JULIAN VELASCO,2 KENNETH MIYATA,3;4 AND ERNEST E. WILLIAMS?-4 ABsTRACT. We describe two northern South American Pacific lowland species of Anolis that historically have been associated with names that are currently nomina nuda. Anolis lyra new species is similar to Anolis vittigerus but differs primarily in possessing smaller dorsal scales on the head and body and in color pattern. Anolis anchicayae new species is similar to Anolis peraccae and Anolis fasciatus but differs primarily in size and color pattern. We scored the new species for skeletal and external morphological phylogenetic characters and performed a parsimony analysis with 251 additional Anolis species using molecular and morphological data. Anolis anchicayae is sister to A. peraccae in a basal group of South American “alpha” Anolis (“dactyloids,” “‘/atifrons” group). Anolis lyra is placed with other lemurinus-group Anolis within the large clade of mainland “beta” Anolis (“Norops’’). Key worps: Anolis anchicayae; Anolis lyra; Colombia; Ecuador RESUMEN. Describimos dos especies de Anolis de zonas bajas del Pacifico de Colombia y Ecuador que tradicionalmente han estado asociadas con nombres en nomen nundum. Anolis lyra sp. nov. es parecido a Anolis vittigerus pero se diferencia principalmente en que presenta las escamas del dorso de la cabeza y el cuerpo mas pequefias, y en el patron de coloracion. Anolis anchicayae sp. nov. es parecido a Anolis peraccae y Anolis fasciatus pero se diferencia principalmente en el tamafio y el patron de coloracion. Se codificaron caracteres filogenéticos de morfologia externa y osteologia y se realizo un analisis de parsimonia con 251 especies adicionales de Anolis usando una combinacion de datos morfoldgicos y moleculares. Anolis anchicayae es taxon hermano de A. peraccae dentro de un grupo basal de especies suramericanas de Anolis “alfa.” Anolis lyra esta relacionado con otras especies del grupo lemurinus dentro de un clado mas grande compuesto por especies continentales de Anolis “beta.” ‘Department of Biology and Museum of Southwestern Biology, University of New Mexico, Albuquerque, New Mexico 87131, U.S.A.; e-mail: anolis@unm.edu * Grupo de Ecologia Animal, Departamento de Biologia, Universidad del Valle, A.

Poe was able to diagnose each species and identify MCZ specimens on the basis of Williams’ unpublished notes, which clearly were influenced by Miyata’s work on the second species described herein. Additionally, Williams is responsible for Figure 6. Subsequent to submission of this manuscript, the editor provided Poe with a chapter of Miyata’s Ph.D. thesis, never published, describing the second of the two species described herein. Poe incorporated information from this manuscript into the diagnosis of this species. © The President and Fellows of Harvard College 2009. i) Ernest Williams and collaborators pub- lished a series of papers from 1983 to 1992 describing “‘new or problematic” Anolis from Colombia. These papers reviewed and ex- panded the Colombian anoline fauna and established the country as a center of diversity for the Anolis clade. The publica- tion of these descriptions and other taxo- nomic works on Colombian lizards (e.g., Ayala and Castro, 1983) prompted the need for a summary of available information. Stephen Ayala (1986) obliged and produced a list of the 205 lizard species thought to occur in Colombia. This list included eight species of Anolis (and species in other clades) listed in quotes (“”) and associated with authors to signal that descriptions were not yet published but were forthcoming. Pub- lished descriptions of Anolis species associated with four of these names soon followed (A. danieli Williams 1988, A. ruizi Rueda and Williams 1986, A. lamari Williams 1992, A. medemi Ayala and Williams 1988), but the other names have languished without descrip- tions as nomina nuda for over 20 years. The aim of this paper is to rectify this situation with respect to two of the remaining names well known to Colombian herpetologists. MATERIALS AND METHODS We consider species to be evolutionary lineages (Simpson, 1961; Wiley, 1978) and operationalize this concept by identifying species on the basis of consistent differences between populations. That is, we hypothesize that populations that are