A new species of Gastrozona Bezzi (Diptera: Tephritidae: Dacinae: Gastrozonini) with an updated key to species from India David, K. J. Hancock, D. L. Zootaxa 2017 4216 1 55 64 6JXWX Schiner Schiner [151,483,1734,1761] Insecta Tephritidae Gastrozona Animalia Diptera 7 62 Arthropoda species soror   Diagnosis.  Gastrozona sororis similar to  G. nigrifemur sp. nov.and  G. fasciventrisin general body colouration and wing pattern. It can be distinguished from  G. nigrifemurby the presence of lateral postsutural yellow vittae in both sexes and narrow anterior apical band not fully covering cell r4+5 and by the spicules of eversible membrane with 2̄3 medial long projections and 4̄5 small lateral projections, unlike the single long medial projection in  G. nigrifemur. It differs from  G. fasciventrisby wing pattern, the posterior apical band separate from the anterior apical band and directed towards the subapical band. It can be differentiated from both species by the oblique wing band from the pterostigma being parallel to the radial-medial band and not sharply incurved towards the wing base. Female genitalia: Oviscape black, 1.35 mmlong, taenia 0.92 mmlong, eversible membrane 1.57 mmlong, spicules sclerotised at proximal end with single broad conical projection, hyaline spicules at distal end of eversible membrane with 2̄3 medial long projections and 4̄5 small lateral projections, aculeus ( 1.50 mmlong) tip trilobed with 4 pairs of preapical setae, preapical steps and smooth lateral margins; two black, club shaped spermathecae with apical papilla.     Materialexamined. 5♀, INDIA: Tripura, I.C.
