Description

Adult males measure about {{convert|50|mm|in|1|abbr=on}} (based on the sole male in the type series) and adult females {{convert|40|-|68|mm|in|1|abbr=on}} in snout–vent length. The head is slightly wider than it is long. The snout is bluntly rounded in dorsal view and truncate in profile. The tympanum is brown. The finger discs are much wider than the digits; the toe discs are noticeably smaller that those on the fingers. The fingers have no webbing whereas the toes are about one-third webbed. The dorsum is green or brown, typically with dark brown longitudinal paravertebral markings and/or dark flecks. A pale dorsolateral stripe is present, and a pale supra-cloacal stripe is often present. The flanks are brown or green, and the groin is blue with black spots. The ventrum is pale creamy gray with dark flecks.^[2]

Habitat and conservation

This species is only known from two localities. It was reported as relatively common at the type locality, but recent surveys have failed to locate it. Even though the type locality is entirely within the Munchique National Park, cultivation of illegal crops is causing habitat loss; spraying these crops with glyphosate may have impacted this species. The second population in Vereda Santa Elena was discovered in 2005, but an intensive survey in 2016 recovered only one individual. In this locality, Gastrotheca trachyceps is threatened by the establishment of eucalyptus plantations and the use of pesticides on these plantations.^[1]
