Differential diagnosis

Females of this species are easy to recognize within the satanas group. In contrast to those of S. satanas s. lat. ( Figs 113–114 View Figs 113–118. 113–114, 116 ) and S. socotrensis sp. nov. ( Fig. 116 View Figs 113–118. 113–114, 116 ), they have both the scutellum and the metanotum uniformly ferruginous ( Figs 109 View Figs 106–112. 106–107 ), a character which they share with female S. rufoclypeatus sp. nov. ( Fig. 110 View Figs 106–112. 106–107 ). However, S. rufoclypeatus sp. nov. has the clypeus and the anterior half of the scutum ferruginous, whereas the upper half of the clypeus and the entire scutum are black in S. pseudosatanas sp. nov.

Identification of males is more difficult.While male S. socotrensis sp. nov. stand out due to their ferruginous legs ( Fig. 117 View Figs 113–118. 113–114, 116 ), S. satanas satanas ( Fig. 115 View Figs 113–118. 113–114, 116 ), S. pseudosatanas sp. nov. and S. rufoclypeatus sp. nov. ( Fig. 111 View Figs 106–112. 106–107 ) all have a black integument and silvery setae. The most reliable characters to distinguish them are a combination of wing infuscation and placoid pattern. The male of S. satanas satanas has uniformly fuscous forewings and largely fuscous hindwings, whereas in S. pseudosatanas sp. nov., only the apex of the forewing is fuscous. Sphex rufoclypeatus sp. nov. has slightly infuscate forewings and hyaline hindwings. Sphex satanas satanas and S. pseudosatanas sp. nov. share the pattern of narrow placoids on the proximal half or third of flagellomeres IV–VI, whereas S. rufoclypeatus sp. nov. has broad placoids covering the entire length of flagellomeres III–VI.

Etymology

‘Pseudo-’ is a prefix derived from the Greek adjective ‘pseudḗs’ meaning false; ‘ pseudosatanas ’ thus refers to the fact that this species can be confused with the similar S. satanas .
