Molecular systematics and phylogeny of the ‘Marbled Whites' (Lepidoptera: Nymphalidae,Satyrinae, Melanargia Meigen)

Abstract. We investigated genetic divergence and phylogenetic relationships amongst all known species of Palaearctic butterflies of the genus Melanargia using sequence information from three genes [mitochondrial cox1 barcode region (658 bp), ribosomal 16S rRNA (c. 518 bp), and nuclear wg (404 bp)]. Results show a lack of DNA divergence among several poorly characterized taxa, as well as deep divergences within and between others. We corroborated the molecular information with morphological and genitalic characters as well as with geographic data. We revise the taxonomy of Melanargia, and propose a new systematic scheme for the group. We revive some previous synonymies (M. lucasi meadwaldoi stat. rev. , M. ines fathme stat. rev. , M. ines jahandiezi stat. rev. , M. meridionalis tapaishanensis stat. rev. ), revise the status of some subspecies into species (M. transcaspica stat. nov. , M. lucida stat. nov. , M. wiskotti stat. nov. ) and of several species into subspecies of other taxa (M. evartianae sadjadii stat. nov. , M. larissa hylata stat. nov. , M. larissa grumi stat. nov. , M. larissa syriaca stat. nov. , M. larissa titea stat. nov. , M. lugens montana stat. nov. , M. epimede ganymedes stat. nov. ), revise the status of subspecies and transfer them to other species (M. larissa lorestanensis stat. nov. , M. larissa iranica stat. nov. , M. larissa karabagi stat. rev. , M. larissa kocaki stat. nov. , M. transcaspica eberti stat. nov. ), and propose new synonymies (M. larissa titea = M. titea standfussi syn. nov. = M. titea titania syn. nov. , M. leda leda = M. leda yunnana syn. nov. , M. lugens lugens = M. lugens ahyoui syn. nov. , M. lugens hengshanensis = M. lugens hoenei syn. nov. , M. halimede halimede = M. halimede gratiani syn. nov. , M. asiatica asiatica = M. asiatica dejeani syn. nov. , = M. asiatica elisa syn. nov. , = M. asiatica sigberti syn. nov. ).

Integrative taxonomy of the stalk-eyed bug genus Chauliops (Heteroptera: Malcidae: Chauliopinae) reveals orogeny-driven speciation

Economically significant bean pests of the genus Chauliops are species rich in the areas surrounding the Qinghai–Tibet Plateau and provide an excellent system for speciation studies. Here, an integrative taxonomic approach, employing morphological analyses, population genetic methods, and multiple molecular species delimitation methods, was used to clarify the taxonomy of Chauliops in East and Southeast Asia. Four new species (Chauliops parahorizontalis Li & Bu, sp. nov., Chauliops albida Li & Bu, sp. nov., Chauliops bicoloripes Li & Bu, sp. nov., and Chauliops paraconica Li & Bu, sp. nov.) were described, which increases the number of Chauliops species in this area from six to 10; a key for Chauliops species is also provided. Phylogenetic analysis and divergence time estimation revealed that Chauliops was divided into four clades: Clade A (Chauliops bisontula + [Chauliops horizontalis + C. parahorizontalis sp. nov.]), Clade B (C. albida sp. nov. and C. bicoloripes sp. nov.), Clade C (Chauliops quaternaria and Chauliops zhengi), and Clade D (Chauliops fallax + [Chauliops conica + C. paraconica sp. nov.]). Two species diversification events of Chauliops estimated to have occurred 7–1 million years ago (Ma) and 25–13 Ma were detected. These speciation events were consistent with the two historical uplift events of the Qinghai–Tibet Plateau, suggesting that orogeny might have provided opportunities for the diversification of Chauliops species on the southeastern margin of the Qinghai–Tibet Plateau. Our findings show that population genetic analyses can be used to delimit related species and that orogeny is a key driver of species diversification on the southeastern margin of the Qinghai–Tibet Plateau.     

Stenotaenia Koch, 1847: a hitherto unrecognized lineage of western Palaearctic centipedes with unusual diversity in body size and segment number (Chilopoda: Geophilidae)

