(H.) cf. angustipennis(Klug, 1829), A. (H.) kneuckeri zabranskyi Bily, 1995, A. (H.) marginifera dhofarica Bily, 2003, A. (H.) wittmeri Bily, 1979;  Chalcogenia halperini arabica Bily, 2008 ( Buprestidae).  Distribution. Oman (Dhofar governorate); Saudi Arabia (Al-Baha and Asir regions).  Remarks. The new species closely resembles  O. formosa(Giraud), but differs from it in the following combination of characters: wing hyaline (partly infumate in  O. formosa); corona thick, 3.25−4.00 xas long as wide, with structure interrupted (thick to medium, 3.20−6.67, structure continuous in  O. formosa); metasomal length short to medium, 0.44−0.47 xas long as body (short to long, 0.43−0.55 in  O. formosa); ovipositor length rather long, 0.16−0.19 xas long as metasoma (usually short, 0.09−0.17 in  O. formosa); head and mesosoma with strong blue colour in some parts (never with blue evident in  O. formosa).  Etymology. This species is named in honour of Pierpaolo Rapuzzi, who participated in the breeding of this species from the dead wood of  Acaciasp.
