Megophrys Kuhl and Van Hasselt are an Asian radiation of terrestrial frogs which are usually associated with montane forest (Mahony et al. 2017). The Annam horned frog (Megophrys intermedia) is reported from montane evergreen forest in Vietnam and Lao People's Democratic Republic (Stuart 2005; Hendrix et al. 2008; Nguyen et al. 2009; Tran 2013; Orlov et al. 2015; IUCN 2017; Mahony et al. 2017). The IUCN Red List assessment for the species reports an elevational range of 782-1500 m asl (IUCN 2017) although the type locality was reported to be above 1500 m asl (Smith 1921), and Tran (2013) collected a specimen at 1515 m asl. Megophrys intermedia is assessed as Least Concern (IUCN 2017) and little is known about the reproductive behaviour and life history of the species. In Lam Dong Province (Vietnam), male M. intermedia call in March (Tran 2013); on the Langbian Plateau (Vietnam), male specimens are reported to call by day and by night from March to May and specimens called from within deep crevices between boulders in streams (Smith 1921); in Xe Kong Province (Laos), males call or guard egg clutches that are laid in water in July (Stuart 2005).
角蟾属(Megophrys)的库氏角蟾(Megophrys Kuhl)和范氏角蟾(Megophrys Van Hasselt)是亚洲的一类陆栖蛙类,通常与山地森林有关(马奥尼等人,2017年)。安南角蟾(Megophrys intermedia)在越南和老挝人民民主共和国的山地常绿森林中有记录(斯图尔特,2005年;亨德里克斯等人,2008年;阮等人,2009年;陈,2013年;奥尔洛夫等人,2015年;世界自然保护联盟,2017年;马奥尼等人,2017年)。世界自然保护联盟对该物种的红色名录评估报告其海拔分布范围为海拔782 - 1500米(世界自然保护联盟,2017年),尽管其模式产地据报道高于海拔1500米(史密斯,1921年),并且陈(2013年)在海拔1515米处采集到了一个标本。安南角蟾被评估为无危(世界自然保护联盟,2017年),人们对该物种的繁殖行为和生活史知之甚少。在越南林同省,雄性安南角蟾在3月鸣叫(陈,2013年);在越南朗边高原,据报道雄性标本在3月至5月白天和夜晚都会鸣叫,并且标本是在溪流中巨石间的深裂缝内鸣叫(史密斯,1921年);在老挝色贡省,雄性在7月鸣叫或守护产在水中的卵块(斯图尔特,2005年)。
