Upper Paleozoic

In the Lower Devonian the first productellids evolved from their chonetidine ancestors as the Productellinae. This subfamily was the stem group from which all the later Productidina evolved, yet three of its five subfamilies persisted to the end of the Permian. The main characters used in the new classification, here presented, for the Productellidae are described and reviewed, and the main changes seen during its evolution are discussed. Within this new classification five new genera are described: in the Overtoniinae are Barunkhuraya Lazarev from the latest Famennian, Onavia Lazarev from the Tournaisian, both from Mongolia, and Echinariella Lazarev (type species Krotovia jisuensiformis Sarycheva) from the late Permian of Transcaucasia; in the Marginiferinae there is Breileenia Brunton from the Visean of western Europe and in the Plicatiferinae is Maemia Lazarev from the mid and Upper Carboniferous on the coast of the Barents Sea. New species described in these genera are Barunkhuraya indrengynensis Lazarev, Onavia barunkhurensis Lazarev, Breileenia radiata Brunton, Maemia chaykensis Lazarev, and M. nana Lazarev.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Stratigraphic Ranges

Platycrinitesis traditionally one of the more recognizable crinoids, a camerate crinoid with very few if any fixed brachials or interradials and a helically twisted column. Accordingly, many taxa have been assigned to this genus. With a better understanding of the Platycrinitidae, these characters actually unite the family Platycrinitidae rather than the genus. Further, use of different genus-diagnostic characters in Western Europe versus North America has resulted in a confused systematics for this important late Paleozoic family. Here, we objectively define genera within the Platycrinitidae and assign all species to either newly defined or newly named genera. A phylogenetic hypothesis, incorporating both parsimony-based character analysis and stratigraphic ranges, of the genera within the Platycrinitidae is presented.With consideration of the type species,Platycrinites laevisMiller, 1821,Platycrinitessensu stricto is distinguished fromPlatycrinitessensu lato, which is used for species that cannot be assigned with confidence to any objectively defined genus. New genera areArtaocrinusn. gen.,Collicrinusn. gen.,Elegantocrinusn. gen., andLaticrinusn. gen.; andExsulacrinusBowsher and Strimple, 1986 is designated a junior synonym ofPlatycrinitess.s.Collicrinus shumardin. gen. and sp.,Laticrinus owenin. gen. and sp., andLaticrinus wachsmuthin. gen. and sp. are described; andPlatycrinites formosus approximatus(Miller and Gurley, 1896a) is designated a junior synonym ofPlatycrinites formosus(Miller and Gurley, 1895a), which is reassigned here toCollicrinusn. gen.Platycrinitess.s. now includes 14 species and species-level taxa, and 76 species are assigned toPlatycrinitess.l. Ten species are designated nomina dubia, as are taxa based solely on columnals or pluricolumnals. Two species are designated nomina nuda, and two are transferred to genera outside of the Platycrinitidae. In addition, twenty-seven species and four open-nomenclature taxa are each reassigned to a different genus.

Two species are removed from the genus Poa in Australia on the basis of morphology and DNA and placed in new genera. One is placed in Saxipoa Soreng, L.J.Gillespie & S.W.L.Jacobs – type: S. saxicola (R.Br.) Soreng, L.J.Gillespie & S.W.L.Jacobs; and one is placed in Sylvipoa Soreng, L.J.Gillespie & S.W.L.Jacobs – type: S. queenslandica (C.E.Hubb.) Soreng, L.J.Gillespie & S.W.L.Jacobs. An infrageneric classification of Poa is proposed that places all 41 indigenous Australian species in P. subg. Poa supersect. Homalopoa sect. Brizoides. Thirty-three of these species, plus six species of New Zealand Poa, are placed in a new P. subsect. Australopoa Soreng, L.J.Gillespie & S.W.L.Jacobs. Two species are placed in P. subsect. Austrofestuca (Tzvelev) Soreng, L.J.Gillespie & S.W.L.Jacobs, one in P. subsect. Brizoides (Pilg. ex Potztal) Soreng, L.J.Gillespie & S.W.L.Jacobs, and one in P. subsect. Neuropoa (Clayton) Soreng, L.J.Gillespie & S.W.L.Jacobs.

The pygmy grasshopper subfamily Batrachideinae consists of three tribes: Batrachideini Bolívar, 1887; Cassitettigini Yin, 1984, nom. resurr.; Bufonidini Hancock, 1907, nom. resurr., stat. nov. The Australian pygmy grasshoppers of the tribe Bufonidini are reviewed. Three new genera are described, namely Paraselina gen. nov. (type species Vingselina multifora Rehn, 1952), Anaselina gen. nov. (type species Vingselina minor Sjöstedt, 1921), and Selivinga gen. nov. (type species Selivinga tribulata sp. nov.). Four new combinations are proposed: Paraselina multifora (Rehn, 1952), comb. nov.; P. trituberculata (Sjöstedt, 1932), comb. nov.; P. brunneri (Bolívar, 1887), comb. nov.; Anaselina minor (Sjöstedt, 1921), comb. nov. A key to Australian genera of Batrachideinae is provided.

Stratigraphy and palynology of the Lower Carboniferous Sortebakker Formation, Wandel Sea Basin, eastern North Greenland. Geology of Greenland Survey Bulletin, 187, 51-63. https://doi.org/10.34194/ggub.v187.5194 _______________ Two palynological assemblages of Early Carboniferous age have been recorded from the upper parts of the non-marine, fluvial-dominated Sortebakker Formation in the Wandel Sea Basin. The stratigraphically lower assemblage includes poorly preserved Cingulizonates spp., Densosporites spp., Lycospora spp. and Schulzospora spp. whereas the upper assemblage contains a more diversified microflora including the stratigraphically important Tripartites distinctus, Potoniespores delicatus and Savitrisporites spp. The microflora enables correlation and dating of the succession to the late Viséan Perotrilites tessellatus – Schulzospora campyloptera (TC) and Raistrickia nigra – Triquitrites marginatus (NM) miospore Biozones of western Europe. The depositional facies correspond to those seen in time equivalent deposits from East Greenland, Svalbard, Bjørnøya and the Barents Sea.

AbstractCryptovelia terrestris n. gen., n. sp. (Brazil), Darwinivelia fosteri n. gen., n. sp. (Galapagos Is.), Mniovelia kuscheli n. gen., n. sp. (New Zealand), and Cavaticovelia n. gen. (type-species: Speovelia aaa Gagné & Howarth, 1975; Hawaii) are described. The phylogenetic relationships between the mesoveliid genera are discussed in the light of characters revealed by the new taxa. Habitat preferences of mesoveliids include humid terrestrial and/or marginal aquatic habitats, which probably are the most ancestral, and lava-tubes, coastal caves, intertidal marine habitats, and the plant-covered freshwater surface, which probably are the derived kinds of habitats. A classification of the Mesoveliidae with a check list of genera and species is presented. Two subfamilies are recognized: Madeoveliinae (with two genera) and Mesoveliinae (seven genera). The biogeography of the Mesoveliidae is finally discussed.

Ethiopian Region

While the Oriental and Neotropical Trypaneids have been the subject in recent times of extensive studies, those of the Ethiopian Region are still almost in the same condition in which they were left by H. Loew in his valuable paper of 1861. Only more recently Prof. Hendel has made an attempt to erect some Ethiopian genera in his general classification of the family; but all these genera are only shortly characterised by means of dichotomic tables, and most of their type-species have been given names as new species, but without any description.
