Okubasca Dworakowska，1982，以前被认为是Empoasca Walsh，1862的一个亚属，现在被提升为一个独立的属。本文记述并图解了中国发现的大叶蜂两新种：旋卷大叶蜂于洋种。新种：副卡氏奥库巴斯虫Okubasca paracalvata于洋sp.11月旋卷大头鱼的肛干长度与前房相仿，但不同之处在于侧位有厚度均匀的肛管，肛管突起笔直，面部多为黑色。大头金鱼与大头金鱼的外形相似，但不同之处在于背侧有板层肿胀和小齿，顶端前缘呈圆形。
Okubasca Dworakowska, 1982, formerly treated as a subgenus of Empoasca Walsh, 1862, is elevated to status as a separate genus. Two new species of Okubasca from China are described and illustrated: Okubasca convoluta Yu Yang sp. nov.; Okubasca paracalvata Yu Yang sp. nov. Okubasca convoluta is similar to O. okubella in having the aedeagal shaft about as long as the preatrium but differs in having the aedeagus of uniform thickness in lateral view, the anal tube process straight and the face mostly black. Okubasca paracalvata resembles Okubasca calvata in aedeagal shape, but differs in having a lamellar swelling and a small tooth on the dorsal side of the aedeagus, and the vertex anterior margin rounded.
