Genealogy of the nuclear β-fibrinogen intron 7 in Lissotriton boscai (Caudata, Salamandridae): concordance with mtDNA and implications for phylogeography and speciation
Provedor de dados: Naturalis Digital Academic Repository
Autores: Teixeira, J.; Martínez-Solano, I.; Buckley, D.; Tarroso, P.; García-París, M.; Ferrand, N.
The power of phylogeographic inference resides in its ability to integrate information from multiple sources in an iterative hypothesis-testing framework. In this paper, we build upon previous mtDNA-based hypotheses about the evolutionary history of the Iberian newt Lissotriton boscai using sequences of the highly variable nuclear β-fibrinogen intron 7. In addition to the nuclear sequences, we produced new mtDNA data across the species range to delineate contact zones and test the congruence between nuclear and mitochondrial datasets at the same level of spatial organization. Through a combination of phylogenetic, phylogeographic continuous diffusion, and genetic landscape modelling analyses, we infer the evolutionary history of the species. We found...

An integrated approach to delimiting species borders in the genus Chrysotoxum Meigen, 1803 (Diptera: Syrphidae), with description of two new species
Provedor de dados: Naturalis Digital Academic Repository
Autores: Nedeljković, Z.; Ačanski, J.; Đan, M.; Obreht-Vidaković, D.; Ricarte, A.; Vujić, A.
Integrative taxonomy tests the validity of taxa using methods additional to traditional morphology. The existence of two different morphotypes in specimens identified as Chrysotoxum vernale Loew (Diptera: Syrphidae) prompted their taxonomic study using an integrative approach that included morphology, wing and male-surstylus geometric morphometrics, genetic and ecological analyses. As a result, a new species is recognised, Chrysotoxum montanum Nedeljković &amp; Vujić sp. nov., and C. vernale is re-defined. A lectotype and paralectotypes are designated for C. vernale to stabilize this concept. An additional species, Chrysotoxum orthostylum Vujić sp. nov., with distinctive male genitalia is also described. The three species share an antenna with the...

DNA barcoding, phylogeny and systematics of Golden-backed frogs (Hylarana, Ranidae) of the Western Ghats-Sri Lanka biodiversity hotspot, with the description of seven new species
Provedor de dados: Naturalis Digital Academic Repository
Autores: Biju, S.D.; Garg, S.; Mahony, S.; Wijayathilaka, N.; Senevirathne, G.; Meegaskumbura, M.
A systematic revision of the genus Hylarana in the Western Ghats-Sri Lanka biodiversity hotspot is presented. Species delineation in Hylarana is complicated due to a lack of distinct colour differences or striking morphological characters, leading to potential misidentification. We conducted extensive surveys throughout the Western Ghats-Sri Lanka biodiversity hotspot and performed multiple gene (16S, COI and Cytb) barcoding using 103 samples collected from cultivated land and natural habitats. Genetic distance comparisons and Neighbor Joining trees indicated the presence of at least 14 candidate species in the region, supported by taxa groupings for all three genetic markers. Utilising a combination of molecular and morphological data, we describe seven...

The phylogenetic position of Artematopodidae (Coleoptera: Elateroidea), with description of the first two Eurypogon species from China
Provedor de dados: Naturalis Digital Academic Repository
Autores: Kundrata, R.; Bocakova, M.; Bocak, L.
The Artematopodidae is a species-poor beetle family with contentious relationships to byrrhoid and elateroid families. Recent molecular phylogenetic analyses brought ambiguous results based on a single sequenced species. We investigated the taxonomic placement of Artematopodidae within Elateriformia using ribosomal (18S, 28S) and mitochondrial (rrnL, cox1) molecular markers and three artematopodid species. Our analyses placed Artematopodidae close to Omethidae+Telegeusidae in a basal position of broadly defined Elateroidea. Additionally, we described the first artematopodid species from China – Eurypogon jaechi sp. nov. and E. heishuiensis sp. nov. These species are reported from mountains of Yunnan and can be easily distinguished from their Palaearctic...

