diagnosis
Diagnosis (Figs 6, 11, 16, 21). Upperside more or less scattered with groups of dark scales (or dark lines short or longer), scattered or more dense; in some specimens (mainly in the westernmost part of the distribution area) there are only a few dark scales in the forewing (except on the costa and in the terminal fascia), a little more dense in the hindwing; in other specimens (also among the most western ones) both wings are scattered with dense groups of dark scales; dark terminal fascia generally narrow, wider in Bulgarian specimens, in the hindwing it can be present or absent. Underside with fore- and hindwings more or less different in pattern and colour (identical in roraria s. str.): both wings scattered with dark vertical lines, but colour generally more orange-yellow in the forewing, more whitish yellow in the hindwing, whitish radiating streak (s) of the hindwing present (sometimes barely perceptible). In the female genitalia signum large (1.1 mm, exceptionally 1.6 mm). Bullae tympani without roundish lobe.
