A new species of Narrow-mouthed frog of the genus Kaloula is described from northern Peninsular Malaysia. Kaloula latidisca sp. nov. is genetically and morphologically most similar to K. baleata and K. indochinensis but differs from those and other congeners by the unique combination of the following characters: (1) adult males SVL 49.2-56.2 mm (x̅=53.5 ± 3.0; N=4); (2) finger tips expanded into large, transversely expanded discs (disc width 2.8-3.1 mm, x̅=3.0 ± 0.1); (3) inner metatarsal tubercle large, oval, distinctly raised, slightly shorter than first toe; (4) three subarticular tubercles on fourth toe; (5) toe webbing formula: I 1-2 II 1-3 III 2-3.5 IV 4-2 V; and (6) yellow to orange irregularly shaped patch on the axillary, inguinal and posterior region of thigh.
一种新的姬蛙属狭口蛙物种在马来西亚半岛北部被描述。宽盘姬蛙（Kaloula latidisca sp. nov.）在基因和形态上与巴氏姬蛙（K. baleata）和中南半岛姬蛙（K. indochinensis）最为相似，但与它们及其他同属物种的区别在于具有以下独特的特征组合：（1）成年雄性体长49.2 - 56.2毫米（平均值x̅ = 53.5 ± 3.0；样本数量N = 4）；（2）指尖扩展成大的横向扩展圆盘（圆盘宽度2.8 - 3.1毫米，平均值x̅ = 3.0 ± 0.1）；（3）内侧跖突大，椭圆形，明显隆起，略短于第一趾；（4）第四趾有三个亚关节瘤；（5）趾间蹼式：I 1 - 2 II 1 - 3 III 2 - 3.5 IV 4 - 2 V；以及（6）在腋窝、腹股沟和大腿后部区域有黄色至橙色的不规则形状斑块。
