| Summary: | Theileriosis is considered an economically important disease that may decrease productivity and cause a high mortality rate in livestock. Only a few studies have reported <i>Theileria</i> spp., such as <i>T. sergenti</i> and <i>T. buffeli</i>, in recent decades in Taiwan. In the present study, 401 ticks have been collected on Orchid Island in June 2022 and April 2023. Our environmental investigation for SFTSV unintentionally discovered <i>T. luwenshuni</i> in <i>Haemaphysalis mageshimaensis</i> on Orchid Island via PCR. The PCR products were sequenced, and the detected 18S rRNA gene sequences shared a 99.65–99.93% identity with <i>T. luwenshuni</i> sequences from ticks and ruminants in Myanmar and China. Despite the difficulty in clarifying the source of <i>T. luwenshuni</i> within neighboring regions, our findings provide an updated distribution of <i>T. luwenshuni</i> in Asia. This is not only the first time that <i>T. luwenshuni</i> was found in <i>H. mageshimaensis</i> but also the first report of <i>T. luwenshuni</i> on Orchid Island, Taiwan. Our study indicates that ruminants may be at risk of infection. Therefore, further investigations are needed to determine the distribution of <i>T. luwenshuni</i> among ruminants on Orchid Island and in Taiwan. |
