Tergum 10 is characterised by a sclerotised trapezoidal plate, featuring drop-shaped lateral bars and subtriangular transverse bars that bear long hairs. The lateral projection terminates in a downward-pointing spine. The cercus includes an apical</p><p>The epiproct curves sharply upward, forming a hook shape with a blunt tip. Subanal lobes exhibit ventral furrows. In females, sternum 7 features a subgenital plate with apical lobes and a longitudinal bar. Sternum 8 with a wavy, sclerotised transverse postgenital plate.</p><p>Description</p><p>Adult habitus (Figure 1 (a)). Head brown, wider than pronotum; compound eyes black; antennae and dark brown. Pronotum brown, rectangular, all corners obtuse and with dark brown symmetrical</p><p>Wings grey brown, with brown veins; legs brown. Abdomen and terminalia brown.</p><p>Male (Figures 1, 2, 4 (a–c)). Fore wing length 6.5–6.8 mm, hind wing length 5.5–5.8 mm (Tergum 9 moderately sclerotised, except for a large, weakly sclerotised area in the middle a small, strongly sclerotised, rounded and upraised process located at mid-posterior margin.</p><p>9 approximately as long as wide, basally with tongue–like vesicle bearing dense hairs, apically a short, blunt, triangular subgenital plate. Tergum 10 with a distinctly sclerotised subtrapezoidal central plate accompanied by a pair of drop-shaped lateral bars; transverse bars distinctly sclerotised and narrowly separated in the middle, with a cluster of long, black the lateral portion, extending to the inner side of tergum 10; lateral projection paired,</p><p>starting from a small, rectangular basal plate and ending in a downward-pointing triangular when viewed laterally.

Fore wing length 7.2–8.0 mm, hind wing length 6.2–6.9 mm (n = 4). generally similar to male. The posterior margin of sternum 7 produced into a subrectangular pigmented subgenital plate with a middle notch forming a pair of lobes; the posterior area a longitudinal dark bar. Sternum 8 features a wavy, sclerotised, transverse postgenital plate located the posterior half of the segment.</p><p>HISTORY HISTORY</p><p>Remarks</p><p>The new species is not confidently assigned to any of the currently recognised species groups genus Rhopalopsole, as it shows only partial agreement with the morphological features of the R.</p><p>group and the R. vietnamica group (western assemblage). The new species shares similarities Rhopalopsole shimentaiensis Yang, Li and Zhu, 2004, which is found in Guangdong, particularly shape of the central plate and transverse bars of tergum 10, as well as the presence of an apical the cercus. However, the new species can be easily distinguished from the latter by the following a rounded process on tergum 9, a narrow hook-like epiproct with a blunt tip, and a lateral projection</p><p>HISTORY mid-posterior spine; the epiproct is wide and ends in a truncate tip; and the lateral projection on ends in a truncate tip.</p><p>Distribution</p><p>As of now, the newly identified species has been found exclusively in the Guangxi Zhuang</p><p>Region, China.</p><p>Key to the males of Rhopalopsole from Guangxi, China</p><p>1.
