Abstract:
The ranid genus Staurois contains three species of small fast—water frogs in Borneo (Inger 1966). Several members ofthe genus there and elsewhere have colourful hind foot webbing and for one of these, Staurois parvus ( = S. tuberilinguis), Harding (1982) has illustrated an unusual kicking display. This note records a similar display in a related species. A joint exercise involving the Brunei Armed Forces and British Army visited Ulu Temburong, east Brunei, from 10 to 31 January 1984. The main aim was a survey of higher vertebrates. Base camp was established on an inside loop of the fast flowing Temburong river one kilometre south of Kuala Temawai. At this point the river was 25 m wide, without waterfalls but with extensive rapids though which many boulders broke the surface. Water pH varied from day to day between 5.00 and 6.25, depending on rainfall. The frog Staurois latopalmatus (Boulenger) was the commonest amphibian at this site. Its call, a short rising trill, was heard throughout each night and during the early morning. Three collected while calling were all males. They emerged on to rocks projecting from the water soon after dusk, and remained active throughout the night. Frogs of similar size clustered together: one rock in slower water consistently hosted small juveniles, but most adults at night were solitary. Several individuals were seen almost every morning, for the first hour or two of daylight, and a few sightings were made at all hours of the day, even in brightsun.
