记述了白屈菜属Lycodon（L.）阿尔卡莱湖比博纽斯湖chrysoprateros和L. solivagus）描述于菲律宾北方的巴坦、卡米金、达卢皮里和吕宋群岛。这些种与L. dumerili和L. muelleri，但不同于其他菲律宾同源物，有一个稍微拱形的上颌骨，中间分裂的鼻，和一个完整的肛门盾。Lycodon alcalai和L. chrysoprateros不同于所有其他菲律宾物种的白狼缺乏横向轻带的所有身体和尾巴。Lycodon alcalai与L. chrysoprateros的腹鳞多于200片（L. chrysoprateros）。Lycodon bibonius与菲律宾其他Lycodon物种的不同之处在于，身体和尾巴上分别有22-25条和16-21条浅色条纹; L. Solivagus的特征是仅在身体的前四分之三上出现13-14条苍白带。
Four new species of the genus Lycodon (L. alcalai, L. bibonius, L. chrysoprateros, and L. solivagus) are described from Batan, Camiguin, Dalupiri, and Luzon islands of the northern Philippines. These species are similar to L. dumerili and L. muelleri but distinct from other Philippine congeners by having a slightly arched maxilla, medially divided nasal, and an entire anal shield. Lycodon alcalai and L. chrysoprateros differ from all other Philippine species of Lycodon in lacking transverse light bands on all of the body and tail. Lycodon alcalai differs from L. chrysoprateros in having more than 200 ventral scales (less than 195 in L. chrysoprateros). Lycodon bibonius is distinct from other Lycodon species in the Philippines in having 22-25 and 16-21 pale bands on the body and tail, respectively; L. solivagus is characterized by 13-14 pale bands occurring only on the anterior three-fourths of the body.
