It is found in the south-western Cameroon and in the extreme southern Nigeria at low altitudes. Common name blackspotted long-fingered frog has been coined for it.[1][2] DescriptionMales measure {{convert|24|-|26|mm|in|1|abbr=on}} and females, based on a single specimen, {{convert|32|mm|in|1|abbr=on}} in snout–vent length.[5] Males have extremely long third fingers and spines in the fingers and in the groin; females lack these characteristics.[6] Dorsal markings, typical for the genus Cardioglossa, consist of an hour-glass pattern, with a separate blotch on the head. The white line running under the tympanum terminates under the eye. Habitat and conservationCardioglossa nigromaculata occurs in lowland moist forests, as well as in degraded habitats near more mature forests, at elevations of {{convert|100|–|300|m|abbr=on}} above sea level. Individuals can be spotted in small groups along forest watercourses, often in undergrowth among dead leaves and in holes. Breeding presumably takes place in streams where the tadpoles develop.[1]Cardioglossa nigromaculata is fairly common species, but it is often missing from seemingly suitable habitat. The overall population is believed to be decreasing because of habitat loss caused by urbanization, agriculture, and logging. It occurs in the Korup National Park in Nigeria and in the Ebo Forest Reserve in Cameroon.[1]References1. ^1 2 3 {{cite journal | author = IUCN SSC Amphibian Specialist Group | title = Cardioglossa nigromaculata | journal = IUCN Red List of Threatened Species | volume= 2017 | page = e.T89186860A49312036 | publisher = IUCN | year = 2017 | url = http://www.iucnredlist.org/details/89186860/0 | doi = 10.2305/IUCN.UK.2017-2.RLTS.T89186860A49312036.en | accessdate = 15 May 2018}} [2][3][4]2. ^1 {{Cite journal |last=Blackburn |first=David C. |date=2009 |title=Diversity and evolution of male secondary sexual characters in African squeakers and long-fingered frogs |url=https://academic.oup.com/biolinnean/article/96/3/553/2452743 |journal=Biological Journal of the Linnean Society |volume=96 |issue=3 |pages=553–573 |doi=10.1111/j.1095-8312.2008.01138.x}} 3. ^1 2 {{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/index.php//Amphibia/Anura/Arthroleptidae/Arthroleptinae/Cardioglossa/Cardioglossa-nigromaculata |title=Cardioglossa nigromaculata Nieden, 1908 |author=Frost, Darrel R. |year=2018 |work=Amphibian Species of the World: an Online Reference.
