Doratura (Doratura) rikele Guglielmino & Bückle, 2021: 80 In addition to the characters provided in the original description, we give some information on the coloration and mention some further characters concerning the male genital apparatus.

Description. Coloration (Figs 27D, E). With the general characters described for the genus Doratura (see above). Vertex in dark specimens with indistinctly delimited spot in posterior half, dark markings in the middle of pronotum and scutellum forming sometimes ± continuous sagittal band from vertex tip to scutellum. Wings without metallic colour, with light veins and ± hyaline cells, in dark specimens cells somewhat fuscous with light veins. Abdomen light with eight longitudinal bands, central ones very close to each other, divided by noticeably light middle line, middle ones consisting in small transverse spots on each tergite, lateral ones irregular, often interrupted near hind border of tergites; in light specimens bands almost lacking, reduced to rows of isolated small spots.

Male genitalia. Connective (Fig. 2K) small with basal part shorter than branched part, distinctly narrowing at mid-length. Pygofer (Fig. 3D) with more than ten macrosetae along almost its complete caudal margin.

Fifth instar (Fig. 25D). The available nymphs (15) are almost completely light, straw coloured without distinct markings. Dark spots on vertex present, but indistinct. In some specimens abdomen with indistinct darker band on both sides, central and lateral area light.

Diagnosis. D. rikele shares with D. heterophyla and D. kusnezovi the stout styles (Figs 28L–N) with only slightly tapering apical portion, furthermore the median notch on the hind margin of the female pregenital segment (Fig. 20L) and the smooth aedeagus (Figs 28E, F) without spinules or teeth. From both taxa it is distinguished by evenly bent and comparatively short styli (in the two other taxa long, in the basal third distinctly curved, in the apical portion almost straight), by the equal width of the aedeagus over most part of its length (distinctly tapering in its apical half in the other two taxa), by the short genital plates (Fig. 29D) (distinctly longer in the other taxa), and by the widely rounded (not split-shaped or narrowly rounded) notch on the hind margin of the pregenital segment in females. Furthermore, it differs from D. heterophyla by lower size and shorter wings (Figs 27D, E), from D. kusnezovi by the hook-shaped apex of the styles.

Distribution (Figs 57, 60A). Until now, D. rikele was found only in a restricted area in South Italy (Calabria; hillsides between the Sila Mountains and the Ionian Sea).

Ecology. The species occurs on rather arid hillsides at 500– 600 m. It was collected along fields with mixed ruderal vegetation, on argillous Hyparrhenia biotopes and in a dry Pinus forest with undergrowth of Cistus and sparse Poaceae .

Phenology. The species was found between the end of May and the beginning of September; it has probably two generations.
