Abstract
Homalernis fluctuosa Suzuki & Jinbo, sp. nov., is described and illustrated from Honshu, Shikoku, Kyushu, Tsushima Island, Amamiooshima Island, and Okinawajima Island, Japan. This is not only the first record of the genus Homalernis but also of the tribe Schoenotenini from warm temperate zones in the Palaearctic region. The association of males and females of the new species was confirmed based on the mitochondrial gene cytochrome oxidase submit 1 (COI). We discuss the taxonomic positions of two alleged Homalernis species from Malaysia and the taxonomic position of Homalernis within Schoenotenini.

Homalernis fluctuosa Suzuki & Jinbo, sp. nov.
Japanese name: Sazanami-tatege-hamaki
Diagnosis: Homalernis fluctuosa, sp. nov., is most similar to H. arystis in characteristics of the forewings and female genitalia. The two species can be distinguished based on the following: in H. fluctuosa, the apical third of the forewing has three distinct narrow fasciae, and the hindwing is approximately 3/4 the length of the forewing, whereas in H. arystis, the apical third of the forewings has scattered dark scales and the hindwing is approximately 2/3 the length of the forewing. In addition, the pair of signa of the female genitalia of H. fluctuosa is narrower and less sclerotised than those in H. arystis.
Etymology: The specific name fluctuosa refers to the three narrow fasciae in the apical third of the forewing that appear as ripples (Latin: flucticulus).
