Figs 9 – 12 ; Map 1

Types. ♂ holotype from Kakum National Park , Kakum Forest (05°20’N, 01°23’W), GHANA, 17.XI.2005, R. Jocqué, D. de Bakker & L. Baert leg. (secondary forest, fogging), ( MRAC 218261 ) . ♂ paratype, same data ( MRAC) .

Etymology. The specific name is a noun in apposition referring to the Ashanti people, a major ethnic group of modern Ghana.

Diagnosis. Males of Carteronius ashanti sp. nov. resemble those of C. arboreus sp. nov. by the presence of a sub-apical embolar process ( Figs 8A , 10A ), but can be recognized by the long, narrow, upwardly oriented dorsal lobe of the RTA, by the prominent retrolateral apical tegular process and by the long, pointed apical spur in relation to the dorsal lobe ( Figs 10A, B , 12A, B, D, F ).

Length of leg segments: I 3.39+1.51+3.47+2.89+1.18=12.37; II 3.57+1.54+3.41+2.96+1.30=12.78; III 2.34+1.04+1.88+1.96+0.83=8.05; IV 2.82+1.07+2.47+2.47+0.91=9.74. Chelicerae: promargin with three spaced teeth, median tooth largest; retromargin with two spaced teeth, subequal in size. Leg spination: femora: I do 0-1-0 pl 0-1-0, II do 0-1-0, III do 0-1-0, IV do 0-1-0; tibiae: I ve 2-2-2-2-2-2-2, II ve 2-2-2-2-2-2, III ve p 1- r 1-2, IV pl 1-0-1 rl 0-1-1; metatarsi: I ve 2-2, II ve 2-2, III pl 0-1-0 vl 1-0-0 ve 2-2, IV pl 0-1-0 rl 0-1-0 ve 2-2. Coloration: carapace and chelicerae dark reddish-brown. Endites, labium and sternum reddish-brown. Legs reddish-brown, with femora I and II darker. Abdomen gray, dorsum with scattered small white spots, denser in middle, forming large irregular white longitudinal bands. Venter gray, with irregular white spots ( Fig. 9A ). Palp: RTA with ventral lobe sub-rectangular, without excavations, medial lobe narrow, as long as dorsal lobe. Sperm duct with loop restricted to middle of tegulum. Embolus with small subapical embolar process ( Figs 10A, B , 12A–I ).

Female. unknown.

Other material examined. None.

Distribution. Only known from Ghana ( Map 1 ).
