<Emphasis Type="Italic">Elaphoglossum mickeliorum</Emphasis> (Dryopteridaceae), a new species of <Emphasis Type="Italic">Elaphoglossum</Emphasis> sect. <Emphasis Type="Italic">Polytrichia</Emphasis> from Peru

Elaphoglossum mickeliorum, a new species from the eastern slopes of the Peruvian Andes, is here described and illustrated. It belongs to E. sect. Polytrichia, which is characterized by the presence of subulate scales and absence of hydathodes on the sterile leaves of adult sporophytes. Herbarium specimens of this new species were first collected by Alwyn H. Gentry ca. 40 years ago, but these got readily confused with E. erinaceum and went undescribed since then. The new species differs from members of the E. erinaceum complex by having a nearly continuous band of planar, nonsubulate scales along the laminar margins of sterile leaves. Based on this character, E. mickeliorum resembles species such as E. glaziovii, E. ornatum, and E. scolopendrifolium. It differs from these by the presence of minute glandular hairs on petioles and costae. A distribution map and a figure with line drawings are also provided. For comparative purposes, the line drawing includes E. blepharoglottis, which is here illustrated for the first time.     

A New Synonym and New Records of South-American Eumastacidae (Caelifera: Orthoptera: Eumastacoidea)

Temnomastax spielmanni Olivier, 2014 n. syn. is proposed as new synonym of Eumastacops nemorivaga Rehn & Rehn, 1942. New distribution records in Peru and Colombia are provided for the following four species: Eumastax nigrovittata Descamps, 1979; Paramastax nigra (Scudder, 1875); Pseudomastax nigroplagiata Descamps, 1970; and Pseudomastax personata (Bolívar, 1881). New information on the distribution of Paramastax flavovittata Descamps, 1973 and E. nemorivaga is added, resulting in the expansion of the geographic distribution. Photographs of all studied species are provided.

New and previously unknown Eurytomidae (Hymenoptera) species from Yemen

Ten new species of the genera Eurytoma (8 species) and Tetramesa (2 species) from Yemen are described (Eurytoma lahji Zerova, E. thoraxica Zerova, E. cyrtophorae Zerova, E. longipes Zerova, E. yemeni Zerova, E. mabari Zerova, E. tibiaspinae Zerova, E. longitarsis Zerova, Tetramesa sanai Zerova, and T. rujumi Zerova). The type specimens of the new species are deposited in the collection of the Institute of Zoology, National Academy of Sciences of Ukraine, Kiev.     

Taxonomic implications of the morphological and genetic variation of cultivated and domesticated populations of the <Emphasis Type="Italic">Agave angustifolia</Emphasis> complex (Agavoideae,Asparagaceae) in Oaxaca,Mexico

The Agave angustifolia complex, distributed from Mexico to Costa Rica, comprises four species and five varieties, including three species used for mescal production. The complex is represented in the Mexican state of Oaxaca by two wild taxa, A. angustifolia var. angustifolia and A. angustifolia var. rubescens, the cultivated form A. angustifolia “Espadín” and the partially cultivated species A. rodacantha. The aims of this study were to investigate the morphological and genetic variation of the A. angustifolia complex in the state of Oaxaca and to identify traits useful for taxonomic delimitation. Four wild and three cultivated populations of A. angustifolia from Oaxaca, one population of A. tequilana from Guanajuato and one population of A. angustifolia from Sonora were sampled for morphological, genetic and cytometric analyses. We showed that cultivated populations of A. angustifolia “Espadin,” A. rhodacantha and A. tequilana could be clearly differentiated from wild populations. Furthermore, the domesticated populations of A. angustifolia, known locally as “Espadin,” had a higher ploidy level and lower genetic variation than their related wild populations. The population of A. angustifolia from Sonora could be recognized as a different entity. Populations of A. rhodacantha need to be studied throughout their entire distribution area to further evaluate their taxonomic delimitation.     

New Agrostis from the California coast

Agrostis clivicola, A. clivicola var.punta-reyesensis andA. blasdalei var.marinensis are described from the California coast. A key distinguishes these from other species of similar habit and habitat.     

