Fernando P Ayala-Varela1, Torres-Carvajal Omar.   

Abstract

We describe a new species of Anolis from the southeastern slopes of the Andes of Ecuador, province of Zamora-Chinchipe, Parque Nacional Podocarpus. It belongs to (1) the aequatorialis species-group by being of moderate to large size with narrow toe lamellae, and (2) the eulaemus sub-group by having a typical Anolis digit, in which the distal lamellae of phalanx II distinctly overlap the proximal scales of phalanx I. The new species is most similar morphologically to Anolis fitchi but differs from it mainly by having a dewlap with longitudinal rows of 2-5 granular, minute scales separated by naked skin (longitudinal rows of one or two keeled, large scales separated by naked skin in Anolis fitchi) and a vertically shorter dewlap (longer dewlap in Anolis fitchi).

Introduction

The lizard genus Anolis (anoles) is the most species-rich genus of amniotes, with nearly 400 described forms (Poe 2004; Nicholson 2002). Although the phylogenetic relationships of many Caribbean and Central American species have been analyzed (e.g., Poe 1998, 2004; Creer et al. 2001; Schneider et al. 2001; Jackman et al. 2002; Nicholson 2002), the relationships of South American species formerly called “Dactyloa” (sensu Guyer and Savage 1986; latifrons series sensu Etheridge 1959) are relatively understudied. Accurate estimation of the relationships of this group and the entire Anolis clade requires taxonomic knowledge of South American species, many of which remain undescribed. Here we contribute to this growing body of taxonomic knowledge (e.g., Ayala-Varela 2004; Poe and Yañez-Miranda 2008; Ugueto et al. 2007) with the description of a new species of Anolis from Ecuador. During revisionary work on anoles of Ecuador, we examined some specimens of Anolis similar to Anolis fitchi Williams and Duellman 1984 collected at the Parque Nacional Podocarpus in southeastern Ecuador. We found that the color pattern of these specimens differed dramatically from typical Anolis fitchi. Detailed examination of these specimens revealed other differences in squamation and color pattern indicative of separate species status.

Materials and methods

Specimens examined (Appendix and description below) are housed in the herpetological collections of the Escuela Politécnica Nacional, Quito (EPN), Fundación Herpetológica Gustavo-Orcés, Quito (FHGO), Museum of Comparative Zoology, Harvard University (MCZ), Museo Ecuatoriano de Ciencias Naturales, Quito (MECN) and Museo de Zoología, Pontificia Universidad Católica del Ecuador, Quito (QCAZ). External character terminology follows Williams et al. (1995). Scale counts were made on the left side if applicable. Ten morphological measurements were taken with digital calipers to the nearest 0.1 mm: head length, head width, head height, forelimb length, hindlimb length, snout-vent length (SVL), snout length, ear opening maximum length, interparietal length, and dewlap height. In addition, tail length was measured with a ruler to the nearest 1 mm. Regenerated or broken tails were not measured. Sex was determined by the presence of hemipenes and size of the dewlap. Egg volume was calculated using the formula for the prolate spheroid: V = 4/3 π (length/2) x (width/2)2. Osteological characters were observed in a cleared-and-double stained adult female specimen (QCAZ 6047). All measurements were used in statistical analyses performed in PAST 1.27 (Hammer et al. 2004). Differences in quantitative characters between the new species and Anolis fitchi were evaluated with t-tests. One of the assumptions of the t-test for two samples is that the variances of both samples are equal: therefore, F-tests also were pePageBreakrformed for each character to test for equality of variances. If the variances were not the same (i.e., P < 0.05), an unequal variance t-statistic (Welch test) was used. The distribution map was prepared in ArcMap 9.3 (ESRI, Inc.); WGS84 is the datum for all coordinates presented below.

Diagnosis.

