Phaenopsectra flavipes (Meigen, 1818)

Diptera : Chironomidae : Chironominae: Chironomini:

Material examined: a pond close to Moškovec village ( Fig. 1a ), C Slovakia, 48.9492222 N, 18.8475556 E, 440 m a. s. l., 1 pupal exuvia, 29. 8. 2013, leg. L. Hamerlík, det. et coll. V. Štillová. Larvae of Phaenopsectra most likely belonging to the same species were collected from two other sites: a pond near Holiša ( Fig. 1b ), C Slovakia, 48.3068611 N, 19.7512222 E, 175 m a. s. l., 10. 7. 2013 (1 larva), and a pond next to Stráňany ( Fig. 1c ), E Slovakia, 48.3430667 N, 20.5265528 E, 824 m a. s. l., 16. 7. 2013 (2 larvae) .

The material was collected using a combination of drift sampling (to obtain pupal exuviae) and the PLOCH method ( Oertli et al. 2005) to collect larvae. Preimaginal stages were picked, mounted as permanent slides and identified using keys by Langton and Visser (2003) and Wiederholm (1983). The material is deposited at the Department of Biology and Ecology, Matej Bel University, Banská Bystrica, Slovakia.

In our study, all three sampling sites (ponds) with the occurrence of Phaenopsectra harboured fish and macrophytes with Berula erecta , Equisetum fluviatile , Eriophorum angustifolium , and Potamogeton berchtoldii being the most dominant ( R. Hrivnák, pers. comm). Fine sediment constituted the bottom of ponds near Holiša and Stráňany, while the bottom of the Moškovec pond was more heterogeneous, consisting of coarse mineral substrate, gravel and fine sediment (50%, 30%, and 20%, respectively). The catchment area of the Moškovec pond was dominated primarily by grassland, while that of Stráňany and Holiša were dominated by forested and urbanized land, respectively. Other specific hydromorphological and physio-chemical data for each pond can be found in Table 1 .
