New records of Namibian Bombyliidae (Diptera), with notes on some genera and descriptions of new species Author Greathead, David J. text Zootaxa 2006 2006-03-10 1149 1 1 88 https://biotaxa.org/Zootaxa/article/view/zootaxa.1149.1.1 journal article 10.11646/zootaxa.1149.1.1 1175­5334 5058081 015DD261-8C5F-496E-A005-169ECDE3D10A Systoechus robustus Bezzi Systoechus robustus Bezzi, 1912: 608 . Systoechus bechuanus Hesse, 1936: 163 . syn. nov. Distribution. Botswana , Malawi , Namibia *, Zambia , Zimbabwe *. Material examined. 7♂♂ , 2♀♀ , 15 km W of Karabib on road to Usakos , 21°56’S 25°42’E , 5.iv.1998 , 97/98/244B general, F.W. & S.K. Gess ( AMGS ) ; 13♂♂ , 1♀ , Solitaire , 23°52’S 16°00’E , 30.iv.2002 , F.W. & S.K. Gess , general, 01/02/161 ( AMGS ) . Notes. Genitalia of Solitaire males are identical with those of S. bechuanus Hesse (illustrated in Hesse, 1938). Thus, the only character separating these species is the colour of the legs—dark­reddish brown to black in S. bechuanus and reddish­yellow in S. robustus —therefore S. bechuanus Hesse is a synonym.
