Two new oribatid mite species of the genus Gittella from Ecuador (Acari, Oribatida, Oppiidae)

Two new oppiid mite species of the genus Gittella, G. variabilis spec. nov. and G. minor spec, nov., are described from Southern Ecuador. The first new species is morphologically similar to Gittella maxima (Balogh & Mahunka, 1981), however, it differs from the latter by the morphology of sensilli, notogastral setae and epimeral region. The second new species is morphologically similar to Gittella insularis Mahunka, 1998. However, it differs from the latter by the body size, number of inter-bothridial muscle sigilla and the morphology of rostral and interlamellar setae. The morphology of the gnathosoma is presented in detail for the first time for a species of this genus.
