We describe a new species of the Scinax ruber clade from Northeastern Brazil that occurs in widely separated geographic areas in the Atlantic Forest of southern Bahia state and the Highland Humid Forest of Serra de Baturité, northeast Ceará state. Scinax tropicalia sp. nov. (holotype coordinates: -14.795694°, -39.172645°) is diagnosed from all 75 currently recognize species of the S. ruber clade by bioacoustical and morphological adult traits, such as duration (0.11-0.31 s) and dominant frequency (1.59-1.85 kHz) of the advertisement call, snout shape rounded, nearly rounded, or semi-circular in dorsal view and rounded to slightly protruding in profile, bilobate vocal sac, absence of pectoral glands and spicule-shaped papillary epidermal projections on nuptial pads, and color pattern on the dorsum of body and hidden surfaces of hindlimbs.
我们描述了一种来自巴西东北部的红腹树蛙分支新物种，它分布在巴伊亚州南部大西洋森林和塞阿拉州东北部巴图里蒂山高地湿润森林中相距甚远的地理区域。热带红腹树蛙新物种（正模标本坐标：南纬14.795694°，西经39.172645°）通过生物声学和成年形态特征与目前红腹树蛙分支的所有75个已知物种相区分，这些特征包括求偶鸣叫的持续时间（0.11 - 0.31秒）和主频（1.59 - 1.85千赫兹）、吻部形状在背面观为圆形、近圆形或半圆形，侧面观为圆形至稍突出、双叶状声囊、无胸腺以及婚垫上无针状乳头状表皮突起，还有身体背部和后肢隐藏面的颜色图案。
