Figs 50, 55 (red)

? Sphex argentifer Walker, 1871: 19, ♂ (holotype or syntype: ♂, Sudan, Red Sea, Akeek Island, destroyed). Synonymized with Sphex umbrosus by Kohl, 1890: 407.

Sphex lanatus Mocsáry, 1883: 34, ♂ (holotype: ♂, South Africa, “Transvaal”, TMB, not examined).

Differential diagnosis

Within the argentatus group, S. lanatus is characterized through its entirely silvery vestiture. Females (Fig. 50) can be distinguished from those of S. feijeni nom. nov. (Fig. 43) through having the propodeal sculpture largely obscured by appressed setae, whereas the propodeal vestiture is more sparse in that species and leaves 7–10 distinct transversal ridges visible that are absent in S. lanatus. Females of S. erythrinus are distinguishable through their yellow-tinged wings (Fig. 41).

Males of S. lanatus are recognizable by their longer and more slender petiole, the length of which is greater than 2.7 times its medial width. This coefficient is notably smaller than 2.4 in males of S. erythrinus (Fig. 42) and S. feijeni nom. nov. (Fig. 44). Furthermore, S. erythrinus and S. feijeni nom. nov. have the placoids covering at least flagellomeres III–V, whereas S. lanatus has only a single placoid on flagellomere V. Finally, S. rufinervis is similar (Fig. 51), but its erect clypeal setae are partially or completely black in both sexes.
