Aquanirmus colymbinus (Scopoli, 1763)

Host: Podiceps auritus (Linnaeus, 1758) .

Ref.: Balát (1953, 1956, 1977).

Location: Pezinok, Nov.–Dec. 1948 (Balát Coll., MMBC slide number 348) .

Notes: There are only two nymphs on a slide in the Balát Collection, which are not suitable for a species identification. Therefore, considering that Podiceps auritus is the type host of Aquanirmus colymbinus, we accept Balát’s identification as reported in his papers.
