山东莱阳盆地早白垩世扁足蝇科一个新亚科（昆虫纲:双翅目）

本文记述山东莱阳盆地早白垩世莱阳组（K1l3）的扁足蝇科的1个新亚科—中国盗蝇亚科（Sinotestinae subfam.nov.）.新亚科以其Sc很长,D很小,短于b1,M1与M2呈叉形等等特征区别于其它两个亚科—扁足蝇亚科（Platypezinae）和小神蝇亚科（Microsaniinae）;与此同时,它又兼有上述两个亚科的某些特征;在地史分布上又是早期出现的独特新类群,在分类上应有它本身的位置.文中并将含昆虫化石的地层剖面作了简要的描述.

SINOLESTINAE,AN EARLY CRETACEOUS NEW SUBFAMILY OF PLATYPEZIDAE (INSECTA:DIPTERA) FROM LAIYANG BASIN,SHANDONG PROVINCE

A new subfamily with a new genus and species of Platypezidae (Inse-cta,Diptera)collected from the 3rd-Member of the Early Cretaceous Laiyang Formation (K1l3)of the Laiyang Basin in the Laiyang County of Shandong province is recorded and described here together with the stratigraphic section.Sinolestinae subfam. nov. Body small, Sc very long, reaching beyond the mid-wing, Discus (D) usually short and smaller than the b1, M branching near the mid-wing, with furcate branches.Sinolesta gen. nov. Body oval, colored black, abdomen visible with 8 seg-ments, the first joint of the Tar longer than other joints; D short, smaller than the b1, but it is somewhat equal to the b2, wing broad, with rounded apex, distinctly differing from the long wing and its angular apex in other genera of the Platypezidae. This new genus includes new only the type spe-cies; Sinolesta Lata g.s.n.
