The upper surface of the abdomen has club hairs and lacks tiny spines and scale hairs. The prosternum exhibits substantial sclerites within the intersegmental fold, and the submentum has an apical notch. Head: The head is approximately square in shape. The lateral sides of the frontoclypeal apotome narrow at the anterior fifth. The anterior margin of the frontoclypeal apotome is complete, straight, and crenulated, featuring a series of round flanges. Each anterolateral corner of the frontoclypeus has a straight diagonal ridge extending from the constricted point of the frontoclypeal suture to the lateral fourth of the front margin of the frontoclypeus. The regions of the frontoclypeus anterolateral to the diagonal ridges are bent ventrad. The posterior angle of the mediotransversal fold is round and wide, with the tentorial pit situated at the anterior three-tenths of each arm of the fold. The region bordered by the mediotransversal fold and anterior diagonal ridges is distinctly depressed and flattened. Thorax: The thoracic setation is similar to that of the head, with thoracic nota densely covered with short, fine, tapered, dark hair-like setae. There are scattered short, thick, golden, transparent peg-like setae, and their setal sockets are light-colored. Both primary setae and peg-like secondary setae are inconspicuous in dorsal aspect, providing the thoracic nota with a somewhat shiny appearance under microscope illumination. Abdomen: Abdominal segments appear whitish in preserved specimens, and scale hairs are sparse. Abdominal pleura on segments III to VI each bear one simple, conical lateral gill on the posterior region, pointing posterad. Abdominal segments I and VII each have one ventrolateral gill on each side, which is bifid-stemmed. Segments II to VI each have one bifid-stemmed ventrolateral gill and one single-stemmed ventromesal gill on each side. Single-stemmed gills are situated anteromesad to bifid-stemmed gills on each segment when both are present.
