Systematics and cladistics of a new Naupactini genus (Coleoptera: Curculionidae: Entiminae) from the Andes of Colombia and Ecuador

A new genus of broad‐nosed weevils belonging to the tribe Naupactini (Coleoptera: Curculionidae) is described, based on six species from the Páramo–Puna subregion (Andean region) of South America. Three species are new and three have been transferred from the genus Asymmathetes (Asymmathetes nigrans, Asymmathetes rugicollis, and Asymmathetes vulcanorum). The new genus is recognized by the black, denuded, and shiny tegument, the well‐developed pre‐epistome, the elytral base curved backwards on middle, the reduction of the hindwings, and the widely separated procoxae, closer to the anterior than to the posterior margin of the prosternum. A cladistic analysis of the six species of the new genus plus five out‐groups (Amitrus, Amphideritus, Asymmathetes, Melanocyphus, and Trichocyphus), using 49 morphological characters, resulted in a single cladogram. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 166 , 54–71.     

A combined morphological and molecular phylogenetic analysis of Parthenocissus (Vitaceae) and taxonomic implications

Parthenocissus (the Virginia creeper genus, Vitaceae) consists of 13 species and shows a disjunct distribution between Asia and North America. We investigated the inflorescence structure, calyx morphology, appendages on the inner side of petals, leaf epidermis, pollen and seed characters throughout the genus. A combined phylogenetic analysis with 27 morphological and 4137 molecular characters was conducted and the result was largely congruent with that of the previous molecular work, but with higher resolution. The combined analysis identified two clades corresponding to the Asian and North American taxa. Parthenocissus feddei was resolved as closely related to the clade containing P. cuspidifera, P. heterophylla and P. semicordata. The four species share synapomorphies of having conspicuously raised veinlets, an obscurely five‐ (to eight‐) lobed calyx, appendages on the inner side of petals covering the entire length of anthers and foveolate pollen exine ornamentation. Within the Old World clade, the pentafoliolate species were weakly supported as more closely related to species with both simple and trifoliolate leaves. Furthermore, the ancestral states of tendril apices, inflorescence structure, appendages on the inner side of petals and exine ornamentation of pollen grains were reconstructed on the molecular strict consensus tree. The appendages on the inner side of petals and exine ornamentation of pollen grains were suggested to be important characters in the taxonomy of Parthenocissus, especially for species with trifoliolate leaves. Finally, the previous classifications of Parthenocissus were evaluated within the phylogenetic framework. © 2011 The Linnean Society of London, Botanical Journal of the Linnean Society, 2011, ?? , ??–??.     

Palynological survey of subtribe Pithecocteniinae (Bignonieae,Bignoniaceae)

The pollen morphology of subtribe Pithecocteniinae was reviewed. Thirty species of the six genera currently recognized, namely Amphilophium, Distictis, Distictella, Glaziovia, Haplolophium and Pithecoctenium, were considered. All the species surveyed fell into one of the two pollen groups: (1) inaperturate, spheroid pollen; and (2) stephanocolpate, prolate pollen. The former group included the studied species of Distictis, Distictella and Pithecoctenium, the latter species of Amphilophium, Glaziovia and Haplolophium. The variation of exine sculpture and thickness did not show any taxonomic relationships. An argument for considering pollen features, together with other morphological characters, to elucidate monophyletic units within Pithecocteniinae is presented. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society, 2009, 159 , 155–162.     

Systematics of the Miocene–Recent bryozoan genus Pentapora (Cheilostomata)

The four existing species of the ascophoran bryozoan Pentapora Fisher, 1807 are revised, and two new fossil species are introduced: Pentapora lacryma sp. nov. from the Pliocene Coralline Crag Formation of Suffolk, and Pentapora clipeus sp. nov. from the Pliocene of Emilia, Italy. The Arctic species Pentapora boreale Kuklinski & Hayward possesses a lyrula, does not belong in Pentapora, and is a junior synonym of Raymondcia rigida (Lorenz). The morphology of the autozooids is relatively uniform within the genus, and the main distinguishing characters are those of the ovicells and, particularly, the giant avicularia that are developed sporadically in all species apart from Pentapora foliacea, popularly known as ‘Ross coral’. A phylogenetic analysis based on skeletal characters returned a single shortest tree in which the three species of Pentapora from the North Atlantic (P. foliacea, Pentapora pertusa, and P. lacryma sp. nov. ) form a clade crownward of the three basal species from the Mediterranean (Pentapora ottomulleriana, Pentapora fascialis, and P. clipeus sp. nov. ). © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 160 , 17–39.     

