Diagnosis. A small species (our Species B of the Anolis quercorum   complex, see above; SVL in largest male 46.0 mm, largest female 41.0 mm) of the genus Anolis (sensu Poe 2004)   that differs from all Mexican and Central American anoles except A. quercorum   and a species described below (our Species C of the A. quercorum   complex) by having a combination of (1) strongly keeled ventral scales; (2) usually a patch of three greatly enlarged supraocular scales; (3) 10–12 rows of slightly to moderately enlarged dorsal scales that are smaller than ventral scales; (4) short hind legs, longest toe of adpressed hind leg usually reaching to ear opening or to a point between ear opening and eye, ratio shank length/SVL 0.23–0.25; (5) circumnasal usually in contact with first supralabial; and (6) a large pink dewlap in males and a very small red or pink dewlap in females. Anolis carlliebi   differs from A. quercorum   and the species described below (our Species C of the A. quercorum   complex) in the ranges and average values of several morphometric and pholidotic characters (see Table 9 View TABLE 9 ), most obvious in (1) number of middorsal scales in one head length; and (2) ratio shank length/HL. Also, Anolis carlliebi   differs from A. quercorum   and the species described below (our Species C of the A. quercorum   complex) in hemipenis morphology (hemipenis unilobed in A. carlliebi   vs. slightly to distinctly bilobed in the other two species) and by substantial genetic distances (see above).

Coloration in life was recorded as follows: Dorsal ground color Drab (19); dorsal surface of head Clay Color (18); with Raw Umber (23) interorbital bar and Cream Color (12) lines from eyes to neck; vertebral region Light Buff (2) with Mars Brown (25) chevrons; dorsal surface of limbs and tail Antique Brown (24); ventral surface of body, limbs and tail Pale Horn Color (11) with Pale Pinkish Buff (3) speckles; dewlap Spectrum Orange (9) with Pale Buff (1) gorgetals; iris Cinnamon-Rufous (31).

Coloration after four months preservation in 70% ethanol was recorded as follows: Dorsal surfaces of head and body Medium Neutral Gray (298) with large confluent Dusky Brown (285) blotches on middorsum and with a Grayish Horn Color (268) postocular stripe, edged with Burnt Umber (48); limb Medium Neutral Gray (298) suffused with Dusky Brown (285); tail Drab (19) with faint Hair Brown (277) vertical bands; ventral surfaces of head, body, limbs, and tail Pale Buff (1) with a suffusion of Medium Neutral Gray (298) on venter; finger and toe pads Vandyke Brown (282).

Variation. The paratypes agree well with the holotype in general appearance, morphometrics, and scalation ( Table 9 View TABLE 9 ). They differ in some scalation characters as follows: The number of slightly to moderately enlarged dorsal scale rows varies from 14 to 20. All specimens have a single elongate prenasal. Suboculars in contact with supralabials (2–4 suboculars in contact with 1–4 supralabials) in all specimens examined. All males have a pair of greatly enlarged postcloacal scales.

The coloration in life of an adult female paratype from Ixtlán de Juárez (GK-4502, IBH) was recorded as follows: Dorsal ground color Drab (19) with Drab-Gray (256) vertebral line, Olive Brown (278) dots and a Light Buff (2) lateral line; dorsal surface of head Verona Brown (37) with Brussels Brown (33) interorbital bar; dorsal surface of limbs Cinnamon-Rufous (31) with Yellow Ocher (14) bars; dorsal surface of tail Drab (19) with suffusion of Robin Rufous (29); ventral surface of body, limbs and tail Light Buff (2) with Pale Pinkish Buff (3) suffusions; dewlap Orange Yellow (8) grading into Burnt Orange (19) towards front and Pale Buff (1) gorgetals; iris Natal Brown (49).

The completely everted hemipenis of UTA-R 52816 ( Fig. 57 View FIGURE 57 ) is a small unilobate organ; sulcus spermaticus bordered by weakly developed sulcal lips and opening into a single apical field; no asulcate processus present; no surface ornamentation discernable.

Etymology. The name carlliebi   is a patronym honoring Carl S. Lieb who has contributed substantially to our knowledge of Mexican anoles.

Natural History Notes. The two SMF type specimens of Anolis carlliebi   were collected during a 4.5 hours night search in a pine oak forest at the campus of the Ixtlán University. The specimens were found sleeping on twigs between 0.3 and 1.0 m above the ground. Most of the following is summarized from the information provided in Ramirez-Bautista et al. (2002a,b). The habitat of Anolis carlliebi   includes xerophilic brush land, thorn forest, and deciduous tropical forest, heavily altered in most of the species’ range by human activities. During daytime, this lizard is mostly found on the leaf litter covered floor, but also on rocks and low vegetation. It is also found in disturbed areas, dump-yards, and along house fences, and is easy to spot at night sleeping on shrub twigs. It feeds on small beetles ( Coleoptera   , family Curculionidae   ), true bugs (Homoptera, family Cicadellidae   ), and Hymenoptera   (families Ichneumonidae   and Braconidae   ) ( Canseco-Márquez & Gutiérrrez-Mayén 2010). The limited available data suggest seasonal reproduction in A. carlliebi ( Ramirez-Bautista et al. 2002b)   . Canseco- Márquez & Gutiérrrez-Mayén (2010) noted that one female collected in May in Santiago Dominguillo laid an egg and that a male collected in October in San Lucas Teteletitlán had enlarged testicles. Ramirez-Bautista et al. (2002a) reported a male courting a female on a Prosopis   tree in September. Canseco-Márquez & Gutiérrrez-Mayén (2010) reported observations of juveniles in November in Santa María Texcatitlán.

Geographic Distribution and Conservation. As currently known, Anolis carlliebi   is restricted to the Tehuacán-Cuicatlán Valley and the adjacent Ixtlán Valley in the northern central portion of the Mexican State of Oaxaca at elevations of 650 to 2,515 masl ( Fig. 71 View FIGURE 71 ). Given its usual abundance wherever this species occurs, it seems justified to classify A. carlliebi   as Least Concern based on the IUCN Red List Categories and Criteria ( IUCN 2012).
