Late Miocene Indarctos (Carnivora: Ursidae) from Kalmakpai Locality in Kazakhstan

The big bear from the genus Indarctos is studied for the Neogene fauna of Kazakhstan for the first time. Material is represented by the isolated М1 found at the Late Miocene deposits (MN13) of the Karabulak Formation of the Kalmakpai River (Zaisan Depression, Eastern Kazakhstan). Tooth size and its morphology suggest this finding to be referred to I. punjabiensis, which was widely distributed in Eurasia.

The Features of Production Processes in the Lakes of the Valaam Archipelago

The paper reports the characteristics of primary production and destruction processes in small lakes of the Valaam archipelago. The study was carried out on 11 small lakes where the natural regime of functioning is preserved. Studied lakes have different origins, morphometric and hydrochemical parameters. Investigated lakes were characterized by high concentrations of nutrients, especially in the bottom layers. Structure of phytoplankton community differed between lakes. In total, 306 species of phytoplankton had been found in the lakes of the Valaam archipelago. The highest species richness was registered for green algae, diatoms, euglenids and cyanoprokaryota. The lakes of the Valaam archipelago differed in species composition, ratio of taxonomic groups, phytoplankton abundance and biomass. Abundance of phytoplankton and biomass varied from 0.1 to 676.6 million cells/l and from 0.1 to 105.2 mg/ l, accordingly. A wide range of photosynthetic rate (from 0.0 to 4.3 mgO2/ l day and destruction (from 0.0 to 4.2 mgO2/l day) had been shown for all studied lakes. High values of the maximum primary production (Amax) were typical for Igumenskoe, Leschevoe, Krestovoe and Vitalevskoe Lakes, low values were recorded in lakes Simnyahovskoe, Antonievskoe and Nikonovskoe. Mean values Amax (1.14 ± 0.08 mgO2/l day) and maximum destruction Rmax (1.19 ± 0.07 mgO2/l day) were high in all the lakes. In most cases (90%), the maximum photosynthesis rate was registered in the water layer from a surface down to a lower border of the Secchi depth. Data on chlorophyll α content in small lakes of the Valaam archipelago are provided for the first time. It was shown that most of the lakes are mesotrophic with signs of eutrophia (TSI 50–68).

On the taxonomic position of the genera Paralusanda Synave, Paramangola Synave, Chondroptera Bergroth, and Neolollius Muir (Hemiptera: Auchenorrhyncha: Fulgoroidea: Nogodinidae)

Previously treated as members of the family Issidae and currently without clear status, four genera are transferred to the family Nogodinidae: genus Paralusanda Synave, 1956 is transferred to the tribe Mithymnini Fennah, genera Chondroptera Bergroth, 1910 and Neolollius Muir, 1921 – to the tribe Tongini Kirkaldy, and genus Paramangola Synave, 1956 – to the tribe Epacriini Fennah. Male and female genitalia of Paralusanda sinuatipennis Synave, 1956 and fore and hind wings of Paramangola schmitti Synave, 1956 are illustrated for the first time. Notes on ecology of P. sinuatipennis are made.

Clypeosmilus centrodasus gen et sp. nov., a new genus and species of the family Issidae (Hemiptera: Fulgoroidea) from Northern Vietnam

Clypeosmilus centrodasus gen. et sp. nov. is described from Northern Vietnam. The genus is closely related to Eusudasina Yang, 1994 and Tapirissus Gnezdilov, 2014 according to fore wing reticulate venation and flattened laterally postclypeus.

New taxa of the subfamily Meconematinae (Orthoptera: Tettigoniidae) from Africa and adjacent islands

