It also differs from other cercosaurines, except  Centrosaura,  Echinosaura s.s.,  Gelanesaurus,  Neusticurus and  Potamites, in having heterogeneous dorsal scalation. For comparisons among related or similar genera see Figure 9 and Table 5.</p><p>Etymology:  Rheosaurus (gender masculine) is derived from the Greek ρέω, rheo (flow or stream) and σαύρα, saura (lizard), in reference to the riparian habit of this lizard.</p><p>Geographic distribution: Pantepui bioregion of the Guiana Shield, from the vicinity of the Baramita area in north-western Guyana (100 m a.s.l.) to the Wokomung massif in west-central Guyana (Donnelly et al., 2006; Cole et al., 2013).</p><p>Remarks: Donnelly et al. (2006) tentatively allocated  sulcarostrum to  Echinosaura and emphasized that this generic assignment reflected convenience rather than an understanding of the phylogenetic relationships of this species. They also anticipated that its disjunct distribution with respect to other  Echinosaura and the differences in external head morphology, may reflect an independent phylogenetic history.</p></div>	https://treatment.plazi.org/id/285E87F7FFBFBC3A1DA0DD51C2C7FA5A	Public Domain	No known copyright restrictions apply.

Morphological variation among species of  Echinosaura is summarized in Table 2 and 3.</p><p>Echinosaura differs from other cercosaurines, except  Centrosaura,  Gelanesaurus,  Neusticurus,  Potamites and  Rheosaurus, in having heterogeneous dorsal scalation. It differs from the other genera with heterogeneous dorsal scalation in having small or granular, irregular dorsal scales intermixed with tubercular or spine-like scales (vs. small irregular or granular dorsal scales intermixed with large or polygonal keeled scales), several irregular scales on the parietal region (vs. regular scales on parietal region) and usually one pair of large chin shields (vs. usually more than one pair of large chin shields). A comparison of  Echinosaura and closely related and morphologically similar genera is given in Table 5 and Figure 9.</p><p>Etymology: Although not explicitly stated by Boulenger (1890), the name  Echinosaura (gender feminine) is presumably formed from the Ancient Greek ἐχῖνος, echinos (hedgehog or urchin) and σαύρα, saura (lizard) – a spiny lizard.</p><p>Geographic distribution: All species of  Echinosaura are trans-Andean, extending from western Panama to north-western Ecuador. Most species occur in lowlands, but some reach as high as c. 2200 m a.s.l.</p><p>Remarks: Our phylogenetic analysis corroborated the inclusion of the previously not-analysed species  E. palmeri and  E. panamensis in  Echinosaura s.s., as recently hypothesized by Torres-Carvajal et al. (2016).</p></div>	https://treatment.plazi.org/id/285E87F7FFBFBC271EB7DDD6C4E0FD71	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Köhler et al., 2004: 52–60 (original description). Holotype: Male (MHNG 2359.77) from ‘ Las Pampas (=San Francisco de las Pampas, 0° 25’ 60’ S, 78° 25’ 00’ W, 1275 m elevation), Provincia Cotopaxi,  Ecuador’ .</p><p>Diagnosis: The following data are based on the original description and high-quality photographs of specimens deposited at QCAZ (Museo de Zoología, Pontificia Universidad Católica del Ecuador; photographs are available online through www. bioweb.bio).  Echinosaura brachycephala possesses the following characteristics: (1) snout relatively short and rounded; (2) internasal single; (3) frontonasals paired [rarely with 1–4 small irregular scales between the frontonasals and the frontal (‘prefrontals’)]; (4) frontal single (rarely divided); (5) frontoparietals paired; (6) supraoculars three (third supraocular smaller than first and second); (7) supralabials 3–5 (usually four); (8) infralabials three; (9) postmental reduced or absent; (10) chin shields not differentiated; (11) two paravertebral rows of tubercles or spine-like scales, slightly undulating, separated from each other by 4–6 small, irregular scales; (12) tubercular scales forming oblique lines on lateral surface of body; (13) ventral scales keeled, squared (or are rounded squares); (14) subdigital lamellae on the fourth finger 16–23; (15) subdigital lamellae on the fourth toe 23–32; (16) femoral pores per hind limb in males 7–9, in females 1–2; (17) dorsal and lateral surface of tail with small tubercles scattered along each caudal segment (coded as ‘&lt;pattern’); (18) subcaudals per caudal segment four (when tail is not regenerated); (19) dorsum brown or dark brown, relatively uniform, with some clear spots more or less visible; ventral surface of head and neck light brown with several scales bearing white spots, except on the edges near the mouth where there is a darker ground colour with some transverse cream blotches which extend to labial scales; ventral surface of body (including limbs and tail) mainly light brown spotted with dark brown and cream.</p><p>Combination of these characteristics distinguishes  Echinosaura brachycephala from its congeners. In addition, the distinctiveness of  E. brachycephala and its sister-species,  E. horrida (Fig. 2), is further corroborated by uncorrected pairwise distances of 18.8% in ND4 and 6.5% in 16S (Table 1).</p><p>Geographic distribution:  Echinosaura brachycephala  is endemic to Ecuador. It occurs in the west versant of the  Andes in Pichincha and Cotopaxi provinces at elevations between 690 and 1915 m a.s.l. (Fig. 8)  .</p><p>Remarks: Most paratypes (42 specimens) were collected at the type locality (paratopotypes), whereas the remaining eight paratypes are from Tandapi, Pichincha province, Ecuador (Köhler et al., 2004). Although the distributions of  Echinosaura brachycephala and  E. horrida partially overlap,  E. brachycephala seems to be more common above 1200 m a.s.l.</p></div>	https://treatment.plazi.org/id/285E87F7FFA2BC271D92DAF3C5A0FBF4	Public Domain	No known copyright restrictions apply.

