G.N. Buzhinskaja. 2017. Descriptions of Pedinosoma curtum Reibisch from North-West Pacific and a late larva of Pedinosoma polaris sp. nov. from the Arctic Basin (Polychaeta: Phyllodocida: Lopadorhynchidae). Zoosystematica Rossica, 26(1): 3–10.

Abstract

A specimen of the pelagic polychaete Pedinosoma curtum Reibisch (Lopadorhynchidae) is described from the North-West Pacific. It differs from the Atlantic specimens of the species in longer aciculae, larger antennae as compared with palps and pigmentation of the dorsal cirri. A late larva of Pedinosoma рolaris sp. nov. is described from plankton of the Arctic Basin (depth 2000–1000 m). The distinctive characters of the new species are: podial lobes, aciculae and compound chaetae present on the tentacular segment, the absence of cirrophores of the tentacular and ventral podial cirri, the podial cirri arranged on the podial process, and a well-developed pygidium bearing anal cirri. An additional diagnosis of the genus Pedinosoma Reibisch is provided.

Abstract

Two rare catenulid species, Myostenostomum vanderlandi Rogozin, 1992 and M. bulbocaudatum Luther, 1960, were found in reservoirs of the Volga-Kama Biosphere Reserve (Middle Volga Basin, Russia) during a survey of microturbellaria in 2013. Both the species were recorded for the first time in the fauna of the Volga Basin, while M. vanderlandi, previously known only from water bodies of South America, was first found in the Holarctic. The morphological characters and geographical distribution of the species are discussed.

Abstract

A description of Monhystrella andreana sp. nov. from brackish water lake Tierra del Fuego, Chile, is given. The new species differs from the most morphologically close M. macrura (de Man, 1880) mainly in shorter tail and pharynx (esophagus), and in longer spicules.

V.I. Gontar’. 2017. New species of the genus Isoschizoporella (Bryozoa: Gymnolaemata: Cheilostomatida: Eminooeciidae) from the Weddell Sea. Zoosystematica Rossica, 26(2): 209–211.

Abstract

A new species, Isoschizoporela marisweddelli sp. nov., from the bryozoan order Cheilostomatida was described within the genus endemic for Antarctic waters. Fragments of colonies of the species were found in the Weddell Sea by the German Antarctic Expedition ANT XIII/3 on the research vessel “Polarstern” in 1996. The species is distinguished from the other species of Isoschizoporella by the incrusting colony, elongate, hexagonal and convex autozooids, semicircular primary orifice with shallow sinus, strongly convex avicularian chamber, avicularium with semicircular mandible, and additional avicularium on frontal surface of autozooid. The species belongs to the infraorder Ascophora, superfamily Schizoporelloidea.

S.Yu. Gagaev. 2017. Fossil impressions of pectinariid tubes (Polychaeta) in Miocene sediments of the Sakhalin Island. Zoosystematica Rossica, 26(2): 212–214.

Abstract

The fossil impressions of tubes belonging to the bristle worms of the family Pectinariidae and probably the genus Pectinaria Savigny, 1818 was found at the coastal cliffs of the Tartar Strait (Southern Sakhalin) in deposits of the late Miocene Kurasi Formation. Rare mentions of findings of impressions of the polychaetes tubes perhaps may be explained by the fact that such impressions are misidentified as fossils of animals from other higher taxa. Some new data on the bionomics of the recent pectinariids are given and some taphonomical aspects of the group are considered.

E.V. Soldatenko. 2017. Morphological diversity of stylets in Kolhymorbis (Mollusca: Pulmonata: Segmentinidae). Zoosystematica Rossica, 26(2): 215–222.

Abstract

The taxonomy of freshwater pulmonates (Hygrophila) relies heavily on morphology of their reproductive system, most notably on the characters of the copulatory apparatus. For this reason, taxonomically important components of the copulatory apparatus such as penial stylets have always received much attention in the morphological studies on Hygrophila. The present study describes the stylets of Kolhymorbis bogatovi Zatrawkin et Moskvicheva in Zatrawkin, 1985 and K. shadini Starobogatov et Streletzkaja, 1967 and compares them with the previously described stylet of K. angarensis (Dybowski et Grochmalicki, 1925). The lengths of the stylets vary within the genus from 20 to 30 μm. In K. bogatovi, the stylet is a trough-shaped plate with a distal portion twisted 110° counterclockwise with respect to the proximal portion. The stylet of K. shadini is also a trough-shaped plate, but its walls are curved in such a way that the stylet forms a hollow cone with a beveled tip. The slit between the opposite lateral flanks of the stylet is wide proximally, but narrows down distally. The stylets of all three Kolhymorbis species differ markedly in their shape. The trough-shaped stylet of K. angarensis most likely represents the plesiomorphic state; the stylet of K. bogatovi may have originated from this type of stylet by increasing the curvature of the walls and counterclockwise twisting of the distal portion of the stylet. The cone-shaped stylet of K. shadini may have evolved from the plesiomorphic type by widening of the proximal portion and by even more pronounced curving of the walls throughout the length of the stylet without distal twisting. The penial stylets of Kolhymorbis species are compared with those of Palaearctic genera of the family Segmentinidae Baker, 1945 and the taxonomic utility of the stylet characters is evaluated.

P. Rosa. 2017. Review of the Palaearctic species of the genus Colpopyga (Hymenoptera: Chrysididae) with description of a new species. Zoosystematica Rossica, 26(2): 294–306.

