拟金彩蝇属小志并记一新种(双翅目:丽蝇科:鼻蝇亚科)

A NOTE ON THE GENUS Metalliopsis TOWNSEND WITH DESCRIPTION OF A NEW SPECIES(DIPTERA:CALLIPHORIDAE)

拟金彩蝇属(Metalliopsis)曾被多数学者列为金彩蝇属(Metallea)的同物异名,而两属据以描述的模式种都是独模,又都是雌性,之后虽补记雄性,但一直未见到明确的雄性尾器描述。Peris(1952)对本属进行整理时,也未能对雄性外生殖器开展研究,仅把这一大类外形近似的种因都在前胸侧板中央凹陷有黄色纤毛而作为本属的关键特征。作者承大英博物馆 A.C.Pont 博士惠借曾经 Peris 在1952年鉴定为 Metallea notata Wulp 的爪哇产 1(?),经解剖该(?)性外生殖器后发现,本种尾叶宽大,且不愈合,侧尾叶瘦长,与我国的种类显著不同,而类似于鼻彩蝇属的尾器类型。作者还检视了 James 于1964所订的Metallea setosa(Townsend)(?)性尾嚣及 Metallea setiventris James,1964的描述,

The present paper deals with a systematic revision of the genus Metal- liopsis.As a result,a list of 6 species is arranged.Among them one species is considered to be new to science. Comparing with the genitalia,genus Metalliopsis is quite different from Metallea,especially in male genitalia,which is detailed in Chinese text. A descriction of the new species is given. Metalliopsis inflata,sp.nov.(Figs.1-2) ♀:Body length 9mm.Well resembling M.ciliilunula(Fang et Fan, 1985),but it is distinguishable from the latter by the dilated 3rd antennal segment and absence of black hairs on the epiproct. Holotype ,Mengang,Yunnan;Paratypes:2♀♀,Guangze,Fujian; 1,Kunming,Yunnan,China. The holotype is kept in the Institute of Zoology,Academia Sinica,Bei- jing.