Types destroyed or lost (see below), from ‘  Muzo ( Humbo) [Boyacá department, Colombia]’ and ‘ Robledo (near Medellin) [Antioquia department, Colombia]’, exact localities are unknown  .</p><p>Echinosaura horrida palmeri (Boulenger, 1911) – Uzzell, 1965: 85 (for ILS 216–218 from ‘Muzo’ and CNHM 63813 from ‘ 4 km northeast of Bellavista, on the Río Porce, in Antioquia’).</p><p>Designation of neotype: Dunn (1944) described  Echinosaura centralis based on eight specimens, seven of which were collected in Muzo, department of Boyacá, Colombia and deposited in the collection of Museo de La Salle (Bogotá, Colombia, MLS). The remaining specimen was collected in Robledo, M e d e l l í n, d e p a r t m e n t o f A n t i o q u i a, C o l o m b i a and deposited in the collection of Colegio San José (Medellín, Colombia, now Museo de Ciencias Naturales de La Salle, CSJ). However, Dunn did not provide an individual identification for each specimen beyond mentioning that the holotype was the largest specimen from Muzo. According to Uzzell (1965: 85), Hno. Nicéforo María informed him ‘the specimens in the Instituto de La Salle, including the holotype and 6 of the 7 paratypes, have been destroyed’. Details were not given, but those specimens were probably destroyed during the fire of the institute (MLS) in 1948. Therefore, Uzzell based the synonymization of  E. centralis with E. h.  palmeri (currently  E. palmeri) on examination of three topotypic specimens from Muzo [ILS (=MLS) 216–218] and one specimen from ‘ 4 km northeast of Bella Vista, on the Río Porce, in Antioquia’ (CNHM 63813), and according to him near the ‘type-localities’. We visited both Museo de La Salle (Bogotá) and Museo de Ciencias Naturales de La Salle (Medellín), but had no success in locating the remaining type specimen and no record in the museum database suggests its existence. We also noticed that ‘topotypic’ specimens from Muzo municipality mentioned by Uzzell (1965), are actually from Otanche municipality (based on the original specimen tags). Given the absence of type material of  E. centralis, and in accordance with the ICZN (1999) Art. 75, we designate a neotype for this species. We considered this specimen the best candidate because: (1) there is enough evidence to identify it as the same entity described by Dunn (1944), (2) it is an adult male in excellent preservation condition, (3) there is a photograph in life and (4) it could be included in our phylogeny. A description of the neotype is given below.</p><p>Neotype (designated here): MHUA-R 13332, an adult male (Figs 11, 12). Colombia, department of Antioquia, municipality of San Rafael, embalse Jaguas,  Caño Girón (6° 23’ 54.672’ N, 75° 01’ 37.092’ W, 1275 m a.s.l.). Collected on 23 August 2017 by Juan D. Vásquez-Restrepo.</p><p>Description of neotype: Adult male (Figs 11, 12), SVL = 60 mm, TRL = 27 mm, SL = 5.7 mm; HL = 15.2 mm, HW = 9.1 mm, TaL = 10.2 mm. Rostral scale single. Internasals two, longer than wide, with three longitudinal stretch marks, in contact with rostral anteriorly, nasals laterally, frontonasals posteriorly. Nasals subtriangular, in contact with internasals and first supralabials. Frontonasals about three times longer than wide, rectangular, with the posterior edges forming an obtuse angle and a depressed area in the middle part of each scale. Frontal single, wider anteriorly and thinner posteriorly, with a series of longitudinal, barely visible longitudinal ridges. Supraoculars three, first supraocular in contact with frontal and frontonasals, smaller than second and third; third supraocular in contact with three small, keeled ciliaries. Lower eyelid with a palpebral disc divided into three large, unpigmented scales. A large polygonal scale in loreal region not in contact with the supralabials, except on the right side where it is fused with the first large subocular scale. Loreal in contact with preciliary, frontonasal and nasal. Suboculars in four small rows, in contact with a fifth row formed by five large scales on the left side and four on the right side (fifth scale fused with loreal), which are in contact with second to fifth supralabials. Frontoparietals paired, small, well defined. Parietal region covered with small irregular scales. Five upper and four lower labials on both sides. Mental posteriorly in contact with postmental. Postmental trapezoidal, in contact with first infralabial and anterior half of second infralabial. Chin shields large, in one pair, about three times longer than wide, in contact with posterior half of the second and anterior half of the third infralabials, separated from infralabials by three rows of small, hexagonal scales arranged longitudinally, larger than adjacent. Gular