Molecular phylogenetics and comparative anatomy of Kimberleytrachia Köhler, 2011 - a genus of land snail endemic to the coastal Kimberley, Western Australia with description of new taxa (Gastropoda, Camaenidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Criscione, F.; Köhler, F.
Kimberleytrachia Köhler, 2011 is a genus of camaenid land snail endemic to the Western Australian Kimberley region. It comprises twelve previously recognised species, all of which occur within the high precipitation zone along the north-western coast between the Admiralty Gulf and King Sound and within less than about 50 km distance from the coast. By evaluating the variation in shell and genital anatomy as well as the differentiation in the mitochondrial markers 16S and COI, we assess the monophyly of Kimberleytrachia with respect to other camaenid genera from north-western Australia. In addition, we newly describe six species (K. jacksonensis n. sp., K. leopardus n. sp., K. nelsonensis n. sp., K. serrata n. sp., K. setosa n. sp. and K. silvaepluvialis n....

Genetics and morphology of the genus Tritetrabdella (Hirudinea, Haemadipsidae) from the mountainous rain forests of Sabah, Borneo, reveal a new species with two new subspecies
Provedor de dados: Naturalis Digital Academic Repository
Autores: Kappes, H.
Blood-feeding terrestrial leeches of the family Haemadipsidae are a notorious part of the invertebrate diversity in Asian and Australian rain forests. All hitherto published records of terrestrial leeches of Borneo belong to the genus Haemadipsa. Here, a second, poorly known haemadipsid genus is reported from Mount Kinabalu and Crocker Range National Park. The individuals were barcoded and compared to sequences available in GenBank. The results show that the genus Tritetrabdella has representatives in the Indochinese and the Sundaic bioregions. All six specimens from Borneo are from a single new Tritetrabdella lineage, T. kinabaluensis spec. nov. Within the Bornean lineage, two groups differing 4-5% in the COI barcoding sequence were identified. Because 1)...

Phalonidia manniana, een complex van twee soorten: Ph. manniana en Ph. udana (Lepidoptera: Tortricidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Groenen, F.; Huisman, K.J.; Doorenweerd, C.
Tijdens het project om van alle Noord-Europese vlinders de DNA-barcode te bepalen, zijn bij Phalonidia manniana, in voornamelijk Scandinavisch materiaal, twee clusters gevonden. Bij verder morfologisch onderzoek zijn constante verschillen gevonden in het uiterlijk en de mannelijke en vrouwelijke genitaliën, die het DNA-onderzoek ondersteunen. Uit kweekresultaten werden vervolgens aanvullende gegevens bekend over een verschillende levenswijze van de twee clusters. Mutanen en collega’s concluderen dat het hier gaat om twee soorten: Ph. manniana en Ph. udana. Beide soorten blijken in Nederland voor te komen. Op basis van onderzoek in enkele collecties hebben we de Nederlandse verspreiding in beeld gebracht. Verder vermelden we enkele interessante buitenlandse...

Explosieve verspreiding van de lindevouwmot: nu ook in Nederland?
Provedor de dados: Naturalis Digital Academic Repository
Autores: Doorenweerd, C.; As, B. van; Scheffers, J.
Een recente vondst van de lindevouwmot (Phyllonorycter issikii) in Zuid-Holland duidt op een sterke uitbreiding van de soort in Nederland, die voorheen alleen uit de omgeving van Roermond bekend was. Dit sluit aan op de Europese verspreidingsgeschiedenis van Ph. issikii, met een gestage uitbreiding vanuit het oosten richting het westen sinds de jaren 1980. De herkenning van de soort, met name van de rupsen en de bladmijnen die zij maken op lindes, wordt besproken en tegelijk wordt er opgeroepen om vondsten te melden. De vraat aan lindes (Tilia) blijft in de meeste gevallen beperkt en zorgt niet voor verkleuring van het blad.

Immature stages and phylogenetic importance of Astrapaeus, a rove beetle genus of puzzling systematic position (Coleoptera, Staphylinidae, Staphylinini)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Pietrykowska-Tudruj, E.; Staniec, B.; Wojas, T.; Alexey, A.
For the first time eggs, larvae and pupae obtained by rearing are described for Astrapaeus, a monotypic West Palearctic rove beetle genus of a puzzling phylogenetic position within the megadiverse tribe Staphylinini. Morphology of the immature stages of Astrapaeus ulmi is compared to that of other members of the tribe and discussed in a phylogenetic context. Contrary to conventional systematics and in accordance with recently developed phylogenetic hypotheses based on morphology of adults, larval morphology supports the non-Quediina affiliation of Astrapaeus. Eggs and pupae provided fewer characters with putative phylogenetic signal. Under laboratory conditions, a peculiar preference for isopod prey was observed for A. ulmi. However, this could not be...

