Gastropod mollusks from the Hauterivian of Ulyanovsk (Volga Region): 2. Genera Khetella Beisel, 1977 and Cretadmete gen. nov.

The diagnosis of the genus Khetella Beisel, 1977 is emended, and a new genus, Cretadmete, is described. Two new species belonging to these genera, K. trautscholdi and C. neglecta, are established from the Upper Hauterivian of Ulyanovsk (Volga Region).     

Scale insects (Homoptera, Coccinea) of the volga area: III. Nudicauda gen. n. and other mealybugs from astrakhan

The present paper is the third part of a revision of the fauna of the Volga Area. Five species new for the Volga Area, including four new for Russia are recorded. Nudicauda gen. n. is erected with type species Nudicauda nigra (Matesova, 1957) (comb. n.). The new genus differs from other genera of mealybugs in a complex of characters and mainly in the presence of very specific oral rim tubular ducts with a broad flat ring and in an unusual ovisac with the opening over posterior tergites of the female body. In addition to the type species, N. orientalis (Borchsenius, 1949) and N. salina (Matesova, 1981) (comb. n.) are also included in the new genus. N. nigra and N. orientalis are considered as separate species, contrary to Danzig (1980). All the three species of the new genus are redescribed and illustrated. The structure of the tubular ducts of the genus Humococcus Ferris, 1953 is briefly discussed and illustrated.     

Key to Protoceratopoid vertebrae (Ceratopsia, Dinosauria) from Mongolia

A detailed nomenclature and a measurement system for vertebrae of Mongolian Protoceratopoidea are proposed. A key to vertebrae that allow the determination of the region of the vertebral column and the serial number of each vertebra within each region is developed. Distinctions in vertebral column between two protoceratopoid families (Protoceratopidae and Bagaceratopidae) are summarized.     

Description and DNA barcoding of Tipula ( Pterelachisus) recondita sp. n. from the Palaearctic region (Diptera, Tipulidae)

Tipula (Pterelachisus) recondita Pilipenko & Salmela, sp. n. is described. The new species is collected from two localities: Finland, Kittilä (North boreal ecoregion) and Russia, Primorski kray (Zone of temperate broadleaf and mixed forests). Although variation in the structure of male hypopygium between the Finnish and Russian populations is observed, DNA barcode sequences differ only by three nucleotides (0.2 % K2P distance), supporting presence of one widespread species. K2P minimum distances between the new species and 17 other species of the subgenus range from 5.3 to 15.8 % (mean 8.8 %). The new species is forest-dwelling, known from an old-growth herb-rich forest (Finland) and Quercus mongolica forest (Russia). The new species is perhaps closest to Tipula (Pterelachisus) imitator Alexander and in lesser extent to Tipula (Pterelachisus) pauli Mannheims; the inner gonostylus of both species are illustrated.     

A large-scale introgression of genomic components of Brassica rapa into B. napus by the bridge of hexaploid derived from hybridization between B. napus and B. oleracea

Brassica rapa (AA) has been used to widen the genetic basis of B. napus (AACC), which is a new but important oilseed crop worldwide. In the present study, we have proposed a strategy to develop new type B. napus carrying genomic components of B. rapa by crossing B. rapa with hexaploid (AACCCC) derived from B. napus and B. oleracea (CC). The hexaploid exhibited large flowers and high frequency of normal chromosome segregation, resulting in good seed set (average of 4.48 and 12.53 seeds per pod by self and open pollination, respectively) and high pollen fertility (average of 87.05 %). It was easy to develop new type B. napus by crossing the hexaploid with 142 lines of B. rapa from three ecotype groups, with the average crossability of 9.24 seeds per pod. The genetic variation of new type B. napus was diverse from that of current B. napus, especially in the A subgenome, revealed by genome-specific simple sequence repeat markers. Our data suggest that the strategy proposed here is a large-scale and highly efficient method to introgress genomic components of B. rapa into B. napus.     

Lamprops donghaensis sp. n. (Crustacea,Cumacea, Lampropidae), a new species from Korean waters

A new species of Cumacea belonging to the genus Lamprops Sars was collected from the East Sea of Korea. This new species resembles Lamprops comatus Zimmer, Lamprops carinatus Hart, Lamprops flavus Harada, Lamprops pumilio Zimmer, Lamprops tomalesi Gladfelter, and Lamprops obfuscatus (Gladfelter) in lacking lateral oblique ridges on the carapace and lateral setae on the telson. The new species, however, is distinguished from its congeners by having a dorsal concave groove and a lateral rounded depressed area on pereonite 2. The new species is fully illustrated and compared with related species. A key to the world Lamprops species lacking lateral ridges on the carapace is also provided.     

