AE34155A5512C15482BAFCE5FC4DFC92.taxon	discussion	Discussion. In Tsuneki (1983), females of this new species key out as D. ruficornis (Cameron, 1889) in having antenna extensively ferruginous; hind femur near base beneath without distinct tooth. But, it differs from D. ruficornis in having: (1) interocular distance at vertex 1.30 × as long as F 1 (in D. ruficornis, interocular distance at vertex as long as F 1); (2) base of T 2 black (in D. ruficornis, base of T 2 ferruginous). This new species differs from D. dinesani Mawadda, Girish Kumar & Sureshan sp. nov., in having: (1) glossy median fovea not present above posterior ocelli on vertex (in D. dinesani sp. nov., distinct glossy median fovea present above posterior ocelli on vertex); (2) apex of clypeus with distinct, strong inverted U-shaped incision medially (in D. dinesani sp. nov., apex of clypeus with distinct but weak incision (flattened inverted V-shaped) medially; (4) clypeus medially weakly raised with indistinct median carina (in D. dinesani basal area of clypeus medially strongly raised with distinct median carina; (5) posterolateral corner of pronotum, mesoscutum and propodeum entirely ferruginous (in D. dinesani, pronotum entirely ferruginous, mark on both sides of mesoscutum anteriorly and propodeum except median part of dorsal side and posterior side ferruginous).	en	Mawadda, N.