History of the taxonomic study of Afrotropical and Madagascan Meconematinae is briefly discussed. The subtribe Acilacridina subtrib. nov. is established for a few African genera of Meconematini. Twenty six smaller new taxa of Meconematini [Kamerula korupi gen. et sp. nov., K. kameruni sp. nov., Parakamerula irisovi gen. et sp. nov., Brachyamytta rapidoaestima speculifera subsp. nov., Naskreckia gen. nov., Xiphidiola (Deinodiola) adunca subgen. et sp. nov., X. (D.) lobulata sp. nov., X. (D.) dja sp. nov., X. (D.) quadrimaculata immaculata subsp. nov., X. (Hemidiola) emarginata subgen. et sp. nov., X. (H.) minuta sp. nov., Paracilacris (Neacilacris) latiexcisa subgen. et sp. nov., Anaroegas subgen. nov.] and Phisidini [Afrophisis (Jinkevania) parva subgen. et sp. nov., Mirabiphisis subgen. nov., Longiphisis gracilis gen. et sp. nov., L. media sp. nov., Breviphisis robusta gen. et sp. nov.] are described from Cameroon, South Africa and Madagascar. Amyttosa mutillata bubiana (Bolivar, 1906), stat. nov. and Xiphidiola aliquantula nigrospinosa Bolivar, 1906, stat. nov. are restored from synonymy to A. mutillata (Karsch, 1890) and X. aliquantula (Karsch, 1893) as subspecies of these species; one former genus is considered as the subgenus Paradecolya Jin, 1992, stat. nov. within the genus Brachyphisis Chopard, 1957; several morphological, taxonomical and geographical remarks on A. mutillata and some other taxa are given.

Mexican species of Cylloceria Schiødte (Hymenoptera: Ichneumonidae: Cylloceriinae)

Seven species of the genus Cylloceria are found to occur in Mexico. Of them, C. morelia Humala et Khalaim sp. nov. is described as new, and two species, C. alvaradoi Gauld and C. rubrica Dasch, are recorded from Mexico for the first time. New data on distribution of four other species in Mexico are provided. Cylloceria alvaradoi is also recorded for the first time from Panama. An identification key to seven Mexican species of Cylloceria is given.

Long-term Monitoring of Breeding and Transient Bird Populations on the Courish Spit of the Baltic Sea

Since 1957, Biological Station Rybachy performs long-term monitoring of timing of spring and autumn migrations, timing of breeding and postfledging movements, dynamics of numbers of breeding and transient bird populations by standardized trapping in Rybachy-type funnel traps on the Courish Spit on Baltic coast. The results of monitoring strongly suggest that take place the long-term fluctuations of the timing migrations and numbers of local and transient populations. Current climate warming leads to earlier spring arrival not only in species that spend their winter within Europe, but also in long-distance African migrants. Colder weather, conversely, delays spring passage on 15–30 days. There are reasons to believe that climate change has influenced not only the timing of arrival to breeding grounds but also to the time of migratory departure from the winter quarters, both European and African ones. Climate change exerts a much smaller direct influence on the timing of autumn migration; the latter is more dependent on the timing of breeding. Earlier spring arrival usually leads to earlier breeding in the Baltic bird populations, which in its turn enhances breeding performance and leads to production of more young birds and thus to populations growth. Long-term monitoring of bird populations by Rybachy-type stationary traps is a powerful tool of studying the impact of climate on avian phenology and numbers.

Identification Key to the Intracontinental Species of the Genus Diaptonema (Nematoda: Monhysterida: Xyalidae) with a Description of New Species D. borkini sp. nov.

Until recently, the system of the family Xyalidae was extremely complicated. The characters of the genera Theristus, Cylindrotheristus, Mesotheristus, Pseudotheristus, Mongolotheristus, and others were mixed up. Many species changed their generic assignment more than once. The most recent revision (Venekey et al. 2014) resulted in the fact that in intracontinental water bodies two species only preserved their independence: Daptonema and Sacrimarinema. Genera Cylindrotheristus, Mesotheristus, Mongolotheristus, Penzancia were partially reduced to synonyms of Daptonema. The basic character in taxonomy of genera is terminal setae. This cannot be used in some cases as some individuals in some populations lack terminal setae. Development of the system of the family Xyalidae and genus Daptonema, in particular, is possible under consideration of such characteristic as spicule form and presence of tail papillae. The hermaphrodite specimen of D. borkini sp. n. is discussed separately. The article provides an identification key to intracontinental species of the genus Daptonema. The key shows the species to be found in intracontinental water bodies. The species recorded in rivers (as a rule, in estuaries and lower parts of rivers) are not taken into account, as they seem to be the marine species which are capable to survive in significantly desalinated water. The article provides the description of new species D. borkini sp. n., which is similar in morphology to D. salinae Gagarin et Gusacov, 2014 and D. limnobia Wu et Liang, 2000. The key is supplemented with the Table of the main characteristics of all intracontinental species (males) of the genus Daptonema.
