The Ephemeroptera fauna in Venezuela is poorly known, as is also the case in others areas in South America. Recently, two studies increased from 33 to 50 the number of species recorded in Venezuela. The objective of the present study is to report for the first time in Venezuela the following species:Baetodes levis;Camelobaetidius edmundsi;Fallceonsp.;Mayobaetis ellenae.The nymph ofFallceonsp. is described, but is not named because adults were not reared to allow species identification; however, description of this nymph indicates the presence of this genus in South America.

Abstract ITS2 (Internal transcribed spacer 2) sequences have been used in systematic studies and proved to be useful in providing a reliable identification of Trichogramma species. DNAr sequences ranged in size from 379 to 632 bp. In eleven T. pretiosum lines Wolbachia-induced parthenogenesis was found for the first time. These thelytokous lines were collected in Peru (9), Colombia (1) and USA (1). A dichotomous key for species identification was built based on the size of the ITS2 PCR product and restriction analysis using three endonucleases (EcoRI, MseI and MaeI). This molecular technique was successfully used to distinguish among seventeen native/introduced Trichogramma species collected in South America.

Marine isopods, despite being a very diverse group, have been little studied in the Mexican South Pacific. After a revision of 171 specimens collected from Guerrero and Oaxaca, six new species, belonging to five genera, were discovered: Amakusanthura guerrerensis sp. nov., Cortezura caeca sp. nov., Mesanthura antenniformis sp. nov., M. estacahuitensis sp. nov., Skuphonura oaxaquensis sp. nov., and Tinggianthura mexicana sp. nov. In this work, the genera Amakusanthura Nunomura, 1977 and Tinggianthura Chew, Abdul-Rahim & Haji Ross, 2014, are recorded for the first time in the Tropical Eastern Pacific. Also, the distribution range of the genus Skuphonura Barnard, 1925 is increased from the west coast of South America to the southern Mexican Pacific, this being the first record of this genus in the Mexican Pacific. This study doubles the number of species recorded of Anthuridae from the Mexican Pacific, of six to 12 species.

Abstract Unionida is the most diverse clade of freshwater bivalves. Among the groups occurring in South America, one with the highest number of species is Rhipidodontini (Hyriidae, Unionida, Paleoheterodonta, Bivalvia). However several issues remains on taxonomy and systematic of this group, leading to problems on species identification, description, as also as a limiting factor to other type of studies (e.g., ecology, conservation,…). In this paper is presented a synthesis of available knowledge about Diplodon Spix in Wagner, 1827 and Rhipidodonta Mörch, 1853 in South America, as a first step in order to a better understating of Rhipidodontini. The evaluation of different authors exposes the little agreement between them that resulted in a sort of divergent taxonomical opinions. Some comments on ecology, conservation and habitat preferences were made. This work can also encourage future research on taxonomy, systematic, ecology and conservation of freshwater mussels in South America.

A list of the stink bugs (Pentatomidae) species of the Brazilian Amazon is provided for the first time, based on literature review and identification of the specimens of Pentatomidae deposited in the entomological collection of the Museu Paraense Emílio Goeldi (MPEG). Amazonian data base presented here has 324 species of Pentatomidae belonging to 102 genera, ten tribes and five subfamilies: Asopinae, Cyrtocorinae, Discocephalinae, Edessinae and Pentatominae. The Pentatominae has the largest number of species registered to Brazilian Amazon (144 species). The MPEG entomological collection has 122 species distributed in 53 genera, nine tribes and five subfamilies. Forty species from eight tribes and four subfamilies are recorded for the first time to Brazilian Amazon, including species from Podisus Herrich-Schäffer (Asopinae); Adoxoplatys Breddin, Macropygium Spinola, Neoadoxoplatys Kormilev, Ochlerus Spinola and Platycarenus Fieber (Discocephalinae); Edessa Fabricius (Edessinae); Arocera Spinola, Arvelius Spinola, Banasa Stål, Dichelops Spinola, Euschistus Dallas, Mormidea Amyot & Serville, Oebalus Stål, Pellaea Stål, Piezodorus Fieber, Proxys Spinola and Thyanta Stål (Pentatominae). Three of these species–Podisus maculiventris (Say, 1831) Neoadoxoplatys saileri Kormilev, 1956 and Edessa laticornis Stål, 1872—are new records to South America. The number of species of Pentatomidae to Brazilian Amazon represents approximately 50% of the species registered to Brazil. Such list of species is important to better understand the distributional range and diversity of the species of Pentatomidae in the Amazon region.

We captured mormoopids, phyllostomids, and vespertilionids in Honduras to collect bat ectoparasites. Two species of Spinturnicidae (Acari) are the first reports of this family in Honduras. One species of Basilia Miranda Ribeiro, 1903, and four of Streblidae are recorded for the first time in Honduras. With these results, the current species number of each family for Honduras are two species of Spinturnicidae, three of Nycteribiidae, and 48 of Streblidae. We compared the number of species of Streblidae and bats in Honduras to highly sampled countries in Central and South America. Clearly, more effort is still needed in Honduras, although this is the third attempt to study the bat ectoparasites in Honduras.

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.

Abstract Bovine coccidiosis is a disease of major importance in cattle herds across the world. The disorder mainly affects young calves, and E. bovis and E. zuernii are considered the most pathogenic species of the genus, however, E. alabamensis have been described in grazing calves. In this study, the prevalence of Eimeria spp. was evaluated in calves on dairy farms in the northern region of the state of Paraná, Brazil. Four hundred calves on 44 dairy farms were tested for the presence of coccidian oocysts. The positives were re-examined and the oocysts were morphometrically analyzed for species identification. All the farms were contaminated and 205 animals (51.25%) presented Eimeria spp. oocysts. Among these, 146 animals (71.22%) were co-infected by two or more species of coccidia. Ten species of Eimeria were identified: E. bovis (in 30.25% of the positive samples), E. alabamensis (26.75%), E. zuernii (22.00%), E. ellipsoidalis (18.50%), E. auburnensis (13.75%), E. canadensis (8.00%), E. cylindrica (7.25%), E. subspherica (5.00%), E. bukidnonensis (3.00%) and E. brasiliensis (0.75%). This study demonstrates the high prevalence of Eimeria spp. in the northern region of Paraná, Brazil, and detection for the first time in our region the pathogenic species E. alabamensis.
