Notes on the phylogenetic relationships of planthoppers of the family issidae (Hemiptera,Fulgoroidea) of the Western Palaearctic fauna,with descriptions of two new genera

Seven groups of genera are distinguished in the subtribe Issina Spinola. The new genera Apedalmus gen. n. (the type species Falcidius abruzicus Dlabola, 1983) and Thalassana gen. n. (the type species: Hysteropterum ephialtes Linnavuori, 1971) are erected. The subgenera Acrestia Dlabola, 1980, Montissus Gnezdilov, 2003, and Atticus Gnezdilov, 2003 are upgraded to genera. The subgenus Capititudes Gnezdilov, Drosopoulos et Wilson, 2004 is transferred to the genus Acrestia, and the subgenus Stygiata Emeljanov, 1972 to Celyphoma Emeljanov, 1971. The subtribe Agalmatiina Gnezdilov, 2002 and the subfamily Hysteropterinae Melichar, 1906 are placed in synonymy under Issina Spinola, 1839.

Revision of the carabid genus <Emphasis Type="Italic">Meroctenus</Emphasis> Gemminger et Harold,with a new status of <Emphasis Type="Italic">Xenodochus</Emphasis> Andrewes (Coleoptera,Carabidae: Harpalini)

Originally described as a monotypical genus with unclear taxonomic position from Sudan, Meroctenus Gemminger et Harold, 1868 is treated as a polytypical genus of the Selenophori genus group with two subgenera: Meroctenus s. str. and Xenodochus Andrewes, 1941, stat. n. (the latter was previously considered a distinct genus). Within Meroctenus, two species are recognized: M. (Meroctenus) crenulatus Chaudoir, 1843 (type species) and M. (M.) mediocris (Andrewes, 1936), comb, n., transferred to Meroctenus s. str. from Xenodochus. A new subspecies M. (M.) crenulatus orientalis subsp. n. is described from Pakistan. Diagnoses of the genus Meroctenus in new interpretation as well as of its two subgenera are discussed, and a taxonomic review of the subgenus Meroctenus s. str. with a key to the species and subspecies is provided. The following synonymy is proposed: Meroctenus Gemminger et Harold, 1868 = Paregaploa Müller, 1947, syn. n.; Meroctenus crenulatus (Chaudoir, 1843) = Egaploa (Paregaploa) conviva Müller, 1947, syn. n. Lectotypes are designated for Ctenomerus crenulatus Chaudoir, 1843 and Xenodus mediocris Andrewes, 1936.     

New and little-known crickets of the subfamily phalangopsinae (Orthoptera,Gryllidae): 4. Neotropical genus <Emphasis Type="Italic">Uvaroviella</Emphasis>

The former genera Acla Heb., Aclodes Heb., and Paraclodes Des.-Grand., are considered subgenera of the genus Uvaroviella Chop. Five new subgenera and nine new species of this genus from Ecuador and Guyana are described. Two new species names are proposed due to the secondary homonymy, and one old species name was resurrected from synonymy as a replacement name. Lectotype for U. cavicola Chop. is designated. New data on the geographical and bitopical distribution of some species are given. The paper is based on the material from the collections of the Zoological Institute, Russian Academy of Sciences, St. Petersburg (ZIN), and the Natural History Museum, London (NHM).     

A new subgenus and a new species of the tenebrionid genus <Emphasis Type="Italic">Leptodes</Emphasis> Dejean, 1834 (Coleoptera,Tenebrionidae)

The genus Leptodes was erected by Dejean (1834) for a single species, Sepidium boisduvalii Zubkoff, 1833, which is, consequently, the type species by monotypy. Kaszab (1959) established in Leptodes the subgenus Leptodinopsis based on the same type species, Sepidium boisduvalii. Thus the names Leptodes and Leptodinopsis are objective synonyms: Leptodes Dejean, 1834 = Leptodinopsis Kaszab, 1959, syn. n. A new subgenus Mesoleptodes G. Medvedev et Iljina subgen, n. (type species Leptodes semenowi Reitter, 1892) is established for species which Kaszab included in Leptodes s. str. A new species, Leptodes daghestanicus G. Medvedev et Iljina, sp. n., is described from Daghestan.     

