Bactrocera (Zeugodacus) anala Chen et Zhou , sp.nov
( Figs 1–7 View FIGURES 1 – 7 )
Description. Male ( Figs 3–4 View FIGURES 1 – 7 ). Body length 6.1mm; Wing length 6.4mm.
Head. Frons ( Fig.1 View FIGURES 1 – 7 ) yellow to fulvous, with indistinct middle blackish mark and black spots at bases of setae; frons about 1.8 times as long as wide, narrower than eye in dorsal view. Lunule dark brown. Ocellar triangle and vertex black. Face ( Figs 1, 5 View FIGURES 1 – 7 ) yellow to fulvous with two blackish round spots in antennae grooves, the distance between the two spots distinctly shorter than their diameter. Parafacial and gena yellow to fulvous, gena with vague black area under lower margin of eye. Occiput dark brown to black, yellowish along eye margin; occipital row of setae present. Antenna with scape and pedicel fulvous, flagellomere 1 fulvous with apex and anterior part slightly darker and about 4.0 times as long as pedicel; arista bare, black with yellowish base. Head setae black: 3 frontals, 1 orbital, 1 medial vertical, 1 lateral vertical, 1 genal.
Thorax. Scutum ( Fig.6 View FIGURES 1 – 7 ) black with two narrow lateral postsutural yellow vittae extends well before the level of intra-alar setae, and one long narrow median postsutural yellow vitta that extend well before prescutellar acrostichal setae and is about as long as lateral postsutural vittae. Postpronotal lobes entirely yellow. Pleura predominantly black with following yellow areas: notopleural callus, anepisternal stripe, anatergite, katatergite. Scutellum with two lateral yellow marks, narrow black basal band and a black medial mark extending from base to apex. Mediotergite entirely black. Scutellum with basal as well as apical setae. Other thoracic chaetotaxy: 2 notopleural, 1 postsutural supra-alar, 1 postalar, 1 intra-alar, 1 anepisternal, 2 scapular, 1 prescutellar acrostichal setae present. Wing ( Fig. 2 View FIGURES 1 – 7 ) hyaline in ground color; costal dark brown band confluent with vein R2+3, having an isolated apical dark brown spot; anal streak dark brown and broad, extending to posterior margin; cells bc and c colourless. Legs yellow to fuscous; fore femur with apical 3/4 black; mid with apical 1/2 black and hind femora with apical 1/3 black; fore and hind tibiae dark brown to black, mid tibiae fuscous with apical 1/3 darker; tarsi yellow to fuscous (apical 4 segments darker); mid tibia with black apicoventral spur.
Abdomen ( Fig. 7 View FIGURES 1 – 7 ). Oval in outline, generally black. Tergite 1 black, with a very narrow vague yellow to fulvous band on posterior margin; tergite 2 black, with a broad, middle concave yellow to fulvous band on posterior margin; tergites 3 and 4 black; tergite 3 with pecten on each side of posterior margin; tergite 5 black, with a very narrow vague yellow to fulvous band on posterior margin and a pair of oval dark shining spots at middle area.
Female. Unknown.
Etymology. The specific epithet refers to the wing anal streak.
Type Data. Holotype 3 ( IZCAS), China: Yunnan: Xishuangbanna, Mengsong , Benggangxinzhai 1750m, N22º09'34'' E100º33'47'', 11 July 2011, Zhao Zhe GoogleMaps .
Distribution. China: Yunnan (Xishuangbanna).
Host. Unknown.
Remarks. This species is somewhat similar to B. (Z.) adusta (Wang et Zhao) from Sichuan. These two species may be characterized by scutum entirely black except for 3 postsutural yellow vittae, and scutellum with two lateral yellow marks and a black medial mark extending from base to apex. This new species, however, can be easily differentiated by the following characters: 1) scutellum with 2 pairs scutellar setae, 2) wing with anal streak dark brown and broad, and 3) the distance between the two facial spots much shorter, being about 0.5 times their diameter. This species is also similar to B. (Z.) biguttata (Bezzi) , but can be differentiated from the latter by the following characters: 1) scutellum with 2 pairs scutellar setae, 2) wing with anal streak dark brown and broad, and 3) wing with a slightly smaller and isolated apical spot.