Mitochondrial and morphological differentiation in a previously unrecognized radiation of the land snail genus Parachloritis Ehrmann, 1912 on Timor (Pulmonata: Camaenidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Köhler, F.; Kessner, V.
The present work revises the taxonomy of one group of camaenid gastropods from Timor-Leste based on the study of a large number of recently collected ethanol preserved samples as well as historic museum material, including types. By employing comparative analyses of the variation in morphological features (shell, penial anatomy) and the differentiation in mitochondrial DNA sequences of the cytochrome c oxidase subunit 1 gene (COI) and the 16S rDNA (16S), altogether nineteen species are recognized from Timor-Leste and adjacent areas in the Lesser Sunda and Moluccas, such as West-Timor, Adonara, Leti and Sermata Islands (Indonesia). Four of these species were described previously and have mostly been placed within the genus Chloritis Beck, 1837 in the few...

Morphology and DNA sequence data reveal the presence of Globodera ellingtonae in the Andean region
Provedor de dados: Naturalis Digital Academic Repository
Autores: Lax, P.; Rondan Dueñas, J.C.; Franco-Ponce, J.; Gardenal, C.N.; Doucet, M.E.
Potato cyst nematodes, G. rostochiensis and G. pallida, are the most economically important nematode pests of potatoes worldwide and are subject to strict quarantine regulations in many countries. Globodera ellingtonae was recently described from Oregon (USA), with its host-plant in the field being still unknown. Roots of Andean potatoes from the North of Argentina have been found attacked by this nematode, providing further evidence that this is a potato cyst nematode species, along with G. pallida and G. rostochiensis. New information about morphological, biological and molecular aspects of G. ellingtonae is provided for diagnostic purposes. The Argentine population showed morphological differences from specimens from Oregon; therefore, new diagnostic...

Evolution of species-specific major seminal fluid proteins in placental mammals by gene death and positive selection
Provedor de dados: Naturalis Digital Academic Repository
Autores: Meslin, C.; Laurin, M.; Callebaut, I.; Druart, X.; Monget, P.
The seminal fluid is a complex substance composed of a variety of secreted proteins and has been shown to play an important role in the fertilisation process in mammals and also in Drosophila. Several genes under positive selection have been documented in some rodents and primates. Our study documents this phenomenon in several other mammalian taxa. We study the evolution of genes that encode for 20 proteins that are quantitatively predominant in the seminal fluid of at least one out of seven domestic animal species. We analyse the amino acid composition of these proteins for positive selection and for the presence of pseudogenes. Genes that disappeared through pseudogenisation include KLK2 in cattle, horse and mice. Traces of positive selection are found...

Taxonomic utility of female copulation organs in Sericini chafers (Coleoptera, Scarabaeidae), with special reference to asymmetry
Provedor de dados: Naturalis Digital Academic Repository
Autores: Özgül-Siemund, A.; Ahrens, D.
Female genitalia are widely underrepresented in taxonomic studies. Here we investigate the morphological variation among female copulation organs for a group of scarab beetles (Sericini) with similar ecology, external morphology and copulation mechanics. We examined traits qualitatively and quantitatively based on 80 and 18 species (genus Pleophylla), respectively. Additionally we explored whether female genitalia are affected by asymmetry. The vast diversity of slerotised structures including their shapes illustrated the high taxonomic and phylogenetic utility of female genitalia in this group. The morphometric analysis of Pleophylla, confirmed that sclerotisations in the ductus bursae are very suitable for species-level taxonomic purposes. Stable...

DNA barcoding of the leaf-mining moth subgenus Ectoedemia s. str. (Lepidoptera: Nepticulidae) with COI and EF1-α: two are better than one in recognising cryptic species
Provedor de dados: Naturalis Digital Academic Repository
Autores: Nieukerken, E.J.; Doorenweerd, C.; Stokvis, F.R.; Groenenberg, D.S.J.
We sequenced 665bp of the Cytochrome C Oxidase I (COI) barcoding marker for 257 specimens and 482bp of Elongation Factor 1-α (EF1-α) for 237 specimens belonging to the leafmining subgenus Ectoedemia (Ectoedemia) in the basal Lepidopteran family Nepticulidae. The dataset includes 45 out of 48 West Palearctic Ectoedemia s. str. species and several species from Africa, North America and Asia. Both COI and EF1-α proved reliable as an alternative to conventional species identification for the majority of species and the combination of both markers can aid in species validation. A clear barcode gap is not present, and in some species large K2P intraspecific pairwise differences are found, up to 6.85% in COI and 2.9% in EF1-α. In the Ectoedemia rubivora species...
