): Abdomen near half the length of the body, each segment with dark lateral marks and extended posterolateral margins. Sternum 9 slightly extended backwards, posteromedially with a small, slightly elevated transverse lobe. Tergum 10 sclerotized and seems cleft, without projected hemiterga. Paraproct broad, sclerotized, almost flat, subtriangular from ventral aspect; lateral margins slightly thickened and up-folded; apex slightly elevated, more sclerotized and blunt. Abdominal tip with an obscure, posteromedial subuliform structure between and beyond paraprocts. Cerci hairy and short gradually elongated and narrowed from base to apex, with 10 to 11 segments and each segment with clustered long setae.

Holotype male, NIGP167159. Pro- and meta-nota are not preserved in this specimen. Wings are overlapped so it’s hard to see the details of the basal part of the wings. Dorsal abdomen is covered by unknown, obscuring substance, so the detailed structure of tergum 10 is not visible.
