Figs. 2 and 3 Holotype KUZ R50922, mature female; Ampijoroa, Ankarafantsika Strict Nature Reserve, north- western Madagascar (16 20'S, 46 48'E: Fig. 1), 100 m; collected by A. Mori, M. Hasegawa, and I. Ikeuchi, 7 November 1999. Paratype KUZ R50823, mature female, from the same locality as the holotype, collected by G. Razafindrakoto, as a "dead on the road" specimen, 11 November 1999. Generic diagnosis The new genus is a member of the subfamily Scincinae (Greer, 1970). It is distinguished from all other taxa in this group by the follow- ing combination of characters in derived states (polarity for each of these characters was inferred as relative to Eumeces, the putative primitive genus of the family: Greer and Broadley, 2000). Body highly elongated (SVL times head length) with 53 presacral vertebrae; original tail slightly longer than SVL; snout pointed, lower jaw counter- sunk; neck indistinguishable externally; body scales smooth and transparent without pig- mentation; 20 longitudinal scale rows at mid- body. Forelimb small (approximately of SVL) with indistinct fingers and four stout claws; no hind limbs, shallow groove in their position in other scincines; prefrontals absent; nasal sharply pointed, triangular, positioned at V-shaped notch of rostral; nostril positioned at anterior tip of nasal; frontonasal as large as frontal; frontoparietal absent; loreal single; supraoculars two; superciliaries and movable lower eyelid absent; eye covered with two oculars; supralabials six; infralabials five, anterior three higher than posterior two; external ear opening covered
