Charletonia cameroonensis Haitlinger & Kekeunou sp. nov. and the first record of C. justynae Haitlinger, 1987 (Acari: Erythraeidae) from Cameroon with redescription of the species.

Charletonia cameroonensis Haitlinger & Kekeunou sp. nov. is described and illustrated from larvae obtained from Zonocerus variegatus (Linnaeus, 1758) (Orthoptera: Pyrgomorphidae) in Cameroon. For the first time C. justynae Haitlinger, 1987 is reported from Cameroon and from Z. variegatus and Eupezus rufipes Quedenfeldt, 1885 (Coleoptera: Tenebrionidae). This paper also presents new morphological data and a range of metric and meristic data for C. justynae. Distribution and hosts of Charletonia found on Orthoptera are given.
