Note. In the check-list of the Palaearctic Heliocheilus, Fibiger et al. (2009) placed H. fervens to a distinct species-group (' fervens species-group'). By our opinion, H. fervens has no principal morphological differences from H. translucens and should be placed to translucens species-group.

Diagnosis. Wingspan 28–32 mm. The species externally differs from H. translucens in the brownish-orange head and thorax colouration, the brownish-orange ground colour of forewing, the well expressed pale triangular patches in the terminal area of hindwing of both sexes, and the more diffuse pattern in females; from H. tengri it differs in the brownish-orange head and thorax colouration, the brownish-orange ground colour of forewing, and the less expressed pale triangular patches in the terminal area of hindwing of both sexes. The male genitalia differ from H. translucens in the less apically pointed cucullus and the somewhat smaller subbasal diverticuli in the vesica; from H. tengri in the somewhat broader and the less apically pointed cucullus, the somewhat longer vesica and the larger subbasal diverticuli in the vesica. The female genitalia differ from those of H. translucens in the shorter sclerotised part of ductus bursae, the smaller sclerotised area in the basal part of the appendix bursae, and absence of second long ventral band-like signum; from H. tengri they differ in the longer apophyses posteriores, the less sclerotised basal part of appendix bursae, the more sclerotised anterior part of the ductus bursae and the posterior part of the corpus bursae, presence of the small dorsal signum.

Distribution. Transbaikalia, Russian Far East (S Amur, S Khabarovsk and Primorye territories), Japan, Korea, eastern and southeastern China. Records of H. fervens from Tibet ( Hreblay et al. 1998; Kononenko et al. 1998; Kononenko 2003) belong to H. translucens .
