==Appearance==

Hyperolius Nitidulus are medium-sized reed frogs with a rather blunt snout. Males vary is size between 23mm and 29mm and on average weight about one gram.〔 Females are larger and heavier than males, their body size can vary between 24mm to 32mm with an average weight of about two grams before laying eggs. This species has a large Choana, which is not hidden beneath edge of mandible like in most Hyperolius species.〔 They have a relatively large tongue which is broad and shaped like a heart. Their dorsal view is roundish and sometimes a bit pointy.〔 From a lateral view their body is flattened but some have a round truncate. The position of the naris is slightly close to snout tip than to the eye. Skin is laterally smooth and with small warts. Body is slender and half cylindrical with thin limbs. They have extra skin folds that are used to hide their feet while aestivating during dry conditions. Finger and toes have circummarginal disc.〔 Males have a median subgular vocal sac which is used for calling.〔

During their juvenile stage their color is beige with a darker lightly flanked stripe at the side from snout to vent. As an adult they exhibit metachrosis (change in color), this color change is based on many factors such temperature, humidity. During the night the uniformly color is beige and during the day the color can vary between yellow and orange with spots.〔 During the dry season the juveniles become white as they aestivate the skin in the inside of their limbs becomes red due to the underlying capillary network. Hyperolius Nitidulus is mostly found in the Savannas of Western Africa, South of Sahara, and Grasslands. Adults are insectivores they usually consumed species such: Drosophila, Musca, Phormia, Lucilia and Calliphora.〔
