Key to genera of Diploscapteridae (from Andrassy, 2005).

1. Each labial hook with a short spine close to mouth opening; stoma cylinder width about 30% of body diameter at the same level        Carinoscapter Siddiqi, 1998
2. Labial hooks without spines.  Stoma cylinder 20-25% as wide as corresponding body diameter                                                         Diploscapter Cobb, 1913
