Fungal Genus

The taxonomy and phylogenetic relationships of the fungal genus Fimetariella (Ascomycotina, Lasiosphaeriaceae) are discussed. A revised generic description and key are presented. Descriptions and illustrations are provided for all taxa. Fimetariella dunarum n.comb. and Fimetariella apotoma, Fimetariella brachycaulina, Fimetariella dolichopoda, Fimetariella macromischa, Fimetariella microsperma, and Fimetariella tetraspora n.spp. are proposed. A phialidic anamorph resembling Cladorrhinum is reported for F. microsperma. The ascospores of the type species Fimetariella rabenhorstii are considered to possess two terminal germ pores, one large pore and one very small pore, along with several small, apparently nonfunctional pores. A key to the genera with these minor pores is included. Key words: Fimetariella, Cladorrhinum, coprophilous, fungi, keys, taxonomy.

Species Descriptions

The phylogenetic relationships of 23 oxyurid species from five genera (21 parasite species of the Palaearctic Testudinidae, 1 parasite species of Uromastix acanthinurus Bell, 1825 from Algeria, and 1 parasite species of Cteno sa ura pectinata (Wiegmann, 1834) from Mexico) were investigated using 30 morphological characters obtained from species descriptions. The nonweighted analysis produced one shortest tree. All species of the ingroup form a monophyletic group and the oxyurid species of Testudinidae form a monophyletic group. The type species of the genus Alaeuris Thapar, 1925 is the basal member of the species parasitizing Testudinidae. The analysis confirms the monophyly of the genus Thaparia Ortlepp, 1933, whereas the genera Mehdiella Seurat, 1918 and Tachygonetria Wedl, 1862 are considered paraphyletic groups. The large diversification in the genus Tachygonetria is linked to their position in the host caecum. The ancestral state is in the paramucous and the derived state is in the centre of the caecum. This suggests that recent speciation in the group occurs in the centre of the caecum.

AbstractThe species of Synophromorpha Ashmead (Hymenoptera: Cynipidae) are reviewed. One new species is described (Synophromorpha kaulbarsi; type locality: Naupan, Puebla, Mexico). The previously described species (S. rubi Weld, S. sylvestris (O.S.), and S. terricola Weld) are redescribed, and a key to species is presented. All species are illustrated for the first time. Synophromorpha sylvestris is designated type-species for the genus and a lectotype is chosen. Hypotheses on the phylogenetic relationships between the species of Synophromorpha are presented.

<p>O "Tree Thinking" é tido como a metodologia dominante na Biologia Sistemática atual. Todavia, críticas aos procedimentos executados pela mesma são diversas. Neste trabalho serão apresentadas e defendidas aquelas feitas por Fitzhugh no que tange a sua base filosófica e as consequências de tais modificações. Assim, o presente trabalho tem como objetivo demonstrar que o "Tree Thinking" é incompleto, por não reconhecer que as relações filogenéticas são do tipo causal, i.e., são hipóteses explanatórias, sumarizadas de forma prévia em um esquete explanatório (cladograma). Além disso, para embasar tal argumentação, será apresentada uma discussão sobre a definição e os objetivos da Biologia Sistemática e do "Tree Thinking". Como resultado, será possível observar uma confusão entre classificar e sistematizar o conhecimento por aqueles que seguem o "Tree Thinking". Ademais, o "Tree Thinking" falha na aquisição de explicações causais quanto à origem e fixação das características estudadas. Desta forma, o "Tree Thinking" pode ser considerado como uma prática incompleta dentro da Biologia Sistemática e, portanto, recomenda-se a aplicação das propostas de Fitzhugh.</p><p><strong>Palavras chave</strong>: Biologia Sistemática, Cladística, Fitzhugh, Hennig, Sistemática Filogenética, Zimmerman.</p><p><strong>"Tree Thinking" Criticism: elucidating the meaning of phylogenetic relationships</strong></p><p><strong>Abstract</strong>: The "Tree Thinking" is regarded as the dominant methodology in current Systematic Biology. However, criticisms of the procedures carried out by it are diverse. Here the criticisms made by Fitzhugh regarding its philosophical basis and the consequences of such modifications are presented and defended. Thus, the present work aims to demonstrate that "Tree Thinking", as it has been used, is incomplete because it does not recognize that phylogenetic relationships are of the causal type previously summarized in an explanatory sketch (cladogram). In addition, to support such an argument, a discussion on the definition and objectives of Systematic Biology and "Tree Thinking" is provided. As a result, it is possible to observe confusion between classifying and systematizing the knowledge by those who follow "Tree Thinking". In addition, "Tree Thinking" fails to provide causal explanations regarding the origin and fixation of the characteristics studied. In this way, "Tree Thinking" can be considered an incomplete practice within Systematic Biology and, therefore, the application of the proposals of Fitzhugh are recommended.</p><p><strong>Key words</strong>: Systematic Biology, Cladistics, Fitzhugh, Hennig, Systematic Phylogenetics, Zimmerman.</p>

