Notes

This species is most reliably distinguished in Hong Kong by the punctation on the dorsomedian area of the propodeum which is notably faint and/or sparse when compared to other Scolia species. The uniform absence of red coloration on the mesosoma and metasoma may also distinguish it from Sc. binotata and Sc. clypeata . The female of Sc. superciliaris is also much larger than other Scolia females we have seen from the region. Subspecies of Sc. superciliaris have been distinguished on the basis of the amount of red vs black coloration on the male antennae (Chinese Sc. s. superciliaris is supposed to have the antennae almost entirely black), but Hong Kong specimens range from having the flagellum almost entirely black to almost entirely red. Recognition of separate subspecies is therefore probably not warranted.

Identification key

Their striking appearance has made scoliids a popular subject for photographers, both amateur and professional. With this in mind, we have attempted to arrange this key with a focus on features likely to be visible in photographs of live specimens. Unfortunately, this has not always been feasible; some species will simply not be readily distinguishable without close examination under a microscope. Groups of particular concern in this regard include the red-fronted Scolia species ( Sc. clypeata , Sc. superciliaris , Sc. pakshaoensis sp. nov. and some colour variants of Sc. binotata Fabricius, 1804 as well as Carinoscolia junnanensis ( Betrem, 1928)) and male Campsomerini .

Photographs taken in Hong Kong and uploaded to the iNaturalist website (www.inaturalist.org/observations/42073499; www.inaturalist.org/observations/42444275; and, www.inaturalist.org/observations/72987049) show an unidentified species of Scolia . It may be Sc. formosicola Betrem, 1928 but confirmation of identity would require examination of specimens. It should be distinguishable from other scoliids in the region by its coloration: T2 mostly yellow with the remainder of the body predominantly black. Another photograph uploaded on the same website (https://www.inaturalist.org/observations/73932862) shows a male Scolia that we have not examined, it comes closest to Sc. clypeata pseudovollenhoveni Betrem, 1933 but confirmation would also require examination of specimens.
