Morphological Investigations

A new cymbelloid diatom species from the genus Cymbopleura (Krammer) Krammer is described on the basis of molecular and morphological investigations. Cymbopleura natellia Glushchenko, Kulikovskiy & Kociolek, sp. nov. is, on the basis of results with molecular data, close to C. naviculiformis (Auerswald ex Heiberg) Krammer. The two species differ both by molecular distance and morphological features. Morphologically, C. natelliasp. nov. is compared with several other species in the genus. This work is a pioneer investigation of cymbelloid taxa using molecular tool from Transbaikal area.

A New Species

A new species, Envekadea vranaensis Caput Mihalić, Galović & Levkov sp. nov., is described from Holocene sediments of Lake Vrana, Croatia. The new species is characterized by linear-lanceolate valves with broadly capitate apices and is 40.0–67.5 μm long and 7.5–9.0 μm wide. Based on its morphological features it is similar to E. hedinii and E . pseudocrassirostris. Also, E. vranaensis shares morphological and ultrastructural features with E . vanlandinghamii, from which it can be differentiated by the valve outline, shape of the apices, stria density and the shape of proximal raphe endings. We present stratigraphic occurrence and ecological preferences for E . vranaensis based on associated paleoecological proxies.

A New Species

AbstractAdults of Lasiotocus lizae Liu, 2002 (Monorchiidae) were found in the mullet Liza longimanus (Günther) from Tonkin Bay, near Cat Ba Island, Vietnam. In this region, flukes belonging to the genus Paucivitellosus (Bivesiculudae) were found in Liza subviridis (Valenciennes), Liza engeli (Bleeker) and Valamugil seheli (Forskåi). Results of investigations showed that morphological features of L. lizae (like L. glebulentus Overstreet, 1971) do not meet the criteria of the genus Lasiotocus. In addition, L. lizae is highly differentiated from other species of Lasiotocus from which molecular data were obtained, including L. arrhichostoma Searle, Cutmore et Cribb, 2014 and L. typicum (Nicoll, 1912). Phylogenetic analyses revealed that L. lizae differs considerably from other species of the genus Lasiotocus presented in the GenBank database. We have identified a new species of the genus Paucivitellosus–P. vietnamensis sp. n. – from L. subviridis, which differs from P. fragilis Coil, Reid et Kuntz, 1965 by metrical and molecular (18S rRNA) data, and from P. hanumanthai Mani, 1989 by metric features. Our results also show considerable molecular differentiation between P. vietnamensis sp. n. and Paucivitellosus spp. recovered from L. engeli and V. seheli in Vietnam.

Planothidium sheathii sp. nov., a new species from rivers in California, USA, is described based on light and scanning electron microscopy. P. sheathii has broadly lanceolate to elliptic valves with obtusely rounded apices and a unique combination of morphological features, as follows: 1) cavum with broad hood aperture that flares out at the valve margin with open borders fused with the neighboring virgae on SV, 2) multiseriate striae, composed of five to six rows of same sized areolae on both valves, interrupted at valve mantle junction, and 3) areolae groups on valve mantle, with rounded areolae on RV, and rounded and elongated areolae on SV. Valve morphology of P. sheathii is discussed in comparison with similar freshwater taxa, from which the new species is clearly distinct.

A new species of flesh fly, Sarcophaga karakoncolos sp. n., is described based on a single adult male from Turkey (Isparta Province, Anatolia), characterised by its very large size (almost 22mm in body length) and by a unique combination of morphological features. These, together with available molecular data, do not support inclusion of the new species in any of the currently recognised subgenera of Sarcophaga, and it is placed in a new subgenus, Hadroxena subg. n.

A New Species

A new wood-rotting fungal species, Punctularia bambusicola, is proposed based on a combination of morphological features and molecular data. The species is characterized by resupinate, lilac to purple basidiomata, pink to rose tuberculate hymenial surface, monomitic hyphal system with clamped generative hyphae, yellowish to brown dendrohyphidia and ellipsoid basidiospores measuring 6.5–8.5 × 3.5–5 µm. Phylogenetic analyses of combining ITS and LSU nrRNA gene regions demonstrated that P. bambusicola forms a single lineage sister to P. atropurpurascens with strong statistical supports (100% BS, 100% BT, 1.00 BPP).

A new species from the genus Placoneis (Bacillariophyceae: Cymbellales) is described on the basis molecular and morphological data. Placoneis cattiensis Glushchenko, Kezlya, Kulikovskiy & Kociolek sp. nov. is described from soil collected from the bottom of a dry, temporary stream in the forest of Сát Tiên National Park in Vietnam. On the basis of molecular data our new species appears to be more closely related to two strains of Placoneis previously identified as P. elginensis. However, P. cattiensis shows lower statistical support with two strains of P. elginensis on the basis ML. Additionally, P. cattiensis is distinguished from P. elginensis on the basis of morphological features such as the shape of the valve, breadth and density of areolae and striae. Comparisons of P. cattiensis with other similar species are given.

Abstract A new species of micromorphic articulate brachiopod (Rhynchonellida) Lambdarina jugowiensis sp. nov., from the upper Visean (Sokolec Beds) of central Sudetes, SW Poland, is described. The studied specimens are calcified, what makes them unique in respect of their state of preservation. The material is represented by a full range of growth stages; from brephic to gerontic. Based on its morphological features and the palaeogeographical distribution of all its known species, two main evolutionary lines are proposed for the genus; the Australian and the European ones. Lambdarina was widely distributed in the equatorial-tropical waters of marginal seas of the Palaeotethys Ocean, mostly during Mississippian time.

Leptochelia Vatulelensis(Crustacea: Tanaidacea), A New Species From Anchialine Caves of the South-Western PacificLeptochelia vatulelensisn. sp., discovered on the small islands of Vatulele (Fijian group) and Ouvéa (Loyalty Islands, New Caledonia), is described and illustrated. The new species is distinguished from the others of the"Leptochelia-dubiagroup" (to which it is generally similar) by the following combination of morphological characteristics: (1) the presence of three to four distal setae on the maxilliped basis; (2) merus of pereopods III and IV with only a distosternal seta; (3) endopod of the uropods formed of four (rarely three) articles; (4) males with two (sometimes three) relatively short aesthetascs on the first five articles of the antennular flagellum; (5) male cheliped with a diminished dimorphism; (6) males with a vertical comb-row of setae on the cheliped propodus. Although it inhabits inland, anchialine caves, the new species lacks morphological features that are characteristic of some cave species.

Abstract Coomansus batxatensis sp. nov., recorded from Vietnam, is described and illustrated and its phylogenetic relationship within the Mononchida is analysed. The molecular data (18S and 28S ribosomal DNA) are provided for the new species. The new species is characterized by small body size (body length, L = 0.7–0.9 mm); buccal cavity sub-rectangular in shape, flattened at base, 21–24 × 12–13 μm or 1.9 (1.7–2.0) times as long as wide; posterior position of dorsal tooth apex (59–63% from the base of buccal cavity); pars refringens vaginae with faint and small (2.5 × 1.7 μm) teardrop-shaped pieces, short pars distalis vaginae; and males with short spicules (50–51.5 μm) with rounded head and conical blade part. The new species is close to Coomansus parvus but differs from it by the smaller buccal cavity size, more posterior position of the dorsal tooth apex, longer tail and presence of males. An updated identification key to Coomansus species and a compendium of all the species known are presented.
