Hyperolius spinigularis Stevens, 1971  

H. spinigularis from Northern Tanzania comprise a separate genetic group from H. spinigularis from Mount Mulanje in Malawi (Lawson, 2010 in review). The two clades are very similar, though both males and females from Malawi are slightly larger, have more spines, and appear to lose their spines outside of the breeding season (Tanzanian specimens are reported to retain spines). The ranges of H. tanneri and H. minutissimus fall in the intervening area between these two distant H. spinigularis clades, and are often mistaken for H. spinigularis.
