A New Species

A new species of the family Grammolingiidae (Neuroptera) (Leptolingia imminuta sp. nov.) is described from Daohugou village (Middle Jurassic), Inner Mongolia, China. In this new species, MA forks at the same level as the separation of Rs2 from Rs, close to the middle of forewing, this structure of MA is peculiar in Grammolingiidae and is different from that of all other known species. Moreover, this new species is the smallest species known in the family Grammolingiidae (30 mm wing span).

Ocala Limestone

Oyenaster oblidus, Ocalaster timucum, and Ocalaster seloyi are new genera and species of the family Goniasteridae (Asteroidea) described from the Eocene Ocala Limestone of Florida. Although the fossil record of asteroids is sketchy, goniasterids appear to have been important contributors to marine communities since at least the Middle Jurassic. Similarities between living goniasterids and their fossil precursors indicate that plesiomorphy and convergence have been important in family history, and as a result, taxonomic interpretation is challenging. Even partial fossil goniasterids are rare, forcing systematists to rely heavily on isolated marginal ossicles, although some authors have expressed the need for caution. Building around three new taxa, we suggest that broader approaches can aid systematic interpretation of all crown-group asteroids. We also suggest that the inevitably idiosyncratic interpretations of marginal-based systematics can be partially tested using blind evaluations.

Evolutionary Point

The following observations are the result of working over the Middle Jurassic Arcidae with a view to monographic treatment of the Corallian and Bathonian species. The monographs must of necessity be slow in appearing, and in any case they are not the place to discuss the broader conclusions to which the investigations have led. The family is one full of interest from an evolutionary point of view, but an exceptionally involved maze of controversial matter, chiefly concerning nomenclature, by which the Arcidae have been burdened, has obscured the features of interest and the phylogeny.

Taxonomic Keys

Two new species,Symphytopterus gracilersp. nov. of the family Ephialtitidae andPraeaulacus byssinussp. nov. of the family Praeaulacidae, are described and illustrated from the late Middle Jurassic of Jiulongshan Formation at Daohugou in Inner Mongolia, China. Based on new information onS. gracilersp. nov. andP. byssinussp. nov., two taxonomic keys to the known species of generaSymphytopterusandPraeaulacusare provided. By comparing the wings ofSymphytopterus, we find that the change of the veins length is the main interspecific difference andS. liasinusmay occupy the most basal position inSymphytopterus.

Two new genera and two new species of fossil rhopalid, Miracorizus punctatus gen. & sp. nov. and Longiclavula calvata gen. & sp. nov., are described and illustrated. They were collected from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. This is the earliest fossil record of the family Rhopalidae in the world.

First Time

New findings of pollen cones of Sorosaccus sibiricus Prynada were studied in detail from the Aalenian—Bajocian Prisayan Formation of two localities in the Irkutsk coal basin (Ust’-Baley and Vladimirovka). Specimens of S. sibiricus previously described from Ust’-Baley (Heer, 1876) were reexamined. It was revealed that S. sibiricus differs from other species of Sorosaccus in a shape of the apical (free from the microsporangia) part of the microsporophylls. Microsporophylls of S. sibiricus consist of a petiole and a wide-oval distal lamina with acute apex, commonly bending upward. The lamina was often folded and became lanceolate, linear, or fan-shaped with uneven to toothed margin. Microsporangia (6—8) are oval in outline, helically attached to the petiole. Pollen grains were extracted from S. sibiricus microsporangia for the first time. They are oval to boat-shaped in outline, monosulcate and differ from other known Sorosaccus pollen grains by the verrucate surface of the exine. The diagnosis of the species Sorosaccus sibiricus is emended.

Important Site

In Siberia, there are numerous Jurassic and Cretaceous locations abundant in fossil insects. The Teete outcrop (renamed Kempendyay) located in the eastern Siberia (Russia) is an important site due to its age estimated to beginning of the Lower Cretaceous as well as its high taxa diversity and very good specimen preservation. However, it is poor in fossils of the Limoniidae. Study of the rare Tipulomorpha material from the Teete locality (= Kempendyay) is presented herein and two new species are described and illustrated. One of them belongs to the family Pediciidae, Prearchitipula ryszardi sp. nov., and the second to the family Limoniidae, Eotipula wieslawi sp. nov. Both species are dedicated to two well-known Polish specialists of fossil Diptera Nematocera.

Protobrachyceridae, which is an archaic representative of the Brachycera with only one known genus and two species, Protobrachyceron liasinum Handlirsch, 1920 and P. zessini Krzeminski & Ansorge, 2000, has been described from the lower Toarcian of Germany. The family can be distinguished by the following characters: vein Sc ending at midwing, both vein R4 and cell d distinctly shorter than vein M1 in length, vein CuP well visible, mouth of cell r1 narrow, five posterior cells widely open, cells m3 and cup narrowly open.

Unidentified Species

The study of leeches from Lake Gusinoe and its adjacent area offered us the possibility to determine species diversity. As a result, an updated species list of the Gusinoe Hirudinea fauna (Annelida, Clitellata) has been compiled. There are two orders and three families of leeches in the Gusinoe area: order Rhynchobdellida (families Glossiphoniidae and Piscicolidae) and order Arhynchobdellida (family Erpobdellidae). In total, 6 leech species belonging to 6 genera have been identified. Of these, 3 taxa belonging to the family Glossiphoniidae (Alboglossiphonia heteroclita f. papillosa, Hemiclepsis marginata, andHelobdella stagnalis) and representatives of 3 unidentified species (Glossiphoniasp.,Piscicolasp., andErpobdellasp.) have been recorded. The checklist gives a contemporary overview of the species composition of leeches and information on their hosts or substrates. The validity of morphological identification of each taxon has been verified by phylogenetic approach with a molecular marker adopted for a DNA barcoding of most invertebrates.
