Hylarana celebensis ( Peters, 1872)

( Figure 2 (c))

Description

Adult males, SVL 48.4 mm; head longer than wide (HL/HW = 1.06); nostrils closer to the tip of the snout than to the eyes, loreal region almost concave; tympanum round, distinct, almost equal to eye diameter (TY/EY = 0.90, TY/SVL = 0.016); vomerine teeth present, short; there is a distinct dorsolateral fold. Disks of fingers and toes are small, clear; length of fingers (longest to shortest) 3> 1> 4> 2, third finger disk diameter (F3D) with ratio of F3D/SVL about 0.063; the formula for the web of the toe, I 1 / – 1 II 0 – 11 / III 0 – 2 IV 2 – 0 V, follows that used by Savage and 2 2 Heyer (1997); length of tibia, ratio of TL/SVL about 0.526; length of toe (longest to shortest) 4> 5> 3> 2> 1; subarticular tubercles developed; inner metatarsal is oval; outer metatarsal is very small. Dorsal surfaces are brown; there are dark lines on the limbs.

Habitat

Several males were observed among herbaceous plants in the lake margin, calling during the first survey in plots 7 and 8. The presence of this species is easily determined because males vocalise in large groups ( Kurniati 2016). This species is often found actively jumping among plants in the lake margin. It was found active from 19 to 21°C and at 86 – 99% humidity.

Remarks

This species was observed in the lowlands (<700 – 800 m asl) in the central and northern parts of Sulawesi ( Iskandar and Mumpuni 2004; Wanger et al. 2011). However, our results indicate that this species also occurs from 1650 to 1700 m asl in the open areas used for camping (plots 7 and 8), and in primary forest (plot 4). This species was also found on Buton Island and other surrounding islands ( Gillespie et al. 2005), in the Nantu Gorontalo Wildlife Reserve and surrounding areas ( Khairunnisa 2014) at 600 m elevation, and in Pohuwato Gorontalo Forest ( Subasli 2015).
