonotal shield reduced to small platelets slender and blunt-pointed setae in the posterolateral part of theidiosomal venter and the absence of thick serrate ventral setae in posterior part of the idiosoma For the latter species and Geckobiasimplex Hirst 1926 a new species group is established based on the analysis of chaetotaxy of legs IndashIV Mites of this new speciesgroup differ from the indica group by the presence of five setae on tibiae IndashIII and setae lrsquoGI lrdquoGIV dFI dFII and lFIII Species ofthe genus Geckobia are recorded from hosts of the genera Cnemaspis Strauch and UnderwoodisaurusWermuth for the first time

1 Introduction

Mites of the family Pterygosomatidae Oudemans 1910 (Acar-iformes Prostigmata) are one of the most diverse groupof permanent parasites of reptiles They are representedby highly specific (mono- or stenoxeous) ectoparasites oflizards (Squamata Sauria) with the exception of Geckobiaenigmatica Bertrand and Pedrono 2000 found on tortoises(Testudines Testudinidae) [1] and species of the genusPimeliaphilus Tragardh 1905 found on terrestrial arthropods[2] To date the family Pterygosomatidae includes 182 speciesgrouped into nine genera recorded from all zoogeographicalregions except for the Antarctica [3 4]

Within the Pterygosomatidae the genus GeckobiaMegnin 1878 is the most species-rich with 73 species andsubspecies About two-thirds of the species are arranged intofour species groups based on a trochanter-tibia chaetotaxyof legs IndashIV [4 5] ie latasti haplodactyli ovambica andindica and into groups 0 j based on differences in a tarsalchaetotaxy of legs I [4ndash6] However about one-third of thespecies of the genus Geckobia is not assigned to any of the

groups due to their unique morphological characters orvague descriptions

Currently the genus is known from lizards of the fami-lies Gekkonidae Phyllodactylidae Carphodactylidae Diplo-dactylidae Eublepharidae and Liolaemidae [3 4] Addition-ally one species G enigmatica have been found on thetortoise Astrochelys yniphora (Vaillant) [1] The distributionof the genus is very wide including six regions the PalearcticAfrotropic Neotropic Indomalayan and Australasian eco-zones [3 4]

Below I describe two new species of the genus Geckobiafrom the infraorder Gekkota Geckobia africana n sp foundonAfrican geckoCnemaspis africana (Werner) (Gekkonidae)from Tanzania and Geckobia milii n sp associated withthick-tailed gecko Underwoodisaurus milii (Bory De Saint-Vincent) (Carphodactylidae) from Australia According tothe leg chaetotaxy pattern the former species belongs toGeckobia group 1 established by Jack [5] (the latasti groupof Fajfer [4]) whereas for the latter species and Geckobiasimplex Hirst 1926 I propose a new species group basedon its unique morphology Species of the genus Geckobia

2 Materials and Methods

All mites were collected form geckos preserved in 70ethanol in the Zoological Museum University of Copen-hagen Denmark The mites before mounting in Hoyerrsquosmedium were cleared and softened in Nesbittrsquos solution at50∘C for 1ndash3 hours Then the mites were studied using thelight microscope Olympus BH-2 with differential interfer-ence contrast (DIC) illumination and drawings were madeusing a camera lucida drawing attachment Allmeasurementsare given inmicrometres as the data for the holotype followedby the ranges for the paratypes Nomenclature of the legand idiosomal setae follows Grandjean [7 8] and namesof the palpal setae follow Grandjean [9] as adapted to thefamily Pterygosomatidae by Bochkov amp OConnor [10] Thescientific names of the lizards follow Uetz and Hosek [11]

Type-Locality Australia Far North Queensland Cape YorkPeninsula 9VI1914 coll unknown
