Arthroleptis schoenebecki Ahl, 1939 "1938", Sitzungsber. Ges. Naturforsch. Freunde Berlin, 1938: 305. Holotype: Not stated, although presumably ZMB; given as ZMB 25289 by Grandison, 1983, Bull. Brit.

Considered a synonym of Arthroleptis adolfifriederici by Loveridge, 1942, Bull. Mus. Comp. Zool., 91: 379; placed in the synonymy of Arthroleptis affinis by Grandison, 1983, Bull. Brit. Mus. (Nat. Hist.), Zool., 45: 77–84.

Abroscaphus affinisLaurent, 1957, Rev. Zool. Bot. Afr., 56: 274–275, by implication.

English Names

Amani Screeching Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 36).

Ahl's Squeaker (Channing and Howell, 2006, Amph. E. Afr.: 50).

Distribution

Mountains of northeastern, eastern, and eastern Tanzania, including North and South Pare, Rubeho, West and East Usambara, Uluguru, Neguu, and Mount Rungwe and Udzungwa mountains, 800 to 2050 m; Taita Hills of Kenya.

Comment

See discussion by Poynton and Loader, 2008, Copeia, 2008: 517–526. Previously in the literature, Arthroleptis affinis was considered a synonym of Arthroleptis adolfifriederici by Loveridge, 1942, Bull. Mus. Comp. Zool., 91: 379, but this synonymy was rejected by Skelton-Bourgeois, 1961, Rev. Zool. Bot. Afr., 63: 324. Discussed by Grandison, 1983, Bull. Brit. Mus. (Nat. Hist.), Zool., 45 who recognized the species. Poynton and Broadley, 1985, Ann. Natal Mus., 26: 539, commented on the distinctiveness of this species from Arthroleptis tanneri. Channing and Howell, 2006, Amph. E. Afr.: 50–51, provided an account and map for East Africa, but implied that the synonymy of Arthroleptis adolfi-friederici leleupi by Poynton, 2003, Afr. J. Herpetol., 52: 108, was premature. Pickersgill, 2007, Frog Search: 302–303, provided an account and suggested that the species is closely related to Arthroleptis tanneri. Frétey, 2008, Alytes, 25: 99–172, summarized the literature. Poynton and Loader, 2008, Copeia, 2008: 517–526, discussed clinal variation among populations. In sum, it appears that the montane populations may warrant species recognition, but the morphological evidence at present may not warrant it. See comments on identifications and range by Loader, Poynton, Lawson, Blackburn, and Menegon, 2011, Fieldiana, Life Earth Sci., 4: 92–93. Harper, Measey, Patrick, Menegon, and Vonesh, 2010, Field Guide Amph. E. Arc Mts. Tanzania and Kenya: 40–41, provided a brief account for the Eastern Arc Mountains of Tanzania.
