表6 树蟋科（Oecanthidae）与蟋蟀科（Gryllidae）的主要差异

**头部**
树蟋科（Oecanthidae）新定义：体表被短柔毛；触角柄节与头顶等宽或更宽；背面观头顶长大于宽或长宽相等；中单眼位于背面；侧单眼位于背面；整体体表光滑。
蟋蟀科（Gryllidae）新定义：触角柄节窄于头顶；背面观头顶通常宽大于长；中单眼位于面部；侧单眼通常位于额面。

**足**
树蟋科（Oecanthidae）新定义：后足胫节内端距长度为外端距的3倍及以上；前、中足的第一、第二跗分节等长；前、中足的第二跗分节扁平；具爪垫（pulvillum）。
蟋蟀科（Gryllidae）新定义：后足胫节内端距略长于外端距；前、中足的第一跗分节长于第二跗分节；前、中足的第二跗分节不扁平；无爪垫（pulvillum）（除蛛蟋亚科（Eneopterinae）外）。

**雄性外生殖器**
树蟋科（Oecanthidae）新定义：外阳茎弧不完整（除Cearacesaini族外）；中脊突（MedLophi）若存在则呈两叶状（除Veredatrypa属外）。
蟋蟀科（Gryllidae）新定义：外阳茎弧完整（除陆蟋亚科（Landrevinae）外）；中脊突（MedLophi）若存在则为单叶状。

**产卵器**
树蟋科（Oecanthidae）新定义：产卵器端部侧面具锯齿或突起（除突蛉蟋亚科（Euscyrtinae）外）。
蟋蟀科（Gryllidae）新定义：产卵器端部侧面光滑，无突起。

**栖息环境**
树蟋科（Oecanthidae）新定义：栖息于多种植被类型，从草本植物至林冠层（除Prognathogryllus类群的部分物种外）。
蟋蟀科（Gryllidae）新定义：栖息于植被、树皮下方、枯落物层、地表及洞穴中。
