Hyperolius concolor (Hallowell, 1844)
Variable Reed Frog, Uniform Reed Frog
© 2013 Daniel Portik (1 of 32)
Three subspecies were established by Schiøtz (1967), of which only two have been named:
2. Hyperolius c. ibadanensis Schiøtz 1967. – Many of the males have a distinct light canthal and dorsolateral line.
3. Hyperolius concolor ssp. – Apparently no males with distinct light canthal line.
This species shows developmental changes in patterning, with two phases, J (juveniles and many mature males) and F (mature females and some mature males). All newly metamorphosed individuals are phase J, which is normally brownish to green with paired light dorsolateral lines, or an hourglass pattern. All females, and some males, develop into phase F before the first breeding season. Phase F is often colorful and variable, showing the diagnostic color characteristics for the species or subspecies. Either well-defined morphs may be present, or graded variation.
The tadpole, with the usual dentition, has a dark stripe laterally from the root of the tail one-fourth to one-third towards the tip of the tail.
