Redescriptions of Lectotypes. The lectotype of Lygosoma melanopogon (MNHN 1245; Figs. 1 A – B, 2) has the following character states: dorsal lobe of rostral with a slightly concave posterior border; nasals broadly separated; nostril central in nasal; supranasals absent; prefrontals in broad contact; supraoculars seven, first four in contact with frontal, last four in contact with frontoparietal; supraciliaries 14 / 14, first separated from frontal; frontoparietals in broad median contact; parietal eye spot at junction of second third and last third of interparietal length; parietals in broad contact behind interparietal; anterior loreal taller than wide and taller than posterior loreal; posterior loreal squarish, a little wider than tall, and narrowest ventrally; presuboculars two, first largest, last interdigitating with supralabials; suboculars 4 / 3; postsuboculars 7 / 8, first interdigitating with supralabials; supralabials seven, fifth below centre of eye, last two each divided into an anteroventral and a posterodorsal scale; primary temporals two, anterodorsal and posteroventral, the more dorsal very small; lower secondary temporal single, overlapping upper secondary temporal; scales bordering parietals between upper secondary temporals eight; ear with six low rounded lobules along anterior margin; infralabials 8 / 7, only first contacting postmental; first pair of chin shields in median contact; second pair medially separated by a single scale; third pair of chin shields separated by three scales; all chin shields laterally contacting infralabials. Longitudinal scale rows at midbody 43; scales in a paravertebral row (A) 71, not broader than adjacent dorsal scales; dorsal scales finely striate, laterally and ventrally becoming smooth; median pair of precloacal scales enlarged, laterally overlapping adjacent precloacals; lamellae below fourth toe (A) 30 / 29; scales above fourth toe four at level of metatarsophalangeal joint, decreasing distally so that last two scales single. SVL 60 mm; AGL 27 mm; tail regenerated; FLL 22 mm; HLL 37 mm; HL 13.1 mm; HW 9.5 mm; HL 7.6 mm. The male lectotype of Lygosoma florense (ZMA 11060; Figs. 4 – 5) has the following differences in scalation and morphometrics from those described for the lectotype of L. melanopogon: posteriormost supraocular does not contact frontoparietals; supraciliaries 13 / 13; frontoparietals partly fused posteriorly; parietal eye spot slightly posterior to centre of interparietal; posteriormost presubocular barely interdigitating with supralabials; suboculars 5 / 4; postsuboculars 8 / 6; lower secondary temporal overlapped by upper secondary temporal (overlap pattern as for the lectotype of L. melanopogon in remainder of type series); ear with seven conical lobules along anterior margin; infralabials 8 / 9. Longitudinal scale rows at midbody 46; paravertebral scales (A) 84; subdigital lamellae (A) 30 / 34. SVL 68 mm; AGL 32 mm; tail regenerated; FLL 21.5 mm; HLL 37.5 mm; HL 15.8 mm; HW 11.4 mm; HD 9.0 mm. The male lectotype of Lygosoma Kühnei (Figs. 6 – 7) has the following scalational and morphometric characteristics that differ from those described for the lectotype of L. melanopogon: supraciliaries 12 / 13; anterior loreal about same height as posterior loreal; suboculars 3 / 3; postsuboculars 5 / 6; lower secondary temporals two, the upper of the two including the upper portion of the primary temporal; ear with five low rounded lobules along anterior margin; infralabials 7 (on left — right side not counted). Longitudinal scale rows at midbody 40; paravertebral scales (B) 77; subdigital lamellae (B) 31. SVL 66 mm; TL 120 mm; FLL 24 mm; HLL 39 mm. AGL and head measurements not taken.
