The present study proposed a phylogenetic hypothesis of the family Fanniidae based on a cladistic analysis using characters from adult external morphology and female and male terminalia. The main purpose of this study was to clarify the phylogenetic position of newly described or poorly known species, mostly from southern South America, the Neotropics, Africa, Australia and New Zealand. In total, 151 characters from adult male and female external morphology and terminalia were scored for 78 species of Fanniidae. Ten continuous characters were included and analysed as such. Three genera of Fanniidae and all the species-groups and subgroups proposed for the genus Fannia, except for the admirabilis-group and the setifer-subgroup were included as terminal taxa. An heuristic parsimony analysis under implied weights was performed. The analysis recovered the monophyly of the Fanniidae and the genus Fannia, as well as the monophyly of several species-groups within Fannia. Male and female external morphological characters were, in general, highly homoplasious, whereas characters from male terminalia showed low level of homoplasy and provided resolution at suprageneric nodes and species-groups.

Phylogenetic relationships within the “symmetrical” hermit crab family Pylochelidae were analyzed for 41 of the 45 species and subspecies currently considered valid. In the analyses, 78 morphological characters comprised the data matrix and the outgroup consisted of Thalassina anomala, a member of the Thalassinidae, and Munida quadrispina, a member of the Galatheidae. A poorly resolved strict consensus tree was obtained from a heuristic parsimony analysis of unweighted and unordered characters, which showed the family Pylochelidae and the subfamilies Pylochelinae and Pomatochelinae to be monophyletic taxa – the latter two groups had the highest Bremer support values. Additionally, while the subgenus Pylocheles (Pylocheles) was strongly supported, the subgenera Xylocheles, and Bathycheles were not. More fully resolved trees were obtained when using implied weighting, which recognized the monotypic subfamilies Parapylochelinae, Cancellochelinae and Mixtopagurinae. The subfamily Trizochelinae was found to have four distinct clades and several ambiguously placed taxa.

A cladistic analysis of the Empidoidea and basal lineages of the Cyclorrhapha, based on morphological characters, confirms the monophyly of both groups as well as that of the                    Eremoneura. The resulting final trees are used to revise the classification of the Empidoidea to include the following five families: Empididae, Hybotidae, Atelestidae (including Nemedininae n. subfam.), Brachystomatidae rev. stat. (comprising the subfamilies Brachystomatinae, Ceratomerinae and Trichopezinae), and Dolichopodidae s.lat. The family Microphoridae is not recognized, and the Microphorinae and Parathalassiinae are assigned to the Dolichopodidae s.lat. The Dolichopodidae s.str. includes 15 subfamilies that were previously recognized within the family. Within the Empidoidea we found support for Atelestidae as the sister group to the Hybotidae and for the monophyly of Parathalassiinae + Dolichopodidae s.str. The Empididae remains poorly defined and the genera Homalocnemis Philippi, Iteaphila Zetterstedt, Anthepiscopus Becker, and Oreogeton Schiner are classified as incertae sedis within the                   Empidoidea. In addition, the following higher taxa are proposed: Symballophthalmini n. tribe, Bicellariini n. tribe, Oedaleinae rev. stat., and Trichininae rev. stat., which are all assigned to the Hybotidae. The genus Sematopoda Collin is tentatively assigned to Trichopezinae, and Xanthodromia Saigusa is transferred from Hemerodromiinae to Brachystomatinae.        All morphological characters are extensively discussed and illustrated, including details of the antennae, mouthparts, internal thoracic structures, wings, and male and female terminalia. In addition, a key to families and unplaced genus groups of the Empidoidea is provided. Feeding habits are also discussed in terms of the empidoid ground plan condition.

