A phylogeny of the species-rich clade of the Neotropical frog genus Leptodactylus sensu stricto is presented on the basis of a total evidence analysis of molecular (mitochondrial and nuclear markers) and non-molecular (adult and larval morphological and behavioral characters) sampled from > 80% of the 75 currently recognized species. Our results support the monophyly of Leptodactylus sensu stricto, with Hydrolaetare placed as its sister group. The reciprocal monophyly of Hydrolaetare and Leptodactylus sensu stricto does not require that we consider Hydrolaetare as either a subgenus or synonym of Leptodactylus sensu lato. We recognize Leptodactylus sensu stricto, Hydrolaetare, Adenomera, and Lithodytes …
High Prevalence Of The Amphibian Chytrid Fungus (Batrachochytrium Dendrobatidis) Across Multiple Taxa And Localities In The Highlands Of Ethiopia, David J. Gower, Thomas M. Doherty-Bone, Roman K.

Surveys of the potentially lethal amphibian chytrid fungus (Batrachochytrium dendrobatidis - Bd) in Africa are patchy, especially in some regions of high species endemicity. We present results of the first Bd surveys of wild amphibians in Ethiopia, for two upland regions on either side of the Rift Valley: the Bale Mountains and the Kaffa region. Surveys were opportunistic so that robust interpretation of the data is limited. Utilizing diagnostic qPCR assays, 51 out of 120 frogs (14 species in 10 genera) tested positive for Bd at altitudes of 1,620–3,225 m, across all genera and species, and all but …
Leptodactylus Pentadactylus, Miriam M. Heyer, W. R. Heyer, Rafael O. De Sá
Leptodactylus Pentadactylus, Miriam M. Heyer, W. R. Heyer, Rafael O. De Sá
Biology Faculty Publications
Adult Leptodactylus pentadactylus (Figure 1) are large, the head is about as wide as long, and the hind limbs are moderately long (Table 1; Heyer and Thompson [2000] provided definitions of adult size and leg length categories for Leptodactylus). Male vocal sacs are not visible externally or are moderately expanded as a single sac. Sexually active males usually do not have hypertrophied forearms (the largest male examined, 195 mm SVL, has very weakly hypertrophied forearms), only the largest males have a single small to moderate size black spine on each thumb. No males have chest spines. Dorsolateral folds are …
Variation, Systematics, And Relationships Of The Leptodactylus BolivianusComplex (Amphibia: Anura: Leptodactylidae), W. R. Heyer, Rafael O. De Sá
Variation, Systematics, And Relationships Of The Leptodactylus BolivianusComplex (Amphibia: Anura: Leptodactylidae), W. R. Heyer, Rafael O. De Sá
Biology Faculty Publications
A cluster of morphologically similar frogs of the genus Leptodactylus having a pair of distinct dorsolateral folds on the dorsum and well-developed lateral fringes on the toes has never been systematically evaluated by examining materials from throughout its geographic range. The species involved are herein referred to as members of the Leptodactylus bolivianus complex. There have been three names proposed for members of this complex: Leptodactylus bolivianus Boulenger, 1898; Leptodactylus insularum Barbour, 1906; and Leptodactylus romani Melin, 1941. The collective range for the L. bolivianus complex is from Costa Rica southward through Panama, extending across northern South America (east of …

Leptodactylus Savagei, W. R. Heyer, Miriam M. Heyer, Rafael O. De Sá
Biology Faculty Publications
Adult Leptodactylus savagei are large, the head is as wide as long or usually wider than long, and the hind limbs are moderate in length (Table 1; Heyer and Thompson (2000) provided definitions of adult size and leg length categories for Leptodactylus). Male vocal sacs are not visible externally. Sexually active males have hypertrophied forearms, usually 1 large black spine on each thumb, rarely with 1 large spine and a prepollical bump, and a pair of black chest spines. A pair of entire dorsolateral folds extend anteriorly from at least one_half to full distance from eye to groin, the …
Hyla Albopunctata, Rafael O. De Sá
Hyla Albopunctata, Rafael O. De Sá
Biology Faculty Publications
Hyla albopunctata is a medium-sized species in the albopunctata group, adults range in size from 42-52 mm SVL (males average 47 mm and females 49 mm). The head is triangular in outline, always longer than wide. The snout is moderately long and acuminate in dorsal view, whereas in lateral view, it is acuminate and protrudes beyond the mandible to form an angle of 45 degrees over the mandible. The canthus rostralis is rounded and distinct, the loreal region is slightly concave, and the internarial region is slightly convex. The eyes are large, approximately twice the diameter of the tympanum. The …
