Dorsal idiosoma with 92 (90–92) weakly barbed setae. One pair of eyes, cornea 23 x 21 ( Fig. 1 ). Dorsal scutum punctate, a little wider than long (in two paratypes distinctly wider than long, in one paratype longer than wide), anterior border concave, posterior border slightly concave. Three pairs of scutalae (AL>ML>PL), all slightly barbed. Two pairs of sensillae with fine setules in distal half only ( Fig 3 ). FIGURES 1–2 . Charletonia cameroonensis Haitlinger & Kekeunou sp. nov.

Venter of idiosoma bears a pair of setae between coxae I, a pair of setae between coxae II, four setae between coxae II and III and 34 (30–32) setae behind coxae III; all setae setulose. Coxalae setulose, coxalae 1b longer than other coxalae ( Fig. 2 ). Gnathosoma. Galeala ( cs ) spiniform, nude, anterior hypostomala (as ) nude, over twice shorter than posterior hypostomala ( bs ), bs with relatively long setules.

Remarks . Charletonia cameroonensis Haitlinger & Kekeunou sp. nov . belongs to the species group with four setae between coxae II and III, Ti III> 320 Μm and Ta I> 190 Μm. This group includes C. dorotae Haitlinger, 1987 , C. taiwanensis Tsai & Chow, 1988 , C. ishii Southcott, 1991 , C. domawiti Haitlinger, 2004 , C. ramoni Haitlinger, 2007 , C. rajmundi Haitlinger, 2007 and C. mehranensis Haitlinger & Saboori, 2007 ( Haitlinger 1987 , 2004, 2007a, c; Tsai & Chow 1988 ; Southcott 1991 ; Haitlinger & Saboori 2007 ). Moreover, to this group C . brunni ( Oudemans, 1910 ) and C. volzi ( Oudemans, 1910 ) can be included—length of tarsus I and tibia III partly lies in the settled limit for this group.
