Ptychadena nana

Appearance

Adult males measure 24–27 mm (0.9–1.1 in) and adult females 25–30 mm (1.0–1.2 in) in snout–vent length, or respectively 30–33 mm (1.2–1.3 in) and 32–35 mm (1.3–1.4 in), according to Freilich and colleagues.

Common names Somali grassland frog and smallest grass frog have been coined for it.

Range and habitat

It is only known with certainty from its type locality, Arussi Mountains, in the Ethiopian Highlands. These mountains are also referred to as the Arsi Mountains. There is uncertainty regarding reports from elsewhere (in particular, Bale Mountains), that perhaps refer to other, possibly undescribed species. Freilich and colleagues found specimens from the Bale Mountains to be larger than "normal" Ptychadena nana, but that molecular data clustered them with other P. Nana.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Breeding

Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.

Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.

In crisis

In the IUCN Red List of Threatened Species, Ptychadena nana is listed as "endangered" because of its small known range and threats to its habitat.

Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.

Ptychadena nana is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
