A new species in the dicroglossid frog genus is described from Ko Pha-ngan, Ko Samui, and Ko Lanta Yai Islands in southern Thailand. Males of . lack a caruncle on top of the head and very closely resemble (Boulenger, 1887) from Myanmar and western and southern Thailand. However, the new species is distinguished from and its congeners using an integrative taxonomic approach of morphology, mitochondrial DNA, and bioacoustics. . differs from and its congeners by having a unique combination of morphological characters, including body size; skin texture of the interorbital region, dorsum, and shank; toe webbing; relative size of the inner metatarsal tubercle; and coloration of the tympanum, venter, and ova. The advertisement call of the new species is also readily differentiated from that of in temporal parameters. . is highly divergent in mitochondrial DNA from and its congeners, but its phylogenetic position within the genus is not resolved. The natural history of the new species is presented, and the geographic range of in Thailand is clarified.
在泰国南部的阁帕岸岛、阁沙梅岛和阁兰达艾岛发现了叉舌蛙属的一个新物种。该物种的雄性头顶无肉垂,与缅甸以及泰国西部和南部的缅甸短脚角蟾(Boulenger,1887)极为相似。然而,利用形态学、线粒体DNA和生物声学的综合分类方法,可将该新物种与缅甸短脚角蟾及其同属物种区分开来。该新物种与缅甸短脚角蟾及其同属物种的区别在于具有独特的形态特征组合,包括体型大小;眶间区域、背部和小腿的皮肤质地;趾蹼;内跖突的相对大小;以及鼓膜、腹部和卵的颜色。新物种的求偶鸣叫在时间参数上也很容易与缅甸短脚角蟾的区分开来。该新物种的线粒体DNA与缅甸短脚角蟾及其同属物种高度不同,但在该属中的系统发育位置尚未确定。本文介绍了新物种的自然史,并明确了其在泰国的地理分布范围。