Phylogeny and taxonomy of European funnel‐web spiders of the Tegenaria−Malthonica complex (Araneae: Agelenidae) based upon morphological and molecular data

The taxonomy and systematics of European house spiders, currently constituting the ill‐defined Tegenaria?Malthonica complex (including Aterigena) in the family Agelenidae, are revised. In Europe four monophyletic genera and 81 species are defined. One genus, Eratigena gen. nov. , and seven species are described as new; at species level 17 new synonyms and 20 new combinations are proposed, and the original combination of 14 species is reinstated. Five species could not be placed (incertae sedis) because of insufficient material and one taxon is regarded as ‘nomen dubium’. On the basis of a detailed morphological assessment, 88 characters were chosen for a cladistic analysis. Phylogenetically informative characters include mostly spination patterns as well as spinneret and genital structures. In addition to morphology, three gene sections [cytochrome c oxidase subunit 1 (CO1), nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NADH1) 28S] were analysed. Morphological and molecular analyses were performed individually and in combination applying maximum parsimony and Bayesian tree search methods. In all resulting trees Malthonica and Tegenaria in their present composition are either polyphyletic or paraphyletic. Consequently, we redefined the two genera and erected a new genus, Eratigena gen. nov. Identification keys are provided for the European agelenid genera as well as for the European species of Tegenaria and Eratigena gen. nov. The genera and most of the constituent species are described and illustrated. The new classification has also been applied to some extra European members of the Tegenaria‐Malthonica complex resulting in additional three new synonyms, seven reversals to the original combination, and four new combinations. © 2013 The Linnean Society of London     

A morphometric analysis of Daniellia (Fabaceae – Caesalpinioideae)

A multivariate morphometric study of Daniellia, an endemic genus of tropical and subtropical Africa, indicates that nine species may be recognized: D. alsteeniana, D. klainei, D. oblonga, D. ogea, D. oliveri, D. pilosa, D. pynaertii, D. soyauxii and D. thurifera. In our study we found that some characters, not previously studied in detail, were significant in species delimitation: petiole indumentum, petiole width, number and position of glands on the lower surface of the leaflets and presence or absence of glands at the insertion of each pair of leaflets. The rare and scattered material of D. pilosa and D. soyauxii made their classification uncertain, although some qualitative characters support their differentiation. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society, 2009, 159 , 268–279.     

Resurrection in Carapa (Meliaceae): a reassessment of morphological variation and species boundaries using multivariate methods in a phylogenetic context

The taxonomy of the amphi‐Atlantic tree genus Carapa (Meliaceae) has long been controversial. Of the three species currently recognized in the genus, two are known to present substantial morphological variation that has been used in the past to distinguish several taxa, most of which are currently placed in synonymy. Here, a combination of field observations, univariate analyses of leaf, floral and seed characters and principal coordinate analyses of floral characters in the context of a molecular phylogenetic analysis was used to investigate the patterns of variation and delimit morphological species anew in the genus. These results support the recognition of 27 species in Carapa, of which 16 are previously described and 11 are new. In general, phylogenetically related species occurred in the same geographical area, but were morphologically distinct. © 2011 The Linnean Society of London, Botanical Journal of the Linnean Society, 2011, 165 , 186–221.     

From acaveate to caveate: evolution of pollen types in the Rhaponticum group (Asteraceae,Centaureinae) related to extreme conditions

A survey of pollen morphology and ultrastructure within the Rhaponticum group, using both scanning and transmission electron microscopy, revealed two pollen types. Most representatives of the Rhaponticum group exhibited Serratula‐type pollen. The exceptions were the genus Oligochaeta, with Centaurea jacea‐type pollen, and the genus Myopordon, with both types of pollen. Phylogenetic inference within the group indicated that Jacea‐type pollen is derived from Serratula‐type pollen. The fact that Myopordon exhibited a series of pollen types, from Serratula type to Jacea type, suggests that a transition from one form to another has occurred in the genus. Therefore, the factor which has produced this evolutionary tendency should be sought within Myopordon. Jacea‐type pollen is characterized by a decrease in size, ornamentation, the absence of a columellar infratectum and the presence of a cavea. A comparative survey of similar tendencies in other groups, and their correlation with potential functional implications, prompted the hypothesis that the critical factor involved in such evolution of pollen could be habitats with extreme conditions. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 499–510.

