“…Based on the ant species composition, Rovno amber has been dated to the Upper Eocene (ca 36 Ma) (Dlussky & Rasnitsyn, ). Recent work on Tanytarsini midges (Chironomidae, Chironominae) suggests a very close deposition time between the ambers of Rovno and those of the Gulf of Gdańsk, as several species are common to both deposits (Giłka et al , ; Zakrzewska & Giłka, , ).…”

Species in the genus Corethrella Coquillett, the only genus in the family Corethrellidae, feed on the blood of frogs and toads and are unique among Diptera in locating their hosts by sound. Their fossil record goes back to the Cretaceous and comprises seven previously described species from various amber deposits. Herein, we present the first records of Corethrella from Late Eocene Rovno amber (35 Ma), with the description of two new species: Corethrella sontagae sp.n. based on a single male, and Corethrella rovnoensis sp.n. based on a single female. A revised key to fossil species of Corethrella is given. Phylogenetic relationships within Corethrella are investigated based on Bayesian and parsimony analysis, including the new data. All species groups recognized by Borkent (2008) are recovered as monophyletic, with the exception of the drakensbergensis group, which is found to be a paraphyletic grade. Both of the newly described species can be accommodated within modern species groups: C. sontagae shows affinities with the quadrivittata group and C. rovnoensis with the rotunda group.

“…The fossil chironomid fauna found in amber from the Baltic region is the best studied one, including the so far oldest known members of the Tanytarsini -the tribe within the second largest subfamily Chironominae (Seredszus and Wichard, 2007;Giłka, 2010Giłka, , 2011aGiłka et al, 2013;Zakrzewska and Giłka, 2013, 2015b. According to the current division, the oldest Eocene Tanytarsini are represented by genera classified in two known subtribes: Tanytarsina (see couplets 10-17 in a key given below) and Zavreliina (couplets [18][19][20][21], with the exception of the extinct genera with unexplained subtribal position (couplets 3-9) (Zakrzewska and Giłka, 2014Giłka, , 2015b. Evolutionary trends based on the fossils record of Eocene Tanytarsini were recently discussed by Zakrzewska and Giłka (2014, 2015b, whereas the higher level internal relationships within the Chironomidae, including the Chironominae and Tanytarsini, and their dating based on molecular analyses were presented by Cranston et al (2012).…”

This work is a systematic study of non-biting midges (Chironomidae) of the tribe Tanytarsini found in Baltic amber (Gulf of Gdańsk, ~40-45 Ma) collected by C. and H.W. Hoffeins, Hamburg, Germany. Given the rarity of Tanytarsini species/specimens so far recorded in Eocene ambers of the Baltic region, known from 17 species in eight genera, the Hoffeins collection is distinguished by its relatively high diversity. Among chironomid specimens collected, 39 Tanytarsini adult males were found, including 28 individuals studied in detail. They belong to 12 species from seven genera, including three new species. Rheotanytarsus hoffeinsorum sp. nov. is the second known Eocene species of the genus. Tanytarsus crocota sp. nov. and Stempellinella fibra sp. nov. display sets of unique characters in these genera. Emended diagnoses of Archistempellina falcifera Giłka and Zakrzewska, 2013 and A. perkovskyi Giłka and Zakrzewska, 2014, hitherto known from single individuals, and morphological variability in selected Eocene species of the genus Tanytarsus van der Wulp, 1874, are also presented. As a synthesis of our work and comparisons achieved in order to define the taxa studied, a key to the identification of all Eocene Tanytarsini genera (8) and species (20) known from Baltic amber is provided.

Cladotanytarsus (Cladotanytarsus) crassus sp. n. is described from the USA (Oregon, Wyoming) and Canada (Ontario). The distinctive structure of the adult male hypopygium, bearing a thickset digitus and a stout elongated superior volsella, is presented. Intraspecific morphological variations are described in order to compare C. crassus and C. nigrovittatus (Goetghebuer, 1922), treated as close relatives. The geographical distribution and ecology of the two species are commented on.
