These are ZMB 25307A–B, according to Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 167, who (p. 173) designated 25307A lectotype. Type locality: "Deutsch-Ost-Afrika (Amani)", Tanzania. See comment. 

Leptopelis usambarae Ahl, 1929, Sitzungsber. Ges. Naturforsch. Freunde Berlin, 1929: 205. Holotype: ZMB unnumbered, according to the original publication. ZMB 25314 identified as the holotype by Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 175. Type locality: "Usambara", Tanzania; likely the East Usambara Mountains according to  Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 175. Synonymy with Leptopelis uluguruensis by Loveridge, 1957, Bull. Mus. Comp. Zool., 117: 319–20; Schiøtz, 1975, Treefrogs E. Afr.: 46; with Leptopelis grandiceps by Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 165.

Comment

The name Leptopelis barbouri was removed from the synonymy of Leptopelis aubryi by Schiøtz, 1975, Treefrogs E. Afr.: 48, where it had been placed by Loveridge, 1933, Bull. Mus. Comp. Zool., 74: 346, and applied to this species and from that time until 2014 that was the name in general use. In 2014 Gvoždík, Tillack, Menegon, and Loader, 2014, Zootaxa, 3793: 165–187, redescribed the species showed that the type of "Leptopelis barbouri" is actually a member of the species now called Leptopelis flavomaculatus, and that the type of Leptopelis grandiceps (until then considered a synonym of Leptopelis uluguruensis) is of the same species as the old "Leptopelis barbouri", to which they applied the name Leptopelis grandiceps. Schiøtz, 1999, Treefrogs Afr.: 283–284, Channing and Howell, 2006, Amph. E. Afr.: 196–197, and Pickersgill, 2007, Frog Search: 485–487, provided accounts as Leptopelis barbouri. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 289, as Leptopelis barbouri. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 109, reported on comparative tadpole morphology as Leptopelis barbouri.  Harper, Measey, Patrick, Menegon, and Vonesh, 2010, Field Guide Amph. E. Arc Mts. Tanzania and Kenya: 64–65, provided a brief account (as Leptopelis barbouri) for the Eastern Arc Mountains of Tanzania. Penske, Gvoždík, Menegon, Loader, and Müller, 2015, Herpetol. J., 25: 61–64, described the tadpole of a closely related populations (as Leptopelis cf. grandiceps) from the Uluguru Mountains and suggested that it might represent a distinct species. Spawls, Wasonga, and Drewes, 2019, Amph. Kenya: 8, provided a range map for Kenya, photograph, and brief characterization. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 228–229, provided a brief account, photograph, and range map.
