Allobates subfolionidificans is a vulnerable and endemic leaf-litter frog from the state of Acre, Brazilian Amazonia. We monitored a population of A. subfolionidificans through regular censuses and mark-recapture of 181 individuals during an entire breeding season to characterize its reproductive behavior. The space use of A. subfolionidificans individuals differed between sexes, with males using smaller and more segregated spaces. Males defended territories and were aggressive against same-sex individuals, which was not the case in females. The daily cycle of calling activity showed peaks in the morning and in the afternoon, and the occurrence of reproductive events was positively correlated with monthly rainfall. The breeding behavior comprised vocal and tactile interactions, although the species lacked reproductive amplexus. Egg and larvae attendance, as well as tadpole transport to water environments was performed mostly by males but occasionally by females, probably in cases of desertion by the father. This species is characterized by performing courtship, mating, oviposition, as well as egg and larvae attendance exclusively on the under surface of leaves, a unique behavior among members of the superfamily Dendrobatoidea.
亚叶生蟾（Allobates subfolionidificans）是一种来自巴西亚马孙州阿克里的易危特有枯叶蛙。我们在整个繁殖季节通过定期普查和对181只个体进行标记重捕，对亚叶生蟾的一个种群进行了监测，以描述其繁殖行为。亚叶生蟾个体的空间利用存在性别差异，雄性使用的空间更小且更隔离。雄性保卫领地并对同性个体具有攻击性，而雌性则不然。鸣叫活动的日周期在上午和下午出现高峰，繁殖事件的发生与月降雨量呈正相关。繁殖行为包括声音和触觉互动，尽管该物种缺乏抱对行为。卵和幼体的照料以及蝌蚪向水环境的转移主要由雄性完成，但偶尔也由雌性完成，可能是在父亲遗弃的情况下。该物种的特点是求偶、交配、产卵以及卵和幼体的照料都仅在叶片下表面进行，这在树蟾超科成员中是一种独特的行为。
