Paranysson brevispinosus Arnold, 1929:391, ♀. Holotype: ♀, Zimbabwe: Sawmills (SAM), examined. – Arnold, 1930:7 (in checklist of Afrotropical Sphecidae); Leclercq, 1968:84 (in revision of African Paranysson; description of ♂; Democratic Republic of the Congo); R. Bohart and Menke, 1976:308 (in checklist of world Sphecidae).
RECOGNITION. The female of Paranysson brevispinosus is unique in having the hindcoxal spine that originates at the apical hindcoxal margin (Fig. 19). The clypeal teeth that protrude beyond the free margin between them constitute a subsidiary recognition feature (Fig. 17). The male is characterized by its tergum II impunctate basomedially or with a few, sparse punctures (Fig. 20), also a unique character; in large specimens, the hindcoxal venter is extended as an apical tooth on the inner side.
SEX ASSOCIATION. I agree with the sex association made by Leclercq (1968) because both sexes were collected together at several localities, where no other Paranysson were present.
DESCRIPTION. Clypeal lamella with two teeth at each side. Propodeal dorsum reticulate, basomedian cells elongate. Longitudinal carina between propodeal side and posterior surface either forming tooth at about two thirds of length or only broadened there. Both males from Gashaka Gumti National Park, Nigeria, have the legs entirely black.
♀ – Ocellocular distance equal to 0.9-1.2 × distance between hindocelli. Lateral clypeal teeth protruding beyond free clypeal margin between them (Fig. 17). Dorsal length of flagellomere I 1.6-1.7 × apical width, of apical flagellomere 1.6-1.7 × its basal width. Hindcoxal venter with spine that originates at apical hindcoxal margin; spine markedly shorter than hindcoxal venter (Fig. 19). Pygidial plate with punctures fine, sparse, to conspicuous, dense, in most specimens with fine, longitudinal ridges next to apex. Length 12.2-13.4 mm.
♂ – Ocellocular distance equal to 0.7-0.9 × distance between hindocelli; dorsal length of flagellomere I 1.1-1.4 × apical width, of apical flagellomere 1.5-1.7 × its basal width. In large specimens, hindcoxal venter extended as apical tooth on inner side. Tergum II impunctate basomedially or with a few, sparse punctures (Fig. 20). Tergum V sparsely punctate mesally, terga VI and VII closely so. Length 8.8-11.7 mm.
GEOGRAPHIC DISTRIBUTION (Fig. 21). Burkina Faso to South Africa.
