Taxonomic status of Amebachia Uchida in the genus Netelia Gray (Hymenoptera; Ichneumonidae; Tryphoninae) with descriptions of four new species from Japan

The lectotype of Amebachia baibarana Uchida, 1928, which is the type species of Amebachia Uchida, was re‐examined. Though this species was synonymized with Netelia (Netelia) laevis (= Paniscus laevis Cameron, 1905) and Amebachia has been synonymized under the subgenus Netelia of the genus Netelia, it is concluded that A. baibarana is a distinct species from N. laevis and Amebachia should be a subgenus of the genus Netelia. Netelia laevis is transferred from the subgenus Netelia to Apatagium. Four new species of Netelia (Amebachia), N. (A.) yoshimatsui sp. nov., N. (A.) rasilella sp. nov., N. (A.) fulvistigma sp. nov., and N. (A.) vicinalis sp. nov. are described from Japan, and a key to the species of this subgenus is provided.     

Two new species of the Empis (Leptempis) rustica group of the Mediterranean basin (Diptera: Empididae: Empidinae)

Two new species of the Empis (Leptempis) rustica group are described: E. (L.) tenuis n. sp. and E. (L.) lauriauti n. sp. Both were mainly collected in mountainous areas of the Mediterranean basin; the first species was collected in Morocco and Southern Spain; the latter was found in late summer in the Southern Alps in France. The key to species of the Empis (L.) rustica group is updated to include these two new species as well as a recently described Caucasian species.     

Subterranean species of the ant genus Crematogaster in Asia (Hymenoptera: Formicidae)

Three Crematogaster ant species, C. (Orthocrema) javanica Menozzi, C. (O.) myops Forel and C. (O.) masukoi sp. nov., share reduced compound eyes which characterizes them among Asian species of the subgenus Orthocrema. The new species is described based on material from Borneo. It can be distinguished from C. javanica and C. myops by its smooth surface of clypeus and acutely produced subpetiolar process. Reduced compound eyes and yellowish body suggest that these three species are subterranean.     

The subgenus Ashima (Diptera,Drosophildae, Phortica) from China,with DNA barcoding and descriptions of three new species

In the present study, three new species found in Yunnan, Southwest China were described as members of the subgenus Phortica (Ashima): P. (A.) haba An & Chen, sp. nov., P. (A.) montipagana An & Chen, sp. nov. and P. (A.) qingsongi An & Chen, sp. nov. Barcode sequences (partial sequences of the mitochondrial COI gene) were collected from 61 specimens of 16 known and the above-mentioned three new Ashima species. The intra- and interspecific pairwise K-2P (Kimura two-parameter) COI distances were analysed and a phylogenetic tree was constructed based on the barcode sequences. Species delimitation in this subgenus was supported by integrating barcodes with morphological information, in particular for the three new species, considered to be cryptic species. In addition, the diversification of lineages in the subgenus Ashima was proposed to occur in southern China and adjacent areas, suggesting specific adaptation of Ashima species to the high plateau environments.

Life history stages and taxonomy of Austrosimulium (Austrosimulium) tillyardianum (Diptera: Simuliidae)

The male, female, pupa, 9th‐instar larva, and egg of Austrosimulium (Austrosimulium) tillyardianum Dumbleton, 1973, are redescribed, and larval instars one to eight are described and morphologically differentiated for the first time. The relationship of A. (A.) tillyardianum to other New Zealand species is briefly reviewed.     

Taxonomic review of the genus Lymantria (Lepidoptera: Erebidae: Lymantriinae) in Korea

A taxonomic review of the Korean Lymantria Hübner, 1819 was conducted. A total of nine species of five subgenera with two unrecorded species are listed: Lymantria (Porthetria) dispar Linnaeus 1758, L. (P.) xylina Swinhoe 1903, L. (Lymantria) monacha (Linnaeus 1758), L. (L.) minomonis Matsumura 1933 (new to Korea), L. (L.) similis monachoides Schintlimeister 2004 (new to Korea), L. (L.) lucescens (Butler 1881), L. (Nyctria) mathura Moore 1865, L. (Collentria) fumida Butler 1877, and L. (Spinotria) bantaizana Matsumura 1933. Lymantria (Lymantria) minomonis and L. (L.) similis monachoides are newly added to the Korean fauna. Lymantria (L.) minomonis was found only on Bogildo Island of Jeollanam‐do in the southern part of Korea, and L. (L.) similis monachoides was collected in central Korea. Lymantria (Porthetria) xylina and L. (Collentria) fumida were not examined in this study, and it is considered that the previous records were due to misidentification or they are only distributed in the northern part of the Korean Peninsula. We provide diagnoses of two unrecorded species and adult habitus and genitalia photos of the Korean Lymantria species.     

