Amphibians
Mertensophryne anotis (Boulenger, 1907)
EOL Text
A close phylogenetic relationship between Bufo taitanus, S. anotis, and Mertensophryne micranotis has been proposed due to the characteristic crown seen on the tadpoles of these three species (Muller 2005).

Stephopaedes anotis is a small forest dwelling frog of about 45mm in SVL (Channing 1993). The skin has smooth warts. The head is equally long as it is broad. The pointed snout projects beyond the mouth. The interorbital space is flat and broader than the upper eyelid (Boulenger 1907). It does not possess a tympanum or columella (Channing 1993). Vocal sacs are not present in males. Paratoid glands are large and extend to the base of the arm on the sides. Fingers and toes are short, with the toes one-third webbed. The webs are covered with granules. It has two subconical, round metatarsal tubercles. The fingers and the fourth toe have double subarticular tubercles (Boulenger 1907).
Diagnosis: S. anotis can be differentiated from Wernia preussi by its presence of warts and distinct parotoid glands. It is distinguished from B. taitanus by a strongly pointed snout, less oblique lores and larger paratoid glands (Boulenger 1907).
Coloration: The dorsum and sides of the head are blackish or light colored with blackish cross-bars (Boulenger 1907). The venter is yellow and speckled with black (Boulenger 1907; Channing 1978).
Tadpole Morphology: As a tadpole, it is known to have a unique crown on the top of its head (Cannatella 1986). This crown possibly acts as an accessory respiratory surface (Channing 1993). The crown is a ring of expanded epithelial tissue around the eyes and nostrils. In comparison to other Bufo tadpoles, Stephopaedes anotis has no mental gap in its oral papillae (Channing 1978).

This species is only known from two threat-defined locations: the Chirinda Forest in eastern Zimbabwe (where it occurs at approximately 900-1,300 m asl) and the Dombe Forest in adjacent Mozambique (where it occurs around 150 m asl). Based on these two threat-defined locations, its extent of occurrence (EOO) is 1,354 km.

S. anotis is found in Zimbabwe, in the Chirinda Forest at elevations around 900-1300 m above sea level. It is also found in Mozambique in the Dombe Forest. It is not found outside of forests (Stuart et al. 2008).

Adults tend to camouflage with the leaf litter (Channing 1993).Eggs can be found in pockets of water between the buttress roots of Chrysophyllum gorungosanum trees, or in water filled trunks of fallen trees (Stuart et al. 2008).
