Phyllonastes heyeri, originally described as Phrynopus heyeri (Lynch, 1986), is a diminutive frog from Peru and Ecuador with many morphological features in common with Adelophryne adiastola (Lynch, 1986). De la Riva and Köhler (1998; Journal of Herpetology 32:328-329) suggested that the Phrynopus peruvianus group is likely paraphyletic with respect to Phyllonastes. Adults males are small, 12.9-14.1 mm SVL, females 13.1-15.9 SVL. Very low warts are present o nthe skin of the dorsum and appears to be pitted or “dimpled.” Skin of venter pitted. In preservative, dorsum is pale reddish-brown with brown interorbital bar, scapular and sacral chevrons, and suprainguinal spots; anal patch is brown; posterior surfaces of thighs cream speckled with brown; faint bars on shanks; brown on side of head – continuing as dark brown band onto flanks. Forelimbs partially banded. Head is narrower than body, slightly wider than long; tip of snout extends farther anteriorly than anterior edge of upper jaw. Loreal region slopes abruptly to lips; supratympanic fold thick, glandular, and not prominent. The tympanum is concealed partially or entirely beneath the skin, separated from eye by distance equal to 66% tympanum length. No vomerine odontophores or teeth. Forearm lacks ulnar tubercles; one palmar tubercle present and is larger than over thenar tubercle. Supernumerary palmar tubercles present at the bases of fingers II-IV. No discs or fringes on fingers. Two metatarsal tubercles, both prominent and subconical, inner slightly larger and slightly longer than wide; toes lack lateral fringes and webbing.
