Abstract

Three microphthalmous and presumably locally endemic species of Tychobythinus Ganglbauer, 1896, a pselaphine genus previously unknown from Georgia, are described and illustrated: T. meskheticus spec. nov. (Southwest Georgia: Meskheti Range), T. eximius spec. nov. (Northwest Georgia: Egrisi Range), and T. egrisicus spec. nov. (Northwest Georgia: Egrisi Range). Tychobythinus eximius is particularly remarkable in that it is subject to a unique sexual dimorphism of the antennae and the pronotum. Including the new species, Tychobythinus is now represented in the Palaearctic region by 95 named species and two subspecies.<br>
