The orchid-bee fauna of the region of Tarapoto, northeastern Peru, was surveyed using seventeen different scents as baits to attract orchid-bee males. Six hundred and fifty-nine males belonging to 41 species were actively collected with insect nets during 120 hours in late July and early August, 2012. Euglossa dressleriMoure, 1968, Euglossa laurensiBembé, 2008, and Euglossa maculilabrisMoure, 1968, three species belonging to the Euglossa cybelia species-group, are here reported for Peru for the first time. Previous sporadic and unpublished samplings in the area recorded eleven additional species. With 53 species, the region of Tarapoto can be considered the richest single site in the Neotropics for orchid bees. Diversity, estimated with the Shannon-Wiener diversity index (H′ = 3.02), was also the highest ever recorded for orchid bees.

The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging to Usina Serra Grande, in the states of Alagoas and Pernambuco, were surveyed using seventeen different scents as baits to attract orchid-bee males. Eight sites were established in the three preserves, where samplings were carried out using two protocols: insect netting and bait trapping. We collected 3,479 orchid-bee males belonging to 29 species during 160 hours in early October, 2012. Seven species were collected in the “Centro de Endemismo Pernambuco” for the first time. Richness proved to be one of the highest of the entire Atlantic Forest domain, and diversity in some sites, especially at ESEC Murici, revealed to be one of the highest in the Neotropics. Eulaema felipei Nemésio, 2010, a species previously recorded only at ESEC Murici, was found in no other preserve in the region and its conservation status is discussed.

The taxonomic status (or the taxonomic status of the onomatophores) of seven nomina are revised: Eulaema meriana (Olivier, 1789), Euglossa piliventris Guérin-Méneville, 1844, Exaerete appendiculata (Romand, 1849), Exaerete subcornuta (Romand, 1849), Eufriesea danielis (Schrottky, 1907), Euglossa fimbriata Moure, 1968, and Eufriesea yepezi (Moure, 2000). Lectotype is designated for Euglossa piliventris Guérin-Méneville, 1844. Neotypes are designated for Apis meriana Olivier, 1789 and Apis dimidiata Fabricius, 1793 based on the same specimen and A. dimidiata Fabricius, 1793 became an objective synonym of A. meriana Olivier, 1789. Chrysantheda subcornuta Romand, 1849 is shown to be a senior objective synonym of Chrysantheda appendiculata Romand, 1849 and their synonymy under Exaerete dentata (Linnaeus, 1758) is questioned and discussed. Eumorpha combinata danielis Schrottky, 1907 is confirmed as a junior subjective synonym of Eufriesea auriceps (Friese, 1899), but the status of its onomatophore is reconsidered. Moreover, a long overlooked Euglossa dentata var. maxima Romand, 1849, nom. nud. and Euplusia yepezi Moure, 2000, nom. nud. are discussed for the first time. Both nomina Euglossa fimbriata Moure, 1968 and Euglossa fimbriata Rebêlo & Moure, 1996are available, but the latter is permamently invalid as a junior primary homonym of the former. An updated catalogue of all orchid bee nomina is also provided.

The orchid-bee fauna of ‘Reserva Biológica de Una’ (REBIO Una), one of the largest Atlantic Forest remnants in southern Bahia, eastern Brazil, was surveyed for the first time. Baits with sixteen different scents were used to attract males of orchid bees. Eight hundred and fifty-nine males belonging to 26 species were actively collected with insect nets during 60 hours in January and February, 2009, and January, 2010. Euglossa avicula Dressler, 1982 and Euglossa milenae Bembé, 2007 have been recorded for the first time in the state of Bahia. It was found that REBIO Una has one of the most diverse and rich orchid-bee faunas of the entire Atlantic Forest domain and holds some rare species, such as Euglossa cyanochloraMoure, 1996.

Abstract This study focuses on the taxonomy of epiphytic diatoms in the area of invasive macroalgae from the genus Caulerpa. Caulerpa species are characterized by the presence of secondary metabolites, such as caulerpenyne (CYN), the main function of which is a chemical defense mechanism against herbivores and epiphytes. Epiphytic diatoms were studied on fronds of Caulerpa taxifolia (“killer seaweed”) and, for comparison, on autochthonous macroalgae Padina sp. and Halimeda tuna at the eastern Adriatic Sea coast (Island of Hvar) in the summer and autumn of 2010. The qualitative analysis was performed with the use of light and scanning electron microscopy. The Shannon–Wiener Diversity Index determined for Caulerpa taxifolia showed a wide range of values (3.11–4.88), with a maximum in August and a minimum in October. While the number of taxa on Caulerpa taxifolia fronds increased from June (41) to August (88), it declined in autumn due to the high relative abundance of Cocconeis caulerpacola, which is a diatom typical for Caulerpa. On the other hand, the largest number of taxa on Padina sp. was observed in September (82). The detailed composition of epiphytic diatoms and seasonal dynamics in the area affected by the invasive macroalga Caulerpa taxifolia have been determined for the first time.

