Leptopelis signifer Ahl, 1929, Sitzungsber. Ges. Naturforsch. Freunde Berlin, 1929: 216. Syntypes: ZMB (3 specimens) unnumbered, according to the original publication; one of these, MCZ 17530 (on exchange from ZMB) is likely a paratype, not a syntype (see Barbour and Loveridge, 1946, Bull. Mus. Comp. Zool., 96: 141); ZMB 11773A designated lectotype by Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 181. Type locality: "Derema", Tanzania, this rendered as "'Derema', East Usambara Mountains, Tanzania, approx. 5.05°S 38.66°E" by Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 181. De Witte, 1941, Explor. Parc Natl. Albert, Miss. G.F. de Witte (1933–1935), 33: 102, reported the syntypes ("cotypes") as being from "Urwald zwischen Beni und Mboga". Synonymy by Loveridge, 1933, Bull. Mus. Comp. Zool., 74: 346, and Schiøtz, 1975, Treefrogs E. Afr.: 39. Formerly considered a junior synonym of Leptopelis christyi by Laurent, 1972, Explor.
