Diagnosis. Forewing length 10–12 mm in males. Wingspan is 20–25 mm. The new species ( Figs 4 –9) has no external differences from L. longaria ( Figs 1–3 ) and can be distinguished by the genitalia structure only. Compared to those of L. longaria ( Figs 16, 17 ), the male genitalia of L. kareli ( Figs 18, 19 ) have the much narrower and less curved uncus, the slightly more elongated tegumen, the broader juxta with weaker dentation, the broader valva, and the broader aedeagus and vesica.

Female is unknown.

Distribution. The new species is found in northern Myanmar (Kachin State), northern Thailand (Chiang Rai Province), northern Laos (Vientiane Province) and northern Vietnam (Hoa Binh Province).

Etymology. The species name is dedicated to Dr. Karel Černý, an expert in Asian Arctiinae and my friend.