Confirmation of neutral buoyancy in <Emphasis Type="Italic">Aethotaxis mitopteryx</Emphasis> DeWitt (Notothenioidei: Nototheniidae)

Aethotaxis mitopteryx is a nototheniid species with a circum-Antarctic distribution in the Southern Ocean. We present new locality records, buoyancy measurements, and morphometric data on five A. mitopteryx specimens collected from the Bransfield Strait. Our analyses demonstrate that A. mitopteryx is neutrally buoyant. This result lends additional support to the hypothesis that neutral buoyancy has a single evolutionary origin in Notothenioidei. Food items in these specimens consisted entirely of krill (Euphausia sp.), and all specimens were sexually immature. We present morphometric data from these five specimens and compare to the holotype specimen, which is the only A. mitopteryx specimen collected in the Ross Sea.     

Neoechinorhynchus (Neoechinorhynchus) chimalapasensis n. sp. (Acanthocephala: Neoechinorhynchidae) from the freshwater fish Awaous banana (Valenciennes) (Gobiidae) in Mexico

Neoechinorhynchus (Neoechinorhynchus) chimalapasensis n. sp. (Eoacanthocephala: Neoechinorhynchidae) is described from the intestine of Awaous banana (Valenciennes) (Pisces: Gobiidae) collected in the Río Negro, a tributary in the upper Río Coatzacoalcos basin, Santa María Chimalapa, Oaxaca State, Mexico. It is the third species of Neoechinorhynchus Stiles & Hassall, 1905 described from Mexican freshwater fishes, although 36 other species are known from freshwater fishes in the Americas. Like four other species of Neoechinorhynchus from freshwater fishes in North America and Mexico, N. (N.) limi Muzzall & Buckner, 1982, (N.) rutili (Müller, 1780) Stiles & Hassall, 1905, N. (N.) salmonis Ching, 1984 and N. (N.) roseus Salgado-Maldonado, 1978, males and females of the new species are less than 20 mm in length, lack conspicuous sexual dimorphism in size, have a small proboscis of about 0.1 mm in length with the largest hooks being the anteriormost, about 30–90 μm in length and of equal size, and have subequal lemnisci, larger than the proboscis receptacle but still relatively short and, in males, generally restricted to a position considerably anterior to the testes. The new species is closest to N. (N.) roseus, but it is distinguished from it by having: (1) a slightly larger cylindrical proboscis with almost parallel sides versus a globular proboscis with a rounded tip which is shorter and somewhat wider in N. (N.) roseus; (2) smaller but robust anterior proboscis hooks that do not reach the equatorial level or extend beyond the hooks of the middle circle as in N. (N.) roseus; and (3) the female gonopore situated ventrally subterminal, as opposed to being a significant distance anteriorly to the posterior extremity in N. (N.) roseus.     

The genus Hyalomma. VI. Systematics of H. (Euhyalomma) truncatum and the closely related species, H. (E.) albiparmatum and H. (E.) nitidum (Acari: Ixodidae)

The geographic distribution of three closely related Hyalomma species, namely Hyalomma (Euhyalomma) truncatum Koch, 1844, Hyalomma (Euhyalomma) albiparmatum Schulze, 1919 and Hyalomma (Euhyalomma) nitidum Schulze, 1919 is confined to Africa. A detailed comparison of all stages of development of the three taxa reveals that they possess many more shared than distinguishing characters. In fact differentiation between these species is based on single or dual qualitative characters on their adults. These are a conspicuous, ivory-coloured parma on H. (E.) albiparmatum males, and the absence or reduction in clarity of ivory-coloured bands on the leg segments of H. (E.) nitidum adults, as well as the shape of the external cuticular preatrial fold of the genital operculum of females of the latter species. The adults of all three species and the larva of H. (E.) truncatum are redescribed. The nymph of H. truncatum and the larva and nymph of H. (E.) albiparmatum and H. (E.) nitidum are described for the first time. Data on their geographic distributions and hosts are provided.     

