| Limnonectes limnocharis complex (WG044, WG040 5606 5600 5601 WG023 WG024*) We recognised three types of Limnonectes, based on differences in appearance and calls. Types 1 and 2 appeared identical but made different calls. Because non-calling individuals could not be distinguished the two types were classed together as L.limnocharis. The two calls were never heard together, although at Site 4 they called close to each other. Type 1 called at all sites except site 6, always close to the edge of the lake. Elsewhere they were found in puddles. Type 2 called at sites 4 and 5, calling from puddles in cattle hoof prints. Limnocharis frogs at Site 6 were not calling. Mean mass of 62 males of both types was 2.7g (+/- 1.1). Neither type appeared territorial and males were observed calling in close proximity to each other. Pitfall trap data indicated that Limnonectes (types 1 and 2) were equally common in coffee plantations and uncultivated habitats. Type 3 Limnonectes, represented by two animals (WG023, WG044) found in coffee plantation, were much larger than the other races (mass = 6g and 15.5g, SVL = 45mm and 56mm) and had almost no webbing on the hind feet. Its call was not heard. Tadpoles here belong to the "limnocharis complex". Call 1 |

The call of “typical” L. limnocharis has energy concentrated between 0.93 and 3.75 kHz with a dominant frequency at 1.44kHz and strong spectral sideband at 3.04kHz. Individual calls last about 0.07 seconds and contain 9-13 pulses, each lasting about
0.004 seconds.
