Tenupalpa biformis is diagnosed by the glossy white forewing with a broad dark grey area in distal half, an orange distal patch and a black apical spot. The male genitalia are characterized by the apically pointed, large thumb-like anellus lobes and the juxta with a short-forked projection. The female genitalia are similar to T. venustalis as seen in the short apophyses anteriores and the corpus bursae without signum, but T. biformis can be distinguished from the latter by the medially elongate anterior margin of tergum VIII. Distribution . China ( Zhejiang ), Japan , Russia . This species is newly recorded from China . Remarks. The type materials deposited in ZIRAS of Russia were not examined in this study. A detailed re-description of T. biformis was provided in Kyaw et al . (2019) .