The purpose of this work was to describe the population patterns of Anastrepha in three municipalities of the state of Roraima, Brazil, via faunistic analysis. Weekly collections were performed from January through December 2008, using McPhail traps containing 5% hydrolysed protein, in domestic orchards in the municipalities of Boa Vista, Bonfim and Pacaraima. We captured 301 females of Anastrepha in Boa Vista, 212 in Bonfim, and 167 in Pacaraima. Boa Vista presented the highest species richness (S = 10) and Pacaraima the lowest (S = 4). Anastrepha striata was the predominant species in Boa Vista (47.18%) and Pacaraima (65.87%), whereas A. obliqua predominated in Bonfim (46.23%). Boa Vista presented the highest Shannon-Wiener diversity index (H' = 1.19) and Margalef index (α = 1.58), and Bonfim presented the highest Pielou's evenness index (J' = 0.69). In Pacaraima the cumulative curves reached stability, confirming that the observed and expected species richness were the same. In the other two municipalities, the curves showed a moderate growth, suggesting that the sampling effort was not sufficient to produce an accurate depiction of species richness. In this study, Anastrepha zernyi is reported for the first time in Roraima.

The members of the genus Pelthydrus are small-sized aquatic beetles which belong to the water scavenger beetle family Hydrophilidae. At present the lineage includes 63 valid species mainly occurring in Asia, with 21 known from China (Bian et al. 2008, 2009; Hansen 1999; Schönmann 1995). One new species is described here, which belongs to the Pelthydrus sculpturatus species group, bringing the total number of species within the group to seven (Schönmann 1995). One additional species is reported from China for the first time. Specimens were collected from Yunnan Province and are deposited in IAECAS (Institute of Applied Ecology, Shenyang, Chinese Academy of Sciences).

The orchid bee faunas of Floresta Nacional do Rio Preto, Reserva Biológica Córrego Grande, and Reserva Biológica Córrego do Veado, in the northernmost portion of the state of Espírito Santo, southeastern Brazil, were surveyed for orchid bees for the first time. A total of 1,603 males belonging to 24 species were attracted to 16 different scent baits and actively collected with insect nets during 100 hours from December, 2009, to February, 2010. One species of Euglossa, known as strongly dependent on well preserved mature forests, once recorded at the region, was not found in this survey and may indicate the first documented local extinction of an orchid bee species. This species, which Atlantic Forest population has been treated as Euglossa analis Westwood, 1840, is here considered a new species, Euglossa marianae sp. n.

Ant diversity was studied in Muhan Pokhari area of Shivapuri-Nagarjun National Park (SNNP)at 1,700 m to 1,900 m asl during winter and summer seasons of 2017. Ants were collected using pitfall traps, leaf litter sampling, bait and hand collection methods along a transect of50 m in each of all 5 sites (1,700 m, 1,750 m, 1,800 m, 1,850 m and 1,900 m). Altogether 817individual ants were collected representing 5 sub-families, 16 genera and 23 morpho species. Formicinae (57.67%) was the most abundant sub-family, followed by Myrmicinae (40.39%), Pseudomyrmicinae (0.8%), Ponerinae (0.73%) and Dolichoderinae (0.37%). Camponotus (437individuals) was the most abundant genus followed by Aphaenogaster (287). Species richness was higher in winter (17 morph species) than in spring (14 morph species). Shannon-Wiener diversity index (1.4618) and Evenness index (0.5539) were higher in spring season. Pitfall trap method was found most effective with highest number of individual ants (567) and of 21 species. The Shannon-Weiner diversity index was highest for pitfall method (1.3039) whereas evenness index was highest for the bait method (0.62615). Two genera Pachycondylaand Echinopla were recorded for the first time in Nepal.

The orchid-bee fauna of the region of Porto Velho, in the state of Rondônia, Brazil, close to the southernmost limits of the Amazon Basin, was surveyed for the first time using five different scents as baits to attract orchid-bee males. Five hundred and twenty-one males belonging to five genera and 29 species were collected with bait traps during 26 non-consecutive days from November, 2011 to January, 2012. Eulaema nigrita Lepeletier, 1841 and Eulaema meriana (Olivier, 1789) were the most common species in the region and, together, represented almost 50% of all collected bees. Although the observed richness conforms to similar inventories in the region, the diversity (H′= 2.43) found in the present study is one of the highest ever recorded for orchid bees in the Amazon Basin.
