Drepanosticta obiensis

Male : Medium-sized Drepanosticta with a predominantly brown colour pattern. Head with bluish-white labrum and mandibles; the anterior two-fifths of the labrum dark brown. The remaining parts of the head are mostly brownish black. The prothorax is similar to D. moluccana, with no major structural differences. Synthorax brown with distinctly visible pale stripes; compared with D. moluccana, the pale synthoracic markings are more conspicuous. The darker stripe over the metapleural suture is narrower, and the anterior and posterior parts are paler. Legs are dirty yellow with darker rings. Wings are hyaline with brown venation and brown pterostigma. The abdomen is predominantly brown, with segments 8–10 dark brownish black. Segment 2 has a triangular dark marking, while segments 3–7 have pale basal markings. Male anal appendages are diagnostic: the superior appendages are shorter and more slender than in D. moluccana, with the medio-dorsal tooth more distinct and sharper; the inferior appendages are also more slender. Female : Similar to the male but generally paler. The valves and terminal appendages are brownish black and approximately as long as the anal appendages.
