Captive management and reproductive biology of Orlov's Treefrog, Rhacophorus orlovi Ziegler & Köhler, 2001 (Amphibia: Anura: Rhacophoridae), including larval description, colour pattern variation and advertisement call

In this paper, the successful keeping and breeding of Orlov's Treefrog, Rhacophorus orlovi Ziegler & Köhler, 2001, is described for the first time. Breeding took place at low temperatures of 19° to 24° C, based on two couples from northern Vietnam. The species turned out to have a noticeably rapid development. Slightly more than two weeks after foam nest building, larvae developed hindlimbs, and after about four weeks, all larvae were metamorphosed, with a snout-vent length of about 10.5 mm. In addition, we provide for the first time the morphological description of the larva of R. orlovi, and we describe so far unknown subadult and adult colour patterns and the advertisement call of this species from Vietnam.
