Figs 13A, B ; 14A, B ; Map 1

Type. ♀ holotype from Parc National de Moukalaba-Doudou , Département de Ndougou, Province de Ogooué Maritime (02°35’S, 10°14’E), GABON, III–IV.2003, O.S.G. Olivier & M. Burger leg. (forêt marecaguese) ( MRAC 220.827 ) .

Etymology. The specific name is a noun in apposition referring to the Myene people, which settled fishing communities along the coast of Gabon.

Diagnosis. Females of Carteronius myene sp. nov. resemble those of C. gentilis comb. nov. by the slightly curved epigynal transversal ridge ( Figs 14A , 19C ), but can be recognized by the posterior sector relatively larger; spermathecae barely visible by transparency in anterior sector ( Fig. 14A ).

Coloration: Carapace and chelicerae dark reddish-brown. Endites, labium and sternum dark reddish-brown. Legs reddish-brown, with femora I and II darker. Abdomen dark gray, with several small white spots, two pairs of small white spots in middle dorsally, and three faint chevrons posteriorly. Venter gray, with irregular white spots forming two transversal lines ( Fig. 13A ). Epigynum: CDv long, gently arched, ST2 tapering, anteriorly located, gland ducts present, approximately same size as ST1; CDd folded ventrally ( Fig. 14B ).

Other material examined. None.

Distribution. Only known from Gabon ( Map 1 ).
