A New Species

We describe a new genus, Gracilidris Wild & Cuezzo gen. nov., and a new species, G. pombero Wild and Cuezzo sp. nov., of dolichoderine ants (Hymenoptera: Formicidae: Dolichoderinae) from Paraguay, Brazil and Argentina based on the worker caste. These ants are morphologically similar to the extinct Gracilidris humilioides (Wilson 1985) comb. nov., known from a single Dominican amber fossil, that we redescribe and transfer to Gracilidris from Linepithema Mayr.

A New Species

Masona popeye Quicke & Chaul sp. n. is described from Brazil, and differentiated from other species of the genus. Described extant species of Masona are known from Australia and south eastern U.S.A. (Georgia and Florida including the Key Islands). Two undescribed species are known from Tanzania and Cambodia. The new species is therefore the first representative of the subfamily Masoninae van Achterberg from South America, demonstrating the completely cosmopolitan distribution of this very poorly known group. The new species most closely resembles a fossil species, M. pyriceps van Achterberg, 2001, from Dominican amber with which it shares the plesiomorphic presence of a scutellum.

AbstractElectroborus brighti, new genus, new species (Coleoptera: Curculionidae: Scolytinae) is described based on two specimens from Dominican amber, which represents the first Hylesinini found in Dominican amber. A phylogenetic analysis of 24 Hylesinini species and a Strombophorus Hagedorn species based on morphological characters suggests E. brighti is not related to the Neotropical genus Phloeoborus Erichson, but shares a close affinity to African Hylesinini genera. The discovery of this new genus adds to the evidence that tropical South America and Africa shared similar faunas throughout evolutionary history. Although many Old World taxa have become extinct in the New World, the existence of E. brighti among Recent faunas is a possibility, given that the South American and African scolytine faunas are relatively poorly studied.

The need for revision of related group Eustictus and a comprehensive study of its tribal placement within Deraeocorinae are discussed.

A New Species

A new genus, Drepanoneura (type species Drepanoneura loutoni sp. nov.), is described to include Epipleoneura letitia Donnelly, Protoneura peruviensis Fraser, and six new congeneric species from South America: D. donnellyi, D. flinti, D. janirae, D. loutoni, D. muzoni, and D. tennesseni. Drepanoneura is similar to Epipleoneura and Epipotoneura in venational characters, but differs from them in morphology of male cercus, genital ligula, female pronotum, and epiproct. A new species of Epipleoneura from Venezuela, E. demarmelsi, and a new species of Epipotoneura from Brazil, E. machadoi, are described, and diagnostic illustrations for the poorly known Epipotoneura nehalennia Williamson are also presented. A generic characterization, diagnoses, and keys for species of Drepanoneura are provided, as well as diagnostic illustrations and distribution maps for all involved species.

A New Species

The genusColombocarisis proposed for a new species discovered on submerged mosses of a high Andean lake in Colombia. The diagnostic characters of the genus mainly concern the morphology of legs, particularly the endopod of leg 2, leg 3, the endopodite of leg 4 and the peculiar leg 5, the cuticular windows of body segments and the morphology of the furca. The new genusNoodtcarisis proposed for three species of theParastenocaris columbiensis-group, viz.,P. columbiensis,P. kubitzkiiandP. roettgeri, described from the Colombian Llanos Orientales, and forP. tapajosensisfrom the Brazilian Amazonas. This genus is well defined by the ornamentation of the caudal rami and the morphology of legs 2 to 5. The absence of endopod on female leg 3 is a diagnostic character at least for the Colombian species. A key for the identification of the species composing the new genera is provided.

Dominican amber is the fossil resin famous for the best quality of inclusions, exploited in Dominican Republic from the deposits formed in the late Early Miocene, ca. 16 Ma. A new species, Polymera (Polymera) alexanderi sp. n. of the dipteran family Limoniidae is described from this amber. This new limonid belongs to the genus Polymera Wiedemann, 1820 with 63 extant species described mostly from South America. Only three fossil species are known so far from Dominican and Baltic amber.

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.
