description: <i>Togoperla flinti</i> sp. nov. (Figs. 1–2, 7A) <b>Diagnosis</b>. Males of this species are distinguished by head with a large dark brown marking surrounded by a pale margin around the compound eyes and lateral frons and legs with dark brown femorotibial joints and tibial apex. The aedeagal sac is mostly covered by the armature before the bald swollen apex with a pair of closely set lobes. <b>Male</b>. Forewing length 25.0– 25.4 mm. General color brown (Fig. 7A). Head with large dark brown median marking surrounded by a pale margin around the compound eyes and lateral frons. Compound eyes dark; antennae yellow brown. Pronotum rugose and dark brown, anterior margin convex and wider than posterior margin, posterior corners obtuse (Fig. 1A); wings light brown and veins darker; legs yellow to yellow brown with dark brown femorotibial joints and tibial apex, tarsi dark brown (Fig. 1E). Abdomen brownish. <i>Terminalia</i>. Mid-posterior margin of tergum 5 produced in a dark, fan-shaped, emarginate lobe. Terga 6-9 with pale brown to brown medial sclerites (Fig. 1B). Hemitergal process forward of basal callus longer than callus, apex wide and obtusely rounded in basal and lateral view, basal callus bearing sensilla basiconia (Figs. 1C–D). Aedeagus with basal third quadrate, medially constricted and apically gradually enlarged: aedeagal tube basally with a large tongue-shaped lobe in dorsal aspect, across ca. 2/3 width of base, and medially with a pair of small, bare, basolateral lobes; apically with a pair of closely set paramedial lobes; armatures of sac present most surface of sac except for bald basal part and apical lobes, dorsal armature medially interrupted by narrow membrane (Fig. 2). <b>Variations</b>. The color pattern and main structures everted aedeagus are consistent, but the narrow medial membrane between the dorsal armature of sac absent in one paratype and obscure in another male. <b>Type material.</b> Holotype: male (CAUC), China: Anhui Province, Yuexi County, Dabie Mountains, Yaoluoping village, light trap, 2011.VII.26–27, Xuankun Li. Paratypes: 2 males (CAUC &amp; HIST), Hubei Province, Yingshan County, Caopan Town, Dabie Mountains, Taohuachong Forest Park, light trap, N 30°57.606’, E 115°45.426’, 634 m, 2014. VI.25. <b>Etymology</b>. The species is named after the late Dr. Oliver S. Flint, Jr. at the Smithsonian Institution, Washington, D.C., U.S.A., in recognition of his taxonomic contributions to major groups of aquatic insect. <b>Distribution</b>. China, known from the Dabie Mountains in Anhui and Hubei provinces. <b>Remarks</b>. The new species is similar to <i>T. canilimbata</i> (Enderlein, 1909), a widespread species known both from China and Vietnam, but they differs in leg pattern: the femora of <i>T. flinti</i> sp. nov. have a wide pale band basally, while those of <i>T. canilimbata</i> have narrow yellow bands medially. It differs also in the aedeagal sac that has two narrowly separated paramedial lobes at apex (Fig. 2). In <i>T. canilimbata</i>, the apex of sac bears a pair of widely separated lateral lobes and a long oppositely directed median lobe (Fig. 3 &amp; figs. 5–6 in Stark and Sivec (2008)). <i>T. flinti</i> sp. nov. has identical femoral color pattern and similar lateral outline of everted aedeagus to <i>T. fortunati</i> (Navás, 1926) presented below, but the new species can be easily separated by shorter hemitergal lobe and presence of two dorsolateral lobes of aedeagal tube.
