Pleurodema guayapae Barrio 1964

Diagnosis A stout, rather small frog, almost indistinguishable from the sibling species Pleurodema nebulosum, bur having a quite shorter, sharply truncate snout, shorter legs and tympanum concealed, interorbital distance Å? of the upper eyelid breadth; fringes in sides of toes moderate.

Known from central Argentina surrounding the Salinas de Ambargasta (Córdoba, La Rioja, San Juan, Catamarca, and Santiago del Estero Provinces) and from southern Bolivia, in the Department of Santa Cruz (at 200m asl).

Adult morphology Snout-vent of about 40-45 mm. Head wide, with very short snout, sharply truncate; nose strongly protruding on the lower jaw. Nostrils swelling, opening anteriorly. Interocular distance larger than the internarial interval and narrower than the upper eyelid. Canthus rostralis indistinct; loreal region vertical. Maxillary teeth weak: no vomerine teeth present. Eyes prominent, laterally located. Tongue moderately wide, oval, free behind. Tympanum concealed; dermal supratympanic fold faint; glands at the mouth joint present. Fingers slightly fringed; rate of the finger lengths: II-IV-I-III. Metacarpal and subarticular tubercles as in Pleurodema nebulosum. Toes slightly webbed at the base and fringed; metatarsal tubercles as in Pleurodema nebulosum. No tarsal fold evident. When hindleg is adpressed, heel reaches the axial. When the femurs are bent at right angles to body, the tibio-tarsal articulations fail to meet. Smooth folded skin on the dorsum, longitudinally scattered with scanty flat warts; ventrally smooth; lower surface of thigh coarsely granular. No lumbar glands; nuptial pads brownish, inconspicuous; gular skin folded in males. Coloration: Dorsally grayish, scantily spotted. Belly white.
