Material examined. Six female paratypes, USA, leaf trash, Sanburn, Johnson County, 111, 20 September 1949, Coll. P.W. Smith and L.J. Stannard.

Remarks. Most of the studied paratypes are in bad condition and this redescription is based on a less damaged specimen.

Delfinado and Baker (1974) synonymized the genus Neotydeus to Scolotydaeus but it was later revived by Seeman and Walter (1999), pending more comprehensive study. In my opinion Neotydeus considerably differs from Scolotydaeus by the absence of eyes, presence of only two pairs of genital acetabulae and non-bifurcate unguinal setae on tarsi II–IV.
