description: <i>Phanoperla huanghuye</i> sp. nov. Figs. 2–10. <b>Adult habitus.</b> General color yellow, patterned with brown (Figs. 2, 3A). Biocellate; head slightly wider than pronotum, with a dark ocellate stigma and a frontal stigma (Fig. 2C). Antenna slender and dark brown, longer than abdomen. Pronotum pale, margins and sutures dark brown, covered with obscure rugosities. Wing membrane subhyaline, veins dark brown (Fig. 4). Coxae pale; apex of femur, apex of tibia and third tarsal segment dark brown. Cercus pale, covered with thick bristles, with about 36 segments. <b>Male.</b> Body length ca. 19.0 mm; forewings length ca. 21.0 mm, hindwings length ca. 19.0 mm <b>(</b> Figs. 2, 4). Tergum 7 with a median patch of sensilla basiconica, number of which varies among individuals, from 1 to about 10 (Fig. 5). Median area of tergum 8 with an oval patch of sensilla basiconica, the sensilla basiconica patch sometimes interrupted medially, divided into two smaller patches. Tergum 9 with a butterfly-shaped patch of sensilla basiconica, the patch about 2X wider than the sensilla basiconica patch on tergum 8. Anterior half of tergum 10 cleft, with a membranous median area; posterior margin of tergum 10 notched, connected with a coniform membrane. Hemitergal lobes curved and contiguous; each hemitergal lobe with an inner hump covered by tiny sensilla basiconica; apical half of each hemitergal lobe strongly compressed from dorsal view, ventroapical margin fringed with a row of long, thick spines <b>(</b> Figs. 5, 6B, 7). Metasternum, abdominal sterna 5–7 each with a median patch of dense bristles (Fig. 2B). Paraprocts unmodified, apices dark (Fig. 6A). Aedeagus (Fig. 8) mostly membranous, slightly curved ventrally, and constricted at mid-length; base of ventral aspect strongly sclerotized, connected with a small oval sclerite (Fig. 8C); dorsal aspect with a subapical lobe; apex membranous, irregular, and concave; basal half of aedeagus covered with spinules on dorsal surface (Fig. 8E); apical half of aedeagus with a continuous patch of stout spines surrounding lateral and ventral surfaces, the spine patch forming a triangular shape on ventral surface (Fig. 8D). <b>Female.</b> Body length ca. 23.0 mm; forewings length ca. 27.0 mm, hindwings length ca. 24.0 mm <b>(</b> Fig. 3A). General color and pattern similar to male. Posterior half of sternum 8 concaved medially, with a sclerotized inner margin, embracing a pale, hexagonal subgenital plate <b>(</b> Fig. 3B). Paraprocts membranous, unmodified. <b>Egg.</b> Egg length ca. 800 µm, equatorial width ca. 680 µm <b>(</b> Fig. 9). Color dark brown, oval in shape; collar dark, wide and short. Chorion covered throughout with uniform, circular punctations. <b>Type material.</b> Holotype: male, China: Fujian Province, Wuyishan City, Xingcun Town, Tongmu Village, near Mt. Wuyishan, unnamed stream (Fig. 10A), 27.7527 N, 117.6882 E, 800m, by light trap (Fig. 10B), July 23, 2019, Yi-Fei Huang, Yu-Xuan Hu, Xiao-Han Ye (ICJUST). Paratypes: 4 males and 6 females, same data as holotype (ICJUST). <b>Etymology</b>. The specific epithet is a combination of surnames of the three collectors, Yi-Fei Huang, Yu-Xuan Hu, Xiao-Han Ye, who generously provided the specimens for study. <b>Remarks.</b> The new species can be distinguished from the two known Chinese congeners by the sensilla basiconica patches on abdominal terga 7–9, the specially modified hemitergal lobes, and the unique aedeagal structure (see fig. 10 in Zwick 1982, and figs. 1–2 in Li &amp; Qin 2016). When compared with all congeners of <i>Phanoperla</i>, <i>P. huanghuye</i> is also distinctive by the combination of following characters: 1) male terga 7–9 with sensilla basiconica; 2) male hemitergal lobes with basal spinulose callus and ventroapical fringe of long, thick spines; 3) aedeagus with a subapical dorsal lobe and a membranous, concave apex; 4) subgenital plate of the female near hexagonal; 5) egg oval with a short collar, chorion covered with circular punctations. These unique characters make it difficult to assign <i>P. huanghuye</i> to any of the species groups defined by Zwick (1982). In addition, CuP of forewings of <i>P. huanghuye</i> is straight basally, rather than curved as commonly found in other congeners (Zwick 1982). Although the three <i>Phanoperla</i> species of China are currently known only from Fujian and Hainan provinces (Fig. 1), more members will certainly be found in other coastal provinces such as Guangdong, Guangxi, and Yunnan provinces considering the known high biodiversity of <i>Phanoperla</i> in the Oriental Region.
