The mature nymph measures between 9.5 to 11.5 mm in body length and 9.0 to 10.5 mm in caudal filament length. Its overall coloration is a consistent dark brown. The head lacks prominent tubercles but displays an irregular and spiculate vertex. Antennae are brown, darker towards the base. The head is dark brown with even darker vermiculate markings on the vertex, and the frons features a pair of dark brown submedian dashes and dots. The clypeus and labrum are dark brown, with shading extending along the ventral part of the genae. The thorax lacks tubercles and exhibits a rather uniform dark brown coloration, slightly darker along the lateral margins. The thoracic sternum is uniformly brown. Femora are light brown to brown with numerous spines, while forefemora bear a narrow subapical band of spines. Tibiae and tarsi are uniform light brown, unbanded, with some specimens having slightly darker tarsi. Tarsal claws have 7-9 denticles, darker at the apex. Abdominal terga feature small, acute, paired submedian tubercles on segments 3-8, sometimes also on segments 2 and 9. Terga are mostly uniform dark brown, occasionally darker on segments 5-10, lightly spiculated, with distinct posterolateral projections on segments 4-9. Civate W is weakly produced or absent on segment 3. Abdominal sterna are brown, with sterna 2-8 typically bearing paired sublateral dark brown maculae and dark brown anteromedian spots and oblique dashes. The caudal filaments are dark brown at the base and light brown apically, with whorls of spines at the apex of each segment along the entire length of the filaments, and long, sparse inter-segmental setae
