I believe this statement complies with requirements for a properly constituted typespecies designation, and that this was probably known to Engel as he makes reference to Röder’s work.  Diagnosis: Stenopogonine asilids with the following combination of characters. Head: Antennal postpedicel elongate, slender; style composed of 3 elements (2 slender segments and terminal spine-like seta); head clearly wider than high in anterior view (not more-or-less circular); face slightly convex; mystax covering entire face; vertex distinctly excavated; angle of divergence of frons/vertex in anterior view>20°; palpi 2-segmented; proboscis straight. Thorax: Anatergites bare; metepisternal macrosetae present; postmetacoxal area membranous; pulvilli well developed; wing with cells r 1and m 3open at margin; costal vein extending around entire wing margin (although weakly around anal cell and alula); ‘stump-vein’ at base of R 4absent. Abdomen: Segments clearly wider than long (i.e. moderately dorsoventrally flattened); terga more densely setose laterally.  Natal Museum specimens of  Acnephalumstudied:   A. fasciculatus( Loew, 1847)–  1♀‘Graec.

This may be of significance when a revision of  Acnephalumis undertaken. [463,1138,991,1013] NMSA J.
