Revision on subfamily Scelimeninae (Orthoptera: Tetrigidae) from Taiwan and altitudinal distribution of Tetrigidae / 台灣刺翼菱蝗亞科(直翅目:菱蝗科)之分類修訂及菱蝗海拔分布

碩士 / 國立中興大學 / 昆蟲學系所 / 98 / Scelimeninae is a worldwide-distributed subfamily, comprise of 27 genera and 246 species. It was recorded 4 genera and 5 species from Taiwan before. This study started from August, 2008 to May, 2010. There were totally 311 collecting sites and 938 specimens recorded, and 130 specimens from colleagues. There were 434 specimens examined from Lab. Of Insect of Taxonomy, Department of Entomology, National Chung Hsing University. There are totally 1502 specimens could used for this study. The characters revised in this study including the relative position of eyes and pronotum, ratio of vertex and eye in width, producing spines of pronotum, ratio of PL2 and PL1, ratio of valvas of female ovipositor etc. According to these characters, we record 5 species- Eucriotettix oculatus transpinosus Zheng, 1993、Platygavialidium formosanum (Tinkham, 1936)、Criotettix bispinosus (Dalman, 1818)、Thoradonta nodulosa (Stål, 1861)、Loxilobus formosanus Günther, 1941. Thoradonta nodulosa (Stål, 1861) is a new record species in Taiwan and the genus Thoradonta Hancock, 1909 is also newly record . Eucriotettix magnus (Hancock, 1907) is not recorded in this study. The habitat characters were also discussed in this study; we also recorded mosses and lichens in the habitat. We also use 19 Tetrigidae species to discuss the altitudinal distribution. The two species of Tetriginae- Formosatettix arisanensis and F. karenkoensis could distributed at middle and high altitude. Scelimeninae and other Tetrigidae species are mainly distributed at low altitude (< 1000m). There were a little specimens of Eucriotettix oculatus transpinosus and Platygavialidium formosanum collected from middle altitude. The other two altitudinal distribution collection of Tetrigidae were at Provincial Highway No. 8 and Dasyueshan forest road. The former had 21 collecting sites and 64 specimens, which belonged to 5 species, 5 genera. The latter one had 19 collecting sites and 122 specimens, which belonged to 6 species, 6 genera. It was proved that F. arisanensis and F. karenkoensis only distributed at middle and high altitude. Hind wing reduced of these two species could be the adaptive characters of high altitudinal species. However, the other species in the same genus- F. formosanus mainly distributed at low altitude.The adaptive characters of this genus deserved to further study. The other species, Tetrix sp., which collected from Provincial Highway No. 8, only distributed over 2000m, maybe one new record of high altitudinal distributed species.
