A Checklist of the Olethreutini Obraztsov, 1946 (Lepidoptera: Tortricidae) of Taiwan, with the Distribution in Mainland China

TL;DR

This paper provides a checklist of 102 species of leaf-roller moths in Taiwan and their distribution in mainland China.

Contribution

It reports two new genera and six new species for China, and two new genera and eighteen new species for Taiwan.

Findings

Thirty-five genera and 102 species of Olethreutini moths were documented from Taiwan.

Nine species previously endemic to Taiwan were found for the first time in mainland China.

The study provides synonymies and geographic distributions for each species.

Abstract

This study examined specimens of the tribe Olethreutini collected from more than 60 sites in Taiwan between the years 1921 and 2005, listing 102 species in 35 genera. The specimens are deposited in the National Museum of Natural History, Washington, DC, USA (USNM), and the McGuire Center for Lepidoptera and Biodiversity, Florida Museum of Natural History, University of Florida, Gainesville, Florida, USA (FSCA). At the same time, the distribution of these species in mainland China was examined, and the research specimens are deposited in the Insect Collection, Nankai University, Tianjin, China (NKU). This study makes up for the shortcomings of the previous research on the Chinese tortricids, which is conducive to the comprehensive completion of the systematic research of Chinese fauna and also provides basic data for the systematic research of the world’s leaf-roller moth.

Thirty-five genera and one hundred and two species of the tortricid tribe Olethreutini documented from Taiwan are listed, two genera and six species of which are newly recorded for China and two genera and eighteen species of which are newly recorded for Taiwan. Nine species are recorded in the mainland of China for the first time, which were endemic to Taiwan before this study. The local monographs of China and references are summarized with the examined specimens. The synonymies and geographic distribution in China are provided for each species, and a list of examined specimens is provided when applicable.
