Scinax muriciensis Cruz, Nunes & Lima, 2011
|Species Description: Cruz CAG, Nunes I, De Lima MG 2011 A new Scinax Wagler belonging to the S. catharinae clade (Anura: Hylidae) from the state of Alagoas, northeastern Brazil. Zootaxa 3096: 18-26.|
They share the most physical characteristics with S. strigilatus, and both members of the S. catharinae group. Although they are both brown to camouflage in their arboreal habitat, they differ in that S. muriciensis has large granules on the forearm, a more pointed snout in the profile, and round finger discs while S. strigilatus has small granules on the forearm, a lower snout profile, and elliptical finger discs (Cruz et al. 2011).
In life, S. muriciensis have a general pale brown-colored pattern on their dorsum with darker coloration around their midbody arranged in stripes that become spots at the mid-body and sacral region. They have a W-shaped mark between their eyes and a darker pigmented canthus rostralis. There is a white spot in the axilla and green flash marks in the inguinal and hidden regions of the thighs and shanks. The dorsal surface of the limbs and feet are stripped. The hands are spotted with brown. The ventrum is white with dark brown spots that may merge into marbling on the gular and limbs. From the ventral view, you barely see this striped pattern on the limbs. In preservative, the colors fade but the patterning remains the same (Cruz et al. 2011).
The male specimens generally had consistent morphology, except the snout varied in how much it protruded. Additionally, the amount of spotting or marbling on the ventrum varies (Cruz et al. 2011).

Distribution and Habitat
Country distribution from AmphibiaWeb's database: Brazil
Life History, Abundance, Activity, and Special Behaviors
Tadpoles can be found in forest streams (Cruz et al. 2011).
Females of S. muriciensis are likely ovoviviparous, laying eggs that hatch into tadpoles, similar to S. strigilatus. As these species are found near running water and streams, it is likely that their eggs are laid close to or in the water (Camurugi et al. 2013).
Adult S. muriciensis are found in sympatry with adult Aplastodiscus sibilatus, Chiasmocleis sp., Crossodactylus dantei, Hypsiboas semilineatus, H. freicanecae, and Ischnocnema aff. ramagi (Cruz et al. 2011).
Larval S. muriciensis can be found with larval Agalychnis granulosa, Aplastodiscus sibilatus, Crossodactylus dantei, Hypsiboas freicanecae, and Proceratophrys renalis (Cruz et al. 2011).

General habitat alteration and loss
PHYLOGENETIC RELATIONSHIPS:Scinax muriciensis was placed in the S. catharinae species group based on morphology (Cruz et al. 2011).
The genus name, “Scinax”, comes from the Greek word “skinos”, which means “quick or nimble” (Duellman et al. 2016).
The species epithet, “muriciensis” is a reference to the place it was found, the Municipality of Murici in the State of Alagoas of Northeastern Brazil (Cruz et al. 2011).
Scinax muriciensis also has the suggested name of Ololygon muriciensis (Duellman et al. 2016)

Members of the S. catharinae complex are distributed in well preserved environments and S. murciensis is in the northernmost geographic area of this clade (Cruz et al. 2011).
