AbstractThe genus Paroaria is a group of conspicuous songbirds widely distributed in South America that has been studied recently to delimit its species and establish their phylogenetic relationships. Although hybridization has been reported between the most phylogenetically related species of the genus, we here present a case of hybridization between the Yellow-billed Cardinal (P. capitata) and Red-crested Cardinal (P. coronata) for the first time, two phylogenetically unrelated members of the group. This data contributes to the knowledge of this avian group whose systematics is still under debate.

AbstractA preliminary study of the Lecanora dispersa group in Argentina is presented. Two species (L. dispersa and L. hagenii) have been previously recorded and their known distribution is extended, one species (L. semipallida) is a new record from Argentina, and five taxa (L. flowersiana, L. persimilis L. torrida, L. wetmorei and L. zosterae var. zosterae) are reported for the first time from South America. Three species (L. albescens, L. crenulata and L. populicola) previously recorded for Argentina have not been confirmed as occurring in this country. Lecanora aff. fugiens is also treated and compared to the related species. The morphology, anatomy, secondary metabolites, distribution and ecology of the nine studied taxa are described and discussed, and a key to the taxa is included.

A New Species

The spider genus Oxyopes Latreille occurs throughout the world, but is insufficiently known in South America and the Caribbean. In this study, three apparently related species of this genus are reported from the region. Oxyopes salticus Hentz, 1845 is redescribed and illustrated, and extreme variation in colour pattern and in female genitalia is reported within this species. Oxyopes m-fasciatus Piza, 1938 and Oxyopes nigrolineatus Mello-Leitão, 1941 are both considered junior synonyms of O. salticus. The material examined in this study, together with information from the literature, show this species is widely distributed throughout the continental Americas and the Caribbean. Oxyopes crewi Bryant, 1948 is redescribed and illustrated, and its geographic distribution is extended to Bahamas, Cuba, Dominican Republic, Jamaica, and Saint Kitts. A new species, Oxyopes incantatus sp. nov., is described and illustrated for the first time based on specimens from the Galápagos Islands.

A new species of rust fungus, Puccinia marrubii sp. nov. is described from Turkey. The new species is the first Puccinia species to be identified on genus Marrubium (Lamiaceae). In order to determine the phylogenetic relationships of the new species, ITS region was amplified by PCR, sequenced, and analyzed. In addition to the ITS region of seven Puccinia species, P. annularis, P. jasmini, P. malvacearum, P. nigrescens, P. phlomidis, P. salviae, and P. serpylli were sequenced for the first time. Phylogenetic analyses performed by using distance, Bayesian methods confirmed that the new rust was closely related to P. serpylli, P. malvacearum, P. salviae, and P. annularis. The diagnostic morphological characteristics of the new species were discussed with the phylogenetically related species.

Nine new species of the collembolan genus Salina MacGillivray from South America are described and illustrated. Two Neotropical species were recorded for the first time from Brazil: S. dedoris Mari-Mutt and S. tristani Denis. Salina was previously known to occur in three Brazilian states, and this is now updated to include 19 states with 12 recorded species. A new proposal of morphological character description and illustration, and an identification key for the celebensis group are provided. A hypothesis for the phylogenetic relationships among 34 species of Salina (about 50% of the 72 described species) allowed three main pursuits: (a) a reevaluation of Salina species groups; (b) the first explicit interpretation of how morphological characters of these springtails may have changed during the course of the diversification of the taxon; and (c) an evaluation of the historical biogeographic connections of Salina, with an emphasis on the celebensis group distribution to the New World.

The fish family Characidae is one of the most diverse in number of species and poorly described from a phylogenetic standpoint. By analyzing RAG2 gene sequences of all representatives genera occurring in South America and query the databases of brazilian ichthyological collections, it was obtained a phylogeny of the genus and the patterns analysis of the geogrphical distribution of species in the major South America basins. The new phylogeny resolves groups which showed some uncertain phylogenetic relationships and, additionally, for the first time an analysis of geographical distribution of South American genera of Characidae is illustrated.

Drosophila suzukii (Diptera, Drosophilidae) is an exotic species, endemic to Asia and currently a pest to small and stone fruits in several countries of North America and Europe. It was detected in 2013 for the first time in South America, in the south of Brazil. Unlike most drosophilids, this species deserves special attention, because the females are capable of oviposit inside healthy fruits, rendering their sale and export prohibited. Despite the confirmed existence of this species in different states of Brazil, this insect is yet been to be given the pest status. Nevertheless, the mere presence of this species is enough to cause concern to producers of small fruits and to justify further investigation for it’s control, especially chemical control for a possible change in status. Therefore, the goal of this work was to evaluate, in laboratory, mortality of D. suzukii adults and ovicidal effect when exposed to different insecticides registered for species of the Tephritidae and Agromyzidae families in different cultures. The insecticides deltamethrin, dimethoate, spinosad, fenitrothion, phosmet, malathion, methidathion, and zeta-cypermethrin resulted in mortality to 100 % of the subjects three days after the treatment (DAT). Regarding the effects over eggs, it was  established that the insecticides fenitrothion, malathion, and methidathion deemed 100 % of the eggs not viable, followed by phosmet and diflubenzuron, which also caused elevated reduction in the eclosion of larvae two DAT.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.

AbstractRecent phylogenomic analyses based on the maternally inherited plastid organelle have enlightened evolutionary relationships between the subfamilies of Orchidaceae and most of the tribes. However, uncertainty remains within several subtribes and genera for which phylogenetic relationships have not ever been tested in a phylogenomic context. To address these knowledge-gaps, we here provide the most extensively sampled analysis of the orchid family to date, based on 78 plastid coding genes representing 264 species, 117 genera, 18 tribes and 28 subtribes. Divergence times are also provided as inferred from strict and relaxed molecular clocks and birth–death tree models. Our taxon sampling includes 51 newly sequenced plastid genomes produced by a genome skimming approach. We focus our sampling efforts on previously unplaced clades within tribes Cymbidieae and Epidendreae. Our results confirmed phylogenetic relationships in Orchidaceae as recovered in previous studies, most of which were recovered with maximum support (209 of the 262 tree branches). We provide for the first time a clear phylogenetic placement for Codonorchideae within subfamily Orchidoideae, and Podochilieae and Collabieae within subfamily Epidendroideae. We also identify relationships that have been persistently problematic across multiple studies, regardless of the different details of sampling and genomic datasets used for phylogenetic reconstructions. Our study provides an expanded, robust temporal phylogenomic framework of the Orchidaceae that paves the way for biogeographical and macroevolutionary studies.
