New Combination

The composition of the subtribe Manobiina Bechyné et Bechyné, 1975 is reconsidered based on cladistic analysis of morphological characters. The following genera are retained: Alema Sharp, 1876, Analema Samuelson, 1973, Eudoliamorpha Scherer, 1989, Exoceras Jacoby, 1891, Leptophysa Baly, 1877, Lipromela Chen, 1933, Lipromima Heikertinger, 1924, Lipromorpha Chûjô et Kimoto, 1960, Liprus Motschulsky, 1860, Manobia Jacoby, 1885, Pseudoliprus Chûjô et Kimoto, 1960, and Taiwanoliprus Komiya, 2006. A description of the subtribe Manobiina, diagnosis and key to genera are given. A morphological analysis of the genera attributed to the subtribe is provided and discussed. A possible fossil representative of Manobiina is recorded from Late Eocene of Rovno amber. A new combination is proposed: Leptophysa trinitatis (Bryant, 1927) = Exoceras trinitatis (Bryant, 1927) comb.n. The lectotype of Liprus punctatostriatus Motschulsky, 1860 is designated.

The Creation

AbstractIn this study Parorphula is re-described based on characters from the external morphology and genitalia. This genus comprised two species: P. pallidinota and P. latipennis, that were described based mostly on characters from external morphology. The morphological analysis conducted in this study plus the support of results from a cladistic analysis showed that external morphological characters justify the creation of a new genus for P. latipennis. Therefore, the genus Neorphula is proposed and the new combination is established.

Qualitative Characters

We present a cladistic analysis of all the species of Smallanthus. Six taxa within Rumfordia, Ichthyothere, Acanthospermum and Tridax served as outgroups. We evaluated the monophyly and the relationships between the species of Smallanthus through a maximum parsimony study based on morphological data. The matrix included 31 qualitative characters from floral and vegetative parts of the specimens. We also explored the phylogenetic significance of treating quantitative characters as continuous. Only one most parsimonious tree was obtained. In agreement with previous phylogenetic studies based on molecular data, we recovered a monophyletic Smallanthus. The presence of ray corollas, densely pubescent at the base, was the synapomorphy that defined Smallanthus. Smallanthus microcephalus and two other major clades were recovered. The first clade included S. glabratus, S. fruticosus, S. jelskii and S. pyramidalis, while the second one contained the remaining species of Smallanthus. The analysis recovered one species of Rumfordia as sister to Smallanthus. We present a new combination, Smallanthus cocuyensis, based on morphological analysis of the type specimen.

Close Relationship

The tribe Junoniini is a predominantly Paleotropical group of the cosmopolitan butterfly subfamily Nymphalinae (Nymphalidae), with highest diversity in the Afrotropical region. Its systematics and relationships are not entirely resolved. Question marks remain concerning the validity of some genera; and the apparently close relationship between the Indo-Australian genus Yoma and the Afrotropical Protogoniomorpha, as evidenced by molecular phylogenies, remains a puzzle. Here, we present a cladistic analysis, based on 42 characters of the male and female genitalia of 41 species of Junoniini belonging to six genera, nearly all of them continental Afrotropical, and 3 species of two Indo-Australian genera Yoma and Rhinopalpa. A ML COI-based tree is produced for 36 species of Afrotropical Junoniini and Yoma. The molecular data are consistent with previous studies. However, morphological analysis does not confirm a close relationship between Protogoniomorpha and Yoma. Despite the evolution of a number of modifications, the male genitalia within all genera and species of the Junoniini share a cohesive build plan, in particular a transformed sacculus, from which Yoma is highly divergent. The position of the genus Kamilla, previously synonymized with Junonia, is discussed. Three East African coast taxa, Junonia elgiva stat. reinst., Protogoniomorpha nebulosa stat. reinst. and Salamis amaniensis stat. reinst., and one from central Africa, Precis silvicola stat. reinst. are raised to species level, based on comparative analysis of their male genitalia.

