Tetraserica quangnam Ahrens, Pacholátko &amp; Pham, sp. nov. is in shape of metatibia similar to Tetraserica bartolozzii Ahrens, 2023 . The new species, however, differs by the less strongly truncated metatibia of which the ventral terminal spine is situated not at middle of the ventral margin but at posterior third of metatibial ventral margin; furthermore, the shape of parameres differs distinctly between the both species: The right paramere is in the new species strongly hooked at apex, while the left parameres is curved evenly ventrally instead of being reflexed dorsally (as in T. bartolozzii).</p><p>Etymology. The new species is named after its occurrence in the Quang Nam province (noun in apposition).</p></div>	https://treatment.plazi.org/id/03FB3D2FFFBAFFCBF088F8A8E096F91F	Public Domain	No known copyright restrictions apply.

Tetraserica schnelli Ahrens, Pacholátko &amp; Pham, sp. nov. differs from T. semidamaidiensis Fabrizi, Dalstein &amp; Ahrens, 2019 by the entirely straight left paramere (lateral view), and the longer and less strongly curved right paramere (lateral view) of which the preapical lateral tooth is less distinct and its mesal lateral tooth is directed distally instead of basally (dorsal view) (as in T. semidamaidiensis).</p><p>Etymology. The species is dedicated to Michael Schnell (Museum Koenig Bonn) who helped with the construction of light traps which are in use in our Vietnam biodiversity project (noun in genitive case singular).</p></div>	https://treatment.plazi.org/id/03FB3D2FFFA0FFD0F088FEB8E064F823	Public Domain	No known copyright restrictions apply.