The new species belongs to the punctatus-subsection (Williams 1976a) by having an arrow-shaped interclavicle [T-shaped in the carolinensis-subsection Williams 1976a]. Within the punctatus-subsection, Anolis podocarpus is a member of (1) the latifrons-series sensu Etheridge 1959 by having at least four parasternal chevrons attached to the dorsal ribs, and the lateral processes of the interclavicle divergent from the proximal parts of the clavicles; (2) the aequatorialis species-group (Williams 1976b) by being of moderate to large size (SVL = 73.6−96.0 mm), with narrow toe lamellae; and (3) the eulaemus-subgroup (Williams and Duellman 1984) by having a typical Anolis digit, in which the distal lamellae of phalanx II distinctly overlap the first proximal subdigital scale of phalanx I. The new species lacks transverse processes on most or all of the autotomic caudal vertebrae. Among species in the eulaemus-subgroup (Anolis antioquiae Williams 1985, Anolis eulaemus Boulenger 1908, Anolis fitchi, Anolis gemmosus O’Shaughnessy 1875,Anolis maculigula Williams 1984, Anolis megalopithecus Rueda-Almonacid 1989 and Anolis ventrimaculatus Boulenger 1911), Anolis podocarpus differs from Anolis antioquiae (character states in parentheses) in lacking a canthal ridge projecting above the loreal region (very sharp canthal ridge PageBreakprojecting above the loreal region), and 8−11 supralabials (6−7). Anolis podocarpus can be distinguished from Anolis gemmosus by having a SVL > 70 mm in adults (SVL < 70 mm in Anolis gemmosus), and from Anolis megalopithecus by having 6−9 postmental scales (3−4 in Anolis megalopithecus). From the remaining species in the eulaemus-subgroup (character states in parentheses), Anolis podocarpus differs by the combination of the following characters:PageBreak (1) dewlap moderate in size in females (rudimentary in Anolis eulaemus and Anolis maculigula; absent in Anolis gemmosus and Anolis ventrimaculatus); (2) dewlap skin uniform reddish brown or terracotta, with a dark brown tint anteriorly and orange or pink tint posteriorly in males, Fig. 2 (pale brown in Anolis eulaemus; dark brown, with a pale yellowish brown edge in Anolis fitchi; dull yellowish green, or bluish green proximally shading to yellow or orange distally in Anolis gemmosus; bluish gray proximally, with anterior third pale bluish rose and posterior portion white becoming pale blue towards the belly in Anolis maculigula; red in males and sepia in females in Anolis megalopithecus; dark brown or orange covered by yellow rows of scales and a dark blotch at its base in Anolis ventrimaculatus); (3) dewlap skin uniform dark violet, with a brownish-red tint in females (reddish orange, with black blotches and yellow border in Anolis antioquiae; dark brown in Anolis eulaemus; yellowish green to brown, with dark brown blotches in Anolis fitchi; sepia in Anolis megalopithecus); (4) dewlap with longitudinal rows of 2−5 granular, minute scales separated by naked skin, Fig. 3 (longitudinal rows of one or two keeled, large scales separated by naked skin in Anolis fitchi andAnolis ventrimaculatus); (5) iris bluish turquoise (iris gray or dull bluish gray in males and blue-green in females of Ecuadorian populations; blue in males and pale blue in females of Colombian populations (Williams and Duellman 1984) in Anolis fitchi; dark brown in Anolis maculigula; reddish brown in females in Anolis megalopithecus); (6) 1−3 scales between supraorbital semicircles (4−5 in Anolis antioquiae, and 5−6 in Anolis megalopithecus); (7) interparietal scale present (absent in Anolis antioquiae andAnolis megalopithecus). Among all species in the eulaemus-subgroup Anolis podocarpus is most similar morphologically to Anolis fitchi; in addition to the differences mentioned above, Anolis podocarpus can be distinguished from Anolis fitchi (character states in parentheses, Table 1) by having more scales between second canthals (14–20 and 12–20, respectively; t-test, t = 4.126, P < 0.05); more scales bordering the rostral posteriorly (7–12 and 5–10, respectively; t-test, t = 3.551, P < 0.05); more rows of loreals (9–13 and 6–12, respectively; t-test, t = 7.601, P < 0.05); more postmentals (5–9 and 4–8, respectively; t-test, t = 3.119, P < 0.05); shorter dewlap in males (dewlap height/SVL = 0.10–0.23 and 0.18–0.36, respectively; t-test, t = 4.212, P < 0.05); shorter dewlap in females (dewlap height/SVL = 0.11–0.19 and 0.14–0.23, respectively; t-test, t = 3.165, P < 0.05); and sides of neck with light-blue and pale pink small spots in males (sides of neck with a light yellow irregular stripe, Fig. 1G,H).

Natural history and ecology.

An adult female (SVL 89.1 mm, QCAZ 6045) collected on 1 August 2002 and held in captivity until 27 September 2002 laid an egg (18.5 x 8.4 mm; 682.1 mm3) on 24 August 2002. A juvenile (FHGO 1730) was PageBreakcollected on 25 March 1998 (37.0 mm SVL, 82.5 mm tail length); a larger juvenile (QCAZ 6200) was collected on 1 August 2002 (43.5 mm SVL, 96.0 mm tail length). Specimens of Anolis podocarpus were collected in secondary forest near small streams or in ravines. All individuals were found between 19:00 and 23:00 h sleeping head-up on leaves of ferns, Araceae, Musaceae, on branches 0.30–2.50 m above streams, or on stream shores. This species occurs in sympatry with two undescribed species of anoles at the type locality.

Distribution and conservation.

Anolis podocarpus inhabits the eastern slopes of the eastern Andean cordillera in southern Ecuador, Zamora-Chinchipe province, between 1530−1910 m (Fig. 7). It is known from the upper basin of the Zamora river (Atlantic drainage) in montane cloud forest and low montane evergreen forest (Sierra 1999). Most individuals of this species have been collected within two protected areas in southern Ecuador, Parque Nacional Podocarpus and Refugio de Vida Silvestre El Zarza, which suggests that at least some populations of Anolis podocarpus are well protected. Distribution of Anolis fitchi (triangles) and Anolis podocarpus sp. n. (squares).

Etymology.

The specific epithet podocarpus alludes to the conifer Podocarpus and derives from the Greek words pous, podos (=foot), and karpos (=fruit). The tree Podocarpus gives its name to Parque Nacional Podocarpus, where the new species described in this paper was discovered.