Takahashi (1942) described Dialeurotrachelus cambodiensis, the type species of the monotypic whitefly genus, Dialeurotrachelus Takahashi from three syntype specimens collected on an unidentified tree in Cambodia, which were subsequently lost or destroyed. It was rediscovered after eight decades in the Indian territories of the Andaman and Nicobar Islands. A neotype is designated for D. cambodiensis Takahashi, from specimens collected on Diospyros kurzii Hiern (Ebenaceae) from Andaman Island, India. It is recorded for the first time from the Indian territories, Andaman and Nicobar Islands. Pupal morphology is assessed for redefining the generic description with differential diagnoses from related genera, and anomalies involved with structure of the vasiform orifice and associated structures are discussed. Illustrations are provided of the puparia in life, camera lucida drawings, slide mounts, and scanning electron photomicrographs.

The present study is the first report of phylogenetic relationships between some economically important members of Amaranthaceae and Chenopodiaceae of Lower Gangetic Plains of India, using RAPD and ISSR markers. A total of 293 RAPD and 177 ISSR fragments were generated with 15 (out of 50) decamer arbitrary primers and 11 (out of 30) microsatellite repeat anchored primers, respectively. Mean genetic similarities were estimated at 0.47 and 0.45 using RAPDs and ISSRs, respectively. The members of Chenopodiaceae are separated from those of Amaranthaceae in both the cases. The mantel test between the two Jaccard's similarity matrices gave r = 0.83, showing good correlation between RAPD and ISSR based similarities. However, in both the dendrograms Celosia sp. showed distant relationships with other amaranths.

Bitunicate Ascus

A phylogenetic working hypothesis of euascomycete relationships is presented. Paraphysoidal ascolocular fungi are monophyletic and ascohymenial fungi are paraphyletic as paraphyses are considered plesiomorphic and paraphysoids apomorphic within euascomycete fungi. As a result it is not necessary to postulate parallel evolution of the bitunicate ascus, and furthermore presence of paraphyses in the prototunicate caliciaceous fungi is no longer in conflict with paraphyses in ascohymenial fungi. A cladistic outline of the order Arthoniales with special focus on the Roccellaceae including 20 taxa and 92 characters is presented. The type species of all genera considered are used as terminal taxa. It is suggested that the type species of Arthothelium should be excluded from the order Arthoniales. The Arthoniaceae are paraphyletic as Arthonia radiata and Arthothelium spectabile form a grade pair. The family Roccellaceae is monophyletic and corroborated in its traditional sense, but some rearrangements within the family are made. Opegrapha vulgata and Lecanactis abietina form a pair, but the family Opegraphaceae is paraphyletic if the pair Chiodecton sphaerale and Schismatomma pericleum are included. The originally described ascoma of the species Darbishirella gracillima, Ingaderia pulcherrima, and Reinkella fragillima are found to be lichenicolous fungi. The mycobiont ascomata of Darbishirella gracillima produce 3- not 2-septate spores. No ascomata of the mycobionts of the two latter species have as yet been found. Key words: Euascomycetes, Arthoniales, Roccellaceae, phylogeny, cladistics, lichenicolous.