Sterigmatomyces,a new fungal genus from marine areas

A new Deuteromycete genus,Sterigmatomyces, is described. Differentiation from non-filamentous yeast-like organisms is based on the formation of conidia on sterigmata. Neither blastospores nor ballistospores are formed. Sexual reproduction has not been observed.S. halophilus sp.n. as the type species and a variety,S. halophilus sp.n. var.indicus var. n., are described.     

Molecular characterisation of four echinostomes (Digenea: Echinostomatidae) from birds in New Zealand,with descriptions of <Emphasis Type="Italic">Echinostoma novaezealandense</Emphasis> n. sp. and <Emphasis Type="Italic">Echinoparyphium poulini</Emphasis> n. sp.

Morphological and molecular characterisation of echinostome specimens (Digenea: Echinostomatidae) recovered in one Anas platyrhynchos L. and one Cygnus atratus (Latham) (Anseriformes: Anatidae) from New Zealand revealed the presence of two known species, Echinostoma miyagawai Ishii, 1932 and Echinoparyphium ellisi (Johnston & Simpson, 1944) and two species new to science. Comparative morphological and phylogenetic analyses supported the distinct species status of Echinostoma novaezealandense n. sp. ex Branta canadensis (L.), A. platyrhynchos and C. atratus, and Echinoparyphium poulini n. sp. ex C. atratus. Echinostoma novaezealandense n. sp., a species of the “revolutum” species complex characterised by the possession of a head collar armed with 37 spines, keyed down to E. revolutum but was distinguished from the latter in having a much narrower body with almost parallel margins, longer oesophagus, wider cirrus-sac, larger seminal vesicle, much smaller ventral sucker, ovary, Mehlis’ gland and testes, more anteriorly located ovary and testes, and distinctly smaller eggs (81–87 × 42–53 vs 106–136 × 55–70 µm). This new species appears similar to Echinostoma acuticauda Nicoll, 1914 described in Australia but differs in having a longer forebody, more posteriorly located ovary and testes, and much smaller eggs (81–87 × 42–53 vs 112–126 × 63–75 µm). Echinoparyphium poulini n. sp. is differentiated from the four species of Echinoparyphium possessing 37 collar spines considered valid as follows: from E. chinensis Ku, Li & Chu, 1964 in having a much smaller body, four (vs five) angle spines and simple seminal vesicle (vs bipartite); from E. schulzi Matevosyan, 1951 in having a less robust body at a comparable body length, much smaller ventral sucker, ovary and testes, and longer but narrower eggs (87–109 × 50–59 vs 70–85 × 60–84 µm); and from the two smaller forms, E. serratum Howell, 1968 and E. aconiatum Dietz, 1909, in a number of additional metrical features correlated with body size and especially in the possession of much larger collar spines. Partial fragments of the mitochondrial nad1 and 28S rRNA genes were amplified for representative isolates of the four species and analysed together with sequences for Echinostoma spp. and Echinoparyphium spp. available on GenBank. Phylogenetic analyses based on the mitochondrial nad1 gene revealed congruence between the molecular data and species identification/delineation based on morphology; this was corroborated by the 28S rDNA sequence data.     

Molecular analyses of <Emphasis Type="Italic">Ficus erecta</Emphasis> and its allies within the subsection <Emphasis Type="Italic">Frutescentiae</Emphasis> (Moraceae)

