中国刻纹牙甲属Thysanarthria一新种及越南新记录T.bifida(鞘翅目:牙甲科)
记述采自中国湖南和广东的牙甲科1新种——罕刻纹牙甲Thysanarthria rara sp.nov.,提供了中国该属已知种的检索表.本新种与中国台湾省的楚氏刻纹牙甲T.chui Fiká(c)ek& Liu,2019相近,可以通过以下特征相区别:鞘翅颜色较浅;头和前胸背板具明显皮革状纹;雄性外生殖器基叶在侧叶基部明显加宽,侧叶基部外缘不强烈向外扩展,中部1/3适度向外扩展(楚氏刻纹牙甲T.chui雄性外生殖器见Fiká(c)ek&Liu.2019: figs 8A-E);新种与分布在云南的查氏刻纹牙甲T.championi (Knisch,1924)也可通过雄性外生殖器特征相区别(查氏刻纹牙甲T.championi雄性外生殖器基叶不明显宽于侧叶基部,侧叶外缘几乎均匀弧形,端部1/4略波曲Fiká(c)ek&Liu,2019: figs 7A-E).文章还首次记录了越南(Tonkin,Hoa-Binh)的凹刻纹牙甲T.bifida Fiká(c)ek& Liu,2019.
