Platycleis tessellata

The calling song consists of a series of quiet diplosyllables, each lasting about 80-200 ms and composed of an opening hemisyllable lasting about 12-50 ms and a closing hemisyllable lasting about 30-130 ms. The syllables are sometimes repeated regularly at the rate of about 6-8/s for long periods of a minute or more (Fig. 325), but at other times they are repeated much less frequently (about 1-4/s) and less regularly (Fig. 326). Sometimes they are grouped into rather loose echemes of very avriable duration. The intervals between syllables vary from about 30-100 ms when they are repeated regularly to about 0.1-1.0 s or more when the repetition rate is irregular. There are no microsyllables. [1]
