Warren (1914) states
R. renigera Hbn. (=
dumosa Donz.) (13 e). Forewing greyish ochreous, thickly dusted with fuscous or grey, especially the space between outer and submarginal lines; markings obscure; lines marked by dark spots on costa; stigmata faintly yellowish; hindwing greyish fuscous. A south European species, found in Spain, France, Italy, Switzerland, Carinthia, Bosnia, and Hungary; also in Armenia, Asia Minor, Syria, Persia, Turkestan, and Mongolia: the Asiatic forms differ in colouration from the European; they have been separated by Staudinger as ab.
turana Stgr.[syn
Dichagyris devota (Christoph, 1884), which is pale ochreous, with the grey tinge less conspicuous: ab.
intermedia Stgr. [syn
Dichagyris forficula (Eversmann, 1851)] (13 e), which is dark violaceous grey with markings obscure; ab.
erubescens Stgr., in which the ochreous deepens into fulvous or reddish, and the markings become distinct; and ab.
funebris Stgr (13 e), which is leaden grey; but
erubescens [species
Dichagyris erubescens (Staudinger, [1892] and
intermedia [syn
Dichagyris forficula (Eversmann, 1851)] may well form a species apart, as Staudinger himself suggested. ==Subspecies==
