(sieving along trail in primary rainforest) ( MRAC 223.475 ) . ♀ paratype , same locality and collectors, 10.XI.2006 (Fog 3, primary rainforest) ( MRAC 220.925 ) . Etymology. The specific name is a Latin adjective meaning arboreal, in reference to the fact that most of the known specimens were collected by canopy fogging. Diagnosis. Males of Carteronius arboreus sp. nov. are similar to those of C. ashanti sp. nov. by the presence of a sub-apical embolar process ( Figs 8A , 10A ), but differ by the dorsal lobe of the RTA, which is broad and retrolaterally oriented, and the rounded medial lobe, which is small in relation to the dorsal lobe, and share the same base ( Fig. 8B ). In C. ashanti sp. nov. , the dorsal lobe is spoon-shaped and the medial lobe longer and fang-shaped, with its own base. Females resemble those of C. sudanus comb. nov. in the strongly recurved epigynal transversal ridge ( Figs 4C , 8C ), but differ by the lateral plates of the epigynal posterior sector being strongly sclerotized ( Fig. 8C ).
