Remarks.

This species is similar to Thaioneura nigrilinea on external appearance and genital structures, but can be distinguished by the aedeagal shaft without processes, the longer preatrium (Figs 19, 20) and the more slender, less curved pygofer dorsal appendage (Fig. 14).

Etymology.

The specific name is derived from the Latin word “sinuate” (curved in and out), referring to the sinuate aedeagal shaft in lateral view (Fig. 19).
