Diagnosis. Males of Anthobosca hallucigenia are so distinctive there is no possibility that they could be confused with any other species. The bright yellow markings, medially protruding and carinate interantennal area, dentate hindfemur and spoon-shaped projections on the metasomal sterna immediately distinguish this species from all other Anthobosca .

Male. Body length 10–11 mm. Head (Fig. 3): inner eye margin with upper third slightly emarginate; flagellomere I 0.8x as long as broad, flagellomere II 1.4x as long as broad, flagellomere XI 1.3x as long as broad; flagellomeres V–X each with one tyloid; clypeal apex broadly truncate; clypeus and interantennal sclerite strongly projecting, transected by medial longitudinal carina. Mesosoma: hindfemur with strong medial angle on ventral surface. Metasoma: segment 1 longer than broad; sternum II and III each with large, spoon-like medial projection (Fig. 4); sternum VIII thickened apex about twice as long as broad, without spinose apical margin ( Fig. 2 ). Genital capsule ( Figs. 7 , 17 , 27 ): paramere subtriangular in lateral view, broadly visible in ventral view, with base twice as broad as apex, dististyle apically broadened and ear-like; aedeagus length subequal to volsella, apical lobes short, narrowly separated; volsella vertically bilobate apically, largely obscured by aedeagus and paramere, wrapping around dististyle in lateral view. Punctation: head, mesosoma and metasoma covered with dense contiguous punctures, appearing granular. Vestiture: head and mesosoma with very short golden, erect setae; metasomal setae golden, shorter and appressed. Coloration: body black to darkish brown particularly on mesosoma, with yellow markings: yellow band extending from mid frons to clypeal apex, band along lower two-thirds of inner eye margin; prothoracic notum yellow with yellow lateral spot (lacking in some specimens); pro- and hindcoxae with anterior yellow spot; scutellum and metanotum with large yellow medial spot (small in some specimens); propodeum with small medial and lateral spots; metasomal tergum I with small lateral spot (sometimes absent); sternum I and II with broad transverse medial band, broken medially on sternum II; tergum VI and VII yellow; sternum I posterior declivity yellow; sternum VI with yellow lateral spot; parameres yellow; femora black; tibiae and tarsi dark reddish brown; antenna black to reddish brown; wing membrane brown-tinted, darkest near coastal margin.

Female. Unknown.

Distribution. Map 3.

Etymology. The species epithet, hallucigenia , refers to the bizarre abdominal and facial modifications of the males.
