Diagnosis. A small to moderate-sized species (SVL in largest male 50.0 mm, largest female 54.0 mm) of the genus Anolis (sensu Poe 2004)   that differs from all other Mexican and Central American congeners except A. dunni   , A. gadovii   , A. omiltemanus   , and A. peucephilus   by having (1) smooth ventral scales; (2) an oval patch of usually three greatly enlarged supraorbital scales; (3) a pair of greatly enlarged postcloacal scales in males. Anolis liogaster   differs from A. dunni   and A. gadovii   by having 10–15 rows of dorsal scales moderately enlarged (vs. the middorsal scales not or only 2-4 rows slightly enlarged in A. dunni   and A. gadovii   ). It further differs from A. dunni   by having a uniform purple to pink male dewlap (vs. pinkish to orange red male dewlap with semicircular pale streaks and blotches in A. dunni   ). It also differs from A. gadovii   by the absence of a bold reticulated body pattern (vs. such a pattern present in A. gadovii   ). Anolis liogaster   differs from A. omiltemanus   and A. peucephilus   by having longer hind legs with the longest toe of adpressed hind leg reaching to a point between posterior and anterior margin of eye or occasionally to a point between ear opening and eye (vs. to level of ear opening or to a point between shoulder and ear opening in A. omiltemanus   and A. peucephilus   ), usually only a single pair of greatly enlarged sublabial scales in contact with infralabial scales (vs. usually two pairs in A. omiltemanus   and A. peucephilus   ), and a pink to purple male dewlap (vs. orange yellow in A. omiltemanus   and A. peucephilus   ).

Description. Anolis liogaster   is a small to moderate-sized anole (maximum recorded SVL 50.0 mm in males, 54.0 mm in females); dorsal head scales in internasal region weakly keeled, some smooth or rugose, other dorsal head scales smooth or rugose; moderately deep frontal depression present, shallow parietal depression; 5–8 postrostrals; anterior nasal usually single, occasionally divided, the lower scale in contact with rostral and first supralabial or, exceptionally, only with rostral scale; 6–8 internasals; canthal ridge sharply defined; scales comprising supraorbital semicircles well defined, posterior ones smooth, anterior ones weakly keeled, largest scale in semicircles larger than largest supraocular scale; supraorbital semicircles usually broadly in contact, commonly separated by a complete row of scales; 1–3 scales separating supraorbital semicircles and interparietal at narrowest point; interparietal well defined, greatly enlarged relative to adjacent scales, surrounded by scales of small to moderate size, longer than wide, usually larger than ear opening; enlarged supraoculars usually faintly keeled, separated from supraorbital semicircles by a complete row of small scales, or these scales narrowly in contact; 2–5 rows of granular scales between enlarged supraoculars and superciliaries; 2–3 elongate superciliaries, anterior one longest, followed posteriorly by a series of 4–5 rounded or squarish scales of moderate size; usually 3 enlarged canthals, the second canthal largest; 4–9 scales between second canthals; 5–11 scales present between posterior canthals; loreal region slightly concave, 16–39 mostly keeled (some smooth or rugose) loreal scales in a maximum of 4–6 (commonly 4 or 5) horizontal rows; 5–7 supralabials to level below center of eye; suboculars keeled, in broad contact with supralabials (1–3 suboculars in contact with 1–4 supralabials); ear opening vertically oval, oriented slightly obliquely; scales anterior to ear opening granular, about four times as large than those posterior to ear opening; 5–7 infralabials to level below center of eye; 2–5 (usually 4) postmentals, outer pair usually at least four times larger than adjacent median postmental scales; usually one, occasionally zero or two, enlarged sublabials in contact with infralabials on each side; smooth or faintly keeled granular scales present on chin and throat; male dewlap large, extending from level below anterior margin of eye to level of chest; 8–9 horizontal gorgetal-sternal

rows with 7–13 scales per row; modal number of marginal pairs 2–4; female dewlap very small to small; a nuchal crest and a dorsal ridge present in males; scales on middorsum subimbricate, weakly keeled, with rounded posterior margins, grading into smaller granular lateral scales; 10–17 middorsal scale rows slightly to moderately enlarged, two vertebral rows occasionally larger than adjacent rows and usually a few smaller scales interspersed in enlarged rows; lateral scales usually homogeneous, occasionally slightly heterogeneous; 37–58 dorsal scales along vertebral midline between levels of axilla and groin in males, 44–65 in females; 22–36 dorsal scales along vertebral midline contained in one head length in males, 22–34 in females; ventral scales on midsection about twice the size of largest dorsal scales; scales on midventer smooth, subimbricate to imbricate with rounded posterior margins, usually somewhat heterogeneous in size; 35–47 ventral scales along midventral line between levels of axilla and groin in males, 33–45 in females; 24–38 ventral scales contained in one head length in males, 18–28 in females; 102–128 scales around midbody in males, 92–132 in females; tube-like axillary pocket absent; precloacal scales smooth or weakly keeled; males with a pair of greatly enlarged postcloacal scales; tail moderately compressed in cross section, tail height/tail width 1.16–1.50 in males, 1.05–1.59 in females; basal subcaudal scales smooth or faintly keeled, all other caudal scales strongly keeled; lateral caudal scales homogeneous, although an indistinct division in segments is discernible; dorsomedial caudal scale row slightly enlarged, keeled, not forming a crest; scales on anterodorsal surface of brachium and on dorsal surface of antebrachium imbricate, weakly keeled, unicarinate; 20–28 subdigital lamellae on Phalanges II–IV of Toe IV of hind limbs; 6–9 subdigital lamellae on distal phalanx of Toe IV of hind limbs; digital pads dilated, about 3 times the width of distal phalanx. In all specimens examined, the longest toe of the adpressed hind leg reaches to level of tympanum or to a point between shoulder and tympanum. For variation in selected scalation and morphometric characters see Table 12 View TABLE 12 .

The completely everted hemipenis of SMF 96199 View Materials ( Fig. 136 View FIGURE 136 ) is a small, unilobate organ; sulcus spermaticus bordered by well developed sulcal lips and opening into a single apical field void of ornamentation; a low asulcate processus near tip of apex but no asulcate ridge present; no surface ornamentation discernible.

Natural History Notes: In and around the village of Omiltemi, Anolis liogaster   is a common species that can be found on wooden fences, on the lower portions of pine tree trunks, and on the ground.

Geographic Distribution and Conservation. As currently known, Anolis liogaster   is restricted to the hills in the region of Omiltemi in the south-central portion of the Mexican State of Guerrero at elevations between 1995 and 2493 masl ( Fig. 111 View FIGURE 111 ). Given its usual abundance wherever this species occurs, we consider the conservation status of A. liogaster   to be Least Concern based on the IUCN Red List Categories and Criteria ( IUCN 2012).