region with small, semicircular and tubercular scales, becoming spine-like scales that extend to posterior part of head in dorsal view in four longitudinal rows. Two of these lines are continuous and parallel, extending on paravertebral region and separated from each other by 6–7 irregular, small scales. The remaining two rows extend on upper coastal region, also formed by spine-like scales, but forming a discontinuous longitudinal and sinuous line. On the sides, there is a series of spine-like scales forming oblique lines. Spine-like scales on dorsum separated from each other by small, irregular or tubercular scales. Limbs pentadactyl, digits clawed. Subdigital lamellae on the fourth finger 15/14 (second one on left side divided); subdigital lamellae on the fourth toe 21. Scales on pectoral region flat, rounded, becoming six rows of squared and keeled scales on the belly. Tail with two parallel ridges dorsally, formed by a series of increasing in size scales from the anterior margin of each caudal segment, with more-developed scales forming longitudinal ridges laterally. Tail complete, with three subcaudal scales per caudal segment.</p><p>Dorsum light brown, with some dark-brown scales on head, barely yellowish blotches on body and limbs, and two cream spots at the base of the tail. Scales of ventral surface of head dark brown (almost black), most of them with a cream spot on the centre. Mental and labials with whitish colouration on the posterior edges. Suture between postmental and chin shields with a white transverse stripe. Scales on belly with an irregular pattern of chessboard (black and cream scales). Ventral surface of tail dark brown (almost black) from the basis, except by a few whitish scales on the anterior and posterior part.</p><p>Diagnosis: The following data are based on 70 examined specimens (referred material listed in Supporting Information, Appendix SII).  Echinosaura centralis possesses the following characteristics: (1) snout pointed; (2) internasal divided longitudinally (rarely single); (3) frontonasals paired; (4) frontal single and long (it extends up to the middle of the eyes); (5) frontoparietals paired; (6) supraoculars two or three, large; (7) supralabials 4–6 (usually five); (8) infralabials 3–5 (usually four); (9) postmental single; (10) large chin shields in one pair; (11) two paravertebral ridges, separated from each other by usually five or more small, irregular scales; (12) spine-like scales forming oblique lines on lateral surface of body; (13) ventral scales squared, usually keeled; (14) subdigital lamellae on the fourth finger 12–18; (15) subdigital lamellae on the fourth toe 20–27; (16) femoral pores per hind limb in males 4–9; (17) dorsal surface of tail with two parallel ridges, formed by a series of increasing in size scales from the anterior margin of each caudal segment; lateral surface of tail with more-developed scales forming longitudinal ridges (coded as ‘= pattern’); (18) subcaudals per caudal segment three (when tail is not regenerated); (19) dorsum brown or dark brown, relatively uniform, sometimes with yellowish marks and/or two spots more or less distinguishable at the base of tail; ventral surface of head and neck mainly light brown, except on the anterior part where there is a darker ground colour with some transverse cream blotches, extending to labial scales; ventral surface of body (including limbs) mainly light brown spotted with dark brown or cream, while that of tail almost completely dark. Colouration in preservative is darker in some specimens.</p><p>Combination of these characteristics distinguishes  Echinosaura centralis from its congeners. In addition, the distinctiveness of  E. centralis and its sister-species  E. palmeri (Fig. 2) is corroborated by uncorrected pairwise distances of 17.6% in ND4 and 5.6% in 16S (Table 1).</p><p>Geographic distribution:  Echinosaura centralis  is endemic to Colombia. It occurs in the Cordillera Central from Tolima to  Bolívar departments, the adjacent Magdalena  Valley and the west versant of the  Cordillera Oriental in Cundinamarca and Boyacá departments.  Most records are above 1000 m a.s.l., but its elevation ranges from 50 to 2200 m a.s.l. (Fig. 8)  .</p><p>Natural history: We have observed individuals of  Echinosaura centralis diving into the streams and swimming short distances after being disturbed.</p><p>Variation:  The referred specimens are similar to the neotype with the following noteworthy exception: internasal scale single (an unusual condition) in MHUA-R 10132, 11245, 11440, 12111, 12273 and 13212 .</p></div>	https://treatment.plazi.org/id/285E87F7FFA2BC231E87DC40C4E1FEEA	Public Domain	No known copyright restrictions apply.