Morphological variation in pollen grains of <Emphasis Type="Italic">Mucuna</Emphasis> (Leguminosae): new biogeographic and evolutionary patterns

Mucuna comprises 105 species with an overall pantropical distribution and is divided into three subgenera: M. subg. Mucuna, M. subg. Stizolobium and M. subg. Macrocarpa. Although phylogenetic studies have supported the occurrence of three main clades, evolutionary relationships among them are not fully resolved. The objective of this study was to examine pollen grain morphology from representatives of all three subgenera and map these onto the phylogenetic trees generated by analysis of other characters. Pollen grain surface, form, size, and aperture number were compared. A Bayesian inference tree using matK sequences was constructed. The results indicate that the representatives of M. subg. Macrocarpa have the smallest pollen grains in the genus (a synapomorphic character here identified for this subgenus) and that species of subgenus Mucuna (those with umbelliform inflorescences) have the largest pollen grains. Additional morphological diversity of the pollen grain surface was noted: reticulate and/or micro-reticulate (in all three subgenera), perforate, gemmate or verrucose (only in M. subg. Mucuna). For all studied taxa, the pollen grains are triaperturate, except for two species of M. subg. Mucuna, which have tetraperturate pollen. The phylogenetic tree obtained using the matK marker resolved M. subg. Stizolobium as the earliest diverging lineage in Mucuna. Based on this phylogeny, a reticulate ornamentation pattern of the pollen surface may represent the ancestral state for the genus, while the larger pollen size and the foraminate, gemmate, and verrucose ornamentations are derived characteristics within the genus. These putative derived ornamentations have been observed only in neotropical species.     

A contribution to the knowledge of the weevils of the subgenus Nubidanus Rtt., allied to Otiorhynchus impexus Schh. (Coleoptera, Curculionidae)

Results of the investigation of the subgenus Nubidanus Rtt. (sensu Reitter) of the genus Otiorhynchus are reported. The impexus species-group of the subgenus Nubidanus comprises 5 species from the Caucasus: O. impexus, O. juvenilis, O. poricollis, O. jarpachlinus, and O. hajastani. Morphological diagnoses and detailed distribution patterns of the species are given. Lectotypes of O. poricollis and O. jarpachlinus are designated. A new synonymy is established: O. poricollis Schoenherr, 1832 = O. breviusculus Stierlin, 1875, syn. n. Variants of the genesis scenario of the impexus species-group in the eastern part of the Caucasus are discussed.     

Phylogeny of the Permian family Metalegoceratidae (Goniatitida,Ammonoidea)

The paper discusses the evolution of the Permian ammonoid family Metalegoceratidae, and a new phylogenetic reconstruction is proposed. Three subfamilies are recognized in this family: Metalegoceratinae Plummer et Scott, 1937; Pericycloceratinae Zhao et Zheng, 1977; and Eothinitinae Ruzhencev, 1956. The genus Metalegoceras Schindewolf, 1931 is subdivided into three subgenera: Metalegoceras s. str., Mesometalegoceras subgen. nov., and Artimetalegoceras subgen. nov. Five species of the endemic South Chinese metalegoceratids are described: Pseudometalegoceras shangraoense (Zhao et Zheng, 1977), P. liratum (Zhao et Zheng, 1977), P. platyventrum (Zhao et Zheng, 1977), P. spirale (Zhao et Zheng, 1977), and Pericycloceras costatum (Zhao et Zheng, 1977).     