Ficus (Moraceae) is a keystone group in tropical and subtropical forests with remarkable diversity of species and taxonomical challenges as a consequence of fig–pollinator coevolution. Ficus subsect. Frutescentiae includes about 30 species that are predominantly shrubs or small trees with Terminalia branching. Many of these species are difficult to delimit morphologically, and the group includes a tangle of uncertain taxa and incorrectly applied names. We conducted a phylogenetic analysis with internal and external transcribed spacer data (ITS and ETS) and data from 18 polymorphic microsatellite loci to evaluate the species status of the most perplexing members of this subsection. The results confirm the monophyly of subsect. Frutescentiae, with F. pedunculosa as sister to the rest. The F. erecta complex comprises approximately 17 taxa: F. erecta, F. abelii, F. boninsimae, F. nishimurae, F. iidaiana, F. gasparriniana var. laceratifolia, F. gasparriniana var. viridescens, F. pyriformis, F. stenophylla, F. fusuiensis, F. fengkaiensis, F. sinociliata, F. tannoensis, F. vaccinioides, F. formosana, F. pandurata, and F. periptera. The last five of these were supported as good species, while the others were not well supported by the present evidence. Evidence also supported the status of the non-F. erecta complex species including. F. pedunculosa, F. ischnopoda, F. heteromorpha, and F. variolosa. Ficus filicauda and F. neriifolia are possibly conspecific. The species status of F. potingensis should be restored and it should be treated as a member of section Eriosycea. Identification of the remaining taxa (F. gasparriniana var. esquirolii, F. ruyuanensis, F. daimingshanensis, F. chapaensis, F. changii, F. trivia, and F. tuphapensis) and their relationships to the F. erecta complex were not clarified. As a whole, only ten species in this subsection are confirmed, one is excluded, one is synonymous, and the others are either unresolved or short of samples. There appears to be a consistent genetic background among these unresolved groups, which suggests that repeated hybridization (as a result of pollinator host shifts) has filled up the interspecific gaps during the fig–pollinator coevolution process.     

Centric diatom algae (Centrophyceae) of ultraoligotrophic Lake Elgygytgyn and water bodies of its basin (Chukotka,Russia)

The electron microscopy study of algae from Lake Elgygytgyn and the water bodies of its basin has revealed 21 taxa of centric diatoms of specific and intraspecific ranks. Nine new species and varieties have been found, including Aulacoseira distans var. nivaloides, A. distans var. septentrionalis, Discostella guslyakovyi, which are rare for the flora of Russia; an endemic species (?) Pliocaenicus seckinae; and six interesting forms from the genus Aulacoseira identified only to the genus. The list of Centrophyceae of Beringia has been broadened.     

Genus <Emphasis Type="Italic">Eckhardites</Emphasis> Mitta (Cardioceratidae,Ammonoidea) from the Lower Callovian of the subboreal Jurassic

The genus Eckhardites Mitta 1999, with the type species Macrocephalites pavlowi Smorodina, 1928 is discussed and its diagnosis and assignment to the family Cardioceratidae are substantiated. Eckhardites is compared to the genus Macrocephalites Zittel (family Sphaeroceratidae), to which some workers presently assign the type species of Eckhardites. Three species of Eckhardites are recorded from the basal Callovian elatmae Zone of the Russian Platform, one of which (E. menzeli (Mönnig)) was originally described from the synchronous beds in Germany. A new species E. dietli sp. nov. is described.     

Taxonomy of Senecio multilobatus and its allies

A revision is presented for ten closely related species of western North America. The assemblage approximates the sectionsBolanderiani Greenman andLobati Rydb. Two new infraspecific combinations are made:Senecio bolanderi Gray var.harfordii (Greenman) T. M. Barkley, andS. eurycephalus Torr. & Gray ex Gray var.Iewisrosei (J. T. Howell) T. M. Barkley.     

Revalidation of the Eggvin lumpsucker <Emphasis Type="Italic">Eumicrotremus eggvinii</Emphasis> (Cyclopteridae) and its new finding near Franz Josef Land (Barents Sea)

The species status of a rare species Eumicrotremus eggvinii from the family Cyclopteridae has been revalidated. Some authors considered its specimens as males of close species E. spinosus. In the Zoological Institute collection, males of E. spinosus that are morphologically similar with females of this species have been found. This is evidence of absence of sexual dimorphism in E. spinosus. In new samplings from waters of the Franz Josef Land archipelago (Barents Sea), a specimen of E. eggvinii was found and described. The opinion of some authors that individuals of E. eggvinii represent males of E. spinosus is refuted. A new finding widens the species area to the northeastern limits of the Barents Sea. The number and character of distribution of bone plaques remain reliable taxonomic characters.     

