CommentComparisons: L. bibonius, L. muelleri, and L. dumerili, possess transverse light bands throughout the body and tail. However, the number of bands in L. bibonius is greater than in L. dumerili and less than those of L. muelleri. These differences correspond to the breadth of dark interspace between bands; the space is widest in L. dumerili, followed by L. bibonius, and narrowest in L. muelleri (Table 1). In L. muelleri, each interspace is usually divided into three parts by extensions of neighboring pale bands, and each has a prominent light margin. Consequently, the dorsal pattern of this species has a median row of large dark spots and two lateral rows of smaller spots against a light brown ground color. Interspaces in L. bibonius and L. dumerili, on the other hand, are always continuous, and pale margins are not prominent or wholly lacking (Figs. 6, 12). Adults ofL. muelleri and L. dumerili have more or less developed keels in the posterior dorsal scales (juveniles of these species lack them). These keels are not evident in adults of L. alcalai, L. chrysoprateros, and L. solivagus (this character state remains unknown for L. bibonius). (Ota & Ross 1994) 
EtymologyThe species is named after French herpetologist A.M.C. Duméril.
