The plesiomorphon Palaeoblattariae Scudder 1879 includes extinct taxa only whose long, functional ovipositor separate them from the Oothecophora (and Cryptovipositoria in general). Originally, Scudder (1879) included in the Palaeoblattariae the extinct forms placed in genera Mylacris Scudder 1868, Archimylacris Scudder 1868, and the newly described genera Lithomylacris, Necymylacris, Etoblattina, Anthracoblattina, Gerablattina, Hermatoblattina, Progonoblattina, Oryctoblattina, and Petrablattina. The Neoblattariae Scudder 1895 originally encompassed all Recent cockroaches plus the extinct Mesozoic genera Neorthroblattina Scudder 1885 and Scutinoblattina Scudder 1885, and originally excluded, besides the palaeoblattarian taxa listed above, the extinct forms arranged in genera Paromylacris Scudder 1885, Microblattina Scudder 1895, Spiloblattina Scudder 1884, Poroblattina Scudder 1885, and Leptoblattina Woodward 1887, all placed by Scudder (1895) with the Palaeoblattariae. All these extinct forms were originally described based on wing venation only; palaeoblattarian specimens with ovipositors were discovered later, but for most species Scudder originally included in the Palaeoblattariae there is still no evidence of ovipositor or lack thereof.

The name Palaeoblattida Brongniart 1893 was introduced as emendation of Palaeoblattariae Scudder 1879 and originally applied to a family consisting of the same set of taxa as Scudder’s Palaeoblattariae, to which Brongniart added a number of new species. He also provided drawings of the Anthracoblattina ensifer and Etoblattina sp. females with long ovipositors (Brongniart 1893: Pl.XLIII (32): Fig. 2–4).

To avoid creating new names, I suggest to accept the original circumscriptions of both Palaeoblattariae Scudder 1897 and Palaeoblattida Brongniart 1893 as fitting the plesiomorphon excluding Cryptovipositoria, and the original circumscription of Neoblattariae Scudder 1895 as fitting a taxon within Cryptovipositoria-Oothecophora, until proven otherwise.