The genus Metania comprises 11 species of freshwater sponge that are distributed circumtropically: five are Neotropical, three Afrotropical, two Oriental and one Australian. Here we infer the phylogeny of the genus Metania and examine the processes that lead to the current biogeographic distribution using cladistic analysis. One matrix with 26 morphological characters was analysed using the TNT software, and resulted in two most parsimonious cladograms (strict consensus). Our results support monophyly of Metania due to two characters unique to the genus: presence of acanthoxeas and presence of spines in the shaft of the gemmoscleres. Also, the genera Drulia and Houssayella were synonymised with Metania. The family Metaniidae – allocated in the recently proposed order Spongillida – now contains three genera: Acalle Gray, 1867, Metania Gray, 1867 and Corvomeyenia Weltner, 1913. Brooks parsimony analysis of Metania resulted in a single area cladogram showing a Gondwanan pattern: (Neartic (Australian (Oriental (Afrotropical, Neotropical)))) and thus the current distribution is explained by the breakup of Gondwana.

Anatopynia vittigera Edwards is transfered to Alotanypus. The male and female of A. vittigera comb. nov. are redescribed and immatures are described and illustrated. A cladistic analysis including one species of each Macropelopiini genus was conducted in order to assess the phylogenetic position of Alotanypus and to provide the first phylogenetic hypothesis for the genus. Adults and immatures were included in the analysis where discrete and continuos characters were considered. The cladistic analysis demonstrated that Alotanypus is a monophyletic genus, with Guassutanypus oliveirai as the sister group.

Abstract Gripopterygidae is a diverse family of stoneflies, Plecoptera, distributed in the Southern Hemisphere. It has been traditionally divided into five subfamilies, but the monophyly of most of these is not supported by molecular the more comprehensive molecular analysis of the order. To test the monophyly of Antarctoperlinae, and to establish the phylogenetic position of a new Gripopterygidae species, we performed a morphological cladistic analysis including 38 morphological characters and 27 terminal taxa, with representatives of the four subfamilies present in South America and three Austroperlidae. Based on published information, we rooted the tree with Penturoperla barbata, Austroperlidae. As a result, Antarctoperlinae was recovered as polyphyletic, with Vesicaperla kuscheli and Plegoperla punctata, two members of the subfamily, placed outside the clade that includes the nine remaining genera of Antarctoperlinae. Vesicaperla also falls outside the family in previous molecular analysis. Based on this evidence, it should not be placed in Antarctoperlinae. Plegoperla punctata, known only from the type series, possesses many missing entries in our data matrix. Based on this, it seems convenient to maintain its subfamilial placement. In the tree obtained, the potential new species nests together with Pehuenioperla llaima. We thus accept it as a member of Pehuenioperla and describe it as P. microptera sp. nov.

A New Species

Plant bugs, species of Miridae (Heteroptera), are not well known in the Neotropics, and Colombia is not an exception. Based on data from the available systematic catalog (Schuh 2002–2013) fewer than 150 species are recorded from the country, clearly an underestimation. Recent fieldwork has resulted in several new interesting taxa from Colombia. Carvalhomiris Maldonado & Ferreira, 1971, contains three described species from Colombia and Ecuador. From specimens collected in Jardín, Antioquia, Carvalhomirishenryisp. n. is described. Images of the dorsal habitus and the male and female genitalia are provided. Based on morphological examination of the new species and published information, morphological characters were coded to construct a phylogenetic matrix for a cladistic analysis in which the phylogenetic position of the new species is assessed. Carvalhomirishenryisp. n. is the northernmost species of the genus and noteworthy because it is the first record of any species of the genus in the Western Cordillera: all other species are known from the eastern flank of the Andes (Ecuador) or the Eastern Cordillera (Colombia). Natural history observations of the new species, including associations with composites (Asteraceae) are provided. It is speculated that the mirid might be predacious.

Three New Species

Abstract The family Polymitarcyidae, with a worldwide distribution, includes mayflies with large burrowing nymphs. South America harbors the highest diversity of this family, including the subfamilies Asthenopodinae and Campsurinae. In this work, three new species belonging to the genera Tortopsis and Tortopus (Campsurinae) are described based on adults and nymphs from Colombia: Tortopsis torosp. nov., Tortopsis andakisp. nov. and Tortopus coreguajesp. nov. Additionally, Tortopsis limoncocha is firstly recorded from Colombia. A cladistic analysis of all the species in these genera is presented, using external morphological characters of adults and eggs. Keys to male and female adults of all the species of both genera are presented.

