We report three new species of the ant genus Leptanilloides from Andean Ecuador. Leptanilloides nomada sp. n. and L. caracola sp. n. are described from the worker caste, the latter from a unique specimen; L. nubecula sp. n. is described from workers, males, and two gyne subcastes previously unknown for the entire subfamily. Phenotypic variation in morphological characters in the new species L. nomada and L. nubecula is more plastic than suggested by the traditional generic diagnosis. These records represent the first case of three Leptanilloides species occurring in sympatry. We discuss aspects of the army ant syndrome and its relevance to the genus Leptanilloides.Tres nuevas especies del género de hormigas Leptanilloides son descritas a partir de especimenes encontrados en Los Andes ecuatorianos. Leptanilloides nomada sp. n. y L. caracola sp. n. son descritas en base a obreras, ésta última es descrita a partir de un sólo espécimen. L. nubecula sp. n. es descrita en base a obreras, machos y dos subcastas de ginas previamente desconocidas para toda la subfamilia. La variación fenotípica encontrada en algunos caracteres morfológicos de las nuevas especies L. nomada y L. nubecula es más plástica de lo que sugiere la diagnosis genérica tradicional. Estos registros constituyen el primer ejemplo de tres especies de Leptanilloides viviendo en simpatría. Discutimos aspectos del síndrome de las hormigas legionarias y su aplicación al género Leptanilloides.

Three New Species

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.

Neomuscina Townsend includes 41 species distributed throughout the Nearctic and Neotropical Regions. Although the genus has a large number of species, it has been ignored and its taxonomy is confusing and has many flaws. In this work we analyzed the following species recorded for Brazil: Neomuscina atincta Snyder, N. atincticosta Snyder, N. capalta Snyder, N. currani Snyder, N. douradensis Lopes & Khouri, N. goianensis Lopes & Khouri, N. inflexa (Stein), N. instabilis Snyder, N. mediana Snyder, N. mimosa Lopes & Khouri, N. neosimilis Snyder, N. nigricosta Snyder, N. paramediana Lopes & Khouri, N. pictipennis pictipennis (Bigot), N. ponti Lopes & Khouri, N. sanespra Snyder, N. schadei Snyder, N. similata Snyder, N. stabilis (Stein), N. transporta Snyder, N. vitoriae Lopes & Khouri and N. zosteris (Shannon & Del Ponte). Neomuscina nigricosta and N. transporta are new distribution records for Brazil. Three new species are described: Neomuscina anajeensis sp. nov. from Anagé (Bahia), Neomuscina maculata sp. nov. from Botelhos (Minas Gerais) and Neomuscina snyderi sp. nov. from Mata de São João (Bahia). An identification key based on the morphological characters of both male and female is provided. Species distributions are discussed and updated, and the number of species now recorded for Brazil is 29.

Lung flukes of the genus Haematoloechus Looss, 1899 are common parasites of anurans worldwide, but the taxonomy of the group has been confusing. In this taxonomic revision, 89 species of Haematoloechus (= Pneumonoeces Looss, 1902, Ostioloides Odening, 1960, Ostiolum Pratt, 1903, Skrjabinoeces Sudarikov, 1950, Neohaematoloechus Odening, 1960, Metahaematoloechus Yamaguti, 1971) are listed. Of these, 70 are considered valid, three are species inquirendae (H. legrandi Mañé–Garzón & Gil, 1959, H. latoricensis Kozák, 1968 & H. vitelloconfluentum (Rai, 1962) Saeed, Al–Barwari & Al-Harmni, 2007), one is a nomen nudum H. sudarikovi Belouss, 1962, 14 are junior synonyms and one belongs to Ostioloides. This publication also describes three new species, H. occidentalis n. sp., H. veracruzanus n. sp. and H. mexicanus n. sp., parasitizing species of Rana Linnaeus in Mexico and redescribes Haematoloechus caballeroi (Skrjabin & Antipin, 1962) Yamaguti, 1971. The phylogenetic hypotheses based on sequences of mitochondrial and ribosomal DNA of Haematoloechus spp. show that genera proposed on the basis of morphological characters are not supported. The host records for species of Haematoloechus, together with the phylogenetic hypothesis of the genus, suggest that this host-parasite association predates the ranid diversification in the Cretaceous.

We review species of Parodon Valenciennes, 1850 from the Magdalena, Cauca, Orinoco, Amazonas, Atrato and Caribbean-Guajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previously described: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upper Amazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibo basin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from the middle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodon suborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification of the species, as well as geographic distribution maps.

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.

The Cryptini Eknomia Santos et Aguiar gen. nov. is proposed, described, and cladistically compared with representativespecies of 40 outgroup genera from twelve cryptine subtribes. A total of 98 morphological characters were evaluated. Allanalyses, conducted in TNT under implied and equal weighting, clearly suggest that Eknomia is a monophyletic groupand can be treated as a distinct genus. Its likely sister group, however, varied among different analyses and could not beascertained. The relationships of the new genus are therefore unclear, and because of this it is not assigned to any of thecurrently recognized subtribes. Eknomia can be diagnosed mainly by the anterior transverse carina of propodeum entirelyabsent; propodeum more or less uniformly strigate; clypeus almost entirely flattened; ovipositor stout, with compressed,minutely serrate flange at apex of dorsal valve, subapically crossed by a subvertical line; first metasomal spiracle placedat tergite midlength or nearly so; and hind margin of metanotum with tooth-like projections. The species E. nigra Santoset Aguiar, sp. nov., E. rubra Santos et Aguiar, sp. nov. and E. propodeator Santos et Aguiar, sp. nov. are described and illustrated. The genus is recorded from Colombia to southern Brazil.
