Three New Species

The water scavenger beetle genus Tropisternus Solier, 1834, is one of the most common and recognizable taxa of aquatic beetles in the New World. As presently defined, the genus contains 60 species (Hansen 1999, Short & Hebauer 2006) and ranges from northern Canada to the southern tip of South America. The senior author (PJS) conducted a full revision of this taxonomically difficult genus for his PhD dissertation nearly fifty years ago (Spangler 1960). For the next several decades, PJS continued to update, revise, correct, and incorporate new material into this massive work. This paper makes available three new names of Tropisternus in preparation for the eventual publication of this authoritative treatment of the genus. It should be noted for those using the keys given in Spangler (1960) that the interpretation of some of the names proved incorrect following the examination of types; the key should be used with extreme caution particularly for Neotropical taxa.

Recent collecting efforts in the Neotropics have led to the discovery of numerous new species and lineages of aquatic beetles. Here, three new genera are described to accommodate fifteen new species of water scavenger beetles of the subfamily Acidocerinae from northern South America:Crucisternumgen. n.forC.escalerasp. n.(Venezuela),C.ouboterisp. n.(Guyana, French Guiana, Suriname, Venezuela),C.queneyisp. n.(French Guiana),C.sinuatussp. n.(Brazil),C.toboganensissp. n.(Venezuela),C.vanessaesp. n.(Suriname), andC.xingusp. n.(Brazil);Katasophistesgen. n. forK.charynaesp. n.(Peru),K.cuzcosp. n.(Peru),K.meridasp. n.(Venezuela) andK.superficialissp. n.(Ecuador); andNanosaphesgen. n.forN.castaneussp. n.(Brazil),N.hesperussp. n.(Suriname),N.punctatussp. n.(Guyana), andN.tricolorsp. n.(Guyana, Suriname). It was also found that the monotypic Neotropical endemic genusDieroxenusSpangler, 1979,syn. n.is congeneric withChasmogenusSharp, 1882 resulting in the single new combinationChasmogenuscremnobates(Spangler, 1979),comb. n..Katasophistesmeridasp. n.is known exclusively from seepage habitats, while the remaining taxa described herein are primarily associated with the margins of densely forested streams. Diagnoses, illustrations, distribution maps, and habitat summaries are provided for all new genera and species. A key to the genera of Acidocerinae of the New World is provided.

Elmidae is one of the most diverse families of aquatic beetles, with more than 1500 species in 151 genera. The Neotropical genus Portelmis formerly comprised five species known from Central and northern South America, divided into two species groups. Three new Brazilian species from the nevermanni group are described and illustrated here: Portelmis vanini sp. nov., Portelmis krolowi sp. nov. and Portelmis fusariae sp. nov. New species records for the North, Central-West and Southeast of Brazil are presented. We also provide first SEM images and an updated key for Portelmis species.

Three New Species

This study documents a comprehensive taxonomic treatment of the New World Ummidia species. At the onset of this work the genus comprised 27 species and one subspecies with a cosmopolitan distribution that includes North America, South America, Asia, northern Africa, and Europe; of these species the majority of the nominal diversity can be attributed to the New World where 20 species have been previously described. Ummidia oaxacana (Chamberlin, 1925) is considered a nomen dubium; U. tuobita (Chamberlin, 1917) and U. absoluta (Gertsch and Mulaik, 1940) are both considered junior synonyms of U. audouini (Lucas, 1835); the subspecies U. carabivora emarginata (Atkinson, 1886) is considered a junior synonym of U. carabivora (Atkinson, 1886); U. pygmaea (Chamberlin and Ivie, 1945) is considered a junior synonym of U. beatula (Gertsch and Mulaik, 1940); U. celsa (Gertsch and Mulaik, 1940) is considered a junior synonym of U. funerea (Gertsch, 1936); Hebestatis lanthanus (Valerio, 1987) is considered a junior synonym of U. rugosa (Karsch, 1880). Thirty-three new species are described: U. neilgaimani, U. gingoteague, U. rongodwini, U. okefenokee, U. richmond, U. macarthuri, U. colemanae, U. rosillos, U. mercedesburnsae, U. paulacushingae, U. waunekaae, U. gertschi, U. timcotai, U. gabrieli, U. pesiou, U. rodeo, U. huascazaloya, U. anaya, U. cuicatec, U. brandicarlileae, U. riverai, U. frankellerae, U. hondurena, U. yojoa, U. matagalpa, U. carlosviquezi, U. varablanca, U. quepoa, U. cerrohoya, U. quijichacaca, U. tibacuy, U. neblina, U. tunapuna.

