We present the first observations on the breeding of Glyphoglossus, and although ovipositional dips probably occur in all microhylids that oviposit eggs as surface films, these images apparently are the first video sequences of this behavior for the family. Microhylids are among those frogs that are difficult to observe calling and breeding, and these observations were obviously made on one of those unusual occasions where nothing was going to disturbthem. Some hylids make ovipositional dips similar to those described here, but the females of other hylids and some ranids (e.g., part of the Lithobates catesbeianus group; Aronson 1943a–b)