Banding patterns and chromosomal evolution in five species of neotropical Teiinae lizards (Squamata: Teiidae)

Karyotypes of five species of South American teiid lizards from subfamily Teiinae: Ameiva ameiva, Kentropyx calcarata, K. paulensis, K. vanzoi (2n = 50, all acrocentric), and Cnemidophorus ocellifer (2n = 50, all biarmed), are herein described and compared on the basis of conventional and silver staining, and CBG and RBG banding patterns. Meiotic data are also included. Karyotypes of K. paulensis, K. vanzoi, and C. ocellifer are reported here for the first time. Inter-generic variability in Ag-NORs location was detected with NORs occurring at the end of long arm of pair 1 in K. calcarata, K. paulensis, and K. vanzoi; pair 5 in C. ocellifer and pair 7 in A. ameiva. The location of NORs, along with the karyological differences between A. ameiva and the Central American species (A. auberi), corroboretes the molecular-based hypothesis that the genus Ameiva is paraphyletic. Inter-populational heteromorphism in Ag-NORs size was detected between populations of C. ocellifer. RBG and CBG banding data demonstrated that the biarmed condition of the C. ocellifer chromosomes is due to multiple pericentric inversion events instead of addition of constitutive heterochromatin. Differential-staining techniques used here revealed valuable information about Teiinae karyotypic diversity and made it possible to compare these species, contributing to both the better comprehension of their chromosomal evolution and issues on taxa systematics.     

Specificity of Chroomonas (Cryptophyceae) as a source of kleptochloroplast for Nusuttodinium aeruginosum (Dinophyceae)

The unarmoured dinoflagellate Nusuttodinium aeruginosum retains a kleptochloroplast, which is a transient chloroplast stolen from members of the cryptomonad genus, Chroomonas. Both N. aeruginosum and the closely related N. acidotum have been shown to restrict their diet to a limited number of species of this blue‐green genus of cryptophyte. However, it is still unclear how flexible the predators are with regard to the ingestion and utilization of Chroomonas spp. as a source of kleptochloroplast. To address specificity of cryptomonad in N. aeruginosum, we collected the cells of N. aeruginosum from several ponds in Japan, and analysed the phylogeny of the kleptochloroplasts based on their plastidial 16S rDNA sequences. All sequences obtained in this study were restricted to only one (the subclade 4) of four subclades known to comprise the Chroomonas/Hemiselmis clade. Therefore, N. aeruginosum is specific in its dietary requirements, selecting their prey within the subclade level.     

Detecting cryptic species in sympatry and allopatry: analysis of hidden diversity in Polyommatus (Agrodiaetus) butterflies (Lepidoptera: Lycaenidae)

Modern multilocus molecular techniques are a powerful tool in the detection and analysis of cryptic taxa. However, its shortcoming is that with allopatric populations it reveals phylogenetic lineages, not biological species. The increasing power of coalescent multilocus analysis leads to the situation in which nearly every geographically isolated or semi‐isolated population can be identified as a lineage and therefore raised to species rank. It leads to artificial taxonomic inflation and as a consequence creates an unnecessary burden on the conservation of biodiversity. To solve this problem, we suggest combining modern lineage delimitation techniques with the biological species concept. We discuss several explicit principles on how genetic markers can be used to detect cryptic entities that have properties of biological species (i.e. of actually or potentially reproductively isolated taxa). Using these principles we rearranged the taxonomy of the butterfly species close to Polyommatus (Agrodiaetus) ripartii. The subgenus Agrodiaetus is a model system in evolutionary research, but its taxonomy is poorly elaborated because, as a rule, most of its species are morphologically poorly differentiated. The taxon P. (A.) valiabadi has been supposed to be one of the few exceptions from this rule due to its accurately distinguishable wing pattern. We discovered that in fact traditionally recognized P. valiabadi is a triplet of cryptic species, strongly differentiated by their karyotypes and mitochondrial haplotypes.     

