A new species of Buenoa Kirkaldy (Hemiptera, Heteroptera, Notonectidae) from Rio de Janeiro, Brazil

Members of Buenoa are restricted to the Western Hemisphere, with the greatest diversity of species in South America. There are about 50 described species and approximately 20 of them have been reported from Brazil. Buenoa pseudomutabilis Barbosa, Ribeiro and Nessimian, sp. nov. is described here from Maricá, Rio de Janeiro State. This species resembles B. mutabilis Truxal, 1953 because males have a stridulatory area on inner surface of forefemur, forefemur narrowed at apex, with length more than three times its width at apex, and rostral prong longer than third rostral segment. Males of B. pseudomutabilis sp. nov. can be readily recognized by the presence of 21 to 25 teeth in the stridulatory comb of foretibia, whereas in B. mutabilis the stridulatory comb of foretibia consists of approximately 33 to 38 teeth. Males of B. pseudomutabilis sp. nov. bear one nodule on each ventral laterotergite 1 of abdomen. A key to male species of Buenoa occurring in Rio de Janeiro State, including the new species, is provided.

Aurigoniella meridionalis, sp. nov. is described and illustrated from Morretes and São José dos Pinhais, Paraná State, southern Brazil. It can be easily distinguished from the Aurigoniella type-species, A. dutrai, by its distinct color pattern, smaller size, shorter crown, hindleg knees attaining lateral lobe of pronotum, aedeagus broadest height around mid-length, and paraphyses ramus biramous.

A new species of Eufriesea Cockerell (Hymenoptera, Apidae, Euglossina) from northeastern Brazil

A new species of Eufriesea Cockerell (Hymenoptera, Apidae) from northeastern Brazil. Eufriesea pyrrhopyga sp. nov. a short-tongued Eufriesea is described as a new species. It can be easily recognized for its predominantly violet lower frons and thorax, violet tergum 1 contrasting with the strong reddish coloration on the lateral portions of terga 2 to 4 and on entire terga 5 and 6, and head pubescence with contrasting colors, white on the lower two-thirds of the face and black on upper frons and vertex. This new species, collected in Recife (Pernambuco, Brazil), apparently is restricted to the Pernambuco endemic center, and seems to be highly endangered.

Neodexiopsis Malloch from Bolivia with the description of one new species (Diptera, Muscidae)

Neodexiopsis Malloch from Bolivia with the description of one new species (Diptera, Muscidae). Neodexiopsis Malloch (Diptera, Muscidae, Coenosiinae) is a very well represented genus in the Neotropical Region, known from almost 100 species. In Bolivia, it is known only from four species: N. declivis, N. incurva, N. oculata and N. recedens, all described by Stein. The study of material from South America deposited at Muséum national d'Histoire naturelle (Paris, France), enabled the description of one new species to science. A key for the recognition of the five species known to Bolivia is given.

A new species of Eccopsis Zeller (Lepidoptera, Tortricidae) from the coastal valleys of northern Chile, with the first continental record of E. galapagana Razowski & Landry

A new species of Eccopsis Zeller (Lepidoptera, Tortricidae) from the coastal valleys of northern Chile, with the first continental record of E. galapagana Razowski & Landry. Eccopsis Zeller, 1852 is reported for the first time from Chile. Eccopsis razowskii Vargas, n. sp. is described and illustrated based on specimens reared from larvae collected on native Acacia macracantha Willd. (Fabaceae) in the coastal valleys of the northern Chilean desert. Eccopsis galapagana Razowski & Landry, 2008, previously known only from the Galapagos Islands, Ecuador, is recorded for the first time from continental South America. Larvae of the latter were collected in northern Chile feeding on Prosopis alba Griseb (Fabaceae).