Five new species of Hoplitomeryx from the Neogene of Abruzzo and Apulia (central and southern Italy) with revision of the genus and of Hoplitomeryx matthei Leinders, 1983

Six species of Hoplitomeryx from Abruzzo and Apulia are defined, of which five are described as new to science, Hoplitomeryx apruthiensis, Hoplitomeryx apulicus, Hoplitomeryx falcidens, Hoplitomeryx magnus, and Hoplitomeryx minutus, and one is re‐described, Hoplitomeryx matthei Leinders, 1983. A new diagnosis of the genus is also provided. The new species are established only on teeth, maxillary fragments, and jaws. The standing classification of these ungulates is questioned. As Hoplitomeryx shares a mixture of characters with many other ruminants, it is here believed to have derived from a primitive ruminant stock prior to the emergence of advanced ruminant lineages. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 1304–1333.     

Phylogenetic interrelationships,taxonomy, and reductive evolution in the Neotropical electric fish genus Hypopygus (Teleostei,Ostariophysi, Gymnotiformes)

A phylogenetic reconstruction of the Neotropical electric fish genus Hypopygus based on 47 parsimony‐informative morphological characters is presented. A series of synapomorphies support the hypothesis of monophyly of Hypopygus, and partially resolve species‐level relationships within the genus. Hypopygus species are recognized here as miniaturized fishes based on two criteria; first, a derived condition of diminutive body size, and; second, the presence of a suite of reductive morphological characters, including partial or total losses, simplifications, and reductions of the anal‐fin rays, scales, cranial bones, and laterosensory canal system. Reductive characters associated with miniaturization comprise 45% of the total number of characters in the phylogenetic reconstruction of the genus. Miniaturization and reductive morphological evolution in Hypopygus are discussed here in the phylogenetic context. A taxonomic revision of Hypopygus is presented, in which five new species are described, two species previously assigned to the genus are redescribed, and a single known species of Stegostenopos is redescribed and included in Hypopygus as a junior synonym. Distribution maps and a key for all eight valid species of Hypopygus are provided, based on the examination of 5014 catalogued museum specimens. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 1096–1156.     

A new genus of Entiminae from North Africa,supported by a phylogenetic analysis (Coleoptera: Curculionidae: Entiminae)

The genus Holcophloeus gen. nov. is here proposed to include Trachyphloeus cruciatus Seidlitz, 1868, and two new species native to North Africa, based on a phylogenetic analysis and an evaluation of the diagnostic characters. The taxonomic position of Holcophloeus in relation to the tribes Trachyphloeini Lacordaire, 1863, and Holcorhinini Desbrochers, 1898, is discussed, and the new genus is attributed to the Holcorhinini. Holcophloeus laurae sp. nov. from south‐eastern Morocco and Holcophloeus weilli sp. nov. from northern Libya are described and illustrated and a key to the species of the new genus is given. The lectotype of Trachyphloeus cruciatus Seidlitz, 1868, is designated. The genus Massimiellus Borovec, 2009, is transferred from Trachyphloeini to Holcorhinini. © 2013 The Linnean Society of London     

Pollen diversity in Aquifoliales

Aquifoliales, as currently circumscribed, comprise five families and 20 genera, most of which have not been compared with regard to their pollen. Generic relationships within the order have not been fully resolved with molecular data, but pollen can provide a potential source of characters for future phylogenetic studies. To assess diversity in the order, pollen from 19 genera was examined with light and scanning electron microscopy. Pollen is typically tricolpate to triporate, although grains with one to nine pores were observed. Grains are small to medium, with a polar axis of 6–44 μm and an equatorial axis of 10–47 μm. Irregular pollen was recorded from nine genera. Exine patterning is diverse at the generic level and includes psilate, microechinate, striate to reticulate and clavate types, and is quite complex in some genera. All but four genera of Aquifoliales can be readily distinguished by their pollen, if heavy deposits of pollenkitt (present in 11 genera) are removed during and after acetolysis. Pollen from multiple taxa of Gomphandra, the second most diverse genus in the order, was surveyed to investigate species boundaries. Specimens of Gomphandra from continental Asia exhibited seven different pollen morphologies, suggesting that exine patterns may be useful for the recognition of species in that region. © 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, 175 , 169–190.