The Tipulidae (Diptera) of northern Morocco with a focus on the Rif region,including the description of a new species of Tipula (Lunatipula) and an updated checklist for Morocco

An overview of the Tipulidae known to occur in northern Morocco with an emphasis on the Rif mountains is given, incorporating new distribution data based on recently collected material in the area. Dolichopeza (Dolichopeza) hispanica, Tipula (Lunatipula) subpustulata, and Tipula (Yamatotipula) afriberia afriberia are recorded for the first time for the Rif. Tipula (L.) stimulosa Mannheims, 1973 and T. (Vestiplex) vaillanti vaillanti Theowald, 1977 are reported for the first time for the Rif and Morocco. Tipula (Lunatipula) pseudocinerascens Strobl, 1906 and Tipula (Savtshenkia) confusa van der Wulp, 1883 are recorded for the first time for the Rif, Morocco and North Africa. A new species of the subgenus Lunatipula, T. (L.) pjotri n. sp., is described and illustrated. Nephrotoma exastigma, previously reported for the Rif, seems to be absent in Morocco. Reports of Tipula (Emodotipula) obscuriventris Strobl, 1900 for Morocco actually refer to T. (E.) leo. This brings the number of Tipulidae for Morocco to 39 species and for the Rif to 28. An updated checklist of the Tipulidae of Morocco is provided.     

Review of the genus Eusterinx Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) with descriptions of five new species from South Korea

South Korean species of the genus Eusterinx Förster are reviewed here. Nine species of the genus Eusterinx are found to occur in South Korea, and five species, Eusterinx (E.) elongata sp. nov. , E. (Holomeristus) hirtis sp. nov. , E. (Ischyracis) fulvipes sp. nov. , E. (I.) petiolata sp. nov. and E. (I.) rufithorax sp. nov. , are described. Four more species of Eusterinx from subgenera Divinatrix, Eusterinx and Holomeristus are recorded from South Korea for the first time. Hitherto, unknown male of the Eastern Palaearctic species E. (Divinatrix) kurilensis Humala is described. A key to all known species of the genus Eusterinx occurring in South Korea is provided.     

Comparisons of recruitment, survival, and growth in invasive and native saplings on a volcano

We monitored the recruitment, survival, and growth of tree saplings on invasive (Larix kaempferi) versus native species (Betula and Populus) using 16 20 m × 20 m plots established along elevation gradient on the volcano Mount Koma, Japan, for 7 years because the sapling behaviors should determine forest structures. The crowding of overstory consists mostly of Larix decreased with increasing elevation. Larix recruits were conspicuous, particularly at middle elevation where overstory crowding was intermediate, while Betula recruits were least. Larix overstory crowding inhibited the recruitment of all the taxa, although intermediate crowding promoted the recruitment of Larix. The restriction of sapling emergence was conspicuous at lower elevation where the overstory crowding was highest, probably because of shading, and/or competition with overstory trees. Sapling recruitment for all taxa was restricted at higher elevation, due to high stresses derived from direct solar radiation and strong wind without overstory. The survival of saplings was 96% for Larix and Betula, while it was ca. 50% for Populus. Larix overstory decreased the survival and growth of all the taxa, except Larix survival and Betula growth. The results implied that Larix could establish by high survival once the recruits succeeded everywhere and native sapling regeneration was restricted by Larix overstory. Strong recruitment, survival, and growth of Larix, together with resistance to overstory crowding, enables it to dominate and persist in such disturbed areas regardless of the canopy closure.     

Hybridization and introgression among three Aconitum (Ranunculaceae) species of different ploidy levels in the Tatra Mountains (Western Carpathians)

Hybridization among species of A conitum effects their morphology and ecology. In this study the hybridization between the diploid 2n(2x) = 16 ( A . lasiocarpum and A . variegatum) and tetraploid 2n(4x) = 32 ( A . firmum) species was documented in the Tatra Mountains (Western Carpathians) in a small, local population in a semi‐natural site. The hybrid species were: homoploid A . × pawlowskii ( A . lasiocarpum × A . variegatum), and triploid A . × berdaui ( A . firmum × A . variegatum, 2n(3x) = 24). Chloroplast DNA (cpDNA) alleles formed two distinct haplotypes, one typical for the tetraploid and another for diploid lines, shared between the tetraploid, triploid and diploid groups, indicating introgressive hybridization. The presumed gene flow was from the tetraploid to diploid species via the triploid bridge. The only two specimens of A . × pawlowskii that harbored tetraploid ( A . firmum) type cpDNA possessed bracteoles of A . firmum‐type. The remaining introgressed (cpDNA and Inter Simple Sequence Repeats (ISSR)) specimens ( A . variegatum) were morphologically pure, implying cryptic introgression. ISSR loci shared between the tetraploid A . firmum and diploid A . variegatum support the hypothesis of an ancient allopolyploid origin of A . firmum and the diploid species of A . variegatum‐type as one of its parent.     

