记述发现于浙江龙王山保护区的瘿蚊科(Cecidomyiidae)新属新种一中华奇瘿蚊Thaumacecidomyiasinica Yandg,g.et sp.n.,讨论瘿蚊科的高级分类阶元,建立奇瘿蚊新亚科(Thaumacecidomyiinae,subfam.n.)。
A large wonderful gall midge discovered from Zhejiang has been described as a new genus and new species herein. The type specimens kept in the Insect Collections of Beijing Agri-cultural University.
Thaumacecidomyia gen. nov.
Diagnasis: Male桝ntenna with 2+14 segments, flagellar segment covered long bristles and with long distal stem. Palpus consisting of 4 segments. Ocellus lecking. Legs slender, the first tarsal segment very shorter than second, claw with basal tooth. Wing with complate vena-tion, R5 joining the costa at wing apex, r?m similer to Rs, M1+2 forked and M3+4 arisen from base of M. Cu simple. Genitalia with gonocoxite separate ventrally, gonostylus short and stout. Female桹vipositor long and telescopic protrusible, cerci much sclerotized.
Type species: The following new species.
Thaumacecidomyia sinica, sp. nor. Holotype(?), allolype(?), Zhejiang Prov. Anjico. Longwangshan (119. 6癊,30. 6癗), 1996 梀?14 collected by Dr. Wu Hong, prescrred in alcohol.
Male (Fig. 1) Length of body 6mm. length of wing 4mm, width of wing 1. 5mm. Body dark brown, wing pale smoke brown, This large dark species is characterized as the diagnotic character of the genus and text ?figures 1 ?3. the genitalia as show in figs. 5 and 6. Female much larger than male, Ingth of body about 8mm, length of wing 6mm. width about 2mm. An tenna broken, only the basal 3 segments is left over (fig. 4) the first flagellar segment as long as head length, the distal stem about as long as this segment width. Abdomen (Fig. 7) very stout and darken, the basal four segments fused, only 5 spiraculae on the pale latacoria. Ovipositor (Fig. 8) telescope, cerci (Fig. g) sclerotizcd and armed a series of sharp teeth. Abdomen full of eggs. The egg (Fig. 10) sausage -like and with a micropyle protuberance distally.
This new taxa is so peculiar characterized by short metatarsus and complate venation exist simultaneously, and can't include to the subfamilies Lcstremiinae or Porricondylinae and Ce-cidomyiinae obviously. Therefore a new subfamily Thaumacecidomyimae must be erected for the Thaumacecidomyia g. et sp. n. necessary. Survey the higher classification history of Cc-cidomyiidae, a phylogenetic tree by the venation chiefly (Fig. 11) demonstrating this new sub-family.
