A New Species

A new species of inocelliid snake-fly,Fibla carpenteri, is described and figured frorn Middle to Upper Eocene Baltic amber. The species belongs to the nominate subgenus and is the largest amber snake-fly currently known. The aberrant fossil speciesInocellia peculiarisis transferred to a new genus,EIectrinocellia, and placed in a new subfamily, the Electrinocelliinae, sister to the remainder of the Inocelliidae.

A New Species

Lonchodryinus groehni sp. nov. (Hymenoptera: Chrysidoidea: Dryinidae) is described from Baltic amber. The new species is close to L. balticus Olmi & Guglielmino, 2012, but it can be distinguished for the different OPL/POL ratio and 2r-rs&Rs vein of the fore wing. A key to the fossil species of Lonchodryinus and a comparison with the extant species L. ruficornis (Dalman, 1818) are presented.

A New Species

A new species of the extinct scydmaenine genus Euroleptochromus Jałoszyński (Mastigitae: Leptochromini), E. tuberculatus Yin & Cai, sp. nov., is described from Eocene Baltic amber. It can be separated from the two previously known congeners by the different proportions of the body parts and spination of the profemur, and more importantly, lack of an elongate postgenal process of the head. Our finding demonstrates for the first time a notable variability of the postgenal structures within Euroleptochromus.

A New Species

A new species of pincer wasps, Bocchus schmalhauseni sp. nov. (Dryinidae) is described from Rovno amber (Ukraine). The amber piece was collected in the Vladimirets District in the north-west of the Rovno region. Taking into account this new record, a total of five species of Dryinidae are registered from Rovno amber. A key to the fossil species of Bocchus Ashmead is presented. The possible reasons for the different distribution of Dryinus species on both coasts of Subparathetys are discussed.

AbstractFossil species of Pristaulacus are uncommon, with just two known species, P. mandibularis Brues and P. praevolans Brues from Baltic amber, and three species, P. bradleyi (Brues), P. rohweri Brues and P. secundus (Cockerell), from the Florissant fossil beds, Colorado, USA. Here we provide a detailed description of Pristaulacus velteni sp.n., the third fossil species known from Baltic amber.

A New Species

Few species of Baltic amber Psychodinae have been described to date. Some were incorrectly classified in Pericoma Walker based on an early, broad definition of the genus and holotypes were not specified. We examined approximately 50 specimens of Baltic amber Psychodinae in addition to reviewing the original series studied by Fernand Meunier. Lectotypes for Pericoma formosa Meunier and P. speciosa Meunier are designated and Paleotelmatoscopus gen. nov. is proposed to include P. formosa and P. madrizi sp. nov. Characters included in the diagnosis of this new genus and species have implications for future descriptions of Baltic amber Psychodinae. Parts of the head capsule, such as antennae, are often well-preserved and visible, and can be useful for separating species. However, these character complexes are prone to homoplasy and should not be used alone to define genera. Since it is impossible to view internal genitalic characters in fossil species, refinement of generic and species diagnoses based on external morphology is a critical factor in describing the amber fauna.

A new species of comb-clawed beetles of the genus Asiomira Dubrovina, 1973 (A. dubrovinae sp. n.) is described from the Eocene Baltic amber. This newly descovered fossil species displays typical generic characters and is the most similar to the extant Asiomira ophtalmica (Seidlitz, 1896). Both species share a similar shape of the pronotum and the flattened posterior angles of the pronotal disc. Asiomira dubrovinae sp. n. can be distinguished from A. ophtalmica by the smaller body size (4.8 mm in contrast to 6–8.12 mm), more serrate antennomeres, and finer and sparser pronotal punctation. Extant species of the genus are distributed in the arid landscapes of Central Asia with the highest diversity occurring in Tajikistan. Therefore the discovery of a new fossil species from Eocene Baltic amber suggests that Asiomira could have a wider range, and the modern distribution of this group is the result of a later secondary expansion of the ancestral representatives that survived in mid-mountain areas with arboreal and shrub vegetation. Relevant corrections to the distribution of extant species, Asiomira ophtalmica (Seidlitz, 1896) and Asiomira firjusana (Dubrovina, 1973), are given.

A new genus and two new amber fossil species of Leiodidae are described: Catops perkovskyi sp. n. (CholevinaeCholevini) and Tafforeus cainosternus gen. n., sp. n. (Leiodinae Pseudoliodini); using virtual dissection by propagationphase contrast synchrotron X-ray microtomography, which allows for visualization of the genital structures in a non-invasive way. The external and internal morphology of the new species is compared to that of the extant related species.Putative evolutionary relationship between Tafforeus and the genus Cainosternum Notman, 1921, and their placement in the tribe Pseudoliodini are discussed.

A New Species

Examination of Baltic amber Plecoptera reveals a new species of Isoperla: Isoperla baltica sp. nov. The placement of this new species is supported by an in-depth comparison of apomorphies supporting families, subfamilies, and suborders. Contrary to previous descriptions of many fossil species, we took advantage of the good preservation of the genitalia to describe and compare this new species to its extant congeners. Finally, we discuss the usefulness and limitations of relying on wing venation to identify diagnostic characters in Plecoptera by figuring a specimen of Pteroliriope sinitshenkovae Cui, Béthoux, Kondratieff, Shih & Ren, 2016 with numerous crossveins and an original organization of forewing veins.
