 Diagnosis. The forewing length is 13–14 mm in males and 14–16 mm in females. Miltochrista auritiformis (Figs 7–11) is externally reminiscent of M. cornutia sp. n. (Figs 1–4) but distinguished by the broader and less elongate forewing, the antemedial fascia interrupted into four more or less rectangular spots (it is interrupted into two circular spots anteriorly and posteriorly in the congener), the rectangular discal spot (it is semicircular in M. cornutia sp. n.), and narrower and more longitudinally elongate spots of the postmedial fascia. The male genital capsule of M. auritiformis (Fig. 26) is most similar to M. modesta (Fig. 25) but differs clearly in the markedly broader valva with a large subbasal ventral costal lobe with a densely setose ventral margin and a medial ventral crest with a weakly setose ventral margin. The sacculus of M. auritiformis is narrower than in M. modesta, having a weakly setose dorsal margin (it is densely setose in the congener), and a somewhat shorter but markedly more robust distal process. Additionally, compared to M. modesta, the vesica of M. auritiformis has a longer distal diverticulum, and bears a thin and short cornutus laterally. In the female genitalia, M. auritiformis (Fig. 35) differs from M. modesta (Fig. 34) in the shorter, narrower and setose antrum (it is smooth in the congener), the anteriorly narrower ductus bursae, the posterior section of the corpus bursae having an oblique band-like sclerotised plate anteriorly edged with a broad and dense band-like cluster of small spines whereas in M. modesta, it has a sclerotised pocket edged with a narrower and shorter cluster of markedly more robust spines.   
 Distribution. The species is known from Northern Thailand (Chiang Mai Province) (Černý & Pinratana 2009), Northern Vietnam (Lào Cai and Hòa Bình Provinces), and Southwest China (Yunnan Province) (new country records).
