Diagnosis

Body elongate, dorsoventrally somewhat flattened. Head with dark dorsal median longitudinal band on frontovertex around ocelli, narrower than the pair of lateral white bands. Mesosoma (thorax) dark metallic blue; pronotum with a pair of white bands interrupted in the middle; mesoscutum with a median, longitudinal, metallic greenish-blue band. Antenna (Fig. 1) short, compact, scape flattened and expanded beneath, more or less triangular with the anterolateral margin about 0.25x the rest of dorsal margin, and 0.5x of dorsal length of pedicel; flagellar segments strongly flattened and transverse. Fore wing (Fig. 2) infuscate, with a complete, longitudinal, median dark band reaching up to apex and a second, smaller, triangular patch placed below the median band. Ovipositor subequal in length to mid tibia, not exserted apically. Live specimens are characterised by the wing tips which are folded upwards as the insect moves around in search of its host as reported by Prinsloo (1984).
