ABSTRACT: Two new species of the genus Neottialges Fain, 1966 are described from nests of herons and gull-like birds from the northern coastal region of the Black Sea (Ukraine): Neottialges (Ardeidectes) sevastyanovi sp. n. from Larus genei Brème, 1839 (Charadriiformes: Laridae) and N. (Heronidectes) gracilipes sp. n. from Nycticorax nycticorax (Linnaeus, 1758) (Ciconiiformes: Ardeidae). Adults of the Hypodectes nycticoracis Filippi, 1861, the type species of the genus Hypodectes Filippi, 1861, are described from its type host, N. nycticorax, for the first time. Brief comments on systematics on the genera Hypodectes and Neottialges Fain, 1966 are provided. Based on differences in leg and palpal chaetotaxy between adults in the subgenera Hypodectes and Hypodectoides Fain and Bafort, 1966, we elevate the latter subgenus to the generic rank.

KEY WORDS: Hypoderatidae, Hypodectes, Neottialges, systematics, new species.
