The phylogenetic relationships among selected species and genera of Mesoveliidae (Insecta: Hemiptera: Heteroptera: Gerromorpha) were investigated in a parsimony analysis of 2858 bp of DNA sequence data from the genes encoding COI + II, 16S rRNA and 28S rRNA. The resulting phylogeny showed that Mesoveloidea williamsiHungerford, 1929, from the subfamily Madeoveliinae, was sister group to Mniovelia Andersen & J.T. Polhemus, 1980, from the Mesoveliinae, thus making the latter subfamily paraphyletic. The genus MesoveliaMulsant & Rey, 1852 also showed to be paraphyletic, since an undescribed Laotian relative of M. indicaHorváth, 1915 and M. ujhelyiiLundblad, 1933 resulted as sister group to PhrynoveliaHorváth, 1915; and M. amoenaUhler, 1894 was sister species to Speovelia maritimaEsaki, 1929. Whereas these relationships were poorly or moderately supported, the remaining species of Mesovelia formed two distinct and well-supported clades, one comprising M. horvathiLundblad, 1933, M. hackeriHarris & Drake, 1941, and two undescribed species from Nigeria and New Caledonia, and another comprising M. vittigeraHorváth, 1895, M. stysi J.T. Polhemus & D.A. Polhemus, 2000, M. ebbenielseniAndersen & Weir, 2004, M. furcata Mulsant & Rey, 1952, and M. mulsantiWhite, 1879. A large genetic difference was found between populations of M. vittigera from Europe and Africa on one side and populations from Australia and New Caledonia on the other. DNA sequence data from a Japanese “M. vittigera” obtained from GenBank placed the specimen as strongly supported sister group to a Danish specimen of M. furcata. Comparisons of the 28S rRNA sequence data between the two specimens revealed a single C/T transition, while comparison with a Chinese female of M. furcata revealed one A/G and one C/T transition, thus suggesting mislabelling of the Japanese specimen, or an unrecognized presence of M. furcata in Japan. Considerable genetic differentiation was found between specimens of M. horvathi from Australia, New Caledonia, New Guinea, and Laos, and between sympatric specimens of M. mulsanti from Honduras, thus supporting earlier ideas of species-complexes in these two clades. Samples of Austrovelia caledonicaMalipatil & Monteith, 1983 from New Caledonia and Mniovelia kuscheli Andersen & J.T. Polhemus, 1980 from New Zealand’s North Island also revealed considerable intraspecific divergences indicating genetic isolation among geographically separated populations on these ancient islands.

Molecular Phylogenies

The monotypic genus Perssoniella with P. vitreocincta Herzog, endemic to New Caledonia, possesses a series of unique morphological characters and it has been assumed that the genus, assigned to the family Perssoniellaceae and suborder Perssoniellineae, is very isolated but sister to the family Schistochilaceae. The systematic identity of Perssoniella vitreocincta was studied using DNA sequence data for the chloroplast rbcL, rps4 and trnL-F regions. Our analyses placed Perssoniella vitreocincta within the family Schistochilaceae, and within Schistochila itself, with strong support. It suggests that retaining Perssoniella as an independent genus is untenable and we transfer it to the genus Schistochila. Our results indicate that Perssoniella vitreocincta is not an archaic species, as presupposed earlier. The differentiating characters in Perssoniella are mostly probably later derived, rather than ancestral. Our analyses also placed Pachyschistochila and Paraschistochila within Schistochila, again with strong support. We also transfer these two genera to Schistochila.

Future Revision

The phylogenetic relationships among selected species and genera of Gerrinae (Heteroptera: Gerridae) were investigated in a parsimony analysis of 2268 bp of DNA sequence data from the genes encoding COI + II, 16S rRNA and 28S rRNA. The taxa represented 12 of 15 recognized genera of Gerrinae and with outgroup taxa from all other subfamilies of Gerridae, including three of five recognized genera of Eotrechinae, which is considered the sister-group of Gerrinae. The resulting phylogeny shows that Gerrinae is not monophyletic, since a clade comprising Gerris, Aquarius, Limnoporus, Tachygerris, Eurygerris and Gigantometra is more closely related to representatives of the subfamily Eotrechinae than to a clade comprising Limnogonus, Neogerris, Limnometra, Tenagogerris and Tenagogonus. The two currently recognized gerrine tribes, Tachygerrini and Gerrini, were also paraphyletic, since Eurygerris was sister-group to Gigantometra, while Tachygerris was sister-group to Limnoporus + Aquarius + Gerris. Limnogonus and Neogerris were found to be strongly supported sister-taxa, and their sister-group was a clade comprising Limnometra, Tenagogerris and Tenagogonus, none of which were monophyletic. Finally, Aquarius chilensis (Berg, 1881) was sister-group to a clade comprising Aquarius amplus (Drake & Harris, 1938), A. remigis (Say, 1832) and A. remigoides (Gallant & Fairbairn, 1993), recognized as the A. remigis species group, and the entire clade was sister-group to Gerris. Based on the phylogenetic reconstruction, we outline possible diagnostic character combinations for a future revision of the Gerrinae and discuss the fossil record. While some of the relationships reinstate earlier ideas, e.g., Limnogonus and Neogerris being sister groups, many others are poorly supported and poorly diagnosed, and therefore, we retain from drawing taxonomic conclusions until data is available from the remaining genera, which can support a future generic revision of the Gerrinae. The updated checklist of species assigned to the subfamily is therefore based on the established taxonomy.

