Figures 1–18
Type material. Holotype ♂, China, Jiangxi Province, Jiujiang City, Wuning Country, Yangzhou Town, 27–30 July, 2020, coll. Ye Xu, Wang Yuan, by light trap. Paratypes. 27♂♂, same data as holotype; 20♂♂, China, Jiangxi Province, Jiujiang City, Wuning Country, Yangzhou Town, 27–30 June, 2021, coll. Ye Xu, Liu Guoshun, by light trap.
Description. Body length: male 3.3–3.5 mm, female 3.3–3.6 mm
Ground color light yellow (Figs 1–4). Crown and pronotum anteriorly with irregular milky to creamy yellow patches (Figs 1, 3). Eyes dark (Figs 1–4). Ocelli surrounded by irregular light brown patches (Fig. 4). Face and antennal segments light brown (Fig. 4). Mesonotum slightly darker than head and pronotum (Figs 1, 3). Fore- and hindwing subhyaline, vein distinct (Figs 1, 2, 5, 6). Legs pale yellow except pro- and mesothoracic tibiae and tarsi brown (Figs 1, 2).
2S apodemes extending to middle of segment IV (Fig. 7). Male pygofer bearing 6–8 rigid setae in posterior margin, ventral margin inflexed with 5–7 tiny fine setae, ventral pygofer appendage tapered to a narrow, pointed tip, smooth, extended to ventral margin of lobe, apex curved caudo-dorsad, slightly sinuate in apical half (Fig. 8). Subgenital plate narrow at base, somewhat broadened toward middle, apex tapped and divergent from ventral margin of pygofer lobe; marginal setae (45–50) uniseriate, occupying nearly whole length of dorsal margin, macrosetae (13–14) arising near broadest of plate, sharply terminated, feeble microsetae (6–10) inconspicuous (Figs 8, 9, 17). Aedeagus slim, S-shaped, preatrium longer than shaft in lateral view, shaft curved dorsad and broader middle, without dorsal apodeme, gonopore ventrad at apex, large (Figs 8, 12, 13). Style sinuate, broad at base, sharply pointed apically, dentifer bearing about 12–13 tiny teeth preceded by 7–8 fine setae and few sensory pits (Figs 15, 16). Connective lamellate, slightly elongate, longer than wide (Fig. 18). Anal tube appendage weakly developed, vestigial (Figs 8–11).
Etymology. The species name refers to the locality of the holotype, Wuning County.
Remarks. The new species is similar to O. okubella Matsumura and O. convoluta Yu &Yang in aedeagal shape (Figs 8, 12). However, it differs from O. convoluta in having the face light brown (Fig. 4) (face dark in O. convoluta), and from O. okubella (Matsumura) in having the aedeagus shaft smooth (Fig. 12) (shaft with lateral teeth subapically in O. okubella). Furthermore, it differs from these two previously described species in having the male pygofer ventral appendage extended to the margin of the pygofer lobe and the anal tube appendage poorly developed and lobe-like (Fig. 8) (ventral appendage weakly developed, not extended to pygofer lobe, and anal tube appendage elongate in O. okubella (Matsumura) and O. convoluta Yu &Yang).
Distribution. China (Jiangxi).
