Holotype or syntypes: ♀, South Africa: Cape Province: Willowmore ( TMSA).— Arnold, 1930:20 (in checklist of Afrotropical Sphecidae View in CoL ).— As Bembecinus hyperocrus (Arnold) View in CoL : R. Bohart and Menke, 1976:531 (new combination, in checklist of world Sphecidae View in CoL ); S. Gess and F. Gess, 2003:115–116 (floral records), 2006:14 (floral records); Pulawski, 2014:18 (in catalog of world Sphecidae View in CoL sensu lato).

RECOGNITION. — Bembecinus hyperocrus View in CoL , inexspectatus View in CoL , and omaruru View in CoL are the only species within the rhopalocerus View in CoL group having the erect setae on tergum II, although in the female these setae are short dorsally and distinct only laterally ( Fig. 10b View FIGURE ). In all three species, the gastral terga are mostly ferruginous with some parts black (golden tan in several omaruru View in CoL ), and in the males of hyperocrus View in CoL and omaruru View in CoL the clypeus (all or nearly so), the supraclypeal area, and the frons are all black. Unlike inexspectatus View in CoL and omaruru View in CoL , the gastral terga of hyperocrus View in CoL have no pale yellow apical fasciae (the yellow fasciae are ill defined in omaruru View in CoL with golden tan gaster). Subsidiary recognition features of hyperocrus View in CoL are: the female clypeus black basally and markedly roundly angulate in profile ( Fig. 10a View FIGURE ), the male clypeus and the frons ventrally of the antennal socket are covered with dense, appressed vestiture, partly covering integument (no such vestiture in omaruru View in CoL , the integument easily visible).

GEOGRAPHICAL DISTRIBUTION.— Known principally from the winter rainfall Succulent Karoo from southern Namibia southwards through Namaqualand in South Africa and from the southern Nama-Karoo in South Africa from the Moordenars Karoo in the west to Willowmore in the east ( Fig. 24e View FIGURE ).

FLORAL ASSOCIATIONS.— Visiting flowers of four families: Amaranthaceae ( Hermbstaedtia glauca (Wendl. Reichb. Ex Steud.) , Zygophyllaceae ( Zygophyllum prismatocarpum E. Mey. ex Sond. , Campanulaceae ( Wahlenbergia sp. (label data, see Material Examined; S. Gess and F. Gess 2003, 2006), and Fabaceae ( Lebeckia ) (label data, see Material Examined).

NESTING.— Nesting in level, compacted, friable soil in the Goegap Reserve, near Springbok. Two nests were investigated (S. Gess). Burrows sloping, nest 87/88/61 not yet with a cell, nest 87/88/60 with a single sub-horizontal cell containing a larva and prey. Shaft diameter 5 mm, cell diameter 6 mm, depth of cell 55 mm. (F. Gess and S. Gess, field notes 87/88/60 and 87/88/61, AMSG).

PREY.— Cicadellidae (Homoptera) , adults (5 specimens double mounted on pins labeled 87/88/60, AMSG).
