Arthroleptis spinalis Boulenger, 1919 TANGANYIKA SCREECHING FROG

Arthroleptis spinalis Boulenger 1919b:187 . Holotype: MRAC (collector Stappers), fide R. Laurent in Frost

(1985:20). Type locality: “la plaine Saint-Louis, au Lake Tanganyika” ( Boulenger 1919b:187), [= St. Louis

Plain on the western shore of Lake Tanganyika] Democratic Republic of Congo. Athroleptis boulengeri : Laurent (1950a:15). Schoutedenella spinalis : Cei (1977:16). Arthroleptis spinalis : Frétey et al. (2011:22), Frost (2016).

Global conservation status (IUCN): Data Deficient.

Global distribution: The species is known from northern Angola and the eastern Democratic Republic of Congo.

Ocurrences in Angola (Map 64): The species has one record in the northeast of the country. Lunda Norte: “Dundo, galerie forestière de la Luachimo” [-7.38333, 20.83333] ( Laurent 1950a:15) .

Taxonomic and distributional notes: Boulenger (1919a) described Arthroleptis spinalis from eastern Democratic Republic of Congo, which is generally recognized as the only known locality for this species ( Frétey et al. 2011, Frost 2016). However, Laurent (1950a) cited Arthroleptis boulengeri ( de Witte, 1921) from northeastern Angola and then later recognized this species as a junior synonym of A. spinalis (Laurent 1954) . If correct, this suggests that this species may be more widespread throughout northern Angola and southern Democratic Republic of Congo. MAP 64. Distribution of Arthroleptis spinalis in Angola.

Arthroleptis stenodactylus Pfeffer, 1893 COMMON SQUEAKER

Arthroleptis stenodactylus Pfeffer 1893:93 , pl. 1, fig. 11. Holotype: ZMH, presumably destroyed in World War

II (collector F. Stuhlmann). Type locality: “Kihengo” ( Pfeffer 1893: pl. I), Tanzania. Corachodichus stenodactylus : Frade (1963:254), Cei (1977:16). Corachodichus stenodactylus stenodactylus : Laurent (1964a:144). Arthroleptis stenodactylus : Ruas (1996:28, 2002:145), Channing (2001:46), Frétey et al. (2011:25), Frost

(2016).

Global conservation status (IUCN): Least Concern.

Global distribution: The species is broadly distributed from Kenya and Tanzania, west into the Democratic Republic of Congo and Angola, and south through Zambia, Zimbabwe, Malawi, Mozambique, and extreme northeastern South Africa.

Ocurrences in Angola (Map 65): The species is known only for Moxico Province.

Moxico: “Calombe, Luso” [-11.83333,

19.93333] ( Ruas 1996:28, 2002:145; Channing

2001:47); “Cazombo” [-11.88333, 22.91667]

[-12.11667, 23.46667] ( Laurent 1964a:144;

Ruas 1996:28; Channing 2001:47). Undetermined Locality: “areas of forest and savanna in the north and northeast of Angola ” ( Cei

1977:16); “Zambezian highlands” ( Frade

1963:254).

Taxonomic and distributional notes:

According to Ruas (1996), Arthroleptis stenodactylus Pfeffer, 1893 in Angola occurs only in the east of the country. Previous authors

(e.g., Channing and Howell 2006; Pickersgill MAP 65. Distribution of Arthroleptis stenodactylus in Angola.

2007a) have suggested that multiple distinct species exist within what is referred to A. stenodactylus , and preliminary molecular genetic data provides some support for this ( Blackburn 2008). It is not yet clear to which of these cryptic species these Angolan populations might correspond.

Arthroleptis xenochirus Boulenger, 1905 PLAIN SQUEAKER

Arthroleptis xenochirus Boulenger 1905:108 , pl. 4, figs. 2, 2a. Holotype: BMNH 1947.2 .30.54 (collector

W.J. Ansorge), formerly 1904.5.2.101, fide R. Laurent in Frost (1985:20). Type locality: “Marimba”

(2011:25), Frost (2016), Ceríaco et al. (2016b:23).

Global conservation status (IUCN): Least Concern.

Global distribution: A wide-ranging species found in northern Angola, the southern Democratic Republic of Congo, northern Zambia and possibly southwesternmost Tanzania.

Ocurrences in Angola (Map 66): The species occurs in northeastern Angola. Lunda Norte: “Dundo” [-7.36667, 20.83333] (Laurent 1950:15). Lunda Sul: “Poste de Cacolo, Alto Cuílo, galerie forestière du Tchá-Muchito, sous affluent du Cuílo” [-10.01667, 19.45000] ( Laurent

Undetermined Locality: “areas of forest and savanna in the north and northeast of Angola ”

( Cei 1977:16).

Taxonomic and distributional notes:

This species is well documented from northeastern Angola. Given past taxonomic uncertainties (e.g., Laurent 1964a; Poyton and MAP 66. Distribution of Arthroleptis xenochirus in Angola.

Broadley 1985a), it is possible that what is referred to as A. xenochirus across its currently recognized range may in fact represent more than one species.
