Arthroleptis adolfifriederici Nieden, 1911

Class: Amphibia > Order: Anura > Family: Arthroleptidae > Subfamily: Arthroleptinae > Genus: Arthroleptis > Species: Arthroleptis adolfifriederici

Arthroleptis adolfi-friederici Nieden, 1911 "1910", Sitzungsber. Ges. Naturforsch. Freunde Berlin, 1910: 440. Syntypes: ZMB 21787 and 21789 (total of 2 specimens) according to Laurent, 1985, in Frost (ed.), Amph. Species World: 14. ZMB 21789 is now FMNH 73836 according to Blackburn, Gonwouo, Ernst, and Rödel, 2009, Breviora, 515: 11. Type localities: "Rugegewald" and "Bugoiewald", Rwanda. According to Blackburn, Gonwouo, Ernst, and Rödel, 2009, Breviora, 515: 11–12, Rugege is currently name Nyungwe and Bugoie may currently be Bugoya, both ca. 1800–2400 m elevation.

Comment

Grandison, 1983, Bull. Brit. Mus. (Nat. Hist.), Zool., 45 discussed this and other large-sized species. See Poynton and Broadley, 1985, Ann. Natal Mus., 26: 538–539. See Lawson, 1993, Herpetol. Nat. Hist., 1: 34, for Cameroon record. Perret IN IUCN, Conservation International, and NatureServe, 2004, Global Amph. Assessment, suggested that all records for Cameroon apply to an undescribed species (now named Arthroleptis perreti) and that Arthroleptis adolfifriederici is restricted to East Africa. Records for Arthroleptis adolfifriederici from Kenya and Tanzania apparently refer to Arthroleptis affinis if Arthroleptis adolfifriederici leleupi is its synonym (see that comment). Channing and Howell, 2006, Amph. E. Afr.: 49–50, provided an account and map for East Africa. Frétey, 2008, Alytes, 25: 99–172, summarized the literature. Blackburn, Gonwouo, Ernst, and Rödel, 2009, Breviora, 515: 1–23, redescribed the species and compared it with nearby species. Blackburn, Gonwouo, Ernst, and Rödel, 2009, Breviora, 515: 1–23, restricted the range, noting that records from Kenya, Tanzania, and Malawi refer to other species. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 266–267, provided a brief account, photograph, and range map. Twahirwa, Faida, Tuyisingize, and van der Hoek, 2020, Herpetol. Notes, 13: 937–939, reported specimens from Volcanoes National Park, Rwanda, for the first time since 1941, between the volcanic peaks of Mount Bisoke and Mount Sabyinyo at 2700 m elevation. Dehling and Sinsch, 2023, Diversity, 15 (512): 1–81, discussed the range, identification, natural history, advertisement call, and conservation status in Rwanda.