Pollen morphology supports the transfer of Wendlandia (Rubiaceae) out of Rondeletieae

Pollen morphology of 27 species, eight subspecies and one variety of Wendlandia was studied using scanning electron microscopy (SEM). Wendlandia pollen are monads, radiosymmetric, small in size, tricolporate (rarely tetracolporate or bicolporate) and spheroidal (rarely subprolate or suboblate) in equatorial view. The compound aperture consists of ectocolpus, mesoporus and endocolpus. In addition, reticulate sexine and granular nexine were observed. The pollen wall ultrastructure of two Wendlandia spp. was examined by transmission electron microscopy (TEM). The exine consists of the tectum, columellae, foot layer and endexine. The endexine is thickened into a costa around the aperture. The intine forms a protruding oncus at the aperture. The palynological characters show a remarkable uniformity among the Wendlandia spp. Differences with Rondeletia, the main genus of tribe Rondeletieae, exist in the exine pattern, the endoaperture and the pollen wall structure. Our observations indicated that the endoaperture type and the structure of the pollen wall of Wendlandia were similar to those of the Gardenieae–Pavetteae–Coffeeae–Octotropideae clade, which provided palynological evidence for a closer relationship of Wendlandia to subfamily Ixoroideae and the transfer of Wendlandia out of Rondeletieae. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 164 , 128–141.     

Pollen morphology and systematics of palaeotropical Phyllanthus and related genera of subtribe Phyllanthinae (Euphorbiaceae)

The observations of pollen from 27 species of subtribe Phyllanthinae using scanning electron microscopy reveal considerable morphological diversity in palaeotropical Phyllanthus and the related palaeotropical genera Breynia, Glochidion, and Sauropus. The tribe appears to be monophyletic, but the pollen morphology does not support the monophyly of Phyllanthus or Sauropus. Within Phyllanthus, the pollen characters suggest a close relationship between the subgenera Emblica and Phyllanthodendron. They also reveal a surprising morphological congruence between the pollen grains of section Ceramanthus (subgenus Isocladus) and those of subgenus Eriococcus, although it is not clear whether this similarity is homoplastic. The presence of diploporate colpi is a synapomorphy uniting Breynia and Sauropus, but may be homoplastic in Phyllanthus. The affinities suggested by the morphological features of the pollen in the Phyllanthinae are concordant with recent molecular phylogenies. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157 , 591–608.     

Two new species of the pinnate microsporophyll Pramelreuthia from the upper Triassic of the southwestern United States

Two new species of the enigmatic gymnosperm microsporophyll Pramelreuthia, found in the Upper Triassic Chinle Formation at five localities in the southwestern United States, provide significant new evidence on key morphological characters of the genus and extend its known geographical range. These new fossils also demonstrate that the genus was polytypic and reveal the plant megafossil sources for several common and geographically widespread dispersed Upper Triassic microfossil taxa. The genus Pramelreuthia, which until this study was known only from a single specimen from the Upper Triassic of Austria, is a planar pinnate structure consisting of a slender naked axis bearing stalked synangia in opposite to subopposite pairs. Synangia of all three species of Pramelreuthia are oval to subrectangular in lateral view and are composed of two adpressed flattened valves each of which contains up to 20 or more elongate, subcylindrical, tapered sporangia that bear nonstriate bisaccate pollen. Pramelreuthia yazzi sp. nov. is slightly smaller than the type species P. haberfelneri, and its synangia contain pollen generally similar in morphology and size to several species of the dispersed pollen taxon Pityosporites, including P. chinleana, P. oldhamensis, and P. devolvens. Pramelreuthia dubielii sp. nov. is much larger than the other two species; its synangia contain pollen similar to the dispersed pollen species Protodiploxypinus americus.     

The taxonomical status and diversity of Balkan sironids (Opiliones,Cyphophthalmi) with descriptions of twelve new species

The resurrected genus Cyphophthalmus is defined morphoanatomically and its relationship with the genus Siro, from which it has been separated, is discussed. The genus Tranteeva is synonymized with Cyphophthalmus. Twelve new species are here described: Cyphophthalmus paragamiani , Cyphophthalmus thracicus , Cyphophthalmus gordani , Cyphophthalmus neretvanus , Cyphophthalmus kratochvili , Cyphophthalmus conocephalus , Cyphophthalmus trebinjanus , Cyphophthalmus ognjenovici , Cyphophthalmus martensi , Cyphophthalmus rumijae , Cyphophthalmus zetae , Cyphophthalmus hlavaci , two re‐described: Cyphophthalmus minutus and Cyphophthalmus corfuanus, and for C. corfuanus, Cyphophthalmus bithynicus, and Cyphophthalmus yalovensis a new status is given. Relevant taxonomic characters are reviewed to illustrate the diversity of Balkan sironids. Phyletic relationships amongst species are reviewed and discussed. The results provide the basis for discussion on the relevance of minute morphological differences in the taxonomy of Cyphophthalmi. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 156 , 260–318.
