Female, habitus. Scale bar: 5.0 mm. Diagnosis. General body coloration of this species is brownish black with yellow markings. It can be distinguished from other Distoleon species by white longitudinal stripes on both wings. Moreover, the forewing has distinct cubital mark and distal part with four brown spots, two distad hypostigmatic cell, and two at initial branching point of MA. Distal part of hind wing has an L-shaped marking at marginal fork of MP1, but with brown spots distad hypostigmatic cell indistinct ( Fig. 3 ). Measurement ( ♀ n=1; unit mm). Forewing length 32.5, width 5.9; hind wing length 31.4, width 5.2; body length 25.5. Re-description. Head. Face yellow with a black stripe around the base of antennal toruli; interantennal marking distinct, yellowish white, with black setae on each side. Frons yellow, covered with short black setae ( Fig. 2B ). Vertex raised, dark brown, with two longitudinal yellow stripes, posterior stripe interrupted at middle, covered with short brown setae. Occiput with crown-shaped yellow marking ( Fig. 2C ). Antennae longer than length of head and prothorax combined; clavate; toruli yellowish white; scape and pedicel shiny black but orange apically; flagellomeres annulated with brown and whitish rings, covered with short black setae except a few basal segments with white setae ( Figs 2B , 4C ). Maxillary and labial palps, labrum, clypeus, gena and face yellow; labrum with brown, erect setae; clypeus with long yellowish brown and black setae. Labial palpi with distal palpomere spindle-shaped with an acute apex, palpimacula brownish, small and circular, narrowed basally ( Figs 2B , 5A ). FIGURE 2. Distoleon sambalpurensis Ghosh. A.