This study represents the first combined molecular and morphological analysis for the mayfly family Ephemerellidae (Ephemeroptera), with a focus on the relationships of genera and species groups of the subfamily Ephemerellinae. The phylogeny was constructed based on DNA sequence data from 3 nuclear (18S rDNA, 28S rDNA, histone H3) and 2 mitochondrial (12S rDNA, 16S rDNA) genes, and 23 morphological characters. Taxon sampling for Ephemerellidae included exemplars from all 25 extant genus groups and additional representatives from those genera with the highest diversity. Ephemerellidae appears to consist of three major clades. Ephemerella, the largest genus of Ephemerellidae, and Serratella were not supported as monophyletic, and each had representatives in two of the three major clades. However, the genera Drunella and Cincticostella were supported as monophyletic. Lineages strongly supported as monophyletic include a grouping of the Timpanoginae genera Timpanoga, Dannella, Dentatella and Eurylophella, and groupings of the Ephemerellinae genera Torleya, Hyrtanella and Crinitella and the genera Kangella, Uracanthella and Teloganopsis. The placement of the Timpanoginae genus Attenella fell within Ephemerellinae, based on molecular and combined data, but it grouped with other Timpanoginae based on morphological data alone. Further study and analysis of Ephemerellidae morphology is needed, and classification should be revised, if it is to reflect phylogenetic relationships.

A new monotypic genus, Turneroconcha, is established for T. magnifica (Boss & Turner) which was originally assigned to the genus Calyptogena Dall. The distinguishing morphological characters of the new genus are the combination of both conchological and anatomical features including: the presence of only two tooth elements in the right valve; submerged location of the posterior part of the posterior lamellar ligament layer; the absence of a subumbonal pit, lunular incision, escutcheon and pallial sinus; the presence of both pairs of demibranchs; the tubular structure of marginal parts of the interlamellar septa in gills; an inner valve of the inhalant siphon without processes; tentaculate inner mantle fold 3 and a Z-shaped digestive tract. Analysis of morphological data on Recent and fossil pliocardiines shows that Turneroconcha gen. nov. can be presently considered as a monotypic genus. The comparative morphological analysis of the new genus with described pliocardiine genera is consistent with available molecular results. Turneroconcha gen. nov. is endemic to the East-Pacific Rise and Galapagos Rift and occurs at water depths of 2251 to 2791 m. It is the only pliocardiine genus known so far with a mainly epifaunal life habit. No fossils of Turneroconcha gen. nov. are known.

Phylogenetic Hypotheses

Andersen's 1912 monograph on megachiropterans remains the definitive work on the systematics of this group. Andersen argued that the Macroglossinae, containing the eonycterine and notopterine sections, are a monophyletic sister-group to other fruitbats (i.e. Andersen's Rousettus, Cynopterus and Epomophorus sections). Two recent molecular studies (DNA hybridisation and restriction mapping of ribosomal cistrons), as well as an analysis of female reproductive characters, challenge the monophyly of the Macroglossinae and several of Andersen's other conclusions such as the phylogenetic position of Nyctimene. We performed a cladistic analysis on 36 morphological characters, including 33 that were gleaned from Andersen, to determine whether phylogenetic hypotheses based on modem phylogenetic methods are in agreement with Andersen's original conclusions and to compare morphological and molecular phylogenetic hypotheses. Minimum-length trees based on parsimony are largely consistent with Andersen and support (1) a monophyletic Macroglossinae, within which the eonycterine section is paraphyletic with respect to a monophyletic notopterine section, (2) a monophyletic Cynopterus section, excepting the exclusion of Myonycteris, (3) a monophyletic Epomophorus section, excepting the exclusion of Plerotes, and (4) a paraphyletic Rousettus section, with several of the Rousettus-like forms branching off near the base of the tree. Bootstrapping analyses on a reduced data-set that included taxa shared in common with the DNA hybridisation study did not provide strong support (greater than or equal to 95%) for any clades but did provide moderate support (greater than or equal to 70) for several clades, including a monophyletic Macroglossinae. These findings are in marked contrast to the DNA hybridisation phylogeny. A high index of between-data-set incongruence is further evidence for the clash between DNA hybridisation and morphology. A phylogenetic framework was constructed on the basis of morphological data and DNA hybridisation data using a criterion of moderate support and shows little resolution, whereas employing a criterion of strong support produced a framework resolving several additional nodes. One implication of this framework is that characteristic macroglossine features such as a long tongue with a thick carpet of filiform papillae have evolved independently on several occasions (or evolved once and were lost several times). Rates of character evolution for the morphological characters employed in our analysis were calculated using divergence times estimated from DNA hybridisation data. Rates have apparently been fastest in the interior branches, and slower along the external branches, which suggests an early adaptive radiation in the history of fruitbats.

