Hyperolius langi Noble, 1924

Class: Amphibia > Order: Anura > Family: Hyperoliidae > Subfamily: Hyperoliinae > Genus: Hyperolius > Species: Hyperolius langi

Hyperolius langi Noble, 1924, Bull. Am. Mus. Nat. Hist., 49: 252, 266. Holotype: AMNH 9983, by original designation. Type locality: "Niapu", Uele, Dem. Rep. Congo. Synonymy with Hyperolius platyceps by Laurent, 1957, Explor. Parc Natl. Upemba, Miss. G.F. de Witte, 42: 6.

Hyperolius albomarginatus Laurent, 1940, Rev. Zool. Bot. Afr., 34: 2. Holotype: MRAC 39948, by original designation. Type locality: "Mongbwalau (Ituri près de Kilo)", Dem. Rep. Congo. Synonymy by Laurent, 1950, Explor. Parc Natl. Albert, Miss. G.F. de Witte (1933–1935), 64: 51.

Hyperolius platyceps langi — Laurent, 1957, Explor. Parc Natl. Upemba, Miss. G.F. de Witte, 42: 6.

Hyperolius langi — Amiet, 1979 "1978", Ann. Fac. Sci. Cameroun, 25: 234-243.

Common Names

Lang's Reed Frog (Channing and Howell, 2006, Amph. E. Afr.: 165).

Distribution

From the vicinity of the type locality (Niapu, Orientale) in north-northeastern Dem. Rep. Congo to extreme eastern Dem. Rep. Congo (Nord-Kivu); expected Uganda.

Geographic Occurrence

Natural Resident: Congo, Democratic Republic of the

Likely/Controversially Present: Uganda

Endemic: Congo, Democratic Republic of the

Comment

The status of this nominal form is confusing. Schiøtz, 1999, Treefrogs Afr.: 147 and 149, suggested that populations from eastern Dem. Rep. Congo may actually be composite, including Hyperolius kuligae, and possibly identical with Hyperolius platyceps to the west. See comments by Köhler, Scheelke, Schick, Veith, and Lötters, 2005, Afr. Zool., 40: 135, who described the advertisement call. Channing and Howell, 2006, Amph. E. Afr.: 165–166, provided an account. Marques, Ceríaco, Blackburn, and Bauer, 2018, Proc. California Acad. Sci., Ser. 4, 65 (Suppl. II): 105, provided a map for Angola and a brief account, implying that the Angola record probably applies to Hyperolius bocagei. Mali, Banda, Chifundera, Badjedjea, Sebe, Lokasola, Ewango, Tungaluna, and Akaibe, 2019, Am. J. Zool., 2: 38–43, reported the species from the Okapi Wildlife Reserve, northeastern Dem. Rep. Congo. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 194–195, provided a brief account, photograph, and range map. See comment under Hyperolius kuligae. Badjedjea, Masudi, Akaibe, and Gvoždík, 2022, Amph. Rept. Conserv., 16 (1: e301): 52–54, commented on a population of Hyperolius cf. langi from the Kokolopori Bonobo Nature Reserve, Tshuapa Province, Dem. Rep. Congo, and the taxonomic questions they present. Dehling and Sinsch, 2023, Diversity, 15 (512): 65, specifically excluded this species from the fauna of Rwanda.
