description: <i>Brachineura physiphora</i> Jiao &amp; Bu, sp. nov. (Figs 7–9) Diagnosis. The new species is characterized in the genus <i>Brachineura</i> by the uniqueness of aedeagus ventrally with a blister-like protrusion in the sub-apex and dorsally with a finger-shaped structure. It is similar to <i>B. fungicola</i> Mamaev by the elbow-shaped gonostylus (Fig. 8). However, the new species differs by aedeagus ventrally with a blister-like protrusion in the sub-apex and dorsally with a finger-shaped structure in the middle, and gonostylus distinctly longer than half of the length of gonocoxite (Fig. 8), while <i>B. fungicola</i> has aedeagus only with a smaller prominence in the apex and gonostylus approximately as long as half the length of gonocoxite. Description. Adult. Body colour yellow brown. Body length 0.90–1.00 mm; wing length (measured from the base) 0.95–1.05 mm; wing width 0.40–0.50 mm (<i>n</i> =3). Head. Eye bridge 2 facets long in the middle of vertex. Male 3rd flagellomere as <i>sphaerica</i> in Fig. 1, with the node 2.30–2.40 times as long as wide and the neck 1.00–1.10 times as long as wide, 0.19–0.20 times length of node. Others as <i>B. sphaerica</i>. Thorax. Wing 2.40–2.50 times as long as wide. Others as <i>B. sphaerica</i>. Abdomen. second through sixth sternites with an irregular but mostly double, posterior row of setae; eighth sternite sub-rectangular. Others as as <i>B. sphaerica</i>. Male genitalia (Figs 7–9). Gonocoxite slender, with mediobasal lobes undeveloped and reduced to two separated setae and a pair of closely set setae, each inserted in a small, smooth and sclerotized prominence; gonostylus elbow-shaped, distinctly longer than half length of gonocoxite, covered with a few setae and dense microtrichiae, with a short setae located apically on the inner side, toothed apically; cerci separated with a wide depression forming two broad lobes with a few long lateral setae; hypoproct distinctly longer than cerci, emarginated deeply and widely with a U-shaped depression forming two slender lobes; aedeagus stout and sub-cylindrical, distinctly longer than gonocoxite, but distinctly shorter than 1.5 times the length of gonocoxite, ventrally with a blister-like protrusion in the sub-apex and dorsally with a finger-shaped structure in the middle. Female genitalia unknown. Material examined. Holotype. &amp;male;. China, Yunnan, Simao (now as Pu’er), Caiyang River Nature Reserve, Luoluoxinzhai Mountain (22.48°N, 100.58°E; elev. 1500 m), 27. V.2000, leg. Wenjun Bu, Malaise trap, NKUCecid. No. BBSS001. Paratypes. 2&amp;male;, same data as holotype, NKUCecid. No. BBSS002–003. Distribution. China (Yunnan). Etymology. The specific name <i>physiphora</i> means the sub-apex of aedeagus ventrally with a blister-like protrusion.