Based on morphological evidence, we newly define the genus Stenotaenia Koch, 1847 (=Scnipaeus Bergsøe & Meinert, 1866; =Simophilus Silvestri, 1896; =Onychopodogaster Verhoeff, 1902; =Insigniporus Attems, 1903; =Notadenophilus Verhoeff, 1928; =Bithyniphilus Verhoeff, 1941; =Schizopleres Folkmanova, 1956; =Euronesogeophilus Matic, 1972; all syn. nov. ) as including the following 15 species: Stenotaenia linearis (Koch, 1835) (=Geophilus simplex Gervais, 1835; =Geophilus brevicornis Koch, 1837; =Scnipaeus foveolatus Bergsøe & Meinert, 1866; =Himantarium caldarium Meinert, 1886 syn. nov. ; =Geophilus (Geophilus) linearis var. polyporus Verhoeff, 1896 syn. nov. ; =Geophilus ormanyensis Attems, 1903 syn. nov. , after lectotype designation; =Insigniporus acuneli C?pu?e, 1968 syn. nov. ) from central and northern Europe; Stenotaenia frenum (Meinert, 1870) from northern Africa; Stenotaenia romana (Silvestri, 1895) (=Geophilus silvestrii Verhoeff, 1928 syn. nov. ) and Stenotaenia sorrentina (Attems, 1903) (=Geophilus forficularius Fanzago, 1881 syn. nov. ; =Geophilus linearis abbreviatus Verhoeff, 1925 syn. nov. ) from the Italian peninsula and Sardinia; Stenotaenia antecribellata (Verhoeff, 1898) (=Simophilus albanensis Attems, 1929 syn. nov. ), Stenotaenia cribelliger (Verhoeff, 1898), Stenotaenia palpiger (Attems, 1903), Stenotaenia rhodopensis (Kaczmarek, 1970), and Stenotaenia sturanyi (Attems, 1903) from the Balkan peninsula; Stenotaenia naxia (Verhoeff, 1901) (=Geophilus graecus Verhoeff, 1902) from the Aegean islands; Stenotaenia asiaeminoris (Verhoeff, 1898) and Stenotaenia bosporana (Verhoeff, 1941) from Anatolia; Stenotaenia giljarovi (Folkmanova, 1956) from western Caucasus; Stenotaenia fimbriata (Verhoeff, 1934) and Stenotaenia palaestina (Verhoeff, 1925) from Palestine; with the only exception of S. linearis, all of these binomens are comb. nov. In Stenotaenia, a strongly conserved overall morphology is matched by an unusual interspecific variation in both the body size of fully grown specimens (from 1.7 cm in S. romana to 7.7 cm in S. sturanyi) and the number of leg‐bearing segments (from 43 in male S. romana to 115 in female S. sturanyi). The number of segments correlates with maximum body size. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 153 , 253–286.     

Phylogenetic reassessment and biogeography of the Ectateus generic group (Coleoptera: Tenebrionidae: Platynotina)

Owing to the reinterpretation of its morphological synapomorphies, the taxonomic composition of the Ectateus generic group had been ambiguous. The present study scrutinized all existing taxonomic concepts of the group based on a cladistic analysis of the adult morphology of all of the Afrotropical platynotoid Platynotina genera. The phylogenetic relationships were reconstructed using parsimony and Bayesian inference. The results show that all previous taxonomic concepts of the Ectateus generic group concerned paraphyletic entities. The cladistic analysis revealed the following synapomorphies for the taxon: (1) presence of basal indentations of the pronotal disc, (2) ratio of prothorax width to its maximal height > 6.0, and (3) ratio of maximal height of the prothorax to total height < 0.3. Moreover, phylogenetic studies revealed the existence of the Upembarus generic group, a sister‐taxon group to the Ectateus generic group, within the Afrotropical platynotoid Platynotina. Autapomorphic and synapomorphic character mapping show that several taxonomic and nomenclatural changes are needed to consider the particular generic‐level entities traditionally assigned to Afrotropical platynotoid Platynotina as monophyletic lineages. The following taxonomic and nomenclatural adjustments are made in this paper: P teroselinus gen. nov. is erected to accommodate a single species that was previously assigned to Zidalus: Pteroselinus insularis comb. nov. Additionally, the following synonymies are proposed: Anchophthalmops (= Platykochius syn. nov. ), Angolositus (= Aberlencus syn. nov. , = Platymedvedevia syn. nov. ), Glyptopteryx (= Microselinus syn. nov. , = Quadrideres syn. nov. , = Synquadrideres syn. nov. ). In addition, Kochogaster is lowered in rank and is treated as one of the subgenera of Anchophthalmus. Moreover, Pseudoselinus is treated as a subgenus of Upembarus. An identification key to all Afrotropical platynotoid Platynotina genera and subgenera is presented. Zoogeographical analyses revealed the following dispersal barriers for the Ectateus generic group: (1) the Sahara (northern barrier); (2) the dry ecosystems of Botswana, Namibia, and South Africa (southern barrier); and (3) the Congolian rainforests (internal distributional gap). The ancestor of the taxon probably originated in East African ecoregions that predominantly contained wattletrees (acacias) and Commiphora Jacq. Moreover, past climate changes seem to have had a great impact on the observed generic distribution. © 2015 The Linnean Society of London