First fungus gnats of genus Manota Williston (Diptera: Mycetophilidae) from Japan

The genus Manota is recorded from Japan for the first time. Three new species, Manota satoyamanis, Manota indahae and Manota tunoae spp. nov., are described, based on specimens collected in an ecological sampling program of arthropods in the “satoyama” landscape of Ishikawa Prefecture. “Satoyama” represents the traditional rural landscape of Japan, which is characterized by a mosaic of secondary forests, plantations, ponds and rice paddy fields. The new species raise the number of Palearctic Manota species from five to eight.     

Seed image analysis and taxonomy of Diplotaxis DC. (Brassicaceae,Brassiceae)

West European Rock lizards, Lacerta (Iberolacerta) have small widely separated ranges in highland areas. Mitochondrial and nuclear DNA sequences corroborate the monophyly of the group and show it is not closely related to any of the other Rock lizards with which it was formerly placed in Archaeolacerta, an assemblage for which there is no evidence of clade status. L. (Iberolacerta) consists of four main units: L. (I.) horvathi of NW Croatia and neighbouring regions; the Pyrenees species, L. (I.) bonnali, L. (I.) aranica and L. (I.) aurelioi; L. (I.) cyreni of the Iberian Sistema Central, with distinctive populations in the Sierras de Bejar, Gredos and Guadarrama; and L. (I.) monticola of the Serra da Estrela of Central Portugal and NW Spain, this unit also contains L. (I.) cyrenimartinezricai of La Peña de Francia, W. Spain and a distinctive population in the Montañas de Sanabria. L. (Iberolacerta) has persisted in some mountain ranges for at least 4.2 ± 1.4 Ma and may have been restricted to mountains by competition from Wall lizards (Podarcis). Its clade status shows it has lost range extensively and has produced few external branches since its initial fragmentation. In contrast, Podarcis diversified about the time L. (Iberolacerta) fragmented, producing a series of widespread lineages that have persisted until the present time. The mainly European subfamily Lacertinae, to which both L. (Iberolacerta) and Podarcis belong, diversified rapidly 13–9 Ma ago, probably largely replacing other lacertid lizards of earlier origin. As another round of replacement started at approximately 9 Ma ago with the spread of Podarcis, this may be a recurrent phenomenon in the evolution of some lizard communities.     

Species delineation in the Capitella species complex (Annelida: Capitellidae): geographic and genetic variation in the northern Gulf of Mexico

Capitella capitata was traditionally used as a biological indicator species due to its ubiquitous distribution and high densities in disturbed and polluted marine and estuarine sediments. Based on allozyme and developmental studies, it is now clear that C. capitata is a species complex consisting of multiple distinct lineages worldwide, including the recently described C. teleta, a model species for spiralian development. The coast of the northern Gulf of Mexico, with its numerous bays and estuaries and frequently occurring natural and anthropogenic disturbances, provides an appropriate region for such studies. We sequenced a fragment of the mitochondrial cytochrome c oxidase subunit I gene for individuals of C. cf. capitata and C. cf. aciculata (distinguished by acicular spines on the first two chaetigers) collected from Texas and Florida coasts and analyzed them in conjunction with data available in GenBank. Our results indicate the presence of a Gulf of Mexico clade that is distinct from populations in Canada and the Indo‐Pacific. Populations in the northern Gulf of Mexico are structured geographically, with support for Texas and Florida clades, and there do not seem to be clear boundaries between C. cf. capitata and C. cf. aciculata. This is corroborated by the fact that multiple specimens were morphologically intermediate between the two species. In future studies, we aim to clarify whether the intermediate morphologies represent ontogenetic stages, neutral morphological variation, phenotypic plasticity, or sexual dimorphism in a single species or whether several lineages with incomplete reproductive barriers are present.
