Osteochilotrema malayae gen. nov. sp. nov. (Osteochilotrematinae subfam. nov.) from the intestine of Osteochilus hasselti in Malaysia is described. It is characterized mainly by the symmetrical extracaecal testes and the structure of the male terminal ducts. Protocladorchis pangasii is reported from Pangasius pangasius, Barbus daruphani, B. tambroides and from Malaysia for the first time. It is redescribed and the generic diagnosis amended. Helostomatis indica is reported from O. hasselti in Malaysia, both new records. The subfamily and generic diagnoses are amended. Orientodiscus jumnai was recovered from new hosts, B. tambroides and P. micronemus, and is new for Malaysia. 相似文献

In Japan, dominant parasitoids attacking frugivorous Drosophilidae species were Asobara (Braconidae, Alysiinae), Leptopilina, and Ganaspis species (Figitidae, Eucoilinae). Asobara japonica was found throughout Japan, and its populations in the main islands of Japan were parthenogenetic whereas those in the subtropical islands were sexually reproducing. Other parasitoids showed rather restricted distributions; A.tabida, A. rossica, A. rufescens, and Leptopilina heterotoma occurred mainly in northern to central parts of the main islands, Ganaspis xanthopoda from central to southern parts of the main islands, A. leveri in a southern part of the main islands, and A. pleuralis, L. victoriae, and Ganaspis sp. mainly in the subtropical islands. Their major hosts were species of the D. melanogaster species group in the main islands, and species of the D. melanogaster, immigrans, and polychaeta species groups in the subtropical islands. Host use considerably varied among parasitoid species, especially in the subtropical islands. 相似文献

The multiply-arched, apical quarter to half of the ovipositors of Zaglyptogastra species are capable of flexing ventrally through up to 180°. Flexion is achieved by ventral protrusion of the lower ovipositor valves relative to the upper one, an action which juxtaposes swollen lower valve sections with weak concave narrowings of the upper valve. The structural modifications associated with this flexion mechanism are described and similar ovipositor features are illustrated for the cremastine ichneumonid genus Pristomerus. 相似文献

Characters previously used to distinguish the braconid wasp subfamily Doryctinae show considerable variation. Here we illustrate three new female external adult characters that will facilitate recognition of doryctines and allow precise definition of the subfamily. The new characters are a distinctively shaped apex to the dorsal ovipositor valve, a modified serration structure of the lower ovipositor valve, and a particularly heavily sclerotized ovipositor apex. As a result of finding additional synapomorphies linking the Ypsistocerinae with the Doryctinae, the former group is reduced in rank to a tribe within the latter. 相似文献

Tatochila autodice and T. blanchardii, common native ‘cabbage butterflies’ whose combined range covers most of the southern half of South America, intergrade in the only region where they are known to be in contact—north-western Argentine Patagonia. The zone of intergradation is centred east of the Hua Hum and nearby low passes, with decreasing influence of the Chilean blanchardii both northwards and southwards. Larvae and pupae from the zone display some phenotypic traits never observed elsewhere. The zone is largely concordant with one in which three members of the Tatochila sterodice species-group are also hybridizing. 相似文献

An illustrated key is provided to the African species of the braconine wasp genus (Zaglyptogastra Ashmead. Four new species are described: Z. afenestrata sp. nov. from Ruanda, Z. levisulcata sp. nov. from Uganda, Z. tenuicauda sp. nov. from Angola, Congo and Zaire, and Z. virgulivena sp. nov. from Zaire. A replacement name, Z. caudatula nom. nov. is proposed for Calliidia caudata Szépligeti, 1914b. Six new synonymies are proposed: Zaglyptogastra basalis (Szépligeti; 1914) (= Z. equitator (Wiedemann, 1824)); Z. leucogaster (Cameron, 1909a) (= Z. nigripennis (Szépligeti, 1908)); Z. stanleyi (Cameron, 1912), Z. maxima (Szépligeti, 1914b), Z. eleganta (Shenefelt, 1978) and Z. tomentosa (Fahringer, 1931) (= Z. tincticanaliculata (Cameron, 1912)). Notes are provided on the African species and species groups. A checklist of world species is given. 相似文献
