| Diagnosis | Diagnosis: Homonota taragui is a small species of Homonota (SVL= 41.86 mm; Table 1) that can be distinguished from other species of the genus by the following set of characters: a well-marked dorsal, reticulate, dark pattern contrasting with the lighter colored background; small, star-shaped chromatophores on the abdomen; presence of an internasal scale contacting the rostral scales; granular scales covering the post-orbital region of the head; granular scales forming smooth edges of the meatus auditory; presence of moderately keeled scales on the dorsal and lateral surface of the body; keeled scales contiguously disposed on the dorsal surface of the body; cycloid scales covering the dorsal surface of the arms; moderately keeled scales interspersed with cycloid scales covering the dorsal and anterior regions of the thighs. Homonota taragui differs from H. andicola in the following characters: presence of keeled scales on the dorsal and lateral surface of the body and dorsal surface of the thighs (keeled scales absent in H. andicola); the auditory meatus with smooth edges formed by granular scales (serrated edges formed by conical scales in H. andicola). Homonota taragui differs from H. borellii in the following characters: presence of keeled scales on the lateral surface of the body and dorsal surface of the thighs (keeled scales absent in H. borellii, Fig. 4); presence of an internasal scale contacting the rostral scales (internasal scales absent in H. borellii, Fig 5). Homonota taragui differs from H. darwinii in the following characters: keeled scales extended along the whole dorsal body surface (keeled scales only on the posterior half of the dorsal body surface in H. darwinii); presence of keeled scales on the lateral surface of the body and dorsal surface of the thighs (keeled scales absent in H. darwinii); subcaudal scales transversely rectangular (vertically rhomboid in H. darwinii, Fig 6); the auditory meatus with smooth edges formed by granular scales (serrated edges formed by conical scales in H. darwinii). Homonota taragui differs from H. fasciata in the following characters: rows of keeled scales on dorsal surface of the body composed by moderately keeled scales disposed contiguously (composed by strongly keeled scales separated from each other in H. fasciata); dorsal surface of the arms covered by cycloid scales (covered by keeled scales in H. fasciata); presence of an internasal scale contacting the rostral scales (internasal scale absent in H. fasciata, Fig. 5); subcaudal scales transversely rectangular (rhomboid vertically and transversely rounded in H. fasciata, Fig. 6); the auditory meatus with smooth edges formed by granular scales (serrated edges formed by conical scales in H. fasciata). Homonota taragui differs from H. rupicola in the following characters: presence of keeled scales on the lateral surface of the body and dorsal surface thighs (keeled scales absent in H. rupicola, Fig. 4); presence of an internasal scale contacting the rostral scales (internasal scale absent in H. rupicola, Fig. 5). Homonota taragui differs from H. underwoodi in the following characters: presence of chromatophores on the abdomen (chromatophores on abdomen absent in H. underwoodi); presence of keeled scales on the dorsal and lateral surface of the body and dorsal surface of the thighs (keeled scales absent in H. underwoodi); presence of an internasal scale contacting the rostral scales (internasal scales absent in H. underwoodi, Fig. 5); subcaudal scales transversely rectangular (vertically rhomboid in H. underwoodi); the auditory meatus with smooth edges formed by granular scales (serrated edges formed by conical scales in H. underwoodi). Homonota taragui differs from H. uruguayensis in the following characters: rows of moderately keeled juxtaposed scales on the dorsal surface of the body (strongly keeled imbricate scales in H. uruguayensis); dorsal surface of the arms covered by cycloid scales (covered by keeled scales in H. uruguayensis); the post-orbital region of the head covered only with granular scales (covered with granular scales interspersed with large keeled scales in H. uruguayensis, Fig. 7). Homonota taragui differs from H. whitii in the following characters: presence of keeled scales on the dorsal and lateral surface of the body and dorsal surface of the thighs (keeled scales absent in H. whitii); presence of an internasal scale contacting the rostral scales (internasal scale absent in H. whitii, Fig. 5); subcaudal scales transversely rectangular (rounded and longitudinally elongated in H. whitii, Fig. 6); the auditory meatus with smooth edges formed by granular scales (serrated edges formed by conical scales in H. whitii). Homonota taragui differs from H. williamsii in the following characters: presence of keeled scales on the lateral surface of the body and dorsal surface of the thighs (keeled scales absent in H. williamsii); subcaudal scales transversely rectangular (longitudinally elongated in H. williamsii, Fig. 6); the auditory meatus with smooth edges formed by granular scales (serrated edges formed by conical scales in H. williamsii). |

| Etymology | Named after the word for “lizard” in the language of the South American Guarani culture, which inhabited the area currently corresponding to Corrientes Province. (Vázquez de Espinosa, 1948; Sorg, 2007), Although the workd means lizard, current inhabitants use it to refer to the territory of the province. |
