Bai, Xiaoshuan, Heiss, Ernst & Cai, Wanzhi, 2017, A new genus and three new species of apterous Carventinae from China (Hemiptera: Heteroptera: Aradidae), Acta Entomologica Musei Nationalis Pragae (suppl.) 57 (1), pp. 35-46 : 41

Key to Taiwanaptera species

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.

– Scutellar ridge distinctly narrower than diameter of lateral sclerites, depressed at middle; antennae about 1.8–1.9 times as long as width of head; postocular lobes granulate; spiracles II–III ventral and not visible from above, IV sublateral and V–VII lateral and visible. China: Yunnan ( Figs 7 , 10 ). .............................................................. T. montana sp. nov.
