| Diagnosis | Diagnosis: “Tropidodipsas tricolor sp. nov. is placed in the genus Tropidodipsas based on phylogenetic evidence (Fig. 6). It belongs to the Tropidodipsas fasciata group as defined by Kofron (1987) based on possessing a laterally compressed body, head distinctly wider than neck, protruding eyes of moderate to large diameter, vertebral and paravertebral scales not wider than other dorsal scales, 17 maxillary teeth, 18 dentary teeth, postmental scale absent. The species differs from all described species of Tropidodipsas based on the following combination of characters: (1) 15/15/15 rows of smooth dorsal scales with no enlarged vertebral row; (2) prefrontal broader than long, entering the orbit; (3) loreal square, equally long as high, not entering the orbit; (4) 183 ventral scales in males, 183 in females; (5) 78–79 divided subcaudals in males and 79 in females; (6) 19–22 reddish orange, light-edged bands on body, most with dark brown or black medial stippling, giving the snake a “tricolor” effect; 8 pale bands on tail; (7) ground color black or nearly so; (8) iris chocolate brown; (9) TL/SVL 0.31 in one male specimen, and 0.30 in one female specimen.” (Grünwald et al. 2021: 238) |
