(2007) . Head capsule dark brown. Mentum with two median teeth and 5 pairs of equidistant lateral teeth. Brooks et al . (2007) present only one Eukiefferiella morphotype with double median tooth, E. claripennis - type , which differs in some minor but obvious features from the type found in the Tatra Mts. In our case the median teeth are well-sepa rated and broader then the first lateral teeth that are clearly separated from the median teeth with a deep notch; in Brooks et al . (2007) , median teeth are narrow and weakly separated, and first lateral teeth are appressed to medians. The former reminds E. rectangularis group, recently placed to Tokunagaia rectangularis group. We assume that our morphotype represents this taxon occurring in cold springs ( Bitušík 2000 ) and lakes ( Hamerlík et al . 2017 ) in the High Tatra Mts. and sediment cores from the high alpine Nižné Terianske pleso lake ( Bitušík & Kubovčík 1999 ). To distinguish the two morphotypes, we named the one recorded in the Tatra Mts. lakes E. claripennis - type B.