Taxonomic position of Afghan vole (Subgenus <Emphasis Type="Italic">Blanfordimys</Emphasis>) by the sequence of the mitochondrial <Emphasis Type="Italic">cytb</Emphasis> gene

It is rather difficult to construct a system of gray voles of the tribe Microtini by a set of morphological and karyological characters because form generation is mosaic at these organization levels. The sequence of the mitochondrial cytochrome b gene was used to study the phylogenetic relationships and taxonomic position of the Central Asian subgenus Blanfordimys. Afghan vole Microtus (Blanfordimys) afghanus and Bucharian vole M. (Blanfordimys) bucharensis clustered with Pamir vole M. (Neodon) juldaschi, which is conventionally assigned to another subgenus. The last two species proved to be significantly closer to each other than either of them was to M. (Blanfordimys) afghanus, which disagrees with the monophyletic origin accepted for Blanfordimys. The genetic distances between the species of the subgenus Blanfordmys and M. juldaschi were comparable with the distances between the sister subgenera Microtus s. str. and Sumeriomys or Pallasiinus and Alexandromys and with the basal divergence of supraspecific clades in the subgenus Terricola. It was assumed that a special Central Asian group of species exists within the tribe Microtini and includes species of the subgenus Blanfordimys and M. juldaschi and that the subgenera Neodon and Blanfordimys should be revised.     

Phylogenetic relationships in Iranian <Emphasis Type="Italic">Scutellaria</Emphasis> (Lamiaceae) based on nuclear ribosomal ITS and chloroplast <Emphasis Type="Italic">trn</Emphasis>L-F DNA data

The genus Scutellaria (Lamiaceae, Scutellarioidae) includes taxa with a wide range of pharmacological traits, which make this genus economically important. Previous taxonomical studies on Scutellaria were mainly based on morphological and chromosomal characters. The infrageneric classification of the genus has been the subject of a long controversy among authors, and delimitation of taxa remains problematic. In this study, the phylogeny of the genus was evaluated using nrDNA ITS and trnL-F sequences, with a focus on the 42 Iranian taxa belonging to subgenera Apeltanthus and Scutellaria. In both ITS and trnL-F trees, there were two main clades within the genus corresponding to the two subgenera Scutellaria and Apeltanthus. In the subg. Scutellaria, the sect. Anaspis was monophyletic, but the monophyly of sect. Scutellaria was not supported. In this subgenus, S. galericulata was located away from other species in both trees, supported the isolation of this species from the sect. Scutellaria and inclusion in the sect. Galericularia as was previously considered by some authors. In subg. Apeltanthus, sect. Apeltanthus and sect. Lupulinaria were not monophyletic; furthermore, the monophyly of subsect. Lupulinaria was not supported. Based on the results of this study, it can be suggested that the sectional classification of both subgenera Apeltanthus and Scutellaria should be revised.     

Chromosomal and molecular studies of cryptic species of the subgenus <Emphasis Type="Italic">Terricola</Emphasis> (Rodentia,Arvicolinae, <Emphasis Type="Italic">Microtus</Emphasis>) in the Caucasian region: Analysis of new records

Using chromosomal and molecular (cytb) markers, the specific identity of 78 individuals of cryptic species of voles of the subgenus Terricola was ascertained. The animal samples were obtained at 13 localities of the Caucasian region, from Krasnodar krai to North Ossetia in the Greater Caucasus and in the Stavropol Upland (forest island in the steppe) in Ciscaucasia, which had not been covered earlier in genetic studies. In the total sample, two chromosomal forms (cryptic species), namely, Microtus (Terricola) majori (2n = 54, NF = 60) and M. (T.) daghestanicus (2n = 54, NF = 58), were identified. The specific identity of most animals tested was confirmed by karyological means, and for individuals from two localities on the south slopes of the Greater Caucasus (Adlerskii district of Krasnodar krai), it was confirmed exclusively by means of molecular (cytb) markers. The last two records were used for evaluation of the differential role of sibling-species of the subgenus Terricola in circulation of the pathogen in mountain loci of hemorrhagic fever with renal syndrome (HFRS) in the Western Caucasus. For the first time, using the example of M. (T.) majori from the Ciscaucasia, which was compared with those of the mountain part of the species’ natural habitat, the role of isolation factors in morphogenesis of the subgenus Terricola was studied. As a whole, the results obtained specify the character of the geographical distribution and biotope attachment of cryptic species of the subgenus Terricola in the Caucasian region.
