For nearly four decades, harlequin toads, genus Atelopus, have suffered unparalleled population declines. While this also results in limited understanding of alphataxonomic relationships, these toads face an urgent need for advances in systematics to inform conservation efforts. However, high intraspecific variation and cryptic diversity have hinde...

... that show a length of 7 ± 2 ms (3-4 ms) each. Pulses slightly increase in length over the course of each call and are not modulated in frequency. Tadpole: Duellman & Lynch (1969) described a single gastromyzophorous tadpole from Río Puyo in Provincia Pastaza, Ecuador, under the name A. spumarius spumarius. We assign their specimen (KU 121385; Fig. 5) to A. colomai sp. n., based on the resemblance of living tadpoles (Fig. 6) reared from topotypic adults of A. colomai sp. n. under laboratory conditions and based on being the only harlequin toad known from the general area. Our examination of the tadpole in Stage 37 corroborates most characters given by Duellman & Lynch (1969). ...

... with black and golden dots; pupil black surrounded by cupreous to golden ring; towards metamorphosis, the pattern and coloration remain stable with a decrease of golden markings at late stages; limbs turn orange in Stage 42 (Fig. 6). In preservative, the single specimen used for the tadpole description by Duellman & Lynch (1969) is entirely faded (Fig. ...

Flying squirrels are nocturnal, gliding relatives of tree and ground squirrels (order Sci-uridae). Despite 49 species existing, literature on Asiatic flying squirrels is scarce, thus they are overlooked in conservation action plans. Recently, three species of giant flying squirrel (Aeromys tephromelas, Petaurista petaurista and Aeromys thomasi) wer...
