Description of a new species of Stueningeria Lehmann, 2019 (Lepidoptera, Cossoidea, Metarbelidae) from Kinmen Island of Taiwan

During an investigation of the lepidopteran fauna of Kinmen island in 2022, a Stueningeria species that had never been reported by any of previous entomological studies on Kinmen was discovered.Based on the morphological characters distinct from other congeneric species, we determine the specimens from Kinmen as a species new to science.

In addition, “Arbela dea" was often regarded as a timber pest in China and Taiwan. This species, however, has already been transferred to Marcopoloia and restricted to Myanmar. Another pest species, which has been misidentified as “Arbela baibarana” (a junior synonym of Marcolopoia discipuncta) in Chinese literature for long, is actually belonging to Stueningeria.
