Larval endoparasitoids (Hymenoptera) of frugivorous flies (Diptera, Tephritoidea) reared from fruits of the cerrado of the State of Mato Grosso do Sul , Brazil

This paper presents a five years survey of endoparasitoids obtained from the larvae of frugivorous Tephritidae and Lonchaeidae flies. The insects were reared from cultivated and wild fruits collected in areas of the cerrado in the State of Mato Grosso do Sul, Brazil. The flies obtained from 14 host fruit species were eight Anastrepha species, Ceratitis capitata (Wiedemann, 1824) (Tephritidae); Dasiops sp. and Neosilba spp. (Lonchaeidae). Eleven parasitoid species were collected: Braconidae - Asobara anastrephae (Muesebek, 1958), Doryctobracon areolatus (Szepligeti, 1911), D. fluminensis (Costa Lima, 1938), Opius bellus Gahan, 1930 and Utetes anastrephae (Viereck, 1913); Figitidae - Aganaspis nordlanderi Wharton, 1998, Lopheucoila anastrephae (Rhower, 1919), Odontosema anastrephae (Borgmeier, 1935) and Trybliographa infuscata Gallardo, Diaz & Uchoa-Fernandes, 2000 and, Pteromalidae - Spalangia gemina Boucek, 1963 and S. endius Walker, 1839. In all cases only one parasitoid emerged per puparium. D. areolatus was the most abundant and frequent parasitoid of fruit fly species, as was L. anastrephae in Neosilba spp. larvae. This is the first record of A. nordlanderi in the midwestern Brazilian region.

Species of Eucoilinae (Hymenoptera: Cynipoidea: Figitidae) parasitoids of frugivorous larvae (Diptera: Tephritidae and Lonchaeidae) in Brazil

Os Eucoilinae, juntamente com os Opiinae (Braconidae), sao os mais importantes parasitoides de larvas frugivoras (Tephritoidea). No sentido de se conhecerem as especies de eucoilineos no Brasil, sua distribuicao geografica, hospedeiros associados e percentagem de parasitismo, 170 amostras de parasitoides de 51 municipios das cinco regioes do Brasil foram examinadas. Obtiveram-se 2025 eucoilineos, dos quais seis especies (42,82%) estao associadas as larvas frugivoras. Foi possivel associar os parasitoides a sete especies de moscas e a 33 especies de fruteiras de 15 familias. Os eucoilineos sao generalistas, parasitando tanto as especies do genero Anastrepha (Tephritidae) quanto especies da familia Lonchaeidae. Aganaspis pelleranoi (Brethes) e a especie mais abundante (29,93%) e com a mais ampla distribuicao no Brasil. Dicerataspis flavipes (Kieffer) foi obtida no Estado de Sao Paulo, associada somente as especies do genero Anastrepha; e mais atraida por carambola, pois 96,34% dos especimes foram obtidos de larvas nesse fruto. Lopheucoila anastrephae (Rhower) e Odontosema anastrephae Borgmeier estao associadas a Anastrepha pseudoparallela (Loew) e as especies de Neosilba em Passifloraceae (primeiros registros). Aganaspis nordlanderi Wharton foi encontrada associada a Anastrepha bahiensis Lima no Estado do Amazonas (primeiros registros da localidade e da mosca hospedeira). Aganaspis pelleranoi, D. flavipes e L. anastrephae foram associadas a Anastrepha amita Zucchi em pombeiro (Citharexylum myrianthum Cham.) no Estado de Sao Paulo (primeiros registros de localidade e da mosca hospedeira). Trybliographa sp., que parasita principalmente lonqueideos, e registrada pela primeira vez no Brasil, no Estado de Sao Paulo. A percentagem de parasitismo variou de 0,07 a 42,86%, em razao do local da coleta, especies de frutos e moscas hospedeiras.

