Type locality. Philippines. Luzon: Laguna, Los Baños, Mount Makiling , base, secondary forest on campus .

Distribution. Philippines: Laguna: Mt. Makiling and Los Baños; Quezon: Mt. Banahaw (new record).

Diagnosis. This species differs from L. sanchezi by its whitish face, a fastigium that is not orange apically, without clear longitudinal bands in the vertex (Robillard et al., 2013), and male genitalia with long and rounded pseudepiphallic lophi and C-shaped pseudepiphallic parameres.

Calling song. The song of L. puyos consists of long trills (duration = 3.1± 0.8 s [1.7– 4.0 s]; period = 25.6± 2.8 s [22.4– 33.1 s]) made up of more than 200 syllables of increasing intensity ( Figs. 7 A–C). Syllable duration = 12.6±1.2 ms (10–15 ms). The spectrogram analysis reveals that the frequency spectrum is completely ultrasonic. The syllables show a clear dominant peak at 23.12±1.06 kHz typically corresponding to the first peak of a harmonic series with an intermediary peak at ca. 25 to 30 kHz ( Figs. 7D, 7E ).

Habitat. The species is found in secondary habitats in the type locality, i.e., foot of Mt. Makiling; specimens were found in leaf litter and on top of leaves of small plants ( Fig. 6A ).
