The Family

The family Encyrtidae is represented by two subfamilies, Encyrtinae and Tetracneminae, and currently includes over 460 genera and nearly 3,800 described species (Noyes, 2003). All Tetracneminae and the majority of Encyrtinae are reported as parasitoids of mealybugs, whereas some encyrtines are associated with a number of other arthropod hosts (Noyes, 2003; Simutnik & Trjapitzin, 2008).

Plesiomorphic Character

Succinoraphidia radioni sp. nov. (Raphidiidae) is described from the late Eocene Rovno amber, Ukraine. The genus also includes two species from contemporaneous Baltic amber, i.e., S. exhibens Aspöck & Aspöck, 2004 and S. baltica (Carpenter, 1957), comb. nov. The venation of Succinoraphidia is analysed. It possesses several plesiomorphic character states at the family level, and the monotypic subfamily Succinoraphidinae represents a basal group within the family or possibly even a potential stem group of Raphidiidae. All diagnostic character states of Succinoraphidia (except the structure of the pterostigma) are found in a few Cretaceous species of the paraphyletic Mesoraphidiidae, but some of these are not found in the extant Raphidiidae.

The first fossil representative of the family Barbutiidae is recorded from late Eocene Rovno amber. Barbutia theroni sp. nov. is described based on deutonymph female. An updated key to deutonymph females of Barbutia is provided. For recently described fossil species Hoplocheylus similis Khaustov, Vorontsov, Perkovsky & Lindquist, 2021 a replacement name H. neosimilis nom. nov. is proposed.

A New Species

A new species of malachite beetles, Protomauroania mikhailovi Tshernyshev & Perkovsky, sp. n. is described from late Eocene Rovno amber. The new beetle is the second species of the Eocene fossil genus Protomauroania Tshernyshev, 2021 that was first recorded in Rovno amber and shows fauna similarity of dasytids in Baltic and Rovno amber. The new species is typical owing to the following characters: antennae with 5-segmented wide club, surface covered with dark-brown long semi-erect thin setae, and the ultimate ventrite (apical sternite) simple, narrow, not depressed. Digital high resolution pictures of the beetle are provided.

Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

The First Eocene Species of the GenusCryptophagus(Coleoptera, Clavicornia, Cryptophagidae)Based on a fossil specimen from the Late Eocene Rovno amber (Ukraine),Cryptophagus harenusLyubarsky et Perkovsky, sp. n., an Eocene species of this genus is described. The new species is similar to the extant desert speciesCryptophagus desertusLyubarsky andC. recticollisSolsky, differing by the large callosity occupying 1/4 length of lateral margin of pronotum.
