Two New Species

The Hydrophilus (Dibolocelus) Bedel species from Mexico and adjacent areas are treated on the basis of the study of 142 adult specimens and published data. Two new species are herein recognized and described: H. (D.) nucleoensis Arce-Pérez & Arriaga-Varela sp. nov. from Mexico, Guatemala and Nicaragua, H. (D.) pseudovatus Arce-Pérez & Arriaga-Varela sp. nov. from Mexico. Three already known species are re-described and their geographical distribution is updated, H. (D.) ovatus Gemminger & Harold and H. (D.) pollens Sharp and H. (D.) violaceonitens Jacquelin du Val, a species resurrected as distinct to H. (D.) smaragdinus. Hydrophylus (D.) cf. purpurascens (Régimbart) is also redescribed but their identity is questionable. The lectotype of H. (D.) pollens Sharp is designated. Within Mexico, the state with the highest known diversity is Veracruz with five species. A key to the species of Hydrophilus (Dibolocelus) from Mexico and Central America is provided.

Twenty six species of Scaphopoda, included in 12 genera and five families were identified. Within these, Fustiaria stenoschiza (Pilsbry & Sharp, 1897), Gadila pocula n.comb. (Dall, 1889); G. simpsoni n.comb. (Henderson, 1920) and G. pandionis (Verril & Smith in Verril, 1880) are recorded for the first time for Brazil and two new species of the genus Cadulus are here described. Besides that, six species previously recorded from north and northeast Brazil have their geographical range expanded southward: Antalis circumcincta (Watson, 1879), Episiphon didymum (Watson, 1879), Ep. sowerbyi (Guilding, 1834), Entalina platamodes (Watson, 1879), Gadila dominguensis (Orbigny, 1853) and Compressidens pressum (Pilsbry & Sharp, 1897). In the other hand, Paradentalium infractum n.comb. (Odhner, 1931) has its geographical distribution extended northward to the state of Maranhão (02ºS). Gadila acus (Dall, 1889) is proposed as junior synonym of G. dominguensis (Orbigny, 1853).

Two New Species

We present an overview of the morphological diversity and geographical distribution of the anostracan genus Dendrocephalus Daday, 1908, and describe two new species: D. aranai sp. nov. from Jequitinhonha in the state of Minas Gerais and D. xikrini sp. nov. from the Carajás Mountains (Serra dos Carajás) in the state of Pará. These species have important similarities to D. goiasensis Rabet & Thiéry, 1996 and D. thieryi Rabet, 2006, respectively, but differ from them and each other through a combination of characters that are essentially unique to the endopods, and frontal appendage branch 2A and branch 2D. We also partly redescribe D. carajaensis Rogers, Gomes & Vieira, 2012, which shows a particular intra-populational variability in branch 2A and 2D III of the frontal appendage, a type of polymorphism that was also recently observed in D. orientalis Rabet & Thiéry, 1996 and which must now be taken into account in taxonomy. In terms of the distribution of species of Dendrocephalus in Brazil, we suggest that several other species are probably present in the Amazonian, Cerrado and Pantanal Biomes, which remain largely unexplored. A new taxonomic key for the identification of males of the Brazilian species is provided.

The oscinelline genus Medeventor Wheeler, 2007 was originally proposed for a single quite aberrant species from Central America, M. nubosus Wheeler, 2007. In this paper, we present two new Brazilian species of Medeventor—M. minimus sp. n. and M. tschirnhausi sp. n. (both from the State of Mato Grosso). A key for the species of the genus is provided. Some comments are made on the diagnosis of the genus.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Cryptic Taxa

More than ten new species of colonial volvocine algae were described in world literature during recent years. In present review, the published data on taxonomy, geographical distribution and the species problem in this group of algae, mainly from the genera Gonium, Pandorina, Eudorina, and Volvox, are critically discussed. There are both cosmopolitan volvocalean species and species with local or disjunct distribution. On the other hand, the description of new cryptic taxa in some genera of the colonial family Volvocaceae, such as Pandorina and Volvox, complicates the preparation of a comprehensive review on their geography.

Two New Species

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

Two New Species

Since the publication of the previous paper (Leeson, 1953), additional information has been accumulated on the geographical distribution of some of the Old World ticks of the genus Ornithodoros and two new species (zumpti and arenicolous) have been described. Much of this additional matter has been communicated to me by correspondents who have been kind enough to give permission for its publication here. Their names are enclosed in brackets after the new data to indicate the source and to these workers I tender my sincere thanks.