diagnosable by major differences in the frequencies of traits are distinct evolutionary lineages or species (see Wiens and Servedio, 2000). Measurements were made with digital calipers on preserved specimens and are given in millimeters (mm), usually to the nearest 0.1 mm. Snout-vent length (SVL) was measured from the tip of the snout to BREVIORA No. 516 the anterior of the cloaca. Head length was measured from the tip of the snout to the anterior edge of the ear. Femoral length was measured from the midline of the venter to the knee, with the limb bent at a 90-degree angle. Head width was measured at the broadest part of the head, between the posterolateral corners of the orbits. Com- parisons were made with preserved material of the putative closest relatives of the new species, and with published species descrip- tions, preserved material, or both of more distant relatives (online Appendix 1). Scale terminology and characters used mainly follow standards established by Williams (e.g., Williams et al, 1996) for species descriptions of anoline lizards. Skeletal description is given in terms of Poe’s (1998, 2004) and Etheridge’s (1959) characters. See those papers for more detailed descriptions of skeletal conditions and alternative condi- tions in Anolis. We scored the new species for the mor- phological phylogenetic characters of Poe (2004; Appendix 1) and performed a parsi- mony analysis of these taxa and 251 other species of Anolis and eight outgroups with the use of 1,291 parsimony-informative characters from published sources and some of our additional unpublished morphological data. This dataset includes 91 morphological characters (Poe, 2004), 998 sites of mtDNA (NADH_ dehydrogenase subunit 2, five transfer RNAs; Nicholson et al., 2005), and 182 sites of nuclear DNA (internal tran- scribed tracer region; Nicholson, 2002). Codes for morphological data for A. anchi- cayae and A. lyra are in online Table |. We used PAUP* version 4.0b10 (Swofford, 2002) to perform a heuristic search with 100 random additions of taxa and tree- bisection-reconnection branch swapping. We also used PAUPrat (Sikes and Lewis, 2001) to perform several runs of the parsi- mony ratchet (Nixon, 1999) to find optimal 2009 Figure 1. Anolis anchicayae new species, male.

Anolis lyra differs from all other South American Anolis except A. vittigerus in possessing a small red dewlap with a dark central spot in males and a lyre-shaped symbol in the occipital region (Fig. 8). Anolis lyra differs from A. vittigerus in possessing smaller middorsal scales (mean number of longitudinal scales in 5% SVL for A. lyra = 8.5, A. vittigerus = 5.8; P = 0.006, Mann- Whitney U test), more scales between supra- orbital semicircles (mean = 2.3 in A. Lyra, 0.6 in A. vittigerus; P = 0.001, Mann-Whitney U test), and more scales between interparietal and supraorbital semicircles (¥ = 4.1 in A. lyra, 2.4 in A. vittigerus; P = 0.001, Mann- Whitney U test; Fig. 10). Also, A. Lyra tends to display much weaker lateral striping (..e., broken lines only extending to the axillae versus broad stripes to groin in A. vittigerus) and a more prominent lyre-shaped posterior head marking (Fig. 8; absent to weak in A. vittigerus).

NEW SOUTH AMERICAN ANOLIS 13 lyra were collected sleeping at night in secondary humid forest on twigs or leaves 1-5 m high. Some specimens were collected by day in lower parts of trees and on ground. Etymology. This species is named for the lyre-shaped marking on the back of its head (Fig. 8). DISCUSSION Relationships. Many taxa are scored for as few as 3% of parsimony informative charac- ters (1.e., only external morphological data). Inclusion of such poorly scored taxa will tend to increase the number of most parsi- monious trees and thus lower support levels such as bootstrap frequencies (Huelsenbeck, 1991). We nevertheless include these taxa to achieve an estimate of their phylogeny relative to A. anchicayae and A. lyra and to increase the accuracy of phylogenetic place- ment of A. anchicayae and A. lyra (Gauthier et al., 1988; Hendy and Penny, 1989). Because support values are uniformly low and many optimal trees resulted, as expected, we summarize results with a majority-rule consensus of optimal trees. Results of the phylogenetic analysis of