ABSTRACT
Background: Alysiinae Leach is a species-rich subfamily in Braconidae, of which several species play an important role in biological control. The monotypic genus Eurymerostumespiraculum Bhat, 1980 was discovered in Tibet and Yunnan provinces for the first time, representing the first record of the genus Eurymeros Bhat, 1980 (Braconidae, Alysiinae) in China. New information: The rare genus Eurymeros Bhat, 1980 (Braconidae, Alysiinae) and its only known species, E.tumespiraculum Bhat, 1980, are newly recorded from China. The morphological variation of the Chinese specimens is described and illustrated.

The braconid parasitoids of fruit-infesting flies have been more intensively studied from the middle to late 1990s, when taxonomic research was restarted in Brazil. At the same time, efforts toward the biological control of fruit flies intensified, and an exotic species, Diachasmimorpha longicaudata, was introduced. In the decade 2010, another exotic species, Fopius arisanus, was introduced, and two new species of Doryctobracon were described. Currently, 12 species of braconids from the subfamilies Alysiinae (two species) and Opiinae (10 species) are associated with fruit flies of economic importance in Brazil, two of which are introduced species. More than half of the species belong to the genus Doryctobracon, with D. areolatus (Szépligeti) the most widely distributed species in Brazil.

An illustrated key to the genera and subgenera of the Alysiini (Hymenoptera, Braconidae, Alysiinae) from China is presented. Three genera new for China are reported: Adelurola Strand, 1924, Anisocyrta Foerster, 1863, and Pentapleura Foerster, 1863. The total for China is 26 genera of Alysiini and an additional seven subgenera (excluding the nominal subgenera, which are included in the total of genera). The known Chinese species are listed under each genus and the biology is summarised. Separatatus sinicus (Zheng, Chen & Yang, 2012) and Grammospila eurys (Chen & Wu, 1994) are new combinations. Regetus Papp, 1999, and Adelphenaldis Fischer, 2003, are new synonyms of Eusynaldis Zaykov & Fischer, 1982. In addition, Eusynaldis Zaykov & Fischer and Synaldis Foerster, 1863, are treated as subgenera of Aspilota Foerster, 1863, and Dinotrema Foerster, 1863, respectively. An aberrant species of Separatatus Chen & Wu, 1994, S. parallelussp. n., is described from Yunnan and Hainan.

A new species from Central Urals, Protochorebus pervushini sp. nov., is described and illustrated. The new material for Asyntactus rhogaleus Marshall, 1898 is studied. A key to Protochorebus species is provided. Description of puparium of Selachops flavocinctus and new data on its life history are published for the first time.

ABSTRACT
Foram coletados 3.008 braconídeos em larvas/pupas de moscas-das-frutas em 26 espécies de frutos, distribuídos em 33 municípios paulistas. A maioria dos braconídeos pertencia a Opiinae (96,2 por cento), representada por quatro espécies - Doryctobracon areolatus (Szépligeti), Doryctobracon brasiliensis (Szépligeti), Opius bellus (Gahan) e Utetes anastrephae (Viereck) - e os demais a Alysiinae (3,8 por cento), representada apenas por Asobara anastrephae (Muesebeck). Doryctobracon areolatus foi atraída por mais frutos hospedeiros de moscas-das-frutas (26) e ocorreu na maioria dos municípios amostrados, totalizando 77,5 por cento dos parasitóides coletados. Doryctobracon areolatus foi associada com Anastrepha fraterculus (Wied.), A. obliqua (Macquart), A. amita Zucchi e, pela primeira vez, em frutos de wampi (Clausena lansium) e em canela-batalha (Cryptocarya aschersoniana). Doryctobracon brasiliensis foi associada apenas com A. fraterculus e registrada, pela primeira vez, em larvas em ameixa-japonesa (Prunus salicina). Não foi possível associar as demais espécies de parasitóides às espécies de moscas-das-frutas. Opius bellus foi obtida de larvas em canela-batalha. A percentagem de parasitismo natural variou de <1 por cento a 40 por cento.
A total of 3,008 braconid parasitoids in 26 species of fruit fly host plants were collected in 33 localities of São Paulo State. The majority of the braconids (96.2 percent) belonged to four Opiinae species, Doryctobracon areolatus (Szépligeti), Doryctobracon brasiliensis (Szépligeti), Opius bellus (Gahan) and Utetes anastrephae (Viereck), and the remaining 3.8 percent, a single species of Alysiinae, Asobara anastrephae (Muesebeck). Doryctobracon areolatus was collected on Anastrepha fraterculus (Wied), A. obliqua (Macquart) and A. amita Zucchi, and was found associated with the largest number of fruit fly host plant species (26), being recorded for the first time in fruits of Clausena lansium and Cryptocarya aschersoniana. This species was the most common, occurring in most of the sampled localities, totaling 77.5 percent of all parasitoids collected. Doryctobracon brasiliensis was associated only with A. fraterculus and recorded, for the first time, in Japanese plum (Prunus salicina). It was not possible to associate the remaining braconids to the fruit fly species. Opius bellus was also reared from larvae in C. aschersoniana. The natural parasitism percentage ranged from < 1 percent to 40 percent.

A total of 2,630 braconids from Anastrephaspp. were recovered in four locations oftwo counties(Manaus and Iranduba) in Amazonas State, Brazil. The parasitoids belong to five species. Opiussp. was the predominant species, showing the highest frequency in the downtown region ofManaus. On the other hand, Doryctobracon areolatus(Szépligeti, 1911) was the predominant species in the countryside. For the faunistic analysis, each collecting site was considered a community. The coefficient of similarity between communities varied from 82 to 100%.
Foram coletados 2 630 parasìtóides de Anastrephaspp., pertencentes a cinco espécies de Braconidae, em quatro locais de dois municípios do Estado do Amazonas. Optussp. foi a espécie predominante no estudo, ocorrendo com maior freqüência na área urbana de Manaus. Doryctobracon areolatus(Szépligeti, 1911) foi a espécie predominante nas áreas rurais. As comunidades foram delimitadas e caracterizadas através de índices faunísticos. As comunidades apresentaram quocientes de similaridade entre 82 e 100%.
