The dorsal lobe of the right paramere is in T. xinba Ahrens &amp; Pham, sp. nov. smaller / shorter being subequal to ca 1 / 5 of the length of mesoventral apical apophysis of phallobase (instead of 1 / 3 as in T. tonkinensis), and the ventral lobe of the right paramere is also much shorter (both in lateral view). The right paramere is in T. xinba Ahrens &amp; Pham, sp. nov. more evenly curved, lacking the submesal blunt tooth on its dorsal margin. From the also similar T. phamanhi Pham &amp; Ahrens, 2023, the new species differs by the unsplit left paramere and the much longer and almost evenly wide mesoventral apical apophysis of phallobase. The latter is in T. phamanhi shorter and distinctly evenly narrowed from the base towards its apex. From T. appendiculata Fabrizi, Dalstein &amp; Ahrens, 2019, T. xinba Ahrens &amp; Pham, sp. nov. differs by the in apical half much wider mesoventral apical apophysis of phallobase, which is, however, in basal half distinctly narrower than in T. appendiculata, by the much larger and more convexly pronounced basal lobe of the right paramere, and the in apical half more strongly curved left paramere.</p><p>Etymology.</p><p>The new species is named after its type locality, Xinba village (noun in apposition).</p></div>	https://treatment.plazi.org/id/5E31F8A67F0C5AFE930B18BB1762895F	Public Domain	No known copyright restrictions apply.
