Taxonomy. Glauconycteris egeria Thomas, 1913,

A. Hassanin and colleagues in 2018 showed that G. egeria was not monophyletic, with part sister to G. poensis and part sister to G. alboguttata. Monotypic.

Distribution. Known only from four localities, including type locality and Buea in SW Cameroon, Dzanga-Sangha Special Reserve in SW Central African Republic, and Budongo Forest in W Uganda.

Descriptive notes. Head-body ¢.46-50 mm, tail 35-48 mm, ear 12-19 mm, forearm 37-39 mm; weight 5-5-7-5 g. Dorsal and ventral pelage are soft and dense, ranging from dark brown to almost black. Dorsal pelage is almost pure black in Uganda and sepia-brown in Cameroon. Conspicuous whitish dorsal flank-stripes are present. Ears are separated, subquadrangular in outline (rounded in other dark-winged Glauconycters), short for a vespertilionid but comparatively long and broad for a Glauconycteris, and dark brown, with conspicuously pale rim. Inner margin has long backward-pointing lobe at base, and outer margin is connected with rather small fleshy lobe on lower lip near corner of mouth. Eyes are very small. Wings and uropatagium are dark brown without reticulation. Tibia is short (16-18 mm) for Glauconycteris. Head is comparativelylarge and high-domed, and muzzle is short, broad, and flattish. Skull is small, and profile of forehead is concave compared with other Glauconycteris. I? is long and stronglybicuspid, with cusps equal in size. I” is minute. Lowerincisorsare tricuspid and not markedly crowded.
