NEW Stylogaster AND RANGES OF CONOPIDAE (DIPTERA) FROM THE BRAZILIAN AND BOLIVIAN AMAZONIA

Conopid flies from the collection of the Instituto Nacional de Pesquisas da Amazonia, Manaus, Brazil, are examinied, of which two from Brazil are new, Stylogaster rafaelifrom Rondônia and S. ctenitarsafrom Roraima. This data, along with new material from Bolivia, expands the distributions of thirteen species of Conopidae. Figures for S. rafaelisp.n. and S. ctenitarsasp.n. are included.

Insecta Amapaensia: Diptera conopidae: espécies do gênero Stylogaster macquart, 1835

Dans le présent travail quatre espèces nouvelles de Stylogaster Macq. ont été décrites avec le dessin des respectives "genitalia" pour mieux déterminer les espéces. Ils ont été faits aussi dessins du mâle de Stylogaster stylata Fabricius pour la comparaison avec S. souzai sp. n. Nous avons utilisé, pour cette étude, le matériel collecté par John Lane au Território do Amapá, Brasil en 1957, 1958 et 1959.

Revisão das espécies de Stylogaster Macquart do grupo stylata com descrição de uma espécie nova do Brasil (Diptera, Conopidae, Stylogasterinae)

As espécies brasileiras de Stylogaster Macquart, 1835 do grupo stylata são detalhadamente estudadas e redescritas: Stylogaster brasilia Camras & Parrillo, 1985, S. dispar Camras & Parrillo, 1985, S. longispina Camras & Parrillo, 1985, S. rafaeli Camras & Parrillo, 1996, S. souzai Monteiro, 1960, and S. stylata (Fabricius, 1805). Uma nova espécie do Brasil, Rio de Janeiro - S. fluminensis sp. nov., é descrita e comparada com S. stylosa Townsend, 1897, redescrita com base no material-tipo. Diagnoses, chaves de identificação, distribuição geográfica e ilustrações são também fornecidas.

Diptera hosts of Stylogaster Macquart (Diptera, Conopidae) from Madagascar and South Africa

The genus Stylogaster Macquart (Diptera, Conopidae) is represented by 14 species in the Afrotropical region, five of them endemic to Madagascar and two recorded from South Africa, one of them endemic. Fifteen specimens of Muscidae, 14 from Madagascar and one from South Africa, belonging to 10 species, impaled with Stylogaster eggs were examined. Among them, three new muscid host species were found. The dissected eggs were all similar, suggesting the presence of the same species in both localities, what is not recorded until now. The available data on the dipteran Stylogaster eggs hosts in Africa is summarized. Color photos of the material examined are presented.

Larval development of Physocephala (Diptera, Conopidae) in the bumble bee Bombus morio (Hymenoptera, Apidae)

Larval development of Physocephala (Diptera, Conopidae) in the bumble bee Bombus morio (Hymenoptera, Apidae). In the summer of 2012, a high incidence of conopid larvae was observed in a sample of female B. morio collected in remaining fragments of semidecidual forest and Cerrado, in the municipality of Sorocaba, state of São Paulo, Brazil. The larval development of conopid flies was studied, beginning at the larval instars (LO to L3) and PUP, until the emergence of the imago under laboratory conditions and inside the host. At the first instar, or LO, the microtype larvae measured less than 1 mm in length. During the transition from L1 to L3, the larvae grew in length. At L3, the larvae doubled their length (4 mm) and then started to develop both in length and width, reaching the PUP stage with 10 mm in length and 7 mm in width. The main characteristic that differentiates L3 from the early instars is the larger body size and the beginning of posterior spiracle development. The development from PUP to puparium took less than 24h. The bees died ten days after the fly oviposition, or just before full PUP development. The early development stages (egg-LO to L1) were critical for larva survival. The pupa was visible between the intersegmental sternites and, 32 days after pupation, a female imago of Physocephala sp. emerged from one bee. The puparium and the fly measured approximately 10 mm in length. In a single day of collection, up to 45% of the bumble bees collected were parasitized by conopid flies.

A new species of Stylogaster from Brazil (Diptera: Conipidae)

A new species of Stylogaster is described from Roraima, Brazil. It belongs to the neglecta-group of species.

Myospila bekilyana (Séguy) (Diptera, Muscidae, Mydaeinae): redescription of male and female and description of terminalia

Myospila bekilyana Séguy (Diptera, Muscidae, Mydaeainae) is an endemic species from Madagascar. Since the original description, the species has been referred in literature only in catalogues. A material recently collected by the Madagascar Arthropod Biodiversity project, mostly deposited at the California Academy of Sciences collection enabled the exam of a large series of this species. Male and female are herein redescribed and the terminalia of both sexes are described and illustrated for the first time. The paper also records Myospila as a new host for Stylogaster Macquart (Diptera, Conopidae).
