“…Interestingly, with the exception of the proboscis and a red dewlap, D. phyllorhina differs from D. punctata by only a few quantitative morphological traits. The identification of females, which lack both the proboscis and a developed dewlap, is indeed difficult (Rodrigues et al, 2002).…”

“…The typical orange dewlap of D. punctata has been described as nearly invariable throughout this species' distribution (Avila-Pires, 1995;Rodrigues, 1988;Williams, 1982). However, at least one population in southern Brazilian Amazonia presents white dewlaps (Rodrigues et al, 2002). Because there are no records of D. punctata and D. philopunctata occurring in sympatry and females of the two species cannot be distinguished based on their extremely reduced dewlaps, the validity of D. philopunctata has been questioned (Avila-Pires, 1995).…”

“…Based on morphological characters, it has been consistently grouped with taxa in the heteroderma species group (Castañeda and de Queiroz, 2013;Nicholson et al, 2012;Poe, 2004;Poe et al, 2012). By contrast, morphological examinations suggested D. phyllorhina as related to the punctata group (Rodrigues et al, 2002;Yánez-Muñoz et al, 2010). If D. phyllorhina is in fact more closely related to D. punctata than to the remaining proboscis-bearing species, anole rostral appendages have evolved at least twice.…”

We redescribe the enigmatic lizard Anolis proboscis based on new material collected on the Distrito Metropolitano de Quito, province of Pichincha, Ecuador. We describe the first females reported for the species, increasing the diagnosis to include sexually dimorphic data; and present new information on characters previously undescribed, such as the cranial helmet and hemipenial morphology. We propose that the nasal appendage is not a homologous apomorphic character among A. proboscis and A. phyllorhinus, thus the A. laevis species-group is not a valid clade. In fact, we suggest that A. proboscis is closely related to species previously classified as "Phenacosaurus"; while A. phyllorhinus is part of the A. punctatus species-group. We provide new information on the distribution and natural history of A. proboscis; suggesting that it should be classified under the IUCN category and criteria of "Endangered EN B1ab(i,ii,ii)+2ab(i,ii,iii)". We propose A. proboscis as an emblematic species of the Distrito Metropolitano de Quito, in particular for the conservation of Las Tolas and Lloa-Mindo regions.Keywords.

ResumenRedescribimos a la enigmática lagartija Anolis proboscis basados en nuevo material colectado en el Distrito Metropolitano de Quito, provincia de Pichincha, Ecuador. Describimos las primeras hembras conocidas de la especie, ampliando así la diagnosis con datos sobre dimorfismo sexual; y presentamos nueva información sobre caracteres antes no descritos, como el casco craneal y la morfología de los hemipenes. Proponemos que el apéndice nasal no es un carácter homólogo apomórfico entre A. proboscis y A. phyllorhinus, por lo que el grupo-de-especies A. laevis no es un clado válido. De hecho, sugerimos que A. proboscis está cercanamente relacionado con especies previamente clasificadas como Phenacosaurus; mientras que A. phyllorhinus es parte del grupo-de-especies A. punctatus. Aportamos nueva información sobre la distribución e historia natural de A. proboscis y sugerimos que sea clasificado bajo la categoría y criterios de riesgo de extinción de la IUCN de "En Peligro EN B1ab(i,ii,ii)+2ab(i,ii,iii)". Proponemos que A. proboscis sea considerado una especie de reptil emblemática del Distrito Metropolitano de Quito, en especial para la conservación de la zonas de Las Tolas y LloaŰMindo.

Phenotypic variation among populations, as seen in the signaling traits of many species, provides an opportunity to test whether similar factors generate shared phenotypic patterns in different parts of a species’ range. We investigate whether genetic divergence, abiotic gradients, and sympatry with closely related species explain variation in the dewlap colors of slender anoles, Anolis fuscoauratus. To this aim, we characterized dewlap diversity in the field, inferred population genetic structure and evolutionary relationships, assessed whether dewlap morphs are associated with climate and landscape variables, and tested for non-random associations in the distribution of A. fuscoauratus morphs and sympatric Anolis species. We found that dewlap colors vary among but not within sites in A. fuscoauratus. Regional genetic clusters included multiple morphs, while populations with similar dewlaps were often distantly related. Morphs did not segregate in environmental space, suggesting that dewlaps are not locally adapted to abiotic factors. Instead, we found a negative association between certain morphs and Anolis species with similar relative dewlap brightness, suggesting that interactions with closely related species promoted dewlap divergence among A. fuscoauratus populations. Slender anoles emerge as a promising system to address questions about parallel trait evolution and the contribution of signaling traits to speciation.
