Diagnosis of the Merodon aureus lineage
Mid coxa with long pile posteriorly ( Fig. 2A View Fig ); anterior anepisternum below postpronotum with many long pile ( Fig. 2B View Fig ); species with stocky abdomen ( Fig. 2C View Fig ); lateral sclerites of the aedeagus very small or absent ( Fig. 3A View Fig : marked with arrow).
Diagnosis of the Merodon bombiformis group
Pedicel elongated, approximately as long as basoflagellomere ( Fig. 4 View Fig ); abdomen broad ( Fig. 5 View Fig ); metafemur with less serrated apicoventral triangular lamina, usually only the apical dens is distinct ( Fig. 6 View Fig ); metatrochanter of males smooth, without calcar ( Fig. 6 View Fig ); male genitalia with posterior surstyle lobe usually bent (as on Fig. 7A, D View Fig : pl), and hypandrium narrowed medially (as on Fig. 7C View Fig : marked with arrow); distribution: Afrotropical Region ( Fig. 1 View Fig ).
The Merodon bombiformis group and M. funestus (Fabricius, 1794) differ from other species and groups among the aureus lineage by an elongated pedicel, approximately as long or even longer than basoflagellomere ( Fig. 4 View Fig ) and small lateral sclerite of the aedeagus (as on Fig. 3B, D View Fig : s) (absent in other species and groups of the aureus lineage, on Fig. 3A View Fig : marked with arrow). Morphologically, the M. bombiformis group can be distinguished from M. funestus by the absence of a calcar on metatrochanter in males (present in M. funestus , on Fig. 8A View Fig ), less dentate apicoventral triangular lamina on the metafemur, but usually with a distinct apical dens ( Fig. 8B View Fig ) (clearly dentate in M. funestus , on Fig. 8A View Fig ) and by the shape of the posterior lobe of the surstylus: tip rounded in bombiformis group (as on Fig. 13A, D View Fig : pl), but tapering in M. funestus ( Fig. 19A View Fig : pl).
