Comment

Nyctixalus margaritifer considered possibly a synonym of Philautus aurifasciatus by Liem, 1973 "1971", Philipp. J. Sci., 100: 157. See discussion by Dubois, 1981, Monit. Zool. Ital., N.S., Suppl., 15: 255-257, about confusion surrounding the application of the name Nyctixalus margaritifer. Iskandar, 1998, Amph. Java Bali: 84-85, provided a brief account and restriction of the name to the Javan population. See comments under Nyctixalus flavosignatus and Nyctixalus pictus. Dubois, 1981, Monit. Zool. Ital., N.S., Suppl., 15: 257, removed Ixalus flavosignatus from synonymy under Nyctixalus margaritifer; without discussion, implying that two species in this genus occur in Java. Iskandar, 1998, Amph. Java Bali: 84-85, did not recognize Nyctixalus flavosignatus as distinct from Nyctixalus margaritifer but did not address the issue. See identification table by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 122-123, to compare this species to other rhacophorids of the Sunda Shelf region. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 516.