(72) Kymatocalyx stoloniferus Herz. 1950, syn.nov.: Solenostoma apertum Schiffn. & S. Arn. 1964. Because of the structure of its seta Kymatocalyx Herz. is newly placed within Cephaloziellaceae. (73) Lophozia capitata (Hook.) Boulay 1904 has to replace L. capitata (Hook.) K. Müll. 1950. (74) All Scandinavian records of Lophozia latifolia Schust. are rejected. (75) Notoscyphus macroscyphus Schiffn., N. fluviorum Schiffn. and N. paulensis Schiffn., all in Schiffner & S. Arnell (1964), are newly placed in synonymy of Lophocolea aquatica Herz. 1950. Notoscyphus Mitt s.str. remains palaeotropic in distribution. (76) Plagiochila corniculata (Dum.) Dum. validly dating as a species from 1831 has to replace P. tridenticulata Dum. validly dating as a species from 1835. (77) P. Punctata Tayl. 1846, syn.nov.: P. pitardii Steph. 1921.(78) P. spinulosa (Dicks. 1790) Dum., syn.nov.: P. maderensis Gottsche in Steph. 1904, and P. castellonis Gottsche in Steph. 1918.

Systematic revision of Hoggicosa Roewer, 1960, the Australian ‘bicolor’ group of wolf spiders (Araneae: Lycosidae)

The Australian wolf spider genus Hoggicosa Roewer, 1960 with the type species Hoggicosa errans (Hogg, 1905) is revised to include ten species: Hoggicosa alfi sp. nov. ; Hoggicosa castanea (Hogg, 1905) comb. nov. (= Lycosa errans Hogg, 1905 syn. nov. ; = Lycosa perinflata Pulleine, 1922 syn. nov. ; = Lycosa skeeti Pulleine, 1922 syn. nov. ); Hoggicosa bicolor (McKay, 1973) comb. nov. ; Hoggicosa brennani sp. nov. ; Hoggicosa duracki (McKay, 1975) comb. nov. ; Hoggicosa forresti (McKay, 1973) comb. nov. ; Hoggicosa natashae sp. nov. ; Hoggicosa snelli (McKay, 1975) comb. nov. ; Hoggicosa storri (McKay, 1973) comb. nov. ; and Hoggicosa wolodymyri sp. nov. The Namibian Hoggicosa exigua Roewer, 1960 is transferred to Hogna, Hogna exigua (Roewer, 1960) comb. nov. A phylogenetic analysis including nine Hoggicosa species, 11 lycosine species from Australia and four from overseas, with Arctosa cinerea Fabricius, 1777 as outgroup, supported the monophyly of Hoggicosa, with a larger distance between the epigynum anterior pockets compared to the width of the posterior transverse part. The analysis found that an unusual sexual dimorphism for wolf spiders (females more colourful than males), evident in four species of Hoggicosa, has evolved multiple times. Hoggicosa are burrowing lycosids, several constructing doors from sand or debris, and are predominantly found in semi‐arid to arid regions of Australia. © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 158 , 83–123.     

Re-establishment of the cyrtophorid genus Coeloperix Deroux,nov. gen., with a description of Coeloperix sleighi nov. spec. (Protozoa,Ciliophora, Cyrtophorida)

The cyrtophorid genus Coeloperix, which has remained invalid for over 20 years, is re-established. This taxon is characterized by Lynchellids without podites on the ventral side; somatic kineties making no noticeable naked gap between left and right areas; pre- and post-oral kineties completely separated; two terminal fragments; perioral kineties consisting of one continuous anterior and two detached posterior rows; with cross-striated band around perimeter between ventral and dorsal surfaces. Based on this definition, two nominal species formerly placed in the invalid genus have been included again in Coeloperix: Coeloperix dirempta (Deroux, 1970) nov. comb. [synonym: Lynchella dirempta; Deroux, 1970], C. aspidisciformis (Kahl, 1933) nov. comb. [syn. Lynchella aspidisciformis; Kahl, 1933]. Another two morphotypes C. eforiana (Tucolesco, 1962) nov. comb. [syn. Lynchella eforiana; Tucolesco, 1962] and C. lynchelliformis (Borror, 1972) nov. comb. [syn. Chlamydodon lynchelliformis; Borro, 1972] have been transferred into the new genus. The morphology of living cells and infraciliature of a new species, C. sleighi nov. spec., isolated from the coastal area of China, have been investigated. It is diagnosed by: size about 40×30 μm in vivo; consistently 4 preoral and 15–16 postoral kineties; 12–16 nematodesmata; cross-striated band with two separations in the equatorial area; 3–4 (usually 3) finger-like tentacles on the ventral side; macronucleus ellipsoidal; two contractile vacuoles diagonally located; marine habitat.
