Abstract

Here we report the first record of Lasiodimesa (Podonominae) in Slovakia. A single larva was collected in a small and shallow alpine pond located at 1,654 m a.s.l. in the High Tatra Mountains. Acidotolerant taxa such as Psectrocladius octomaculatus, Zalutschia tatrica, Synendotendipes sp. and Tanytarsus cf. gregarious were present in the community of the pond. Our finding indicates that the typical habitat of Lasiodiamesa larva is not necessarily a bog, but can also be a small acidic waterbody.

Highlights

  • A combination of drift sampling and the kicking technique was used to collect larvae and pupal exuviae

  • The material is deposited at the Department of Biology and General Ecology, Technical University in Zvolen, Slovakia

  • One species is known from Scandinavia (L. armata Brundin 1966) and one from Germany and Norway (L. bipectinata Sæther 1967)

Summary

Introduction

A combination of drift sampling and the kicking technique was used to collect larvae and pupal exuviae. Preimaginal stages of chironomids were picked, mounted on permanent slides and identified using Sæther and Andersen (2013). For the list of other invertebrates recorded in the pond see Table 2.
