Abstract
Two new species of mites of the genus Zygoseius Berlese, Zygoseius papaver sp. n. and Zygoseius lindquisti sp. n., collected from moss and flood debris, respectively, in a creek in Chiapas State, Mexico, are described herein.
Highlights
The genus Zygoseius Berlese, 1916 is a moderately small genus of mesostigmatic mites, with 13 described species currently
The dorsal seta of trochanter I in Z. papaver and Z. lindquisti is inserted in a posterior position. We call this seta d (Figs 10, 23), in the chaetotactic formula, we indicated it as posterodorsal, given its clear posterior position, as in Halliday (1997)
We have examined adult specimens of other Zygoseius spp., as well as of Pachylaelaps (Pachylaelapidae), Gaeolaelaps (Laelapidae), Asca (Ascidae), Proctolaelaps (Melicharidae), Parasitus and Pergamasus (Parasitidae), and the dorsal seta of trochanter I was usually inserted in a slightly to moderately posterior position, and rarely on the mediodorsal line or in a anterior position
Summary
The genus Zygoseius Berlese, 1916 is a moderately small genus of mesostigmatic mites, with 13 described species currently. It was first defined by Berlese (1916) as a subgenus of Lasioseius Berlese, 1916, with description of the species Z. furciger, collected from ants’ nests in Argentina. Zygoseius species are found in soil, leaf litter, moss, compost, cow and chicken dung, and ants’ nests (Halliday 1997, Karg 1998, Karg and Schorlemmer 2009).
