Nineteen species of ptyctimous mites were found in 20 samples collected in Cameroon: 15 samples from the Southwest region, near the ocean, and 5 samples from the Northwest region, inland. Two new species: Euphthiracarus (Pocsia) inaequatus sp. n. and Steganacarus (Rhacaplacarus) alius sp. n. are described and figured. Six species are new to Cameroon. The so far unknown instars of Mesoplophora (Mesoplophora) invisitata Niedbala, 1983: larva, proto-, deuto-, and tritonymph are described. The deutonymph and tritonymph of M. (M.) invisitata are compared with the corresponding stages of the related species. The tritonymph of the species of both subgenera, Mesoplophora and Parplophora , differ in the number of setae on the anal and adanal plates, which is an additional morphological character differentiating these subgenera. Two previously known species, Phthiracarus parabaloghi Niedbala, 1983 and Protophthiracarus diatropos Niedbala and Stary, 2014, show some morphological differences compared to their holotypes.

Steganacarus (A.) plakatisi (Mahunka, 1979) Distribution in Georgia. E: Khashuri (Shtanchaeva & Subías 2010) Global distribution. Mediterranean Ecology. Forest soils Remark. Shtanchaeva & Subías (2012) described S. (T.) achmedovi from various locations in Caucasus including Georgia. Niedbała (2015) compared this description with description of S. (A.) plakatisi from Greece by Mahunka (1979). He indicated the similarities in body size, sculpture, length and shape of prodorsal and notogastral setae and sensilli; as the only difference the number of ng setae (17–18 pairs in A. achmedovae and 16 – in A. plakatisi) is regarded, but Niedbała regarded this character as variable. Hence, the Caucasian findings are considered as new locations of S. (A.) plakatisi., Published as part of Murvanidze, Maka & Mumladze, Levan, 2016, Annotated checklist of Georgian oribatid mites, pp. 1-81 in Zootaxa 4089 (1) on pages 18-19, DOI: 10.11646/zootaxa.4089.1.1, http://zenodo.org/record/257567
