Apertochrysa ariadne (Hölzel, 1978) Anisochrysa ariadne Hölzel, 1978: original description Mallada ariadne (Hölzel, 1978): Brooks & Barnard, 1990 Dichochrysa ariadne (Hölzel, 1978): Aspöck & Hölzel, 1996 Pseudomallada ariadne (Hölzel, 1978): Duelli & Henry, 2020 Apertochrysa ariadne (Hölzel, 1978): Breitkreuz et al., 2021 Diagnosis: Available material: 7♀, 6♂ (Hölzel collection NMW; Crete) A small species with a bluish-green body (Fig. 13). No interantennal spot and dark marks on scape or vertex. No dark marks on thorax, abdomen, or wing base. Palps very dark brown. Face (frons, clypeus, scape) whitish. Subantennal sutures intensely red. Vertex yellowish-green. Female forewings 12.5–13 mm, male forewings 10.5– 11.5 mm. Costal crossveins dark at both ends, but never entirely dark. Furwing males (double set of setae on wing veins). Veins of im cell less than 20% dark, dark portion mostly in one piece. Gradate crossveins in both sexes darker than longitudinal veins. Distribution: Apertochrysa ariadne is endemic to the Greek island of Crete. It was collected on deciduous trees such as Quercus sp., Acer campestre, and Crataegus sp. (Hölzel, 1978). It seems to be most closely related to Ap2, in spite of the lack of dark marks on head and body.
