( Figures 4–6 ) Diagnosis Aedeagal median rod dorsosubapically with small triangular projection in addition to prominent subbasal dorsal projection, apically hook-like bifurcated ( Figure 6 ). Description Head. Eye brown-red. Ocellar triangle dark brown. Postocellar setae longer than interfrontal setae, slightly behind top of vertex ridge. Frons, face, and gena all brown. Pedicel brown, with strong seta dorsally and several setulae near anterior margin; first flagellomere grey-yellow. Facial carina slightly developed. Clypeus medially orange brown, laterally dark brown. Palpus grey-yellow except basal grey-black part, rod-shaped, with several stout setae on lateral margin. Vibrissa prominent; other orals small. Postgena dark brown. Figures 4–6. Apsiphortica longiciliata Cao and Chen , sp. nov. , „ . (4) Epandrium, cercus, and surstylus, lateral view. (5) Surstylus and 10th sternite, ventral view. (6) Hypandrium, gonopod, paramere, aedeagal median rod, and aedeagal apodeme, lateral view. For abbreviations see Figures 1–3. Scale bars: 0.1 mm. Thorax. Brown-yellow, with four narrow black stripes on scutum and a few dark brown patches on pleura. Postpronotal lobe paler, with a long and two to four small setae. Acrostichal setulae in about 10 irregular rows. Scutellum dark brown except grey-brown posterior margin; basal scutellar setae divergent; apicals cruciate. Katepisternal setae two. Wing. Hyaline; veins grey-yellow. C 1 setae less differentiated. Basal medial-cubital crossvein present. Costal vein with 21–22 minute spinules on ventral surface between R 2+3 and R 4+5 . R 2+3 slightly curved to costa at tip; R 4+5 and M 1 distally slightly convergent. Halters white. Legs. Entirely yellow. Fore femur with two to three rows of setae on posterodorsal to posteroventral surface. Preapical dorsal seta present on tibiae of all legs. Apical seta present on mid tibia. Fore tarsus with two to four strong setae on basoventral surface. Mid tarsus ventrally with two rows of minute cuneiform setulae; hind tarsus lacking minute cuneiform setulae; fore first tarsomere shorter than the rest combined; mid and hind first tarsomeres longer than the rest combined. Abdomen. Tergites dark brown to black; second to fourth each with broad, dark brown band on posterior margin. Sternites pale yellow. Male terminalia. Epandrium strongly protruded at anteroventral corners, with about 27 setae near posterior margin and pubescence except anteroventral margin ( Figure 4 ). Surstylus apically protruded, with a few setulae on apical margin ( Figure 4 ). Cercus separated from epandrium, small, somewhat semicircular, nearly entirely pubescent and densely setigerous ( Figure 4 ). Tenth sternite laterally fused to surstyli, with small pubescent median piece and a pair of elongated lateral arms apically contiguous to base of gonopod ( Figures 5, 6 ). Hypandrium plate-like anteromedially ( Figure 7 ). Parameres slightly curved ventrad, basally articulated with aedeagal apodeme ( Figure 6 ). Gonopods fused to each other, forming posteromedian plate, anteriorly broadened, posterolaterally contiguous to posterior ends of hypandrium and apices of epandrial anteroventral elongations ( Figure 6 ). Aedeagal outer membrane posteriorly connected to gonopod, with numerous sclerotized small pieces ( Figure 6 ). Aedeagal median rod basally articulated with aedeagal apodeme ( Figure 6 ). Aedeagal apodeme long rod-like ( Figure 6 ); ventral branches of aedeagal apodeme apically fused to each other ( Figure 6 ). Measurements.
