Female genitalia (Fig. 5): Length of apophyses posteriores 0.9, anteriores 0.4 mm. Length of ductus bursae 0.8, width 0.3 mm, strongly chitinised; angle between ductus bursae and upper margin of corpus bursae is about 90°. Projection of corpus bursae towards the ductus seminalis strongly chitinised. Corpus bursae with about 60 stout spines. Diagnosis — Habitus easily distinguishable from the other Idaea species except for I. textaria Lederer, 1861. Wing pattern very similar. Wing colour of /. textaria snow-white, slightly lustrous, termen of forewing slightly angled at CuAj. Differences in genitalia of male and female (see also Figs 4 and 6) are as follows: tip of valva in /. textaria much longer, aedeagus shorter (1.3-1.4 mm), length of cornutus corresponding to that of the new species but twice as thick: 0.22-0.27 mm, basal cornuti lacking. Ductus bursae more slender (about 0.2 mm), projection of corpus bursae towards ductus seminalis only poorly chitinised, corpus bursae with a comparatively small number (about 30-40) of small and weak spines.
