Sigalegalephrŋnus minangkabauensis sp. nov. Holotype. — Museum Zoologicum Bogoriense Amphibian Collection, MZB 25738 (field number ENS 16028), an adult male (Fig. 7) from Gunung Kunyit, Kecamatan Panyabungan Selatan, Kabupaten Kerinci, Provinsi Jambi, Indonesia, 2.26013°S, 101.49512°E at 1402 m, collected by E. Wostl, E.N. Smith, W. Trilaksono, and G. Barraza on 24 June 2013. Diagnosis and comparison. —The following combination of characters is unique to Sigalegalephrŋnus minangkabauensis: (1) A small (19.32 mm SVL) and slender toad without parotoid glands. (2) Fingertips I and II are rounded and not expanded. (3) Fingertips III and IV are rounded and expanded. (4) The toe tips are rounded but not expanded. (5) The webbing is rudimentary in the hands and moderate in the feet. (6) The dorsum is light greenish-brown with a middorsal pinstripe extending from the tip of the snout to the vent. (7) The flanks have a single stroke of dark brown extending from the posterior end of the orbit to the inguinal region. (8) The dorsal surface is moderately tuberculate. (9) The ventral surface is smooth with scattered black spots. Sigalegalephrŋnus minangkabauensis can be distinguished from S. mandailinguensis (characters in parentheses) based on the following differences. The tympanum is barely discernible (tympanum distinct). The finger-pads are moderately defined (finger-pads prominent). The fingertips are rounded but not expanded (distinctly spatulate on tips III to IV). The hands lack subarticular tubercles (distinct subarticular tubercles under Fingers III and IV). The webbing of the foot is more extensive, extending to the last phalanx on Toes I and II (last phalanx free of webbing). The pads on toes are moderately defined (pads prominent). The feet lack subarticular tubercles (distinct subarticular tubercles under Toes IV and V). The overall texture is glossy with fewer tubercles on the dorsum and flanks (overall texture rugose, body and flanks extensively tuberculate). Taking into account the uncorrected genetic distance between the two species of Sigalegalephrŋnus (Table 2), the aforementioned comparisons provide adequate diagnostic characters to warrant S. minangkabauensis as a species distinct from S. mandailinguensis.
