An overview of the taxa of Rhinorhynchinae (Nemonychidae) is presented. A phylogenetic analysis of the 19 extant genera of the Rhinorhynchinae and one fossil genus from the Lower Cretaceous (Cratomacer Zherikhin & Gratshev), based on 29 characters of adults, larvae and host plant associations, shows three monophyletic groups, treated as tribes (Rhinorhynchini, Mecomacerini and Rhynchitomacerini). Primitive associations are unknown for Rhinorhynchinae and early host use diversification included associations with Ranunculaceae (Nemonyx Redtenbacher), Pinaceae (Cimberis Gozis), Nothofagaceae (Rhynchitomacerini) and Podocarpaceae (Rhinorhynchini). While Mecomacerini diversified on Araucariaceae, within Rhinorhynchini there was a single reversal to Araucariaceae and a shift in Atopomacer Kuschel to Pinaceae. Placement of Cratomacer into Mecomacerini is consistent with geological and molecular data that suggest gymnosperms may have been the primitive hosts for the family. Three new genera are described in Rhinorhynchinae: Araucomacer, gen. nov. (type species A. hirticeps Kuschel) from Chile, Idiomacer, gen. nov. (type species I. basicornis, sp. nov.) from New Caledonia, and Zimmiellus, gen. nov. (type species Z. fronto, sp. nov.) from Queensland, Australia, while Stenomacer Kuschel, stat. nov. from Chile is reinstated from synonymy. Seven species are described as new: Atopomacer grandifurca, sp. nov. from Costa Rica and Panama, A. obrieni, sp. nov. from Mexico, A. panamensis, sp. nov. from Panama, A. pini, sp. nov. from Mexico, A. podocarpi, sp. nov. from Venezuela, Basiliogeus dracrycarpi, sp. nov. from western New Guinea and B. inops, sp. nov. from Queensland. Rhynchitomacer rufus Kuschel is a new junior subjective synonym of R. nigritus Kuschel, syn. nov., R. viridulus Kuschel is a new junior subjective synonym of R. flavus Voss, syn. nov. and Stenomacer fuscus Kuschel is a new junior subjective synonym of S. vernus Kuschel, syn. nov. Keys to genera of Rhinorhynchinae and to species of Atopomacer, Rhynchitomacer and Stenomacer are included. Diagnoses of the three extant subfamilies of Nemonychidae are included.

This study represents the first phylogenetic reconstruction of lumbrinerid genera using parsimony analyses of 38 morphological characters. Following higher-level phylogenetic analysis, Oenone (Oenonidae) was selected as outgroup. The analysis was restricted to type species for each genus, yielded 24 equally parsimonious trees, which after successive weighting were reduced to one tree (CI= 0.7396). The topology of this tree revealed the separation of the family into four main clades: 1. Lysarete, 2. Arabellonereis, 3. Scoletoma, Lumbrineris, Hilbigneris gen. nov., Kuwaita, Lumbricalus, Sergioneris gen. nov. and Eranno, and 4. Abyssoninoe, Cenogenus, Lumbrinerides, Lumbrineriopsis, Augeneria, Loboneris gen. nov., Gallardoneris gen. nov., Helmutneris gen. nov., and Gesaneris gen. nov.; the position of Ninoe is unclear. A diagnosis of each genus is provided, including the description of six new genera and three new species. A key to lumbrinerid genera is included.

Abstract The freshwater fish genus Astyanax is one of the most diverse among the Characidae. The genus is defined by a combination of character states that are widely distributed in Characidae. In addition, the genus has the broadest geographical distribution in the family, being found in a great variety of environments of the Neotropical region. Although phylogenetic relationships were treated only partially, many authors agree that the genus is not monophyletic. In this contribution, we study the phylogenetic relationships of Astyanax in the context of the family Characidae, by combining morphological and molecular data. A total of 520 morphological characters, nine molecular markers and 608 taxa are analysed, of which 98 belong to Astyanax. According to our results, Astyanax is not monophyletic. We recovered species attributed to Astyanax in different subfamilies: Gymnocharacinae (including the type species), Stevardiinae and Tetragonopterinae. Among the species recovered in Gymnocharacinae, most (including the type species, the resurrected Psalidodon, and the new genus Andromakhe gen. nov.) were recovered in Gymnocharacini, while the remaining ones were recovered in Probolodini (transferred to Deuterodon or the new genus Makunaima gen. nov.).