Echinosaura keyi possesses the following characteristics: (1) snout relatively short; (2) internasal longitudinally divided; (3) frontonasals paired; (4) frontal extending up to the middle of the eyes, usually single but could be divided transversely; (5) frontoparietals paired; (6) supraoculars three (third supraocular smaller than first and second); (7) supralabials four; (8) infralabials 3–4; (9) tympanum covered with small, granular scales; (10) postmental single, short; (11) large chin shields in one pair; (12) two longitudinal paravertebral ridges formed by spine-like scales, discontinuous on posterior portion of body; (13) series of conical scales of different sizes forming oblique lines on lateral surface of body; (14) ventral scales squared, smooth; (15) femoral pores per hind limb in males usually 8–11; (16) tail with six longitudinal rows of enlarged conical scales on the posterior part of each caudal segment (coded as ‘^ pattern’); (17) subcaudals per caudal segment three (when tail is not regenerated); (18) dorsum dark brown or almost black, with some yellow or cream reticulate spots; ventral surface of head and neck mainly cream with some dark spots; ventral surface of body (including limbs) mainly cream or light brown spotted with dark brown, while that of tail spotted with light and dark brown.</p><p>Combination of these characteristics distinguishes  E. keyi from its congeners. In addition, the distinctiveness of  E. keyi and its congeners is corroborated by a minimal uncorrected pairwise distances of 17.2% in ND4 and 6.7% in 16S (Table 1).</p><p>Geographic distribution:  Echinosaura keyi  is endemic to Ecuador. Its known distribution is restricted to the Pacific versant of north-western Ecuador, including  Santo Domingo, Pichincha, Esmeraldas, Imbabura and Carchi provinces.  Its elevational range is from 200 to 1235 m a.s.l. (Fig. 8)  .</p><p>Remarks:  Echinosaura keyi occurs in sympatry with  E. horrida in the vicinity of Mataje and in El Placer, Esmeraldas province and in La Florida, Pichincha province (Fritts et al., 2002). It is possible that this species extends into southern Colombia.</p></div>	https://treatment.plazi.org/id/285E87F7FFA6BC221E67DC2FC474FB36	Public Domain	No known copyright restrictions apply.

Echinosaura orcesi possesses the following characteristics: (1) snout pointed, long; (2) internasal single; (3) frontonasals paired; (4) frontal long, single; (5) frontoparietals paired; (6) supraoculars large, usually two or three; (7) supralabials 3–5 (usually three); (8) infralabials 2–3 (usually three); (9) postmental single; (10) large chin shields in one pair; (11) dorsally two discontinuous sinuous or S-shaped ridges formed by spine-like scales; (12) alternate tubercular scales on lateral surface of body; (13) ventral scales smooth, squared (or are rounded squares); (14) subdigital lamellae on the fourth finger 20–22; (15) subdigital lamellae on the fourth toe 30–36; (16) femoral pores per hind limb in males usually 9–16; (17) each caudal segment without crests, with a pair of more-developed scales or tubercles on the distal region forming transverse rings (coded as ‘: pattern’); (18) subcaudals per caudal segment five or six (when tail is not regenerated); (19) dorsum brown with transverse alternate darker bands, and with lateral ocelli more or less visible; ventral surface of head and neck cream or clear brown, except on the anterior part where there are some transverse dark brown blotches that extend to labial scales; ventral surface of body (including limbs and tail) mainly cream or reddish light brown spotted with dark (in some cases dark spotted with cream). Colouration in preservative darker.</p><p>Combination of these characteristics distinguishes  E. orcesi from its congeners. In addition, the distinctiveness of  E. orcesi and its congeners is corroborated by a minimal uncorrected pairwise distances of 17.4% in ND4 and 7.4% in 16S (Table 1).</p><p>Geographic distribution:  Echinosaura orcesi  occurs on the western versant of the Cordillera Occidental and in the Pacific region of Colombia, from  Anchicayá region in Valle del Cauca department to north-western Ecuador in Esmeraldas and Carchi provinces.