Cynipoidea parasitoids of dung-flies in Brazil. II (Insecta: Hymenoptera)

This paper deals with 11 species of Cynipoidea parasitoids of dung-flies in Brazil: Neralsia splendens (Borgmeier 1935), Triplasta (Triplasta) atrocoxalis (Ashmead 1895), Triplasta (Pentaplasta) coxalis (Ashmead 1895), Acantheucoela armata (Cresson 1865), Acantheucoila brevispina Dettmer 1930, Acantheucoila coprophila Borgmeier 1935, Acantheucoila fumipennis Borgmeier 1935, Coneucoela brasiliensis Kieffer 1909, Ganaspis fulvocincta Kieffer 1909, Kleidotoma nigra (Hartig 1840), and Paraganaspis egeria Diaz & Gallardo 1996. An illustrated key for their identification, the hosts and the geographic distribution for each species are also given.

South American Charipinae: Review and Description of Two New Species (Hymenoptera: Cynipoidea: Figitidae)

Abstract The Charipinae have been little studied in the Neotropical region. There are only three species in South America and some identifications are erroneous. In this work, all the species of Charipinae from South America were studied and two new species are described: Apocharips angelicae Pujade-Villar and Evenhuis sp. n. and Alloxysta desantisi Pujade-Villar and Díaz sp. n. New synonyms also are given. Several unusual morphological features of Apocharips angelicae are discussed and illustrated. Finally, we argue that the genera Bothriocynips and Emargo are synonymous.

Descripción de nueve especies sudamericanas del género Neralsia Cameron, con carena escutelar baja (Hymenoptera: Cynipoidea: Figitidae)

In this study a total of nine new species of the genus Neralsia are described for South America: N. desantisi Jimenez & Pujade-Villar n. sp., N. equilatera Jimenez & Pujade-Villar n. sp., N. hermafrodita Jimenez & Pujade-Villar n. sp., N. marioi Jimenez & Pujade-Villar n. sp., N. moisesi Jimenez & Pujade-Villar n. sp., N. obelix Jimenez & Pujade-Villar n. sp., N. parafossulata Jimenez & Pujade-Villar n. sp., N. pseudoneralsia Jimenez & Pujade-Villar n. sp. and N. rauli Jimenez & Pujade-Villar n. sp., all of them have in common the low carina separating the scutellar foveae. Other six known Neralsia species, N. albipennis (Kieffer), N. bogotensis (Kieffer), N. flavidipennis (Kieffer), N. fossulata (Kieffer), N. pilosa (Borgmeier) and N. striaticeps (Kieffer) have the same scutellar character. The morphological characters to differentiate all mentioned species are presented.

Systematic Review of Species of the genus Aganaspis Lin (Hymenoptera: Figitidae: Eucoilinae)

Abstract The type material of Aganaspis species is studied. Two species groups are described: the A. contracta species group (including A. contracta Lin) and the A. daci apecies group (including A. daci Weld, A. ocellata Lin and A. major Lin); A. pelleranoi (Brèthes) and A. nordlanderi Wharton are transfered to another genus. The name Ganaspis pelleranoi is re-established and the new combination Trybliographa nordlanderi is formed.

Contribution to the systematics of Dicerataspis Ashmead, 1896 (Hymenoptera: Cynipoidea: Figitidae).

ABSTRACT: This paper deals with the identity, geographical distribution and host associations of Dicerataspis species. The authors propose the new synonymy Dicerataspis grenadensis Ashmead, 1896 (= D. flavipes Kieffer, 1909) and redescribe and illustrate D. grenadensis.

A new species of Zamischus (Hymenoptera, Cynipoidea, Figitidae) from Brazil

A new species of Zamischus (Hymenoptera, Cynipoidea, Figitidae) from Brazil. A new species of Zamischus from Brazil is described and diagnosed. The species is closely related to Z. brasiliensis but differs in the morphology of antennae and scutellum. Z. aquilesi sp. nov. was collected via Malaise trapping in a tobacco field in Santa Cruz do Sul, Rio Grande do Sul.
