Remarks. In Schizotrema, the carapace is high as in Nannastacus, higher than in Cumella; the eyes are always as in Nannastacus, but the pseudorostral lobes are completely separated from base to top, not like in Nannastacus, Scherocumella or Cumella. The uropodal peduncle is as long as or shorter than pleonite 6, as in Nannastacus.
