Type species of the genus is Petalophthalmus inermis Willemoes-Suhm, 1874. The name comes from the neo- (Greek new) and Birsteiniamysis (the unavailable genus-name, replaced by Neobirsteiniamysis). ^{[1] [4]}

Classification

Includes 2 species:

• Neobirsteiniamysis inermis (Willemoes-Suhm, 1874)
• Neobirsteiniamysis caeca (Birstein et Tchindonova, 1958)
