Type species. Pseudolonchodina irregularis Zhou, Zhai, and Xian, 1981 .

Diagnosis. Apparatus is composed of Sa, Sb, Sc, M, Pa, and Pb elements. Pa and Pb elements have a central cusp with two lateral processes. Lateral processes twist at different angles away from the cusp, giving the elements a digyrate morphology. M elements are dolabrate with a basal cavity that extends the length of the process. Sa elements are alate with a basal cavity that extends posterior to the cusp. Sb elements are tertiopedate with a deep basal cavity beneath each process. Sc elements are bipennate. Denticles are long, thin, and laterally compressed.

Remarks. Aspelundia is a junior synonym of Pseudolonchodina . See Wang and Aldridge (2010) for discussion.
