Distribution. China (Hubei, Sichuan, Shaanxi, Gansu, Henan). New to Shaanxi, Gansu, and Henan.
Diagnosis. In general appearance, T. acerosusis similar to T. aduncatusYang, Zhou & Schillhammer, 2011, T. fujianensisYang, Zhou & Schillhammer, 2011, and T. diaoluoensisYang, Zhou & Schillhammer, 2011, but it can be recognized by the sharply pointed tip of aedeagal median lobe.
Remarks. The apical portion of the median lobe and the paramere are subject to some variability (Figs 3- 14). This may be observed not only in populations from different localities but also within one population. A closer inspection of the types of T. baoxingensisand T. acerosusrevealed that this is the case here as well and that both species are conspecific. Figures 7-14.
