Key: Step 456. Tanytarsini 97 Tanytarsus

456a. Frontal setae very thin, less than 60µm long. Comb of segment VIII small, about 20µm across, with 3-5 marginal teeth. (Despite the very small size of this exuviae (2.9-3.0mm, anal lobe length 133-145µm), the fringe taenia number (13-27) and hook number of hook row II (62-77) are similar to those of related, larger species.)

Tanytarsus lactescens

456b. Frontal setae more robust, over 90µm long. Comb of segment VIII broader and bearing more marginal teeth.
