|Diagnosis||Diagnosis: “We assign Anolis poei both to the aequatorialis series, based on moderate to large body size, narrow toe lamellae, small head scales, smooth ventral scales, and uniform dorsal scalation; and to the eulaemus-subgroup, based on a typical Anolis digit, in which the distal la- mellae of phalanx III distinctly overlap the first proximal subdigital scale of phalanx II (Williams 1976; Williams and Duellman 1984; Castañeda and de Queiroz 2013).|
At present ten species are recognized within the eulaemus-subgroup: Anolis anoriensis Velasco et al. 2010, A. antioquiae Williams 1985, A. eulaemus Boulenger 1908, A. fitchi Williams & Duellman 1984, A. gemmosus O’Shaughnessy 1875, A. maculigula Williams 1984, A. megalopithecus Rueda-Almonacid 1989, A. otongae Ayala-Varela & Velasco 2010, A. podocarpus Ayala- Varela & Torres-Carvajal 2010, and A. ventrimaculatus Boulenger 1911. Anolis poei differs from them mostly in dewlap features. The dewlap in males of A. poei has a yellowish-green (or both yellow and green) gorgetal region, light blue border, and white sternal and marginal regions (Fig. 3). It has a blackish gorgetal region, and creamy white sternal region with light brown scales in A. anoriensis; brown gorgetal region, and pale brown marginal region in A. eulaemus; bluish-gray gorgetal region, orange stripes, pale bluish-rose anterior third, and white sternal region becoming pale blue toward the belly in A. maculigula; sepia background, with red narrow and irregular stripes on each side of rows in A. megalophitecus; white, pale yellow, or greenish-yellow gorgetal region, with white or pale-yellow marginal and sternal regions in A. otongae (Fig. 3); dull yellowish-green or light blue gorgetal region, shading to dull cream, greenish yellow or orange on the marginal region, with white or bluish green gorgetal rows with or without brown spots and with yellowish white, yellow or orange sternal region in A. gemmosus (Fig. 3). The dewlap in males of A. poei has wide rows of 3−7 scales separated by naked skin; the width of these rows is one scale in A. fitchi, 2−5 granular, minute scales in A. podocarpus, 1–2 scales in A. ventri- maculatus, 3−6 scales in A. otongae, and 2−3 scales in A. gemmosus. In addition, females of the new species lack a dewlap, which is present in females of A. anoriensis, A. antioquiae, A. eulaemus, A. fitchi, and A. podocarpus.
Anolis poei is most similar morphologically to A. otongae and A. gemmosus (Fig. 4). From the former species (character states in parenthesis) A. poei differs in having small dorsal chevrons in females (large dorsal chevrons extending onto flanks), pale yellowish-brown iris (iris dark blue), interparietal scale (if present) surrounded by small swollen scales (interparietal scale surrounded by relatively enlarged flat scales), enlarged postanal scales separated by 3−5 scales (postanal scales separated by 1−2 scales), and in lacking a dark stripe on side of head (dark coppery-brown stripe present). Ad- ditionally, PCA analyses suggested that specimens of A. poei have shorter jaws, as well as lower and narrower heads than A. otongae (Table 2, Fig. 5), with PC1 (39% of total variation) represented mainly by head height, head width, and jaw length.
The new species can be distinguished from A. gemmosus (Table 3) in having fewer scales between second canthals (11−14, mean = 12.08 and 12−21, mean = 15.25, respectively; t = 5.31, P<0.005); fewer scales between supraorbital semicircles (1−3, mean = 1.62 and 1−5, mean = 3.13, respectively; t = 4.46, P<0.005); more lamellae under phalanges III-IV of fourth toe (18−19, mean = 18.92 and 14−18, mean = 17.33, respectively; t = -7.86, P<0.005); a narrower head (head width = 7.84−8.84, mean = 8.29 and 6.97−17.41, mean = 10.82, respectively; t = -7.03, P<0.005); lower head (head height = 6.54−7.48, mean = 6.92 and 5.42−15.96, mean = 9.51, respectively; t = -6.96, P<0.005); and shorter snout (snout length = 6.75−7.30, mean = 6.92 and 5.79−14.95, mean = 10.58, respectively; t = -11.74, P<0.005).

|Etymology||The specific name is a noun in the genitive case and is a patronym for Steve Poe, who has published important contributions to the systematics and evolution of Ano- lis lizards (Poe 2004, 2011). During his collecting trips to Ecuador in 2009 and 2010, Poe trained several young herpetologists in field collecting techniques and inspired them to explore the diversity of anole lizards. This paper is one of the products resulting from that inspiration. [from AYALA-VARELA et al. 2014]|