Genetic Diversity in the Worldwide <Emphasis Type="Italic">Botrychium lunaria</Emphasis> (Ophioglossaceae) Complex,with New Species and New Combinations

The Botrychium lunaria (Ophioglossaceae) complex worldwide includes the named species B. lunaria, B. crenulatum, B. tunux, and B. yaaxudakeit. These species have been distinguished from each other morphologically and genetically. This study further investigates the genetic diversity and geographic distribution of this complex, examining a large number of plants worldwide. Enzyme electrophoresis was used to examine allelic variation of 22 loci for 1574 plants of putative B. lunaria, B. crenulatum and B. tunux from North America, Eurasia, and New Zealand, and B. dusenii from the Falkland Islands. Variation in allelic composition assessed by genetic identity and cluster analysis using the programs PopGene and STRUCTURE as well as morphology and geography indicated that the complex is composed of six distinct entities; two of which warrant recognition as new species, B. neolunaria, endemic to North America, and B. nordicum, sister to the B. lunaria complex, from Iceland and Norway; and a new combination, B. lunaria var. melzeri , endemic to Greenland, Iceland, and Norway. The new taxa are described in this paper. Three entities within B. tunux are discussed but not proposed for recognition at this time. Botrychium lanceolatum, included in this study, is composed of three morphologically and genetically distinct entities warranting taxonomic recognition.     

New and little known species of the dance-fly subgenus <Emphasis Type="Italic">Xanthempis</Emphasis> Bezzi,genus <Emphasis Type="Italic">Empis</Emphasis> L. (Diptera,Empididae), from the Caucasus

Five new species of the subgenus Xanthempis Bezzi are described from the Caucasus: Empis (Xanthempis) annae sp. n. (Russia: Krasnodar Territory), E. (X.) grichanovi sp. n. (Russia: Krasnodar Territory; Georgia), E. (X.) pseudoconcolor sp. n. (Russia: Krasnodar and Stavropol territories; Georgia: Abkhazia), E. (X.) teberdaensis sp. n. (Russia: Karachay-Cherkessia), and E. (X.) zamotajlovi sp. n. (Russia: Krasnodar Territory and Adygea). The females of E. (X.) alanica Shamshev and E. (X.) kovalevi Shamshev are described for the first time. New data on the distribution of some previously described species are reported. The geographical distribution of Xanthempis is discussed. A key to Xanthempis species from the Caucasus is compiled.     

Revision of the shield-bug genera <Emphasis Type="Italic">Holcostethus</Emphasis> Fieber and <Emphasis Type="Italic">Peribalus</Emphasis> Mulsant et Rey (Heteroptera,Pentatomidae) of the Palaearctic Region

A complex of the heteropteran genera centering around Peribalus Mulsant et Rey and Holcostethus Fieber is considered. The genus Dryadocoris Kirkaldy reveals no relationship with the above genera and is believed to represent a separate clade of the family Pentatomidae. The genera Peribalus and Holcostethus are revised. The former includes three subgenera: Peribalus s. str. with two species, Asioperibalus subgen. n. (type species Cimex inclusus Dohrn) with six species, and Tianocoris subgen. n. (type species Holcostethus manifestus Kiritshenko) with two species. Holcostethus embraces two subgenera: Holcostethus s. str. and the monotypic Enigmocoris subgen. n. (type species H. fissiceps Horváth). Two new species are described: Peribalus tianshanicus sp. n. from the Tien Shan Mts. and P. przewalskii sp. n. from the northern part of China (Huan He River). P. capitatus Jakovlev and P. vernalis (Wolff) are downgraded to subspecies of P. strictus (F.). P. ovatus Jakovlev is synonymized with P. inclusus (Dohrn). Two new monotypic genera related to the revised complex of genera are established, Paraholcostethus gen. n. (type species Peribalus breviceps Horváth) and Himalayastethus gen. n. (type species H. pilosus sp. n. from Kashmir). A key to, and morphometric characters for all the taxa considered are provided. The key characters, including both male and female genitalia, are illustrated, and distributional maps are given.
