C175F4125F78FF81FF33FF1FFBDCFDB6.taxon	discussion	Remarks. Pseudoaerumnosa regularis sp. n. is similar to P. annae in having an elongate gonostylus and the tegmen straight laterally, but differs in having a narrow aedeagus and 3 megasetae on the lobe of gonostylus, while having a broad aedeagus and 4 megasetae on the lobe of gonostylus in P. annae. Etymology. The species is named after its regularly-shaped hypopygium, from the Latin, regularis, meaning regularity.	en	Chen, Zuluan, Yang, Xue, Menzel, Frank, Wu, Hong, Huang, Junhao (2021): Three Oriental species of Pseudoaerumnosa Rudzinski (Diptera, Sciaridae) from China.
