Metascutal triangle with posteromarginal flange extending to or over anterior margin of metascutellum ( Figs 11, 12 ); tergite I with median minute setal pair arising anterior to reticulate area ( Fig. 7 ); tergites III–VIII with reticulation in front of antecostal ridge strongly developed ( Fig. 5 )........................................................................ 2
