Diagnosis. The length of the forewing is 8–9 mm in both sexes. This species is morphologically similar to L. digitatus sp. nov., but it can be distinguished by the following characteristics: the median fascia of the forewing is zigzag, with a brown marginal shade except for a reddish-yellow oviform mark near the apex. In the male genitalia, the valva is narrower than that of L. digitatus sp. nov.; the sella is not bilobed, ovoid, setose (editum); the phallus has a spine-shaped cluster of cornuti at the apical part. In the female genitalia, the antrum is not sclerotized; the ductus bursae is narrower than that of L. digitatus sp. nov.; the corpus bursae is ovoid, lacking sclerites near the cervix of the bursae.
