Diagnostic characters. A. jaschhofi  CAN bEST bE SEPARATED fROM THE OTHER SPECIES DESCRIbED HERE, bASED ON THE fOLLOWINg COMbINATION Of CHARACTERS: LENgTH Of RM EQUAL TO LENgTH STEM Of THE POSTERIOR fORK  ; THE DORSAL LObE Of gONOSTyLUS IS SIMILAR TO A. karkloofensis  , WHICH bOTH HAVE A LARgE MEMbRANOUS AREA ON THE INTERNAL APEX Of THE LObE ( FIg. 10View FIGURE10); THE MEDIAN LObE IS NOT DISTINCTLy SEPARAbLE fROM THE OTHER SPECIES; THE bASAL PART Of THE gONOSTyLUS IS SIMILAR TO THAT Of A. karkloofensis  , bUT WITH A SMALL POINTED STRUCTURE PRESENT, WHICH IS AbSENT IN A. karkloofensis  ( FIg. 9View FIGURE9). THE fEMALE ( FIg. 8View FIGURE8) CAN bE SEPARATED fROM A. nyeriensis  ON SHAPE Of HyPOgyNAL VALVES ( FIg. 2View FIGURE 2).
