Description
Geocenamus tartuensis (Krall, 1959) Brzeski, 1991
(Table 5; Fig. 4, 5 P–T, 6 K– O, 8 A–D)
Two populations of this species were identified (see Table 5). This species comes close to G. paniculoides and G. siddiqii in having refractive basal extensions of the cephalic framework (see G. paniculoides for differences).