Holotype: Male (BMNH 1946.8.31.24) (see below) from ‘Noananoá [=Noanamá, Uzzell (1965)], Río San Juan, Choco, S.W. Colombia, 100 feet [~ 30 m a.s.l.]’.</p><p>Echinosaura horrida palmeri (Boulenger, 1911) – Uzzell, 1965: 84.</p><p>Type material: Boulenger (1911) described  Echinosaura palmeri based on a single male deposited in the lizard collection of the British Museum, which he did not designate explicitly as the holotype. However, according to Art. 73.1.2 of the ICZN (1999), this specimen is assumed to be the holotype. Boulenger also did not provide a museum number for it. However, according to the data portal of the BMNH (http://data.nhm. ac.uk), there is a type specimen of  E. palmeri (BMNH 1946.8.31.24) whose information matches the original description. Thus, following the Art. 72.4.1.1 of the ICZN, we consider this specimen as the holotype of  E. palmeri .</p><p>Diagnosis: The following data are based on 70 examined specimens (referred material listed in Supporting Information, Appendix SII).  Echinosaura palmeri possesses the following characteristics: (1) snout pointed; (2) internasal divided longitudinally; (3) frontonasals paired; (4) frontal long, single, extending up to the middle of the eyes; (5) frontoparietals paired; (6) supraoculars usually two or three; (7) supralabials 4–5 (usually five); (8) infralabials 4–5 (usually four); (9) postmental single; (10) large chin shields in one pair; (11) two longitudinal, parallel paravertebral ridges, separated from each other by 3–8 (usually five) small irregular scales; (12) series of spine-like scales forming oblique lines on lateral surface of body; (13) ventral scales squared, usually smooth (rarely weakly keeled); (14) subdigital lamellae on the fourth finger 13–16; (15) subdigital lamellae on the fourth toe 19–25; (16) femoral pores per hind limb in males usually 7–8; (17) each caudal segment usually without crests, with a more-developed scales or tubercles on the distal region forming transverse rings (coded as ‘: pattern’), but in some cases dorsally with some small scales oblique forming a V shape (coded as ‘&lt;pattern’); laterally without more-developed scales forming longitudinal ridges; (18) subcaudals per caudal segment three (when tail is not regenerated); (19) dorsum brown or dark brown relatively uniform, sometimes with yellowish marks and/or two spots more or less distinguishable at the base of the tail; ventral surface of head and neck mainly light brown, except in the anterior part where there are some transverse dark brown blotches that extend to labial scales; ventral surface of body (including limbs) mainly cream or light brown spotted with dark brown, while that of tail almost completely dark. Colouration in preservative could be darker.</p><p>Combination of these characteristics distinguishes  Echinosaura palmeri from its congeners. In addition, the distinctiveness of  E. palmeri and its sister-species,  E. centralis (Fig. 2), is further corroborated by uncorrected pairwise distances of 17.9% in ND4 and 5.6% in 16S (Table 1).</p><p>Geographic distribution:  Echinosaura palmeri occurs in the southern part of Valle del Cauca department in Colombia, through the Pacific and adjacent Cordillera Occidental, to the Darien region in Panama. This is mainly a lowland species (Uzzell, 1965; Köhler et al., 2004), but its range extends from 2 to c. 1520 m a.s.l. (Fig. 8; Jaramillo et al., 2010).</p><p>Remarks:  Echinosaura palmeri occurs in sympatry with  E. orcesi in the Anchicayá region in Colombia, near the southern distribution limit of  E. palmeri and the northern one of  E. orcesi .</p></div>	https://treatment.plazi.org/id/285E87F7FFA7BC211E7ADE18C269FD99	Public Domain	No known copyright restrictions apply.

However, Barbour did not provide museum numbers for the remaining specimens (paratypes according to the Art. 74.4.5 of the ICZN). Later, Uzzell (1965) mentioned the existence only of three paratypes (MCZ 18857–59), but according to the written museum catalogue (available online), there is a fourth specimen (MCZ 18860). Additionally, in the MCZ data portal (http://mczbase.mcz.harvard. edu, accessed July 30 of 2019) this last specimen, also flagged as paratype, was sent to Chicago in 2015. Its current location is unknown. Although the existence of a fourth paratype is not in conflict with the original description (i.e. at least five), we consider as paratypes only those revised by Uzzell (1965), until physical evidence of the existence of MCZ 18860 is given.
