Thoracostrongylus miyakei Bernhauer, 1943

( Figs. 18–19 )

Type material. Lectotype (male, designated here), in FMNH: Formosa [= Taiwan], Shinchiku [KHnj],-18/VII, 1-30, J. Sonan, K. Miyake.// Ontholestes miyakei Bernh n. sp. [hand writing]// miyakei Bernh Typus, Thoracostrongylus [hand writing, red label]// Chicago NHMus, M. Bernhauer Collection// FMNHINS 3855898, FILED MUSE- UM Pinned [QR code label]. The specimen in poor condition, mounted on the card, genital segment was dissected and mounted on the same card. Body was separated as two parts (a part of head, thorax and elytra another part of abdomen). Both antennae and middle right tibia and tarsus were missing. Hind right leg was separate from the body and mounted on the card. Paralectotype (sex unknown), in TARI: Formosa [= Taiwan], Karenko [= Hualien harbor (ṁẅae)], -19. VII 20–VIII 4., T. Okuni// J. Sonan, K. Miy., M. Yash// Ontholestes miyakei Brnh n. sp. [hand writing label]. The specimen is strongly broken, pinned on a yellowish plastic card. The right antenna, whole abdomen, both hind legs and middle right leg are missing. The segments 3–11 are also missing.

Material examined. TAIWAN: Hualien County: 1 male., Hsinpaiyang (Kbḛ), 07–14.IV.2007, leg. Y.-F. Hsu / Thoracostrongylus miyakei BERNHAUER , det. Schillhammer ’10 ( NHMW) . Taoyuan City: 1 female, Siling (Xö), Fuxing Dist. , 24.6499, 121.4249, 1145m 1~ 3-IX-2019 leg. B. H. Ho by FIT (FSHc) .

Diagnosis. Thoracostrongylus miyakei can be distinguished from T. formosanus in Taiwan by the reddish reflection on the surface of the head, pronotum and elytra, relatively larger eyes, and narrower elytra.

Bionomics. All specimens of T. miyakei were collected from middle elevation mountainous forests. Based on an import of locality name into Google Earth from collection data ( Shibata 1982 and this study), the distributional altitude of this species in Taiwan is from 1080–1700 m. Most specimens were collected by pitfall traps. The specimen from Siling was collected by FIT set in forest. Shibata (1982) reported that a specimen was collected from under fallen leaves near a small stream.

Distribution. Thoracostrongylus miyakei is known from mainland China (Sichuan) and Taiwan. The species is known from northern and central Taiwan: Hualien County, Taoyuan City and Yilan County ( Shibata 1982, Yang et al. 2011 and this study). As the type locality of this species ‘Shinchiku’ included many counties at that time, it’s difficult to determine the exact locality. Another type locality, ‘Karenko’ was a harbor in Hualien County and the locality remains doubtful because this does not fit the bionomics of the species. The specimen from Hsinpaiyang in this study confirms the previous distributional record from Hualien County.

Remarks. Hsinpaiyang is on the Central Cross-Island Highway 142K. The specimen of T. miyakei from Hsinpaiyang indicates that this species is sympatric with T. formosanus in Taiwan, as numerous specimens were collected from the Central Cross-Island Highway 113K to 168K (see ‘Material examined’ under T. formosanus ).
