Abstract

An annotated checklist of oribatid mite taxa from dipterocarp and polydominant forests of the Dong Nai Culture and Nature Reserve (Southern Vietnam) is presented. It includes 59 species, 46 genera and 29 families. The species Cycloppia restata, Tegeozetes tunicatus and the genera Cycloppia, Tegeozetes are first records for Vietnam. Truncopes moderatus variabilis is recorded for the first time in the Oriental region. Lyroppia dongnaiensis n. sp. (Oppiidae) is described from soil of dipterocarp forests. The morphology of gnathosoma and legs are presented in detail for the first time for this genus. An identification key to all known species of Lyroppia is given.

Highlights

This work is a part of our continuing study on oribatid mites of Southern Vietnam, and includes the data about oribatid mites of dipterocarp and polydominant forests from Dong Nai Culture and Nature Reserve
The morphology of gnathosoma and legs are presented in detail for the first time for Lyroppia
The new species is the second member of Lyroppia recorded from Vietnam

Summary

INTRODUCTION

This work is a part of our continuing study on oribatid mites of Southern Vietnam (see Ermilov and Anichkin 2010, 2011, 2012; other author’s papers), and includes the data about oribatid mites of dipterocarp and polydominant forests from Dong Nai Culture and Nature Reserve. The goal of this paper is to present an annotated checklist of oribatid mites from these forests with additional taxa, which we recorded from Vietnam and the Oriental region for the first time. Lyroppia is a small oribatid mite genus proposed by Balogh (1961) with Lyroppia scutigera Balogh, 1961 as type species This genus comprises five species, which are distributed in pantropic areas: Lyroppia anareolata Balogh and Ermilov S.G. and Anichkin A.E. Mahunka, 1981 (see Balogh and Mahunka 1981) from Brazil and Paraguay; Lyroppia delicata Lu and Wu, 1995 (see Lu and Wu 1995) from China; Lyroppia neotropica Balogh and Mahunka, 1974 (see Balogh and Mahunka 1974) from the Neotropical region; Lyroppia scutigera Balogh, 1961 (see Balogh 1961) from the Ethiopian and Neotropical regions; Lyroppia similis Balogh and Mahunka, 1977 (see Balogh and Mahunka 1977) from Bolivia. We provide an identification key to all species of Lyroppia
