1 Apex of triangular scutellum-like projection of mesonotum narrow, subacute; its surface transversely rugose without distinct elevation; anterolateral angles of pronotum nearly rectangular. Taiwan, Japan, Ryukyu (Figs 5, 11). .................................................................................. T. glabra Heiss & Nagashima, 2008

– Apex of triangular scutellum-like projection of mesonotum wider and rounded, its surface distinctly medially raised; anterolateral angles of pronotum produced. ..................... 2

2 Scutellar ridge as wide as diameter of lateral sclerites and of same height on whole length; antennae longer, about twice as long as width of head; postocular lobes with distinct lateral tubercle; spiracles II–IV ventral and not visible from above, V–VII lateral and visible. China: Guangxi (Figs 6, 9). ......................................................... T. guangxiana sp. nov.
