Figs 34̄39 Type material. Holotype . ♀ [on slide, NEFU ], CHINA , Yunnan Province , Kunming City , 10.V.2013 , Xiang-xiang Jin , Chao Zhang , reared from Ceroplastes sp. ( Hemiptera , Coccidae ). Diagnosis. Female. Body largely yellow. Antenna with scape pale yellow, a little darker dorso-distally, pedicel and flagellum brown. Wings hyaline. Head slightly wider than high. Antenna with scape about 4.0× as long as wide; F1 trapezoidal, ventral margin distinctly longer than dorsal margin, without longitudinal sensillum; F1 (ventral length), F2 and F3 subequal in length and width, clava slightly shorter than funicle. Mesosoma with dark setae; mesoscutellum with 3 pairs of setae. Fore wing 2.38× as long as wide. Mesotibial spur slightly longer than corresponding basitarsus. Ovipositor originating from TIII, about as long as mesotibia. Second valvifer 2.45× as long as third valvula. Description. Female. Holotype . Body length 0.96 mm . Head largely yellow with frontovertex orange. Eyes red; ocelli brown. Mandible brown. Antenna with scape pale yellow, a little darker dorso-distally; pedicel and flagellum brown. Mesosoma largely yellow except following dark brown: pronotum medially and extreme sides, median area of the mesoscutum anteriorly, posterior half of notaulus, a small spot on lateral area of the mesoscutum, and anterior margin of mesoscutellum. Mesosomal setae brownish. Wings hyaline. Legs pale yellow. Metasoma mostly yellow, each tergum with faint yellowish-brown patch on both sides sublaterally forming two continuous longitudinal strips that gradually fade distally. Head ( Fig. 34 ), in frontal view, 0.84× as high as wide; frontovertex 0.44× as wide as head. Face with faintly lineolate-reticulate sculpture. Eyes finely setose, each seta about as long as diameter of a facet. Frontovertex with numerous dark setae ( Fig. 34 ). Ocellar triangle with apical angle about 85°. Torulus with upper margin below level of lower eye margin by about own length and separated from mouth margin by 1.3× own length. Mandible with two acute ventral teeth and a short dorsal truncation. Antenna ( Fig. 35 ) with scape (broken) about 4.0× as long as wide, slightly longer than clava; pedicel 1.82× as long as wide, 0.87× as long as ventral length of F1; F1 trapezoidal, ventral margin 1.64× as long as dorsal margin, and 1.83× as long as wide; F2 and F3 equal in length and width; clava 3.04× as long as wide, and 0.92× as long as funicle, clavomeres subequal in length and with the second septum oblique. Flagellomeres with the following number of longitudinal sensilla on one side: 0; 2; 3; 3; 3; 2. Measurements, length (width) of scape, 160 (40); pedicel, 51 (28); F1, 55 (30); F2, 55 (32); F3, 55 (32); clava, 152 (50). FIGURES 34–39. Coccophagus tenebrisetus sp. nov. , holotype ♀: 34, head, frontal view; 35, antenna and complete scape; 36, mesosoma; 37, fore wing; 38, hind wing; 39, metasoma. Dorsum of mesosoma ( Fig. 36 ) faintly reticulate, with sculpture on dark areas more evident. Mesoscutum with median area long, 1.16× as long as wide, and with about 35 setae; each lateral area of the mesoscutum with 3 setae; mesoscutellum 0.76× as long as wide and 0.68× as long as median area of the mesoscutum, and with 3 pairs of setae; axilla with 2 setae. Metanotum 0.71× as long as propodeum. Propodeum composed of a single plate, posteriorly with a small triangular projection medially. Fore wing ( Fig. 37 ) 2.38× as long as wide; marginal setae short; costal cell 0.93× as long as marginal vein, with 3 long setae on dorsal surface distally and a line of setae on ventral surface; submarginal vein with 6 setae; marginal vein with 14 setae along anterior margin; postmarginal vein 0.5× as long as stigmal vein, the latter with a distinct neck and swollen stigma; stigma with sensilla ( Fig. 37 ) arranged in a line. Hind wing ( Fig. 38 ) 5.27× as long as wide; marginal setae 0.5× as long as wing width. Mesotibial spur slightly longer than corresponding basitarsus; metacoxa 1.33× as long as its greatest width and 0.71× as long as metafemur. Measurements, length (width) of fore wing, 871 (366); costal cell, 238; marginal vein, 257; stigmal vein, 35; postmarginal vein, 17.5; hind wing, 733 (139); mesotibia, 297; mesotibial spur, 84; mesobasitarsus, 79; metacoxa, 160 (120); metafemur, 225. Metasoma ( Fig. 39 ) about as long as mesosoma. Ovipositor originating from TIII, about as long as mesotibia. Second valvifer 2.45× as long as third valvula, the latter 1.13× as long as mesobasitarsus. Length measurements of ovipositor, 307; second valvifer, 218; third valvula, 89. Male. Unknown. Host. Ceroplastes sp. ( Hemiptera : Coccidae ). Etymology. The specific name refers to the brownish setae on the mesosoma. Comments. The new species belongs to the ochraceus- group ( Annecke & Insley 1974 ; Hayat 1992 ) and is similar to C. viator Sugonjaev in body colouration. The differences are listed in the key.
