Dactylolabis ( Eobothrophorus ) lauryni

A new species of Dactylolabis ( Eobothrophorus ) from Baltic amber (Diptera: Limoniidae) .... pdf.

Abstract. A new species – Dactylolabis (Idiolabis) ryszardi n. sp. from Eocene Baltic amber is described. It is the third species of this extinct subgenus to be described and is known exclusively from Eocene Baltic amber. The distinctive fea tures of the newly described species are the character of wing venation, especiall y the shape of discal cell, characteristically indented in upper distal corner by the position of dM 1+2 shifted to 1/3 of d-cell, and the morphology of the hypopygium. A parsimon y analysis of type species of extant taxa and extinct species of the genus Dactylolabis from Baltic amber is provided based on 25 morphological characters. The analysis con firms the status of extinct subgenera from the Eocene Baltic amber currently recognized within the genus Dactylolabis and shows the modern and fossil taxa grouped separately .

Dicranomyia gorskii

A new species Dicranomyia Stephens, 1829 from Baltic amber (Diptera: Limoniidae, .... pdf.

Abstract.— A new species of the genus Dicranomyia Stephens, 1829 (Diptera: Limoniidae) from Baltic amber (Eocene) is described. The characteristic feature distinguishing a new species, D. gorskii sp. nov. is the presence of the surprisingly strong and elongate spine on rostral prolongation of ventral gonostylus. The morphological features of the new species are briefly discussed. New replacement name Dicranomyia alexandri nom. nov. for Dicranomyia flagellata (Alexander, 1931) is proposed to avoid with Dicranomyia flagellata Edwards, 1928.

Winnicavis gorskii gen. et sp. nov.

Articulated avian remains from the early Oligocene of Poland adds to our understanding of Passerine evolution .... pdf.

Abstract—In total, less than 50 specimens of the Passeriformes are known from the Paleogene, which contrasts with the fact that now it is the largest and most diverse order of birds. The so far described fossils include only three nearly complete specimens, an articulated wing and legs, and a handful of isolated bones. This paper describes a new species and genus of a passerine bird the size of the extant Parus major, imprinted on a slab and a counter slab of the siliceous clayey shales of the Outer Carpathians in southeastern Poland, and dated to the Rupelian, early Oligocene (ca. 31 m.y.a.). It is one of the very few passerine specimens from the Paleogene with bones in articulation, and thus provides a window into the ancestral osteology of passeriforms, which is characterized by a mosaic of characters typical for extant Oscines and Suboscines. The bird shows a unique manus, with a relatively short carpometacarpus and cleavershaped phalanx proximalis digiti majoris. Besides bones, fragmentary feathers are also imprinted on both slabs.

Electribius gorskii sp. nov.

Key to species of Caulophilus known from Eocene amber is given.

Omaliella polonica sp. nov .. .... pdf.

Abstract: Archaeorthoptera is a high rank insect taxon comprising Orthoptera as well as the extinct orders Titanoptera and Caloneurodea, and several other late Paleozoic groups formerly assigned to polyphyletic Protorthoptera. Synapomorphies defining Archaeorthoptera and some fossil subordinate taxa are exclusively based on wing venation. This study presents a detailed description of two new archaeorthopteran genera and three new species from the Pennsylvanian of the Upper Silesian Coal Basin in Poland.

Bacanius gorskii sp. nov.

A new Eocene Bacanius species (Histeridae: Dendrophilinae)from Baltic amber .... pdf.

Abstract: A study of Baltic amber revealed a new fossil species of the genus Bacanius LeConte, 1853. Bacanius gorskii sp. nov. differs from the congener described previously from Eocene Rovno amber, B. kirejtshuki Sokolov and Perkovsky, in the shape of meso-metaventral suture, incomplete subhumeral stria, and the impunctate prosternal lobe (urn:lsid:zoobank.org:pub:EE9C6859-607A-4134- 9037-8385601CF42F). 1 Introduction The clown beetle family (Histeridae) is nearly cosmopolitan in distribution, and it is very diverse both ecologically and morphologically (Caterino and Vogler, 2002). Histerid beetles comprise over 4000 extant species. Ten subfamilies are presently recognized (Zhou et al., 2020): Antigracilinae, an extinct subfamily from the Lower Cretaceous, and the extant subfamilies Niponiinae, Abraeinae, Saprininae, Dendrophilinae, Onthophilinae, Tribalinae, Histerinae, Haeteriinae, and Chlamydopsinae. Histerid beetles, although generalist predators, have widely varied habitats and are associated with different substrates including dung, carrion, fungi, dead and dying trees, leaf litter or other decomposing vegetation, and symbioses with other animals, most spectacularly with social insects (Caterino and Vogler, 2002). Various histerid genera belonging to subfamilies Abraeinae, Histerinae, and Dendrophilinae have been listed from Baltic amber inclusions (Klebs, 1910; Larsson, 1978; Spahr, 1981), but only two representatives of the tribe Paromalini have been formally described hitherto (Alekseev, 2016). Recently, one fossil species of Bacanius, B. kirejtshuki, has been described from Eocene Rovno amber (Sokolov and Perkovsky, 2020). In this study, description of a new species, Bacanius gorskii sp. nov., an extinct Eocene representative of the tribe Bacaniini, is presented.
