This species has a characteristic white spur on the heel. The dorsum is greyish with a dark, backward-pointing triangle on the head, and a broad dark dorsal band that is often split up into bars or lateral spots. There is also often a white spot under the eye. The canthus rostralis is angular. Webbing in the feet is extensive.[7] L. c. meridionalis differs from the nominate subspecies by the spur on the heel being less developed, by having more extensive webbing, and by other small morphological differences.[7]Habitat and conservationLeptopelis calcaratus is an arboreal frog found in lowland and montane rainforests at elevations from near sea level to {{convert|1500|m|abbr=on}} above sea level, possibly higher. It does not survive in secondary habitats. If similar to other species of Leptopelis, it would lay eggs in a nest on the ground near water. It is a common species but its habitat is affected by habitat loss caused by agricultural expansion, logging, and human settlements. It occurs in a number of protected areas, including the Korup National Park (Cameroon), Monte Alén National Park (Equatorial Guinea), and Dzanga-Ndoki National Park (Central African Republic).[1]References1. ^1 2 3 {{cite journal | author = IUCN SSC Amphibian Specialist Group | title = Leptopelis calcaratus | journal = IUCN Red List of Threatened Species | volume= 2013 | page = e.T56250A18387924 | publisher = IUCN | year = 2013 | url = https://www.iucnredlist.org/species/56250/18387924 | doi = 10.2305/IUCN.UK.2013-2.RLTS.T56250A18387924.en | accessdate = 10 November 2016}} [2][3][4]2. ^1 2 3 {{cite web |url=http://www.amphibiaweb.org/cgi/amphib_query?where-genus=Leptopelis&where-species=calcaratus|title=Leptopelis calcaratus |year=2008 |work=AmphibiaWeb: Information on amphibian biology and conservation.
