Review of the genus Lasiochira Meyrick, 1931 (Lepidoptera: Oecophoridae)

Abstract

The genus Lasiochira Meyrick, 1931 is reviewed, based on the specimens collected from China, Korea, and Vietnam. Of the eight species involved in this study, six are described as new: L. flavaterminata sp. nov., L. jianfengensis sp. nov., L. jiulongshana sp. nov., L. pallidiptera sp. nov., L. rosataenia sp. nov. and L. taiwanensis sp. nov. Photographs of adults and genital structures as well as the wing venation are provided, along with a key to all the known species.

One new species and one newly recorded species of the genus Lasiochira Meyrick, 1931 (Lepidoptera, Oecophoridae) from China

“…All specimens for this study were collected in 2018 from the Hainan and Hubei provinces of China. The descriptive terminology of the anatomical structures follows Wang (2006), Yin et al (2014) and Kristensen (2003). Photographs of adults were taken using a Canon EOS 6D Mark II camera with an EF 100 mm f/2.8L MACRO IS USM lens assisted by the EOS Utility 3.10.20 software.…”

“…No further taxonomic work was published on the genus until Wang (2006) treated the Oecophoridae of China, including the two known species. Yin et al (2014) described six new species, but the entire fauna is known only from China, Korea, and Vietnam.…”

“…The genus Lasiochira is mainly characterized by having a pale, N-shaped pattern consisting of three joined stripes and several small tufts of erect scales on the forewing (Figs 1-3); the gnathos is often pointed and hooked terminally (Figs 4,5,8); the valva usually has dense fine hairs on the distal half (Figs 4,5,8); the cornuti are comprised of multiple short, stout spines or plates (Figs 4,5,8;arrows); the apophyses posteriores are longer than the apophyses anteriores (Figs 6,7,9); the ductus bursae is with sclerotization (Figs 6,7,9); and the signum is transverse, dentate, with a projecting semicircular lobe posteriorly (Figs 6a,7a,9) (Yin et al 2014).…”