This study provides new and additional data on morphology and a phylogenetic analysis of the recently described species Pelagia benovici Piraino, Aglieri, Scorrano & Boero, 2014 from the Northern Adriatic (Mediterranean Sea). Comprehensive morphological analyses of diagnostic characters, of which the most significant are marginal tentacles anatomy, basal pillars, gonad pattern, subgenital ostia and exumbrellar sensory pits, revealed significant differences from the currently known genera Sanderia, Chrysaora and Pelagia in the family Pelagiidae. A phylogenetic analysis of mitochondrial genes (COI, 16S rRNA, 12S rRNA) and nuclear ribosomal genes (28S rRNA, ITS1/ITS2 regions), together with cladistic analysis of morphological characters, positioned Pelagia benovici as a sister taxon with Sanderia malayensis, and both share a common ancestor with Chrysaora hysoscella. Pelagia benovici does not share a direct common ancestor with the genus Pelagia, and thus we propose it should not belong to this genus. Therefore, a new genus Mawia, gen. nov. (Semaeostomeae : Pelagiidae) is described, and Pelagia benovici is renamed as Mawia benovici, comb, nov.

A phylogenetic analysis of the species belonging to the weevil genus Rhinusa Stephens, 1829 (Coleoptera: Curculionidae: Curculioninae: Mecinini) was carried out. Rhinusa weevils feed on plants of the closely related families Scrophulariaceae and Plantaginaceae. Based on a cladistic analysis of six outgroup and 33 ingroup taxa, and 39 adult morphological and 8 ecological characters, eight well supported species groups and two monobasic groups belonging to three separate and more inclusive assemblages were recognized. The first assemblage (A) includes nine species belonging to two groups (R. bipustulata and R. tetra groups), whereas the second and third assemblages (B and C) include a total of 14 species belonging to two groups (R. antirrhini and R. linariae groups) and six groups (R. pilosa, R. herbarum, R. neta, R. vestita, R. mauritii and R. melas groups), respectively. Two of the three main assemblages (A and B) are well supported as monophyletic entities, whereas the third assemblage (C) has weak support contingent in part upon the exclusion of host plant associations. Assemblage A includes all species living on species of Scrophulariaceae, with two groups occurring on two closely related plant genera, Scrophularia (R. bipustulata group) and Verbascum (R. tetra group), respectively. The other two assemblages include species living exclusively on species of the family Plantaginaceae, tribe Antirrhineae. These patterns suggest a well conserved and phylogenetically congruent association among the weevils and their hosts. Optimizing host plant preferences onto the morphological phylogeny indicates that feeding on Plantaginaceae was the plesiomorphic condition for the genus Rhinusa. In general there are no strict relationships between groups of weevils and their specific feeding habits; however, species of the R. antirrhini group are all feeding on seed capsules. In contrast, in other groups the larvae of closely related species display significant variations in host plant parasitism. Some species of the R. tetra group feed on seed capsules whereas others are stem borers. In turn, certain species of the R. neta group feed on seed capsules yet others are inquilines of gall forming species of Rhinusa. The latter habit is present in multiple convergent groups such as the R. linariae and R. pilosa groups.

New Material

New Oriental taxa of the Lygistorrhinidae - Blagorrhina gen. n., with B. blagoderovi sp. n. and B. brevicornis sp. n.; Gracilorrhina gracilis gen. n., sp. n.; and Labellorrhina gen. n., with L. grimaldii sp. n. and L. quantula sp. n. are described, and two undescribed species, known only from females, are characterized. Based on this new material, the family is redefined. The phylogeneticrelationships among the taxa of Lygistorrhinidae were studied by parsimony analysis using 43 morphological characters from the adults of 25 ingroup and one outgroup species. The cladistic analysis produced 14 most parsimonious cladograms. The solution obtained suggests unambiguously the following phylogeny: Palaeognoriste Meunier and “Lygistorrhina” asiatica Senior-White are successively sister groups of the rest of the Lygistorrhinidae; there is a clade Labellorrhina + (Gracil- orrhina + (Blagorrhina + ((Seguyola Matile + (Loyugesa Grimaldi & Blagoderov + Matileola Papp))))) with a monophyletic Lygistorrhina Skuse – Probolaeus Williston lineage as sister group. The phylogeny among the latter group remains largely unresolved.
