食蚜蝇科的分类系统及其研究进展

综述了食蚜蝇科的分类系统及其研究进展。林奈未能正确地区分出食蚜蝇类昆虫 ,将当时已知的大约 3 7种食蚜蝇归入家蝇属Musca中。Fabricius首次建立的食蚜蝇属Syrphus包括了当时已知的大部分食蚜蝇种类和一些非食蚜蝇种类 ,一些真正的食蚜蝇仍保留在家蝇属Musca及其它属中。MosesHarris是第 1位将食蚜蝇与双翅目其它类群分开的学者。Latreille首次建立食蚜蝇科Syrphiae。Fall啨ｎ以“Syrphici”作为食蚜蝇科的科名 ,现代食蚜蝇科的名称“Syrphidae”由Leach提出。目前 ,多数学者认为食蚜蝇科隶属于双翅目的环裂亚目Cyclorrhapha、无缝组Aschiza ,头蝇科Pipunculidae是其姊妹群 ,二者构成食蚜蝇总科Syrphiodea。在分类系统方面 ,Rondani首次将食蚜蝇科分为 5个亚科。Lioy第 1次依据幼虫摄食习性将食蚜蝇划分为 5个群 (group) ,并对Eristaliti群进行了再划分。Schiner依据径中横脉 (r m)的位置将食蚜蝇科分为 2个类群 ,将食蚜蝇科分为 8个亚科。Williston将食蚜蝇科划分为 3个亚科 ,包括1 4个族。Verrall在Schiner和Williston系统的基础上 ,提出分 7个亚科的分类系统 ,这一系统得到其后学者的认可和引用 ,如Efflatoun、Brunetti、Ferguson等。Bezzi也引用Verrall的系统 ,但以齿腿蚜蝇亚科Merodontinae取代

DESCRIPTION OF A NEW SPECIES OF PHYLLIDIOPSIS BERGH (NUDIBRANCHIA: DORIDOIDEA: PHYLLIDIIDAE) FROM THE TROPICAL WESTERN PACIFIC, WITH COMMENTS ON THE ATLANTIC SPECIES

A new species of phyllidiid nudibranch, Phyllidiopsis shireenae,is described. The new species has a middorsal crest insteadof being flattened dorso-ventrally like most phyllidiids. Itsbody is a very pale shade of pink with black bands, and itsrhinophores are salmon pink. The anatomy of the alimentary systemand reproductive system are described. Characters originallyused by Bergh (1875) to differentiate the genus are supportedby this new species. Phyllidiopsis shi-reenae is presently knownfrom coral reef habitats in the extreme western Pacific Ocean.A review of the taxonomic status of the Atlantic specis of Phyllidiopsisis required. ^*Present address: Australian Biological and Environmental Survey.Australian National Parks and Wildlife Service, GPO Box 1383,Canberra. ACT 2601. Australia. (Received 15 August 1989; accepted 8 January 1990)     

A NEW SPECIES OF OXYCHILUS FROM THE LIGURIAN APENNINES (ITALY) (PULMONATA: ZONITIDAE)

A new species of Oxychilus Fitzinger from the Ligurian Apennines(Italy) is described. The new species is particularly characterizedby its penial complex which has a very slender proximal peniswith variable inner sculpture and a widened distal penis. Theproximal penis inner structure consists of a series of longitudinalpleats which may often be crenulated, undulated or fragmentedto form rows of papillae, providing new evidence to supportthe opinion that this is not a valid diagnostic character forseparating Oxychilus into the nominal subgenus and OrtiziusForcart. Consequently Ortizius is herein proposed as a juniorsynonym of Oxychilus s. str. (Received 5 July 1990; accepted 4 March 1991)     

REVISION OF THE GENUS ACAVUS FROM SRI LANKA (GASTROPODA: ACAVIDAE)

The genus Acavus from Sri Lanka includes three species, Acavushaemastoma (Linnaeus), Acavus superbus (L. Pfeiffer) and Acavusphoenix (L. Pfeiffer) with two subspecies, Acavus phoenix phoenix(L. Pfeiffer) and Acavus phoenix castaneus new subspecies.The conchological and anatomical differences between these species,as well as their intraspecific variation are described. Theirdistribution is shown on maps and all locality records are listed.The presence of extensive intraspecific polymorphism, the developmentof geographical subspecies and the presumable hybridizationbetween some species show that the Acavus species are not isolatedrelict species, but that speciation is in progress and thatthe radiation of the Acavus species is probably much youngerthan the radiation of the acavid genera. The three Acavus speciesare not acutely endangered at present. In contrast to manyother land snails, there is no risk of a rapid decline of theAcavus species due to deforestation, because these species alsooccur in synanthropic habitats.
