Two new species of Drosophila (Diptera, Drosophilidae) associated with inflorescences of Goeppertia monophylla (Marantaceae) in the city of São Paulo, state of São Paulo, Brazil

Abstract Two new Brazilian species of Drosophila (subgenus Drosophila) are described and illustrated: Drosophila asymmetrica sp. nov. and Drosophila peixotoi sp. nov. Both species were collected, and emerged, from inflorescences of Goeppertia monophylla (Marantaceae) in the urban Forest Reserve of the Instituto de Biociências da Universidade de São Paulo and their types will be deposited in the Museu de Zoologia da USP. The former species, which could not be assigned to any known group, has a conspicuously asymmetric aedeagus and a narrow oviscapt valve. The latter species belongs to the guarani group and is closely related to D. guaru, D. ornatifrons and D. subbadia, from which it can be distinguished by the presence of just one conspicuous large black spine at inner lower tip of cercus instead of two spines.

The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil)

The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil). Drosophila suzukii (Matsumura, 1931), the cherry fly or spotted-wing Drosophila, a pest species from the Oriental and southeastern Palaearctic regions belonging to the melanogaster group, invaded the Nearctic and western countries of the Palaearctic regions late last decade (2008) and, more recently (2013), the southern Brazilian states of Rio Grande do Sul and Santa Catarina. Early in 2014 it was reared from blueberries produced in São Joaquim, state of Santa Catarina, that were bought at a São Paulo city grocery store. Despite being a cold-adapted species, after having arrived to the southeastern state of São Paulo, this invasive fly will probably expand its territory to other Brazilian states and South American countries through trade of cultivated soft skin small fruits, such as blueberries and strawberries, as well as naturally through the use of small wild fruits as breeding sites.

On Marta Breuer and some of her unpublished drawings of Drosophila spp. male terminalia (Diptera, Drosophilidae)

A short illustrated biography of Marta Erps Breuer (1902-1977), designer and lab technician at the University of São Paulo (Universidade de São Paulo), and a former Bauhaus student, is presented. Additionally, twenty fine China ink drawings of the male terminalia of twenty species of Neotropical Drosophila, made by her between October 4th, 1951, and March 24th, 1959, and currently deposited in the archives of the Department of Genetics and Evolutionary Biology of the Institute of Biosciences of the University of São Paulo (Departamento de Genética e Biologia Evolutiva, Instituto de Biociências, Universidade de São Paulo), São Paulo, State of São Paulo, Brazil, are included. All illustrated species but one are members of one of the following seven groups of the subgenus Drosophila: annulimana, canalinea, cardini, coffeata, dreyfusi, repleta, and tripunctata. Besides being depicted in the same position, the illustrations are so precise that we believe they will be extremely useful for those interested in Drosophila spp. identification. A comprehensive list of her scientific papers is included among the references.

Breeding sites of Neotropical Drosophilidae ( Diptera ): IV. living and fallen flowers of Sessea brasiliensis and Cestrum spp. ( Solanaceae )

As fenologias de floração de quatro espécies de Solanaceae (Sessea brasiliensis, Cestrum amictum, C. schlechtendalii e C. sendtnerianum) presentes em um fragmento de Floresta Atlântica de planalto, encravado na cidade de São Paulo, foram determinadas por observações realizadas entre julho de 1993 e junho de 1995. Durante esses dois anos foram coletadas 33.955 flores das quais emergiram 11.021 moscas pertencentes a cinco espécies de Drosophila do grupo flavopilosa (D. cestri, D. cordeiroi, D. hollisae, D. incompta e D. mariaehelenae) e 1.244 moscas pertencentes a quatro espécies Zygothrica (Z. dispar, Z. vittimaculosa, Z. vittinubila e Z. aff. vittipunctata). Adicionalmente, das flores de S. brasiliensis e Cestrum spp. amostradas emergiram pelo menos outros dez táxons menos abundantes de Drosofilídeos e 1.073 microimenópteros parasitóides (Braconidae, Eucoilidae e Pteromalidae). Flores de Cestrum amictum, C. sendtnerianum e Sessea brasiliensis são registradas pela primeira vez como plantas hospedeiras para as espécies neotropicais de Drosophila pertencentes ao grupo flavopilosa. Os resultados aqui apresentados elevam de nove para onze o número de espécies de Cestrum previamente conhecidas como sítios de desenvolvimento larval dessas moscas. Inclui-se ainda uma lista completa das espécies de Solanaceae que já foram registradas nas regiões sudeste e sul do Brasil como plantas hospedeiras de seis espécies de Drosophila do grupo flavopilosa e de quatro espécies de Zygothrica.
