Within the family Lernaeopodidae Milne Edwards, 1840 the females of Lernaeopoda spp. are very similar to those of Neoalbionella spp. Contrarily, the male morphology is different enough to allow distinction between species of the two genera. Unfortunately, males are not always attached to collected females and therefore often not described. Hence the validity of some of the Lernaeopoda spp. are still questionable due to incomplete descriptions of the female and no description of the male. Lernaeopoda bivia Leigh-Sharpe, 1930 is an example of an accepted species due to a redescription of the female done in 1986 but without a description of the male. Lernaeopoda bivia has only been reported twice, collected from Schroederichthys bivius (Müller & Henle). Recently, females with attached males were collected from Triakis semifaciata Girard from Inner Cabrillo Beach in southern California. The female morphology of L. bivia is similar to the previous redescription with some additional features and illustrations while the male conforms to the morphology of males of Lernaeopoda spp. The dental formula of males and females of the species of the genus differ with males having one P1, S1 less than females. The structure and armature of the appendages of the three described species of males (L. galei Krøyer, 1837, L. bidiscalis Kane, 1892 and L. bivia) is mostly similar with the tympanal membrane of the three species the most distinctive feature. A key to identify the females of the valid species of Lernaeopoda is provided.
在 1840 年米尔恩-爱德华兹（Milne Edwards）建立的 Lernaeopodidae 科中，Lernaeopoda spp. 的雌性与 Neoalbionella spp. 的雌性非常相似。相反，雄性形态差异足够大，可以区分这两个属的物种。不幸的是，雄性并不总是附着在采集到的雌性上，因此通常不被描述。因此，由于对某些 Lernaeopoda spp. 的雌性描述不完整且没有对雄性的描述，因此它们的有效性仍存在疑问。Lernaeopoda bivia Leigh-Sharpe，1930 是一个被接受的物种的例子，因为 1986 年对其雌性进行了重新描述，但没有对雄性进行描述。Lernaeopoda bivia 仅报告过两次，从 Schroederichthys bivius（Müller & Henle）中采集到。最近，从加利福尼亚州南部的卡布里洛海滩内部的 Triakis semifaciata 中采集到了带有雄性的雌性。L. bivia 的雌性形态与之前的描述相似，但具有一些额外的特征和插图，而雄性则符合 Lernaeopoda spp. 雄性的形态。该属的物种的雄性和雌性的齿式不同，雄性的 P1、S1 比雌性少。三种描述的雄性（L. galei Krøyer，1837、L. bidiscalis Kane，1892 和 L. bivia）的附肢的结构和装备大部分相似，而三种物种的鼓膜是最具特色的特征。提供了一个鉴别有效 Lernaeopoda 物种雌性的关键。