Lycopodium alkaloids from Lycopodium obscurum L. f. strictum

Two new Lycopodium alkaloids, strictumines A (1) and B (2), along with 18 related known compounds were isolated from the whole plant of Lycopodium obscurum L. f. strictum. The structures of the new compounds were established by spectroscopic methods and chemical transformation. This is the first report on chemical constituents of the title plant. All the isolates were evaluated for their inhibitory activity against acetylcholinesterase (AChE), and only a few were found to show slight bioactivity.     

Inonotus taiwanensis sp. nov. (Basidiomycota) from Taiwan

Inonotus taiwanensis (Hymenochaetales) is described as a new species collected from southern Taiwan, and all specimens grew on the trunk of Trema tomentosa. This new species is characterized by having resupinate, effuse-reflexed to pileate basidiocarps, bright yellow context, long setal hyphae in context and trama, setae in hymenium and trama, and fairly small basidiospores. Maximum likelihood and Bayesian inference phylogenies inferred from both sequences of 28S and internal transcribed spacer (ITS) region of rDNA indicated that I. taiwanensis forms a distinct clade within Inonotus, and the species is sister to I. tricolor. The comparison of morphological differences among I. taiwanensis and some closely related Inonotus spp. is presented.     

Larinus berti sp. n. (Coleoptera,Curculionidae, Lixinae) from North Africa

A new species, Larinus berti sp. n. is described from Morocco and assigned to subgenus Cryphopus Petri, 1907 (Curculionidae: Lixinae; Lixini). Diagnostic characters of the new species are large size, elongate-ovate body, bisulcate sub-quadrangular rostrum, triangularly raised dorsum of rostrum, flat subgena and submentum, Y-shaped apodeme of sternite VIII of female and thin nodulus of spermatheca.     

Xylodon subflaviporus sp. nov. (Hymenochaetales,Basidiomycota) from East Asia

Xylodon subflaviporus (Hymenochaetales, Basidiomycota) is described as a new species collected from tropical and subtropical regions of East Asia. This new species is characterized by resupinate basidiocarps, a poroid hymenophore, pseudodimitic hyphal system, nodose-septate hyphae, four types of cystidia (capitate, acicular to cylindrical, subulate to ventricose, and apically-encrusted), and thin-walled, colorless, smooth and ellipsoid basidiospores. Bayesian, Maximum Likelihood and Maximum Parsimony algorithms were used to construct phylogenies inferred from the internal transcribed spacer (ITS) region of rDNA. Morphological and molecular studies, along with intercompatibility tests, confirmed the independent status of this species. Also, based on morphological and molecular evidence, six new combinations of Xylodon are proposed to accommodate species originally classified under Hyphodontia s.l., i.e. X. bubalinus, X. chinensis, X. mollissimus, X. nongravis, X. reticulatus and X. subtropicus. A key to known species of Hyphodontia s.l. with poroid, irpicoid or raduloid hymenophores is provided for the convenience in identification.     

Proposal to replace the illegitimate genus name Prescottia Jones et al. 2013 with the genus name Prescottella gen. nov. and to replace the illegitimate combination Prescottia equi Jones et al. 2013 with Prescottella equi comb. nov

Recently we proposed that Rhodococcus equi (Magnusson 1923) Goodfellow and Alderson 1977 be transferred to a novel genus, Prescottia, as Prescottia equi comb. nov. However, in accordance with Principle 2 and Rule 51b(4) of the Bacteriological Code (1990 Revision), the bacterial genus name Prescottia Jones et al. 2013 is deemed illegitimate as this name has been used previously for a plant genus within the family Orchidaceae. Consequently, a new genus name, Prescottella gen. nov. is proposed for the bacterial taxon and a new combination Prescottella equi comb. nov. is proposed for the type species.     

A new remarkable subterranean beetle of the Rhodopes: Paralovricia gen. n. beroni sp. n. belonging to Lovriciina new subtribe (Coleoptera, Carabidae, Trechinae, Bembidiini)

Paralovricia gen. n. beroni sp. n., belonging to the new subtribe Lovriciina, is described from two caves in the Western Rhodopes (Bulgaria): Kraypatnata peshtera, near Smilyan Village (Smolyan Municipality) and Snezhanka, near Peshtera Town (Peshtera Municipality). Three currently known genera, Lovricia Pretner, 1979, Neolovricia Lakota, Jalžić & Moravec, 2009 and Paralovricia gen. n. represent a monophyletic unit supported by important synapomorphies that allows to propose the establishment of the new subtribe Lovriciina, characterized by the following characters: last maxillary palpomeres very long and narrow, basal angles of pronotum without seta, elytra without discal setae, elytral umbilicate series of nine pores in which the main pores are the 2nd, 6th and 9th, apical recurrent striole absent and mesotibial apex expanded outward. Its systematic position within the subfamily Trechinae (sensu Lorenz 2005) is discussed and Lovriciina is placed near Anillina. Key to the genera of the subtribe is proposed. Distribution data and zoogeographical hypotheses are discussed.
