The almost continuous range of variation in external digital characters, especially among the west Asian and Somali species of the Hemidactylus group of geckos has long been recognized, and has resulted in the establishment of several different, largely arbitrary, generic arrangements (see Parker, 1942 for a discussion). Thus, while division of the scansors is generally characteristic of the genus Hemidactylus, there are many species that express this trait only marginally. Russell (1976: Fig. 14) indicated this potential continuity in scansor form, from undivided to completely divided, by. FIG. 2. a. Ventral aspect of the right pes of Dravidogecko anamallensis, BMNH b.
