Locus typicus: Namibia , Okahandja, Otjiamongombe [Erichsfelde]. Holotype : ♀. Namibia , 43 km N Okahandja, Otjiamongombe (Erichsfelde), 21°37’S 016°56'E , 07. II.2004 , J. Deckert (NMNW). Ethiopian material. Nech Sar N. P. ( Fig. 6 A), 05°58’N 037°35’E , 1110 m , 19.IX.2012 , P3632 (1 ♀), leg. J.-L. Boevé & A. Pauly ( RBINS ). This is the first record of A. deckerti for Ethiopia . Distribution. Botswana , Ethiopia , Kenya , Namibia , South Africa , Tanzania , Zambia , Zimbabwe . Host plant. Unknown. In southern Africa adults were feeding on pollen of Nidorella resedifolia DC. and N. auriculata DC. ( Asteraceae ). Remarks. Arge deckerti is very similar to A. stuhlmanni ( Kohl, 1893 ) , both being widely distributed ( Koch 2005 ), but A. deckerti clearly differs by the entirely yellow costa of the fore wing. In A. stuhlmanni the colouration of the costa and subcosta varies from a black apical half to blackish at extreme apex adjacent to the stigma. The lancet of A. deckerti is uniformly covered with sensilla, which are absent in A. stuhlmanni , and the serrulae are flatter. In lateral view, the penis valve of A. stuhlmanni is distinctly broader than in A. deckerti ( Koch 2005 ) . Until now A. stuhlmanni is not reported for Ethiopia .