The bryocorine genus Caulotops Bergroth (Miridae: Eccritotarsini), originally described to accommodate its only species C. puncticollis Bergroth, is shown not to be congeneric with all other species now included in the genus from North, Central, and northern South America. Consequently, four new genera are established for the following 20 species, including five new combinations and 14 species described as new: Agaveocoris n. gen. for Caulotops agavis Reuter (as the type species), n. comb.; C. barberi Knight, n. comb.; and C. distanti Reuter, n. comb. and the new species A. bimaculatus, n. sp.; A. barrerai, n. sp.; A. dimidiatus, n. sp.; A. marginalis, n. sp.; A. roseus, n. sp.; A. rostratus, n. sp.; A. schaffneri, n. sp.; and A. scutellatus, n. sp; Laterospinocoris, n. gen. for Caulotops cyaneipennis Reuter, new comb. (as the type species) and the new species L. mexicanus, n. sp.; Nigrotomocoris n. gen. for Caulotops nigrus Carvalho (as the type species), n. comb.; C. tibiopallidus Carvalho, n. comb.; and the new species N. keltoni, n. sp. and N. longirostris, n. sp.; and Schaffnerocoris, n. gen., for S. fuscotibialis, n. sp. (as the type species), S. pallipes, n. sp., and S. similis, n. sp. Lectotypes are designated for Caulotops agavis Reuter, Caulotops cyaneipennis Reuter, and Caulotops puncticollis Bergroth, and a neotype is designated for Eccritotarsus platensis Berg. Each genus and species is diagnosed and described; habitus images, illustration of male genitalia and selected female genitalia, and keys to genera and species are provided; and host use and the unique genitalic systems of these taxa are discussed. A phylogenetic analysis, based on 22 taxa and 39 characters, resulted in three trees supporting the monophyly of the four new genera proposed in this study.

(B. cola sp. n., B. samuelsoni sp. n.), Epelisentis gen. n. (E. celiae sp. n., E. gressitti sp. n.), Plikomiris gen. n. (P. freycinetiaphilus sp. n., P. monteithi sp. n.) and Torunotum gen. n. (T. badius sp. n., T. hystrix sp. n., T. oviformis sp. n., T. pindaii sp. n. and T. psydrax sp. n.), as well as Femurocoris madeleinensis sp. n., Montagneria yahouensis sp. n. Femurocoris Carvalho and Montagneria Akingbohungbe and their type species are redescribed, as is M. cuneatus (Distant). Stethoconus praefectus (Distant) is reported from Australia for the first time. A dichotomous key, illustrations of male genitalia, scanning electron micrographs and habitus photographs are provided. A phylogenetic analysis of a morphological dataset was undertaken resulting in a monophyletic Hyaliodini, and the New Caledonian hyaliodines form a subclade. A discussion of the infra-subfamilial classification of the Deraeocorinae is given.

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Abstract Bryozoans with calcified frontal shields formed by the fusion of costae, collectively constituting a spinocyst, are traditionally assigned to the family Cribrilinidae. Today, this family is regarded as nonmonophyletic. In the Argentine Cenozoic, cribrilinids were until recently represented by only two fossil species from the Paleocene of Patagonia. This study describes the first fossil representatives of Jolietina and Parafigularia: J. victoria n. sp. and P. pigafettai n. sp., respectively. A fossil species of Figularia, F. elcanoi n. sp., is also described. The material comes from the early Miocene of the Monte León and Chenque formations (Patagonia, Argentina). For comparison, we also provide redescriptions of the remaining extant species of Jolietina: J. latimarginata (Busk, 1884) and J. pulchra Canu and Bassler, 1928a. The systematic position of some species previously assigned to Figularia is here discussed. Costafigularia n. gen. is erected, with Figularia pulcherrima Tilbrook, Hayward, and Gordon, 2001 as type species. Two species previously assigned to Figularia are here transferred to Costafigularia, resulting in C. jucunda n. comb. and C. tahitiensis n. comb. One species of Figularia is reassigned to Vitrimurella, resulting in V. ampla n. comb. The family Vitrimurellidae is here reassigned to the superfamily Cribrilinoidea. The subgenus Juxtacribrilina is elevated to genus rank. Inferusia is regarded as a subjective synonym of Parafigularia. Parafigularia darwini Moyano, 2011 is synonymized with I. taylori Kuklinski and Barnes, 2009, resulting in Parafigularia taylori n. comb. Morphological data suggest that these genera comprise different lineages, and a discussion on the disparities among cribrilinid (sensu lato) spinocysts is provided.

