Based on the absent of tympana, similar vein patterns of wings in both sexes, and developed and bifurcated ectoparamere, this new species can be assigned to  Trigonidium . The new species shares similar features of epiphallus (broad, concave, serrated lateral lobe, and tapering at the end) and ectoparamere (short and bifurcated) with  Trigonidium cicindeloides Rambur, 1838,  Trigonidium nigripes Yuan, Ma &amp; Gu, 2022, and  Trigonidium japonicum Ichikawa, 2001, but new species with narrower lateral lobe in lateral view, and can be distinguished from these species by the coloration (colored dark of profemur, mesofemur, and abdomen; colored light of protibia and mesotibia; and colored dark and light of metafemur). The new species shares similar coloration (black profemur, mesofemur and abdomen, light protibia, mesotibia and most part of metatibia, and the tegmina dorsal area mostly white, lateral area black) with  Trigonidium rubrumoculum He &amp; Ma, 2022, but  T. rubrumoculum has different ectoparamere possessing long and thin upper branch and epiphallic lateral lobe not serrated of its inner margin, and  T. rubrumoculum has red compound eyes.</p></div>	https://treatment.plazi.org/id/9C20878CDC2517446AED86FCFD00F3D0	Public Domain	No known copyright restrictions apply.

Vertex wide and flat, with sparsely setae, posterior with two light stripe; frontal wide, not protruding in the dorsal view, slightly wider than antennal scape; compound eyes large with irregular dark banding, protruding in dorsal view; ocellus invisible; antennal scape cylindrical with short hairs, pedicel cylindrical, flagellum longer than body length; clypeus wide; maxillary palp five segments, terminal segment long with transverse end; labial palpi three segments, the terminal segment enlarged with transverse end.

Based on large oval outer tympana and narrow inner tympana, the lateral lobe of epiphallus with narrow apical projection and the ectoparamere partially join with the epiphallus, this new species can be placed in  Svistella .  S. prominens sp. nov. can be distinguished from  Svistella rufonotata (Chopard, 1932),  Svistella dubia (Liu &amp; Yin, 1993),  Svistella bifasciata (Shiraki, 1911),  Svistella argentata Ma, Jing &amp; Zhang, 2019, and  Svistella yayun He, 2024 by smaller ectoparamere (invisible in lateral view). Generally, the new species is similar to  S. anhuiensis, and both are found in the same area, but  S. prominens sp. nov. possesses the body with darker color,  S. anhuiensis with golden head and pronutum, light legs and abdomen. In addition, the genitalia is similar to  S. anhuiensis,  Svistella fallax He, Li &amp; Liu, 2009, and  Svistella wuyong He, 2021 in lateral view, but  S. prominens sp. nov. has obvious semicircular processes at the inner margin of the epiphallic lateral lobes in dorsal and ventral view (Fig. 6 A, C), while  S. anhuiensis,  S. fallax, and  S. wuyong has smooth inner margin without processes.</p></div>	https://treatment.plazi.org/id/9C20878CDC2017416AED81DEFBA7F5FE	Public Domain	No known copyright restrictions apply.
