Description

Adult males measure 23–29 mm (0.9–1.1 in) and adult females 28–37 mm (1.1–1.5 in) in snout–vent length. [4] [5] Males have extremely long third fingers. [6] The tympanum is visible. The dorsum is greyish brown and bears small and large symmetrical dark brown blotches with a pale outline. There are three large blotches; the first one is triangular and starts between the eyes, pointing backwards. Another two blotches follow immediately behind. [2]

Habitat and conservation

Cardioglossa elegans occur in moist lowland and degraded forests at elevations below 1,000 m (3,300 ft). Breeding takes place in small streams, and males call from rocky areas or from under bridges. [1]

Cardioglossa elegans is a common species where it occurs, especially when aggregating for breeding. It can probably suffer locally from habitat loss. It is likely to occur in several protected areas. [1]

Arthroleptis is a genus of frogs in the family Arthroleptidae found in tropical sub-Saharan Africa. Their common names include screeching frogs, sometimes simply squeakers.

<i>Cardioglossa</i> Genus of amphibians

Cardioglossa is a genus of frogs in the family Arthroleptidae known as long-fingered frogs. They are native to western and central Africa, with the greatest species richness in Cameroon. They are found near streams in lowland and mountain forests, but also occur in other highland habitats near streams at up to 2,700 m (8,900 ft) in altitude. These are small frogs with a snout–to-vent length of 2 to 4 cm (0.8–1.6 in). Some of the more localized species are threatened.

<i>Leptopelis</i> Genus of amphibians

Leptopelis is a genus of frogs in the family Arthroleptidae. They are found throughout Sub-Saharan Africa, excluding Madagascar. It is placed in monotypic subfamily Leptopelinae, although this subfamily is not always recognized. They have a number of common names, including forest treefrogs, tree frogs, leaf-frogs, and big-eyed frogs.

Arthroleptis carquejai is a species of frog in the family Arthroleptidae. It is known with certainty only from northwestern Angola, but there is also a recent record from Gabon. If this is correct, its distribution might also include intervening areas in the Republic of the Congo and the Democratic Republic of the Congo. The specific name carquejai honours Bento Carqueja, Portuguese professor, journalist, and philanthropist. Common names Cambondo screeching frog and Carqueja's squeaker have been proposed for it.

Cardioglossa alsco is a species of frog in the family Arthroleptidae. It is endemic to Cameroon and is known from its type locality on southern slopes of the Tschabal Mbabo Mountains as well as from the Gotel Mountains, both in the Adamawa Region. Its range might extend into Nigeria. The specific name alsco is a patronym for the American Linen Supply Company (ALSCO). The company's German branch supported the expedition during which this species was discovered.

Cardioglossa cyaneospila is a species of frog in the family Arthroleptidae. It is endemic to the Albertine Rift area in eastern Democratic Republic of the Congo, southwestern Uganda, Rwanda, and southwestern Burundi. It was described in 1950 by Raymond Laurent based on specimens collected in 1949. No new records were published until 2011. Recent research has uncovered both old unpublished records and several new records, and the conservation status was changed from "data deficient" to "near threatened" in 2016. Common names Bururi long-fingered frog and Mukuzira long-fingered frog have been coined for this species.
