Provedor de dados: Naturalis Digital Academic Repository
Autores: Achterberg, C. van; Yang, Z.-q.
Three new species of the genera Megischus Brullé and Stephanus Jurine from China (Hymenoptera: Stephanoidea: Stephanidae) are described, illustrated and keyed. Megischus ptosimae Chao, 1964, from Fujian is redescribed and the specimen from India described as M. ptosimae Chao by van Achterberg (2002) is renamed as M. alveolifer spec. nov. and the Malaysian specimen of M. ducalis Westwood listed by van Achterberg (2002) is described as M. ducaloides spec. nov. M. ducalis Westwood, 1851, is reported for the first time from Cambodia, which is the first report after its description. A key to world species of the genus Stephanus is provided.

(type species: Stephanus elliotti Ceballos, 1926, from Madagascar), with subgenus Comnatopus nov. (type species: Stephanus comma Morley, 1917, from the African continent), Afromegischus gen. nov. (type species: Stephanus pachylomerus Schletterer, 1889, from the African continent) and Pseudomegischus gen. nov. (type species: Stephanus sulcifrons Schletterer, 1889), with the nominate subgenus in the Indo-Australian region and subgenus Callomegischus nov.

Autores: Aguiar,Alexandre Pires.
Four additional species are included in the genus Hemistephanus: H. villosus (Kieffer) comb. n. and H. colombiensis (Ceballos) comb. n., transferred from Megischus and redescribed, and H. costaricensis sp. n. and H. stenogulatus sp. n., described as new; H. artiosulcatus Aguiar is proposed as a junior synonym of H. villosus Kieffer. The males of H. arctatus, H. colombiensis, H. submaculatus, and H. villosus are described for the first time. Much new or additional morphometric data is incorporated and discussed for these species and for H. carinatus, H. erugatus, H. erythrocephalus, H. limpidipennis, H. orfilanus, H. ruficeps, and H. velutinus. New geographical records are presented for all mentioned species and for H. cylindricus. Errata for publications...