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.

ABSTRACTThe systematics of parts of the Odontopleuridae are revised using character analyses tracing homologous structures, and a computerised cladistic analysis. The choice of outgroup is shown to affect the result of the analysis. Several synapomorphies place Selenopeltis, the type genus of the Selenopeltinae Hawle & Corda, 1847 as sister genus to Dicranurus. The latter's close relationship to Miraspis, type genus of the Miraspidinae Richter & Richter, 1917 is confirmed. The Selenopeltinae therefore becomes a senior subjective synonym of the Miraspidinae. The Selenopeltinae includes about 90 of the over 380 named odontopleurid species known to date (excluding accepted synonyms). The Ceratocephalinae is recognised, including about 30 species. The paired, large pygidial border spines present in most odontopleurids are in some species not homologous, and a falsifiable hypothesis is proposed for the homology of the ‘true major border spines’. This structure is the posterior pleural spine of the tenth postcephalic segment in selenopeltines, ceratocephalines and odontopleurines, and in acidaspidines and apianurines it is the serially homologous spine of the eleventh postcephalic segment. The spine belongs to the first pygidial segment in all taxa except ceratocephalines, where it is on the last thoracic segment. The homology in selenopeltines of the progressive restructuring of the cheek border is reviewed, explaining the supramarginal appearance of the genal spine. The presence and homology of the sublobation of L1 in odontopleurids is discussed, and it may be homologous with the sublobation in lichids. The strongly differentiated thoracic segmental lengths (exsag.), with maximum length reached in the anterior part of thorax, and the much reduced length of the posterior segments, are aspects of a single character-complex, uniquely derived within the Selenopeltinae. The ontogenetic origin of the anterior and posterior pleural spines is reviewed. The presence in Ceratocephala of two instars in one meraspid degree is discussed. A cladistic analysis of selenopeltine and ceratocephaline genera does not entirely resolve the topology of the phylogenetic tree of these taxa, but it confirms Selenopeltis as sister taxon to Dicranurus. These two genera belong in a clade also including Miraspis, Selenopeltoides, and Ceratonurus. Two new genera are erected, Ceratocara and Archaeopleura, the latter with type species A. kazakhensis sp. nov.

Three new species of Chrysomelidae with extraordinary extensions of the male mandibles are described: Scaphodius drehu sp. nov. and S. ferox sp. nov. (Cryptocephalinae), from New Caledonia, and Chaloenus gajah sp. nov. (Galerucinae), from Borneo. Designation of the type species of Chaloenus Westwood, 1861, is clarified. Synonymy of Scaphodius Chapuis, 1874, with Nyetra Baly, 1877, is supported. Four species of Ditropidus Erichson, 1842, described from New Caledonia, but hitherto regarded as nomina nuda, are shown to be available and are placed in Scaphodius: S. aeneus (Fauvel, 1907), comb. nov., S. nitidus (Fauvel, 1907) comb. nov., S. striolatus (Fauvel, 1907) comb. nov., S. sulcatus (Fauvel, 1907) comb. nov. Ditropidus opacicollis Fauvel, 1907, is also transferred to Scaphodius, as S. opacicollis (Fauvel) comb. nov. The genus Ditropidus does not occur onNew Caledonia. Male mandible enlargment in the Chrysomelidae is reviewed: it is common in Cryptocephalinae, but otherwise restricted to a few species of Chrysomelinae, Eumolpinae and Galerucinae. Possible reasons for its distribution in the Chrysomelidae are discussed.

Girardia Ball, 1974 is the most diverse and widely distributed genus of the family Dugesiidae (Platyhelminthes: Continenticola) in the Neotropical region. Seven out of the 52 species of the genus are known for Argentina. The Somuncurá Plateau is a region in northern Patagonia with several endemic flora and fauna, but little is known about the free-living Platyhelminthes. We describe two new species of Girardia partially inhabiting in sympatry in the Somuncurá Plateau: Girardia somuncura sp. nov. and Girardia tomasi sp. nov. The identification criteria that we followed was an integrative taxonomic approach based on morphological and molecular data. Thus, we used anatomical features focused on the reproductive system, together with a phylogenetic analysis, using a mitochondrial (COI barcode region) genetic marker. This study is the first phylogenetic analysis of the genus Girardia in which we include the southernmost representatives of America here described, thus making it possible to incorporate them in global phylogenies.
