Diagnosis. Male with head and mesosoma mostly brown, except testaceous areas; notauli incomplete; inner side of paramere without mosaic sculpture ( Fig. 5B View Fig ).

Description. Male. Fully winged; length 2.1–2.8 mm (holotype 2.1 mm). Head brown, except mandible, clypeus and anterior half of face testaceous; antenna testaceous-dark; mesosoma brown, except pronotum and a small area behind hind tegula testaceous (small area behind fore tegula and hind tegula testaceous in paratype); metasoma brown; legs testaceous.Antenna filiform; antennal segments in following proportions: 6: 6: 7: 9: 11: 11: 10: 9: 8: 10. Head shiny, convex, punctate and granulated; frontal line absent; occipital carina complete; POL = 5; OL = 2; OOL = 4.5; OPL = 0.5; TL = 2; greatest breadth of posterior ocellus as long as TL. Scutum dull, granulated. Notauli incomplete, reaching about 0.7–0.8 length of scutum (0.8 in holotype). Scutellum granulated and punctate. Metanotum shiny, unsculptured. Propodeum reticulate rugose, without strong transverse keel between dorsal and posterior surface; dorsal and posterior surface with tracks of two median longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein longer than proximal part (18: 13). Inner side of paramere without mosaic sculpture ( Fig. 5B View Fig ). Tibial spurs 1/1/2.

Female. Unknown.

Differential diagnosis. Based on the characters summarized in the above diagnosis, in the Afrotropical Region the new species can be easily recognized from the other males of Afrotropical Thaumatodryinus by the incomplete notauli. In all other species in fact the notauli are complete.

Hosts. Unknown.

Etymology. This species is named after my (RSC) friend, Dr. William A. Overholt, the internationally known expert in the use of wasp parasitoids for the biological control of insect pests.

Distribution. Only known from Coast Province ( Kenya).
