Orientador: Prof. Dr. Rodney Ramiro CavichioliDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências Biológicas, Programa de Pós-Graduação em Ciências Biológicas. Defesa: Curitiba, 22/02/2013Bibliografia : fls. 58-63Área de concentração: EntomologiaResumo: Gerridae Leach, 1815 é composta por 75 gêneros e mais de 700 espécies, distribuídas em oito sub famílias: Charmatometrinae, Cylindrostethinae, Eotrechinae, Gerrinae, Halobatinae, Ptilomerinae, Rhagadotarsinae e Trepobatinae (sensu Andersen 1975). Cylindrostethinae é composta pelos gêneros Platygerris, Potamobates e Cylindrostethus (Hungerford & Matsuda 1960). As espécies de Cylindrostethus diferenciam-se facilmente dos demais gerrídeos por ser longas e cilíndricas (Drake & Harris 1952). Atualmente são registradas dezoito espécies, ocorrendo na região paleotropical e neotropical. Na América do Sul ocorrem nove espécies: C. bassleri Drake, 1952; C. bilobatus Kuitert, 1942; C. erythropus (Herrich - Schaffer, 1850); C. hungerfordi Drake & Harris, 1934; C. linearis (Erichson, 1848); C. palmaris Drake & Harris, 1934; C. podargus Drake, 1958; C. regulus (White, 1879) e C. stygius Drake, 1961. Foram estudados 285 espécimes, incluindo representantes das nove espécies registradas, com seus respectivos tipos, exceto de C. erythropus, que não foi encontrado. No presente trabalho, as espécies de Cylindrostethus Sul-americanas foram revisadas com base na morfologia externa, principalmente a genitália dos machos. A partir do exame do material, as espécies foram redescritas, descritas e ilustradas. Duas novas espécies foram descritas, C. stygius é sinonimizada com C. podargus, e C. linearis é sinonimizada com C. erythropus. São apresentadas chave de identificação, mapas, desenhos e fotos.Abstract: Gerridae Leach, 1815 is composed of 75 genera and more than 700 species, distributed into eight sub families: Charmatometrinae, Cylindrostethinae, Eotrechinae, Gerrinae, Halobatinae, Ptilomerinae, Rhagadotarsinae and Trepobatinae (sensu Andersen, 1975). Cylindrostethinae is composed of the genera Platygerris, Potamobates and Cylindrostethus (Hungerford & Matsuda 1960). Cylindrostethus species easily differ from other gerrids by being long and cylindrical (Drake & Harris 1952). Eighteen species have been currently registered in the Paleotropical and Neotropical region. Nine species occur in South America: C. bassleri Drake, 1952; C. bilobatus Kuitert, 1942; C. erythropus (Herrich - Schaffer, 1850); C. hungerfordi Drake & Harris, 1934; C. linearis (Erichson, 1848); C. palmaris Drake & Harris, 1934; C. podargus Drake, 1958; C. regulus (White, 1879) and C. stygius Drake, 1961. Were studied 285 specimens, grouped into the nine species recorded, with their respective types, except for C. erythropus, which was not found. This study aimed to revise the South American Cylindrostethus based on their external morphology, mainly on the male genitalia. From the examination of the material, the species were redescribed, described and illustrated. Two new species are describeds, C. stygius is synonymized with C. podargus and C. linearis is synonymized with C. erythropus. Identification key, maps, pictures and photos are presented

Revision and phylogeny of Cylindrostethinae (Insecta: Hemiptera: Gerridae)

