Antenna 5-segmented. Premandible trifid, first and third longer and pointy, middle tooth shorter and broader. Mandible very slender with 2 dorsal and 5 inner teeth; all teeth pale. Mentum arched, weakly pigmented with four median teeth and 6 pairs of lateral teeth; outer pair of median teeth very small, first lateral tooth broad and the other laterals decreasing in size. Ventromental plates broad and largely arched, anterior margin finely crenulated. Remarks: Pagastiella differs from Nilothauma by having unusual position of setae submenti on the ventromental plates ( Fig. 87 ) and very small outer pair of median teeth, while in Nilothauma the central pair of median teeth is narrower. The only Palaearctic species, P . orophila (Edwards, 1929) , is also known from the Tatra Mts. lakes. Subfossil remains were found rarely and in low abundances in lakes of the forest zone.
