| Diagnosis | Diagnosis. Anolis riparius sp. nov. and A. aquaticus are the only semiaquatic Middle American anoles that have a large orange-red dewlap with yellow in males (Fig. 6B). Anolis riparius sp. nov. differs from A. aquaticus in possessing smaller dorsal scales of the head and body (e.g., 15–19 scales across the snout between the second canthals in A. riparius sp. nov. versus 7–14 in A. aquaticus, Fig. 5B), and is phylogenetically distinct (see below). Anolis riparius sp. nov. is distinguished from the other Middle American semiaquatic anoles as follows: from A. robinsoni sp. nov. by male dewlap color (chocolate brown with ill-defined brick red horizontal stripes in A. robinsoni sp. nov.); from A. lionotus and A. poecilopus by male dewlap color (solid yellow-orange in A. lionotus and A. poecilopus), lack of postcloacal scales in males (usually present in A. lionotus and A. poecilopus), and possession of zero to three enlarged rows of middorsal scales (a broadband of 10–24 enlarged middorsal scale rows in A. poecilopus and A. lionotus); from A. barkeri by smaller size (maximum SVL 73 mm in A. riparius sp. nov., 91 mm in A. barkeri), presence of distinctly expanded toe pads (ratio width of expanded pads / width of distal phalanx 1.8–2.2 in A. riparius sp. nov. versus 1.4–1.6 in A. barkeri), and presence of a single row of middorsal caudal scales (double row in A. barkeri).
