Sphex torridus F. Smith, 1873: 291 , ♀.

Differential diagnosis

Within the argentatus group, this species ( Fig. 58 View Figs 57–62. 57, 60–61 ) can be recognized through its ferruginous or yellowbrownish wings and the erect setae on the face and propodeum being uniformly black. Females of S. voeltzkowii also have black erect facial and propodeal setae, but their wings are hyaline with a yellow tinge, and the coloration of the wing apices is different as well: forewing and hindwing margins are completely infuscate in S. torridus , whereas S. voeltzkowii only has a fuscous spot on the anterior part of the forewing apex, with the apical hindwing margin being hyaline. Additionally, males of S. voeltzkowii ( Fig. 59 View Figs 57–62. 57, 60–61 ) have a significant portion of the erect setae on the clypeus and paraocular area silvery or silvery-golden, while these are uniformly black in males of S. torridus . Sphex taschenbergi also has erect clypeal and propodeal setae that are black ( Figs 52, 54 View Figs 49–56. 49 ), but its wings are basally infuscate and otherwise hyaline.
