Abstract
Phylogenetic analyses using mtDNA gene sequences revealed the presence of two genetic clades in the genus Leptobrachella (former Leptolalax) from northern Thailand. One formed a clade including L. ventripunctata and L. aerea, while another included L. bourrreti and L. laoi. The first clade contained L. cf. minima from Doi Suthep, while the second clade contained L. murphyi and two undescribed species, one from Doi Inthanon, at a high altitude of 2,300 m asl, and another from Mae Hong Son, at Myanmar border. These form a clade, that is sister to L. murphyi. Morphologically, the first species is generally similar to L. murphyi, while the second species resembles L. cf. minima. However, they are clearly distinguished from those described species by great genetic differences, and we describe them as L. korifi sp. nov. and L. sinorensis sp. nov., respectively.

Leptobrachella korifi sp. nov.
Diagnosis: A small-sized form of the genus Leptobrachella; adult female 22.7 mm in SVL (n=1); ventral side dusty; tibiotarsal articulation reaching anterior corner of eye; pectoral gland very large; lateral fringe on toes weak.
Etymology: The specific epithet, korifi, is from the Greek “koreefee,” meaning summit, in reference to the high elevation of the habitat [Doi Inthanon, Chiang Mai Province] of the new species.

Leptobrachella sinorensis sp. nov.
Diagnosis: A medium-sized form, adult males 26.6–27.1 mm in SVL (n=3); tibiotarsal articulation reaching center of eye; pectoral gland indistinct; ventral side of head and body creamy white.
Etymology: The specific epithet, sinorensis, is from the Greek “seenoro,” meaning border, in reference to the type locality [Mae Hong Son Province], which lies near the Myanmar border of Thailand.