A. anchicayae and A. lyra are shown in Fig. 11. Anolis anchicayae is sister species to A. peraccae among an unresolved group of South American alpha Anolis (approximate- ly equivalent to Etheridge’s [1959] Jatifrons series and Guyer and Savage’s [1986] ““Dac- tyloa’). The “‘latifrons” group usually has been found to be monophyletic (including **Phenacosaurus’’; Etheridge, 1959; Jackman et al., 1999; Poe, 2004, fig. 2; Nicholson et al., 2005) but is occasionally paraphyletic (Poe, 2004, fig. 5; this study) in recent studies. Obviously, more phylogenetic work is needed on the South American alpha Anolis. Anolis lyra is grouped with some other lemurinus-group species A. bicaorum and A. 14 BREVIORA No. 516 B fortunensis A trachyderma other Anolis tolimensis aeneus medemi roquet maculiventris richardi granuliceps 67 bonairensis poecilopus 67, extremus tropidogaster riseus lionotus rinitatus oxylophus luciae macrolepis esperanzai : concolor wiliamsmittermeierorum 92 pinchoti Weel ial limifrons roboscis Zeus Inderenae 92 g2 92;— bicaorum nicefori lyra <—_ solitarius femurinus. rulzi if galpenten ant aequatorialis ocelloscapularis cadildae ee humilis a 71 fitchi . notopholis fraseri compressicauda 74 jacare magnaphallus microtus pachypus insignis 92 tropidolepis squamulatus capito frenatus cuprinus latifrons tropidonotus ventrimaculatus 92 cobanensis apollinaris parvicirculatus agassizi polylepis chioris cupreus festae 92 dollfusianus punctatus altae USCOeNSIS kemptoni uilae townsendi transyersalis Moreuthes anchicayae <—=— 92 anton peraccae isthmicus iasciatle microlepidotus sericeus Boe tigeri intermedius outgroups laeviventris pentaprion vociferans 92 ortoni : megapholidotus utilensis subocularis nebuloides quercorum nebulosus crassulus sminthus liogaster dunni adovi aylori viltigerus we Webel 92 aquaticus 92 biporcatus petersi 92 gracilipes uniformis 92 bitectus _. polyrhachis loveridgei_ . purpurgularis 92 nitens chrysolepis nitens scypheus meridionalis auratus annectens onca | barkeri lineatus Figure 11. Relationships of (A) Anolis anchicayae and (B) A. lyra based on parsimony analysis of 1,271 informative characters and 253 species of Anolis and eight outgroups. Shown are two portions of the majority-rule consensus of 4,961 maximum parsimony trees (i.e., this is not a bootstrap tree). Relationships present in less than 100% of optimal trees are identified with percentages above those clades or with clade collapsed if present in less than 50% of optimal trees. All taxa are Anolis. Figure 9A shows relationships of basal alpha Anolis (“latifrons” group sensu lato, ““dactyloids”); Fig. 9B shows relationships of mainland beta Anolis (mainland “Norops’’). Other analyzed species are omitted for brevity. 2009 lemurinus within the mainland beta Anolis (Etheridge, 1959; = “Norops’’). Anolis lyra shares several /emurinus-group characters with these species (e.g., narrow toepads, a dark interorbital bar, lack of enlarged post- cloacal scales, dorsal color pattern; see Kohler, 1999). The Jemurinus group of Anolis might be nonmonophyletic (Nicholson, 2002). In the current estimate, this group is composed of three putative clades: A. /emur- inus, A. bicaorum, and A. lyra; the large- hemipenes group, A. tropidolepis, A. pachy- pus, and A. magnaphallus; and A. vittigerus. Anolis vittigerus is superficially similar to A. lyra but displays an unusual combination of characters, including, for example, nasal overlap of the premaxilla. Future studies will examine whether these unusual condi- tions signal independent evolution or some less interesting phenomenon such as limited sample size. Remarks. With the description of these two species, the remaining nomen nudum Anolis from Ayala (1986) are A. “‘jericoen- sis,’ “A. malkini,’ and A. “urraoi.” We have examined specimens of putative A. “‘jericoen- sis’ and are unable to distinguish these from A. eulaemus. We are unable to distinguish preserved specimens of putative “A. malkini” from A. pentaprion. Specimens of putative A. “urraoi’ are likely to represent a distinct species similar to A. fuscoauratus and A. maculiventris. Anolis fuscoauratus clearly is composed of multiple undescribed species (authors’ personal observations); thus, de- scription of A. “urraoi’ could be challenging.
