Euodynerus (Euodynerus) semiaethiopicus ( Giordani Soika, 1943)

Figs. 5 , 7E

Odynerus semiaethiopicus Giordani Soika 1943: 9 , fig. 4 (1, 2), ♁ (in subgenus Rhynchium )—“ Isole del Capo Verde: S. Thiago, Orgaos Grandes” (lectotype MSNG).

Euodynerus albomaculatus Gusenleitner 2000: 67 , ♁ (in subgenus Euodynerus )—“Kap Verdischen Inseln … Santo Ant„o; Tarrafal ” (coll. La Roche). Syn. nov.

Diagnosis. Readily distinguished from other African Euodynerus by the following characters: mesosoma not depressed, T1 with sharply defined translucent margin, T1–2 sparsely punctate with interspaces as wide as several punctures, S2 strongly bulging with a basal vertical face, pattern black with few whitish markings, male F11 digitiform and weakly curved. Genitalia in Fig. 7E .

Material examined. CAPE VERDE: S. Thiago, Orgaos Grandes , V.1898, leg. L. Fea, 1♁ 1♀ ( MSNVE, paralectotypes of Odynerus semiaethiopicus ) .

Distribution. Cape Verde ( Giordani Soika 1943; Gusenleitner 2000) ( Fig. 8 ).

Notes. Gusenleitner (2000) described Euodynerus albomaculatus comparing it to the unrelated Nearctic species E. megaera (Lepeletier) and stating that the shape of S2 was not known in other Euodynerus species, overlooking the Cape Verde endemic E. semiaethiopicus . Photos of the holotype of E. albomaculatus were examined and compared with a pair of paralectotypes of E. semiaethiopicus , allowing the finding of subtle differences in the width of the apical margin of clypeus and density of punctures at apex of T2 only. These differences are here regarded as simple intraspecific variability, making E. albomaculatus a junior synonym.