A subfamília Cylindrostethinae agrupa os gêneros Cylindrostethus, Platygerris e Potamobates, e está distribuída na região Neotropical e Paleotropical. A monofilia da subfamília e dos gêneros precisam ser avaliados, e muitas das relações entre os gêneros e espécies permanecem desconhecidas. Por exemplo, recentemente a monofilia de Cylindrostethinae foi testada, no entanto, não foi corroborada. Neste contexto, no presente trabalho propusemos filogenias morfológicas para a subfamília e para os gêneros; adicionalmente fizemos uma revisão taxonômica de Platygerris e Potamobates. A tese inclui filogenias; comentários, descrições e redescrições de espécies (com ilustrações, fotos, imagens de microscopia de varredura); chaves de identificação e mapas. Como resultado taxonômico, duas novas espécies de Platygerris e uma de Potamobates foram descritas, e três espécies foram sinonimizadas C. meloi Floriano & Cavichioli, 2013 = C. bassleri Drake, 1952 e P. tumaquensis Padilla-Gil & Damgaard, 2011 = P. horvathi Esaki, 1926 e P. sumaco Cognato 1998 = P. williamsi Hungerford 1932. Foram feitas adaptações nas chaves de identificação para as espécies válidas dos gêneros e análise filogenética para testar a monofilia da subfamília e gênero e compreender as relações interespecíficas. Com exceção de Potamobates, a monofilia de todos os táxons foi corroborada, adicionalmente, um novo gênero foi descrito.The subfamily Cylindrostethinae comprises the genera Cylindrostethus, Platygerris and Potamobates, and occurs on Neotropical and Paleotropical regions. The monophyly of the subfamily and genera need to be evaluated, and many of the relationships among genera and species remain unknown. For example, recently, the monophyly of Cylindrostethinae was tested and was not corroborated. Thus, in this thesis, we proposed morphological phylogenies to subfamily and to genera; in addition, we did the taxonomic review of Platygerris and Potamobates. The thesis included phylogenies; comments, descriptions, and redescroptions of the species (with illustrations, photos, and scanning microscopy images); identification keys, and maps. As taxonomic results, we described two news species of Platygerris and one of Potamobates, and three species were synonimized C. meloi Floriano & Cavichioli, 2013 = C. bassleri Drake, 1952, P. tumaquensis Padilla-Gil & Damgaard, 2011 = P. horvathi Esaki, 1926 and P. sumaco Cognato 1998 = P. williamsi Hungerford 1932. We have adapted the identification Keys for valid species of genera, and we proposed phylogenies to test the monophyly of the subfamily and genera, and to understand interspecific relations. Except for Potamobates, the monophyly of all taxa was corroborated, in addition, we described a new genus

Revision of Potamobates Champion, 1898 (Hemiptera: Heteroptera: Gerridae) and description of a new genus for P. thomasi Hungerford, 1937.

Potamobates Champion, 1898 (Hemiptera: Heteroptera: Gerridae) heretofore included 18 species distributed from southern Mexico to Peru. They display a distinct morphology, especially regarding the projections of abdominal segment VIII. Specific identification and delimitation are difficult, and the genus lacks a thorough revision and evaluation of inter- and intraspecific variation. Here, we revise Potamobates, redescribe and/or illustrate known species, and describe P. molanoi Floriano and Moreira, sp. nov. and Brailovskybates Floriano and Moreira, gen. nov. The new genus is erected for P. thomasi Hungerford, 1937 and is characterized by the following features: (1) abdomen elongated, longer than the mesothorax; (2) abdominal spiracles positioned at the center of the segments; (3) male abdominal segment VIII without projections; (4) male pygophore and proctiger not rotated in relation to the longitudinal axis of the body; (5) female abdominal tergum VIII subequal in length and width; (6) and posterior margin of female abdominal sternum VII not produced medially, with a pair of lateral projections

Assis, SP, Brasil.Gerromorpha or semiaquatic bugs have the ability to walk on the surface of the water and occupy a wide variety of habitats. They are relatively well studied in the Neotropical Region, but some species are known only from the type localities or have many gaps in their documented distributions. In this study we examined specimens housed in the National Museum of Natural History, Smithsonian Institution, and report new records for 17 species: Mesovelia bila, Hydrometra argentina, H. caraiba, H. comata, Limnobatodes paradoxus, Euvelia lata, E. mazzucconiae, Husseyella turmalis, Oiovelia cunucunumana, Paravelia conata, Platyvelia brachialis, Steinovelia virgata, Halobatopsis platensis, H. spiniventris, Ovatametra obesa, Limnogonus aduncus aduncus, and L. recurvus
