|Distribution||Yemen (Socotra Island).|
Type locality: Jena-agahan, 1200-2500 ft.; Dahamis, 350 ft.; and Homhil, 1500-2500 ft., Socotra.
|Types||Syntypes: BMNH 19220.127.116.11-76, 1918.104.22.168-91, 1922.214.171.124-85.|
|Diagnosis||Diagnosis: L. macrurus differs from L. filiformis in the proportional bigger diameter at midbody and the strong caudal spine. According to Hahn (1978) L. wilsoni differs from L. macrurus in the following features: a hooked snout, divided occipitals (?) [from RÖSLER & WRANIK 2006]. |
Description: “This species is much stouter than L. filiformis and wilsoni measuring from 107 to 165 mm, and having horizontal diameters of 3.0 to 4.2 mm. Total length divided by diameter equals 35.5 to 45.0 times (mean 39.6). Head slightly broader than neck; snout prominently protruding to an obtuse point anteriorly, and hooked in lateral profile, the preoral portion of rostral being concave. Rostral does not reach level of the eye posteriorly; rostral approximately one-half the width of the head at its widest point; nasal completely divided, with a corner of the lower portion visible in dorsal view; upper portion of nasal about one-half the width of the ocular; single, small anterior supralabial between the nasal and ocular, larger proportionately than that of L. filiformis; ocular reaches lip; eyes distinct; supraoculars about the same size as prefrontal and frontal; parietal single, occipital divided (BMNH 19126.96.36.199 has an undivided occipital on the right side). Posterior supralabial large, but does not reach eye level dorsally; no mental present; five infralabials present. Total dorsals 257-277, mean 268.9; 14 scale rows around body; tail terminating in an acute point after a long even taper; ten scale rows around middle of tail in all specimens examined; tail length about twice as long as in filiformis, going into total length 5.4 to 6.5 times (mean 5.9); subcaudals 43 to 54 (mean 48.6). The five dorsal-most scale rows are pigmented with a diffuse dark brown pigment; the nine ventral and lateral scale rows are light brown; no sharp line of pigment demarcation is present.” (Hahn 1978)
