片吉蛉属新种及新记录种(直翅目:蟋蟀科)

NEW SPECIES AND NEW RECORDS OF THE GENUS TRULJALIA (ORTHOPTERA: GRYLLIDAE) FROM CHINA

片古蛉属Truljalia隶属于蟋蟀科Gryllidae突额吉蛉亚科Podoscirtnae,此属是俄罗斯的Gorochov 1985年以分布于我国广东的柑桔吉岭Calyptotrypus citri Bey-Bienko 1956为模式种建立的,并将我国的梨吉蛉Madasumma hibinonis Matsumura和分布于东南亚一带的Calyptotrypus属的3个种移至此属,同时指出Calyptotrypus for-ceos Saussure分类地位不明确,但可能也属于此属。我们对现有的这一属标本进行了分类研究,确认Calyptotrypus forceps Saussure应属于Truljalia属,并鉴定出3新种,1中国新记录种,现报道于后。新种模式标本保存于中国农业科学院植物保护研究所标本馆。
