白垩纪缅甸琥珀双翅螳蛉科一新属新种(昆虫纲:脉翅目)

A NEW GENUS AND SPECIES OF DIPTEROMANTISPIDAE(INSECTA:NEUROPTERA)FROM CRETACEOUS BURMESE AMBER

基于三枚晚白垩世Cenomanian期早期缅甸琥珀化石标本,记述了脉翅目双翅螳蛉科Dipteromantispidae一新属新种:卓德曲双翅螳蛉Kurtodipteromantispa zhuodei gen.etsp.nov.。新种与格氏棒翅螳蛉Halteriomantispa grimaldii Liu et al.,2016相似,但以下特征区别于后者:1)前翅无色斑;2)前翅ScP端部在scp-ra横脉处具明显弯折,不平滑;3)前翅RP至少具1末端分叉的分支;4)雌外生殖器肛上板与第9背板融合,第9生殖基节近半圆形,末端无近三角形突起。此外,描述并讨论了新属雌外生殖器的形态结构。

A new genus with a new species Kurtodipteromantispa zhuodei gen.et sp.nov.(Neuroptera:Dipteromantispidae)is described based on three specimens from late Cretaceous(earliest Cenomanian)Burmese amber.The new species is similar to Halteriomantispa Liu et al.,2016,while the former could be distinguished from the latter by these characters as follow:1)forewing without pigmented spots;2)distal portion of ScP distinctly curved at scp-ra,not smooth;3)RP with at least one branch forked distally;4)ectoprocts fused with tergum 9,and gonocoxites 9 nearly semicircular,apically without subtriangular projection.Additionally,female genitalia of the new genus are described and discussed.
