The representative tadpole of Glyphoglossus (39.2 mm total length; 11.6 mm body length, 27.6 mm tail length, stage 33; Fig. 2C) is characterized by a globose body with a peritoneum colored silver by a uniform layer of iridophores, a depressed snout, and a long, pointed tail that is black during the day and night on the posterior twothirds. In preservative, the reflectance of the iridophores is lost, but the melanic pigment on the tail remains. The wide, transparent spiracle at mid-abdomen (Fig. 2F) has a broad, bi-lobed ventral wall.