The World species of the genus Ischnopoda, Stephens are revised and the genus is redefined. The genera Amanota Casey and Rechota Sharp are considered as new synonyms of Ischnopoda. The revised Ischnopoda includes thirty-eight species, 13 of which are described as new: Ischnopoda assingi sp. n., I. boliviana sp. n., I. brasiliana sp. n., I. chilensis sp. n., I. depressa sp. n., I. drugmandi sp. n., I. lingshani sp. n., I. nebulosa sp. n., I. pretiosa sp. n., I. pseudobasalis sp. n., I. rugosa sp. n., I. schuelkei sp. n. and I. spissata sp. n. The following new synonymies are proposed (each first name being valid): Ischnopoda basalis (Cameron, 1923) = Amanota bimarginata Pace, 1996, syn. n.; I. capensis (Casey, 1906) = Falagria arachnipes Fauvel, 1907, syn. n. = Amanota densicollis Pace, 1986, syn. n. = A. rufobrunnea Tottenham, 1957, syn. n.; Ischnopoda rudicollis (Bernhauer, 1934) = Amanota purpurascens Tottenham, 1957, syn. n. = A. wittei Cameron, 1950, syn. n. The following synonym is confirmed: I. leucopus (Marsham, 1802) = Tachyusa chalybea Erichson, 1839. Lectotypes are designated for Amanota capensis Casey, A. semiopaca Cameron, Ischnopoda subaenea Eppelsheim, Rechota impressa Sharp, Staphylinus leucopus Marsham, Tachyusa abyssina Bernhauer, T. burgeoni Bernhauer, T. chalybea Erichson, T. fissicollis Fairmaire et Germain, T. rudicollis Bernhauer, T. scitula Erichson, T. seticornis Sharp, T. sparsa Sharp and T. umbratica Erichson. Twenty-one species are given in new combination. All species are briefly described/redescribed and illustrated. An identification key to the World species of Ischnopoda is provided. A phylogeny of thirty-eight species belonging to the genus Ischnopoda is proposed, based on fifty-two morphological characters. The cladistic analysis provides a single most parsimonious tree. The genus Ischnopoda is redefined and species group are introduced and defined: leucopus group (eleven species), impressa group (nine species) and capensis group (eighteen species).

The Family

A cladistic analysis of the genera of the family ‘Lafoeidae’ was performed in order to investigate suprageneric classifications and the boundaries of the family, as well as to organise the available morphological data and discuss the possible evolution of some morphological characters. Our results suggest that the former ‘Lafoeidae’ must be separated into two families: the Hebellidae and the Lafoeidae (including the subfamilies Lafoeinae and Zygophylacinae).

Molecular Phylogenetic Data

The snow hebes, formerly comprising the genus Chionohebe, are here included within Veronica (Plantaginaceae). The five species (including two subspecies) of snow hebes recognised here are cushions or subshrubs that occur exclusively in high-elevation habitats of Australia and the South Island of New Zealand. Species delimitation among the cushion snow hebes is very difficult because of the reduced pulvinate habit, solitary flowers and few gross-morphological characters useful for identification. To address species limits, investigate intraspecific patterns and revise the taxonomy of the snow hebes, morphological analyses were conducted and the results compared with previously published molecular phylogenetic data. Ordination and clustering analyses of morphological data showed some taxonomic structuring; however, species clusters were not widely separated from one another. Morphological and amplified fragment length polymorphism (AFLP) data show that the cushion species are clearly distinguished from the subshrub species, V. densifolia (F.Muell.) F.Muell. Among the four cushion species (V. chionohebe Garn.-Jones, V. ciliolata (Hook.f.) Cheeseman, V. pulvinaris (Hook.f.) Cheeseman, V. thomsonii (Buchanan) Cheeseman), the distribution of leaf trichomes is important for species identification, particularly when used in conjunction with ovary vestiture, capsule size, and/or seed size. One new combination V. ciliolata subsp. fiordensis (Ashwin) Meudt is proposed, and V. uniflora Kirk is treated as a naturally occurring hybrid V. × uniflora (V. densifolia × V. thomsonii). Complete synonymies, descriptions, illustrations and range maps are provided for each species, as well as a key to all species and a discussion of putative hybrids.
