Diagnosis. Gastrozona fasciventris is similar to G. nigrifemur sp. nov. and G. soror in general body colouration and wing pattern. It can be distinguished from G. nigrifemur sp.nov. by the anterior apical band not confluent with vein R4+5 throughout its length and the posterior apical band distinctly fused with the anterior apical band plus, in the female, the distinct lateral postsutural yellow vittae and presence of a serrated lateral margin of the aculeus tip. G. soror can be separated by wing pattern, the posterior apical band being free from the anterior apical band and directed towards the subapical band. This species was well illustrated and described by Hardy (1973) and Hancock & Drew (1999) except for male and female terminalia. Though Hardy (1973) provided the illustrations of male and female genitalia, eversible membrane sculpturing and phallic characters were not evident, hence a brief account of postabdominal structures of male and female are included here.

Female genitalia: Oviscape black, 1.5 mm long, taeniae well developed (1.1 mm), eversible membrane (1.7 mm long); sclerotised spicules with single medial projection at the proximal end, spicules at distal end of eversible membrane hyaline with 1 medial long projection and small 4̄5 lateral projections, aculeus (1.50 mm long) tip trilobed with 4 pairs of preapical setae, preapical steps and serrated lateral margins; two black, club-shaped spermathecae with apical papilla.

Male genitalia: Epandrium sclerotised, with well developed black, opaque, cap-like proctiger larger than epandrium, lateral surstylus narrow with posterior lobe, broad, longer than anterior lobe, medial surstylus shorter than lateral surstylus with thick prensisetae. Epandrium and surstyli distinctly bulb-shaped in posterior view. Phallus (2.6 mm long) with sclerotised glans of phallus, acrophallus with paired semitubular lobes, praeputium smooth, preglans lobe absent. Hypandrium C-shaped, phallapodeme broadened posteriorly with vanes fused with lateral sclerite.