The phylogenetic relationships of the Australian scincid lizards currently assigned to the genus Leiolopisma have been examined by quantitative micro-complement fixation (MC'F) comparisons of serum albumin. The results of these comparisons do not support the monophyly implicit in these species' current congeneric status, but suggest instead that the Australian species of Leiolopisma belong to several distinct phyletic lineages within the Eugongylus group. These findings are supported by several sets of non-biochemical characters, including features of scalation, osteology and karyotype. None of the Australian species shares a close relationship with the type-species of Leiolopisrna (L. telfairii), and so a new taxonomic arrangement is proposed which distributes them among the following genera: Bartleia, gen. nov. (jigurru); Bassiana, gen. nov. (duperreyi, platynotum and trilineata); Cautula, gen. nov. (zia); Niveoscincus, gen. nov. (coventryi, greeni, metallicus, microlepidotus, ocellatus, orocryptus, palfreymani and pretiosus); and Pseudemoia Fuhn, 1967 (baudini, entrecasteauxii Group 1; entrecasteauxii Group 2, rawlinsoni and spenceri). Preliminary comparisons suggest that other Leiolopisma species, from New Caledonia, Lord Howe I. and New Zealand, belong to phyletic lineages which are distinct from any of the Australian 'Leiolopisma' and from the type-species.

Sets of small ribosomal DNA (SSU rDNA) and large ribosomal DNA (LSU rDNA) sequences were obtained for Philometroides moraveci Vismanis & Yunchis, 1994, Philometra kotlani (Molnár, 1969), Philometra rischta Skrjabin, 1923, Philometra cf. obturans (Prenant, 1886) (Philometridae), Sinoichthyonema amuri (Garkavi, 1972), Agrachanus scardinii (Molnár, 1966), Kalmanmolnaria intestinalis (Dogiel & Bychowsky, 1934) and Skrjabillanus tincae Shigin & Shigina, 1958 (Skrjabillanidae). Phylogenetic analysis of SSU rDNA data shows that dracunculoid nematodes are divided into two well-supported clades designated as Clade I and Clade II, respectively. Clade I includes the type species of the genus Philonema Kuitunen-Ekbaum, 1933, some species from the family Daniconematidae Moravec & Køie, 1987 and two subfamilies of skrjabillanids, Skrjabillaninae Shigin & Shigina, 1958 and Esocineminae Moravec, 2006. Clade II unites species from the families Dracunculidae Stiles, 1907, Micropleuridae Baylis & Daubney, 1926 and Philometridae Baylis & Daubney, 1926. Within the Philometridae, there are several well-supported groups of species, one of which unites freshwater Philometra spp. from the Palearctic cyprinids, identified as P. kotlani, P rischta, P. ovata (Zeder, 1803) and P. cyprinirutili (Creplin, 1825). However, the phylogenetic relationships of most philometrids are unresolved. An analysis of partial SSU and LSU rDNA sequences indicates that there is no direct phylogenetic relationship between Agrachanus Tikhomirova, 1971 (type species Skrjabillanus scardinii Molnár, 1966) and Skrjabillanus Shigin & Shigina, 1958 (type species Sk. tincae), which means that the genus Agrachanus can be resurrected. Our study confirms that Philonematinae Ivashkin, Sobolev & Khromova, 1971 should be elevated to the family rank. We formally establish the family Philonematidae Ivashkin, Sobolev & Khromova, 1971 stat. nov. We also suggest combining the superfamilies Dracunculoidea Stiles, 1907 and Camallanoidea Railliet & Henry, 1915 into the infraorder Camallanomorpha Roberts, Janovy & Nadler, 2013.
