Description

Platymantis corrugatus (Duméril, 1853)

Fig. 4 B

Vernacular name.

Corrugated Tagomukhus Forest Frog

Material examined.

Philippines • 3 individuals; Mindanao, Agusan del Sur Province, Municipality of San Francisco, Barangay Caimpugan; 08°24'12"N, 125°53'49"E; KU 314062–64 • 10 individuals; same locality data as for preceding; 08°24'13"N, 125°52'37"E; MBS 1967 –68, 1974–76, 1989–93 • 2 individuals; Municipality of Talacogon, Barangay Zillovia; 08°25'25"N, 125°45'26"E; MBS 1742, 1752.

Identification.

A gray, tan, or brown dorsum interspersed with irregular longitudinal folds; most individuals possess distinct dark “ face masks ” with dark pigmentation from the nares, through the loreal region, the pre- and post-ocular region, to the tympanic region (Taylor 1920 a; Inger 1954).

Remarks.

Individuals of this crepuscular species were heard actively calling, hiding underneath leaf litter on the forest floor in the Katigbok and Caimpugan peat swamp forests of Agusan Marsh. It occurs throughout the Philippine archipelago except in Palawan and Sulu PAICs (Diesmos et al. 2015). Populations in the Mindanao faunal region often possess a less darkly pigmented lateral head surface (Alcala and Brown 1998, 1999; Brown et al. 2012 b; Diesmos et al. 2015; Cobb 2016).
