CommentType species: Alexandresaurus camacan RODRIGUES et al. 2007 is the type species of the genus Alexandresaurus RODRIGUES et al. 2007.

Definition (genus Alexandresaurus): A large and slightly elongate gymnophthalmid (maximum SVL 70 mm) with distinctive ear opening and eyelid, large tail (1.63%–2.36% SVL), and slender pentadactyl limbs; first toe lacking a claw. Frontonasal single; prefrontals, frontoparietals, parietals, and interparietals present. Parietals and interparietal longer than wide. Collar fold absent. Two pairs of genials and three supraoculars. Dorsal scales anteriorly smooth, isodiametric or subrectangular in occipital region, becoming progressively narrower, more elongate and rounded toward arm level and then lanceolate, strongly keeled, with lateral sides almost juxtaposed. Occipitals absent. Ventrals longer than wide, smooth, in four regular transverse series identical in size. Males with a continuous series of very conspicuous pores with no gap between preanal and femoral; pores absent in females. Hemipenis without evident bilobation, sulcus spermaticus single, marginated by a naked area which is also present on the opposite side of sulcus. Between naked areas two symmetrical series of continuous transverse rows of comb-like flounces with minute spines or irregular tooth-like structures. A series of enlarged spines near the base of hemipenis.

DIAGNOSIS of the species: A gymnophthalmid with ear openings and eyelids, and slender pentadactyl limbs lacking the claw on first toe. Frontonasal single; prefrontals, frontoparietals, parietals, and interparietals present. Parietals longer than wide. Collar fold absent. Two pairs of genials; three supraoculars. Dorsal scales in 30–38 rows, anteriorly smooth, isodiametric or subrectangular in occipital region, becoming progressively narrower, more elongate and rounded toward the arm, and posterior to the arm becoming more lanceolate, strongly keeled, with lateral sides almost juxtaposed. Occipitals absent. Ventrals longer than wide, smooth, in four regular longitudinal and 15–19 transverse rows, identical in size. Scales around body 29–35; 11–15 and 16–20 infradigital lamellae under finger IV and toe IV respectively. Males with a series of 20–25 very conspicuous pores without gap between preanal and femoral; pores absent in females. 
EtymologyETYMOLOGY: A homage to the Brazilian naturalist Alexandre Rodrigues Ferreira, born in Salvador, state of Bahia, as a recognition for his effort to document the natural history of Brazil at the end of the 18th century. The specific epithet is a homage to the extinct Camacan Indians, a Botocudo group who lived in the exuberant forests of Bahia from north of Rio Pardo to Ilhéus.
