Diagnosis. Thoracostrongylus formosanus can be distinguished from T. miyakei from Taiwan by the absence of a reddish reflection on the surface of head, pronotum and elytra, relatively smaller eyes and wider elytra.

Bionomics. Based on an import of locality name into Google Earth from collection data ( Shibata 1982, Yang et al. 2011, this study), the distributional altitude of this species in Taiwan is from 700–2600 m. Specimens of T. formosanus were mainly collected by pitfall trap or flight interception trap. Some specimens were collected from the surface of fresh mammal dung or carrion.

Distribution. Thoracostrongylus formosanus is known from mainland China (Sichuan, Zhejiang, Hunan, Fujian and Hubei) and Taiwan. The species is widespread on Taiwan island and is at present known from Hualien County, Nantou County, Taichung City and Yilan County ( Shibata 1982, Yang et al. 2011, this study).
