Abstract The Palaearctic delphacids ,Idiobregma unicarinata Anufriev ,is reported for the first time from China bad on the specimens collected from
Jilin (N .E .China ).A redescription of brachypterous adults is provided and male genitalia are reillustrated .The relationship of this genus with related genera is discusd .

2018四级答案1 Introduction
The monotypic delphacid genus Idiobregma was established by Anufriev in 1972for I .unicarinata Anufriev from Sikhote Alin Region ,USSR .Anufriev &Emeljanov (1988)reillustrated the type species ,and provided a key to the single species ,which is currently known to occur only in the Palaearctic Region .This genus and the species were discovered in the specimens collected from Jilin Province in Northeast China .This opportunity is taken to redescribe the genus and discuss its relationship with other genera of the tribe Delphacini in the Chine fauna .
2 Material and Methods
This study is bad on recent collections made by the graduate students of the Entomological Mu
um ,Northwest A &F University (N WAFU ).External body characters were examined under a Metic stereomicroscope ,and illustrations of the male genitalia were made using an OL Y MPUS PM 210AD microscope ,and the external figures were drawn using Leica M Z 1215steromicroscope with built in drawing tube .The body measurements are from apex of vertex to tip of abdomen .The morphological terminology ud in this description follows Ding (2006).All measurements are in millimeters (mm ).
3 Genus Idiobregma Anufriev
Idiobregma Anufriev ,1972:612.reus
Type species :Idiobregma unicarinata Anufriev ,1972,by monotypy .
Generic diagnosis .Body brownish ,medium 2sized .Head short ,relatively broad ,fastigium obtuly rounded ,median carina of frons forked at ba .Calcar tectiform ,without distinct teeth on inner margin .Male genitalia with parameres divergent .Genital diaphragm broad .Aedeagus tubular ,with oblique row of teeth subapically .Suspensorium ring 2like ventrally .Male anal gment ring 2like ,ventrolateral angles strongly produced ventrad into two process slightly parated from each other .
Remarks .The genus Idiobregma is similar to Megadelphax Wagner and Muirodelphax Wagner as given by Ding (2006),but differs from them by the shorter and broader head and by the calcar without distinct teeth on inner margin .It also differs from Muirodelphax by the strongly produced process of the anal gment .This genus is a new record for China .Idiobregma unicarinata Anufriev ,1972(Figs 11212)