AbstractLichen thalli provide a long-lived and stable habitat for colonization by a wide range of microorganisms. Increased interest in these lichen-associated microbial communities has revealed an impressive diversity of fungi, including several novel lineages which still await formal taxonomic recognition. Among these, members of the Eurotiomycetes and Dothideomycetes usually occur asymptomatically in the lichen thalli, even if they share ancestry with fungi that may be parasitic on their host. Mycelia of the isolates are characterized by melanized cell walls and the fungi display exclusively asexual propagation. Their taxonomic placement requires, therefore, the use of DNA sequence data. Here, we consider recently published sequence data from lichen-associated fungi and characterize and formally describe two new, individually monophyletic lineages at family, genus, and species levels. The Pleostigmataceae fam. nov. and Melanina gen. nov. both comprise rock-inhabiting fungi that associate with epilithic, crust-forming lichens in subalpine habitats. The phylogenetic placement and the monophyly of Pleostigmataceae lack statistical support, but the family was resolved as sister to the order Verrucariales. This family comprises the species Pleostigma alpinum sp. nov., P. frigidum sp. nov., P. jungermannicola, and P. lichenophilum sp. nov. The placement of the genus Melanina is supported as a lineage within the Chaetothyriales. To date, this genus comprises the single species M. gunde-cimermaniae sp. nov. and forms a sister group to a large lineage including Herpotrichiellaceae, Chaetothyriaceae, Cyphellophoraceae, and Trichomeriaceae. The new phylogenetic analysis of the subclass Chaetothyiomycetidae provides new insight into genus and family level delimitation and classification of this ecologically diverse group of fungi.

The Family

The Opiliones family Neopilionidae is restricted to the terranes of the former temperate Gondwana: South America, Africa, Australia, New Caledonia and New Zealand. Despite decades of morphological study of this unique fauna, it has been difficult reconciling the classic species of the group (some described over a century ago) with recent cladistic morphological work and previous molecular work. Here we attempted to investigate the pattern and timing of diversification of Neopilionidae by sampling across the distribution range of the family and sequencing three markers commonly used in Sanger-based approaches (18S rRNA, 28S rRNA and cytochrome-c oxidase subunit I). We recovered a well-supported and stable clade including Ballarra (an Australian ballarrine) and the Enantiobuninae from South America, Australia, New Caledonia and New Zealand, but excluding Vibone (a ballarrine from South Africa). We further found a division between West and East Gondwana, with the South American Thrasychirus/Thrasychiroides always being sister group to an Australian–Zealandian (i.e. Australia + New Zealand + New Caledonia) clade. Resolution of the Australian–Zealandian taxa was analysis-dependent, but some analyses found Martensopsalis, from New Caledonia, as the sister group to an Australian–New Zealand clade. Likewise, the species from New Zealand formed a clade in some analyses, but Mangatangi often came out as a separate lineage from the remaining species. However, the Australian taxa never constituted a monophyletic group, with Ballarra always segregating from the remaining Australian species, which in turn constituted 1–3 clades, depending on the analysis. Our results identify several generic inconsistencies, including the possibility of Thrasychiroides nested within Thrasychirus, Forsteropsalis being paraphyletic with respect to Pantopsalis, and multiple lineages of Megalopsalis in Australia. In addition, the New Zealand Megalopsalis need generic reassignment: Megalopsalis triascuta will require its own genus and M. turneri is here transferred to Forsteropsalis, as Forsteropsalis turneri (Marples, 1944), comb. nov.