AbstractThree new species of Tabanidae egg parasitoids are described: Telenomus hybomitraesp. nov. and Telenomus utilissp. nov., both reared from eggs of Hybomitra nitidifrons nuda (McDunnough) and Hybomitra lasiophthalma Macquart, and Telenomus chrysopsissp. nov., reared from eggs of Chrysops aestuans Wulp, Chrysops excitans Walker, and Chrysops mitis Osten Sacken. Specimens of these species were compared with type specimens of known New World species of scelionid parasitoids attacking tabanid eggs. Diagnostic characters and identification key to the Nearctic species are provided.

High Degree

The genus Cryphocricos Signoret, 1850 was recently determined in a molecular phylogeny to be distantly related to other taxa of the subfamily Cryphocricinae to the extent that it is now once again the sole member of the subfamily. This exclusively New World group of aquatic bugs lives in fast and usually turbulent current and respires by means of a plastron. Efforts to identify morphological features to distinguish among the species have largely fallen short, and some species have been established based on features that exhibit a high degree of intraspecific variation overlapping those of other species. Presented here is a review of the 13 described species with discussions of their features and photos of type specimens, and three new species from Venezuela and Colombia are described. Also presented is a diagnostic attribute unique to the enigmatic Cryphocricos barozzii Signoret, 1850.

A taxonomic revision of the flea beetle genus <em>Diphaulacosoma</em> Jacoby, endemic to Madagascar, is provided. This genus includes seven species of which three are new to science: <em>D. elegans</em> sp. n., <em>D. jenisi</em> sp. n., and <em>D. nigroscutis</em> sp. n. An updated catalogue including new material, new faunistic records, distributions, chorotypes, and ecological notes is supplied. Lectotypes for <em>Diphaulacosoma</em> <em>laevipenne</em> Jacoby, <em>D. bicolor</em> (Weise) and <em>D. scutellare</em> (Weise) are designated. Additionally, the revision comprises a key for the identification of all seven species considered, habitus photos, and microscope and scanning electron micrographs of diagnostic characters, including aedeagus and spermatheca.

The 35 previously described species (including 4 junior synonyms) of the New World erythroneurine leafhopper genus Zyginama are reviewed and descriptions are provided for 43 new species, 2 from U.S.A., 26 from Mexico, 1 from Panama, and 14 from the Amazon region of South America. The following new synonyms are recognized: Z. aucta (McAtee) equals Erythroneura bilocularis Van Duzee, syn. n., and E. inclita Beamer, syn. n.; Z. nicholi (Beamer) equals E. canyonensis Beamer, syn. n., and E. ales Beamer, syn. n. Separate keys are provided for identification of males from North and South America, all known species are illustrated, and data on their distributions are summarized. Phylogenetic analysis of 40 morphological characters of the 71 species for which males are known yielded a reasonably well resolved estimate of relationships among the included species, but branch support was low overall.

Three New Species

The study is based on new material from the collections of the Naturalis Biodiversity Centre in Leiden (RNHM) and the Hungarian Natural History Museum (HNHM) and addresses issues in two genera: Epeus Peckham & Peckham, 1886 and Ptocasius Simon, 1885 from Thailand. Both genera are of Asian/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of Epeus (Epeus daiqini sp. nov. (♂♀), Epeus pallidus sp. nov. (♀), Epeus szirakii sp. nov. (♀)) and two new species of Ptacasius (Ptocasius metzneri sp. nov. (♂♀) and Ptocasius sakaerat sp. nov. (♀)). Additionally, we redescribed E. tener (Simon, 1877) and added photographs of morphological characters. The genus Ptocasius is redefined due to the inclusion of 37 species, previously included in Yaginumaella Prószyński, 1979. Relationships and distribution of both genera are discussed in reference to molecular, morphological and distributional data, published by other authors in recent years.
