Remarks. MEASUREMENTS WERE MADE ON SPECIMEN IN ETHANOL.

CO1 sequence data. FULL LENgTH, bIDIRECTIONAL SEQUENCES Of THE CO1 bARCODE REgION WERE SUCCESSfULLy ObTAINED fOR fOUR Of THE SIX NEW SPECIES, A. nyeriensis   , A. jaschhofi   , A. keurbosensis   AND A. drakensbergensis   . WE WERE UNAbLE TO ObTAIN CO1 SEQUENCES fROM THE TWO REMAININg NEW SPECIES; A. karkloofensis   AND A. mazumbaiensis   . INTERSPECIfIC P-DISTANCES AMONg THE AfROTROPICAL SPECIES RANgED bETWEEN 5.6% AND 11% ( TAbLE 2). THE gENETIC DISTANCE bETWEEN THE AfROTROPICAL SPECIES AND THE SIX OUTgROUP TAXA RANgED bETWEEN 10.2% AND 14.1%. ALL THE AfROTROPICAL SPECIES gROUPED TOgETHER WITH RESPECT TO THE OUTgROUP TAXA.
