Comment

Prior to the revision of Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297, placed in the Section Strongylopus, subgenus Afrana of Rana of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 334. The revision of Channing and Baptista, 2013, Zootaxa, 3640: 501–520, made it clear that nominal "Amietia angolensis" is a complex of species, with Amietia angolensis sensu stricto being restricted to Angola and the revision of Channing, Dehling, Lötters, and Ernst, 2016, Zootaxa, 4155: 1-76, partitioned former Amietia angolensis into several species, rendering older literature very difficult to use with any confidence. 

Literature dealing with any part of the range of the complex must be used with caution as several species clearly have traditionally been confounded. For purposes of completeness the following publications dealing with nominal Amietia angolensis are included here, but there is little evidence that the species treated are that species. See Poynton, 1964, Ann. Natal Mus., 17: 103-107; Perret, 1976, Arq. Mus. Bocage, Ser. 2, 6: 15-34; and Channing, 1978, Ann. Natal Mus., 23: 361-365, for diagnosis. See comment under Afrana fuscigula. Poynton and Broadley, 1985, Ann. Natal Mus., 27: 132-134, provided an account and doubted the earlier synonymy of Rana chapini Noble, 1924, by Laurent, 1972, Explor. Parc Natl. Virunga, Ser. 2, 22: 90. See also Lambiris, 1988, Lammergeyer, 39: 89-90. See discussion by Loveridge, 1933, Bull. Mus. Comp. Zool., 74: 362-364, regarding races. Containing many cryptic species according to Drewes and Vindum, 1994, J. Afr. Zool., 108: 65. See Channing, 2001, Amph. Cent. S. Afr.: 255-256, for account of southern African population.  Bauer and Branch, 2001, Herpetol. Nat. Hist., 8: 124-125, commented on confusion with Rana fuscigula and range in western South Africa. See also accounts by Pickersgill, 2007, Frog Search: 98-101, and Lötters, Wagner, Bwong, Schick, Malonza, Muchai, Wasonga, and Veith, 2007, Fieldguide Amph. Rept. Kakamega Forest: 17-18.See account, photograph, and map for Ethiopia by Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 160-162. Malonza, Lötters, and Measey, 2010, J. E. Afr. Nat. Hist., 99: 55, commented on range, life history, and conservation status in the Taita Hills of Kenya. Measey, Malonza, and Muchai, 2009, Amph. Taita Hills: 48-49, provided a brief account and photo for the Taita Hills, Kenya. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 318–319, provided information on comparative larval morphology. Harper, Measey, Patrick, Menegon, and Vonesh, 2010, Field Guide Amph. E. Arc Mts. Tanzania and Kenya: 276–277, provided a brief account and photograph.  Portik, Mulungu, Sequeira, and McEntee, 2013, Herpetol. Rev., 44: 396, provided records for Zambézia Province, Mozambique, but suggested some concern about taxonomic status. Ohler and Frétey, 2014, J. E. Afr. Nat. Hist., 103: 101, provided a brief discussion of a collection from northern Mozambique, that they referred to Amietia cf angolensis but thought might be Amietia queckettiLarson, Castro, Behangana, and Greenbaum, 2016, Mol. Phylogenet. Evol., 99: 168–181, suggested that Rana chapini will be found to be a distinct species. See account by Channing, Dehling, Lötters, and Ernst, 2016, Zootaxa, 4155: 15–21. Channing and Howell, 2006, Amph. E. Afr.: 250-252, provided an account for East Africa (as Afrana angolensis).  See Largen, 2001, Tropical Zool., 14: 331-332, for comments on distribution (as Rana angolensis). Mercurio, 2011, Amph. Malawi: 277-280, provided an account for Malawi (as Rana angolensis).