Multilocus DNA sequence data were used to assess the genetic diversity and evolutionary relationships of 67Fusariumstrains from veterinary sources, most of which were from the United States. Molecular phylogenetic analyses revealed that the strains comprised 23 phylogenetically distinct species, all but two of which were previously known to infect humans, distributed among eight species complexes. The majority of the veterinary isolates (47/67 = 70.1%) were nested within theFusarium solanispecies complex (FSSC), and these included 8 phylospecies and 33 unique 3-locus sequence types (STs). Three of the FSSC species (Fusarium falciforme,Fusarium keratoplasticum, andFusariumsp. FSSC 12) accounted for four-fifths of the veterinary strains (38/47) and STs (27/33) within this clade. Most of theF. falciformestrains (12/15) were recovered from equine keratitis infections; however, strains ofF. keratoplasticumandFusariumsp. FSSC 12 were mostly (25/27) isolated from marine vertebrates and invertebrates. Our sampling suggests that theFusarium incarnatum-equisetispecies complex (FIESC), with eight mycoses-associated species, may represent the second most important clade of veterinary relevance withinFusarium. Six of the multilocus STs within the FSSC (3+4-eee, 1-b, 12-a, 12-b, 12-f, and 12-h) and one each within the FIESC (1-a) and theFusarium oxysporumspecies complex (ST-33) were widespread geographically, including three STs with transoceanic disjunctions. In conclusion, fusaria associated with veterinary mycoses are phylogenetically diverse and typically can only be identified to the species level using DNA sequence data from portions of one or more informative genes.

Two new species of the doryctine genus Iare, I. mexicanus sp. nov. and I. cheguevarai sp. nov., are genetically and morphologically described from a tropical dry forest in Jalisco, Mexico. Iare belokobylskiji Marsh is also reported for the latter region. These species represent the northernmost distribution records for the genus. A simultaneous Bayesian analysis with COI and 28S DNA sequence data recovered the three examined species of Iare within a single clade, though with low support. This genus appears nested within a large doryctine Neotropical clade as sister group of a cluster containing species of Callihormius Ashmead, Leluthia Cameron, Histeromeroides Marsh and Panama Marsh.

Phylogenetic relationships among the families in the infraorder Sejina and the position of Sejina relative to other infraorders of Mesostigmata are re-examined based on molecular and morphological data. Data sets included DNA sequence data for complete 18S, EF-1 , partial CO1genes, and 69 morphological characters. The two families of Heterozerconina consistently group within Sejina, and we propose to synonymize Heterozerconina with Sejina (Sejina s.l). Microgyniina is not the closest relative of Sejina. Rather, Sejina s.l. most often groups with Gamasina. Uropodellidae and Ichthyostomatogasteridae are sister groups and this lineage forms the sister group to Discozerconidae plus Heterozerconidae. Overall, we recognize 5 families within Sejina: Uropodellidae, Ichthyostomatogasteridae, Sejidae, Discozerconidae, and Heterozerconidae.

First Time

The fern genus Tectaria has generally been placed in the family Tectariaceae or in subfamily Tectarioideae (placed in Dennstaedtiaceae, Dryopteridaceae or Polypodiaceae), both of which have been variously circumscribed in the past. Here we study for the first time the phylogenetic relationships of the associated genera Hypoderris (endemic to the Caribbean), Cionidium (endemic to New Caledonia) and Pseudotectaria (endemic to Madagascar and Comoros) using DNA sequence data. Based on a broad sampling of 72 species of eupolypods I (= Polypodiaceae sensu lato) and three plastid DNA regions (atpA, rbcL and the trnL-F intergenic spacer) we were able to place the three previously unsampled genera. Our results show that Cionidium, like Ctenitopsis, Fadyenia, Hemigramma and Quercifilix, is embedded in Tectaria, and the monophyly of Tectaria is therefore corroborated only if these segregate genera are included. Hypoderris is sister to Tectaria brauniana and together they are sister to Triplophyllum, which was found to be monophyletic. Despite their morphological similarity with Tectaria, the genera Pleocnemia and Pseudotectaria were placed in Dryopteridoideae. Polypodiaceae subfamily Tectarioideae (former family Tectariaceae) is hereby defined to include Arthropteris, Hypoderris, Pteridrys, Tectaria and Triplophyllum. Aenigmopteris may also belong here, but this genus remains unsampled.

A cladistic analysis of relationships among the genera of Scorpionidae Latreille, 1802—Heterometrus Ehrenberg, 1828; Opistophthalmus C. L. Koch, 1837; Pandinus Thorell, 1876; and Scorpio Linnaeus, 1758—based on morphology and DNA sequence data from loci of three genes in the mitochondrial genome (12S ribosomal DNA (rDNA), 16S rDNA and cytochrome oxidase I) and one gene in the nuclear genome (28S rDNA) is presented. The analysis makes use of exemplar species, specifically selected to test the monophyly of the genera, rather than supraspecific terminal taxa. Other methods used in the analysis are justified in the context of a discussion of current methods for phylogenetic reconstruction. Relationships among the scorpionid genera are demonstrated to be as follows: (Opistophthalmus (Scorpio (Heterometrus + Pandinus))). This reconstruction identifies Opistophthalmus as the basal lineage of the Scorpionidae, rather than the sister-group of Scorpio. Revised descriptions, diagnoses and a key to identification of the four scorpionid genera are provided, together with a summary of what is known about their ecology, distribution and conservation status.