Abstract

Colpopyga Semenov, 1954, a chrysidid genus of the tribe Elampini (Chrysididae: Chrysidinae) with four Palaearctic and one Nearctic species, is reviewed. The study of internal urites (Noskiewicz & Lorencova, 1963) and new molecular data (Niehuis, pers. comm.) show a generic status of Colpopyga, which is more related to the genus Holopyga Dahlbom, 1854. A new species, Colpopyga nesterovi sp. nov. from Kazakhstan, is described and illustrated; it is easily recognizable by the red-coppery body coloration and shallow, small and sparse punctures. The status of the subspecies Hedychridium flavipes temperatum Linsenmaier, 1959 is updated to species level in the genus Colpopyga (comb. nov.). New generic combinations are also proposed for C. aureiventris (Mercet, 1904), comb. nov. and C. crassa (Bohart, 1978), comb. nov. (all from the genus Hedychridium). The lectotype of Hedychridium flavipes var. cyanomaculatum Trautmann, 1927 is designated.

Abstract

The taxonomic history for all species of a species-rich genus of the Chloropidae (Diptera) is briefly presented for the first time, by the example of the genus Elachiptera Macquart, 1835. Here, all names of the species-group ever combined with the generic name Elachiptera are listed together with the references and the first page of their descriptions, their first transfer into the valid genus, their senior and junior synonyms and further important references to their taxonomical status. In addition, all names of the genus group that have ever been associated with these species names are listed together with their type species. Thirty new combinations are introduced in order to transfer species from Melanochaeta Bezzi, 1906 (a synonym of Oscinella Becker, 1909) to the valid genera Lasiochaeta Corti, 1909 and Gampsocera Schiner, 1862. The known zoogeographical distribution of each of the 81 valid Elachiptera species and 74 valid species in other genera is briefly summarized. Selected exemplary data on larval habitats of Elachiptera are discussed.

Abstract

Two new species of the genus Chaetocladius are described, C. (s. str.) coppai sp. nov. as male adult and C. (s. str.) diai sp. nov. as male adult and pupa. The descriptions are based on the material collected at glacial alpine springs and small streams located in the Maritime French Alps and the Swiss Alps for C. coppai sp. nov., and the Mount Lebanon range for C. diai sp. nov. According to the characters of the adult males, C. coppai sp. nov. belongs to the laminatus-group, while C. diai sp. nov. is close to C. elegans Makarchenko et Makarchenko, 2001. The comments on the taxonomic position, ecology and geographical distribution of the new species are given.

A.A. Przhiboro. 2017. New data on psammorheophilous Limoniidae (Diptera)of NE European Russia. Zoosystematica Rossica, 26(2): 381–391.

Abstract

The new records of five species of Limoniidae (Diptera) are given: Rhabdomastix beckeri (Lackschewitz, 1935) and Scleroprocta pentagonalis (Loew, 1873) are recorded for the first time from Russia; the first reliable record of Eloeophila mundata (Loew, 1871) from Russia is given; Hexatoma fuscipennis (Curtis, 1836) and H. nubeculosa nubeculosa (Burmeister, 1829) are recorded for the first time from NE European Russia. It is found that the larvae of four species, R. beckeri, S. pentagonalis, E. mundata and H. fuscipennis, in NE European Russia (Perm Territory and Udmurtia) are aquatic psammorheophilous forms inhabiting sandy sediments at the bottom of rivers in sites with strong current. Previously the larvae in these genera and in three of these species have been considered mostly as semiaquatic forms that develop in substrata near the water margin. Larval habitats of the four species in the study area are characterized. The photographs of diagnostic characters of adult males of these species are given.

O.A. Diripasko & T.A. Zabroda. 2017. Morphometric variability in round goby Neogobius melanostomus (Perciformes: Gobiidae) from the Sea of Azov. Zoosystematica Rossica, 26(2): 392–405.

Abstract

A total of 38 morphometric characters of the round goby Neogobius melanostomus melanostomus (Pallas, 1814) were studied in its native range in the Sea of Azov. The aim was to assess joint effect of sexual dimorphism and size variability on overall variability within groups of samples (populations) using appropriate methods of traditional statistical analysis (one-dimensional and multivariate statistics). Sex and size-dependent variability was studied based on model samples of males and females of different size. Most of the studied morphometric characters of round goby from the Sea of Azov demonstrated statistically significant sex- and size-dependent in-group variability. The pattern of the variability suggests that, for a comparison of round goby from different sea regions and between populations, separate samples of males and females within the range 9–13 cm SL should be examined in order to minimise the effect of the size and sex factors. The approach of searching for the most informative size range could be useful not only for further studies of infraspecific variation but for comparisons between morphologically close gobiin species.

Abstract

Svetlana N. Myartseva started her extensive study of Mexican Chalcidoidea in 1998 as a professor of the Universidad Autónoma de Tamaulipas in Ciudad Victoria, Mexico. From 2000 to 2016 she published four monographs, 15 book chapters and 91 journal articles on taxonomy, fauna and biology of Mexican Chalcidoidea. She described one new genus and 140 species belonging to five families: Aphelinidae (117 species in 10 genera), Encyrtidae (15 species in 6 genera), Eulophidae (5 species in 2 genera), Eupelmidae (1species) and Trichogrammatidae (1 species). The most valuable contribution by S.N. Myartseva was to the knowledge of the family Aphelinidae and its largest genus Encarsia Förster. As results of her investigations, the number of species in this genus in the Mexican fauna was increased from 30 in 2000 to 112 in 2016; 70 species were described by S.N. Myartseva as new. Currently, 14 genera and 214 species of Aphelinidae (1 genus and 117 species from 10 genera were described as new) are known to occur in Mexico which is almost three times more species than were known in 2000. A complete list of new taxa of Chalcidoidea described by S.N. Myartseva from Mexico and all her publications on Mexican Chalcidoidea are provided.
