67, 86, 90, 152, 153, 166.
Distribution in the KTM Valley
: Encountered at Nagarkot, Godawari, Shivapuri National Park west and east.
Pokhrel et al. (2011)
also reported this species from Nagarjun NP.
Remarks
:
Nanorana liebigii
is relatively common in forested areas with streams; we encountered seven adult individuals at four localities, and two larvae (
Table 2
,
Figure 1
). Individuals were most commonly encountered 1
–
5 metres from running water, within the forest, although one individual was next to a road along a waterway. When approached, individuals were not calling and did not move when approached. The tadpoles were encountered in a fast-moving stream in dense forest (
Figure 2
(e)). We encountered all seven adults near slow-moving streams. We always found this species in sympatry with
Megophrys zhangi
(
Figure 1
). Reproductive males usually exhibit secondary sexual traits such as keratinised pectoral spines, spines on the fingers and metacarpal tubercle, and exhibit a swollen anal region in the form of a circular bladder (
Schleich and Kastle 2002
;
Ohler and Dubois 2006
). However, none of the five adults we encountered exhibited these characters, possibly because we surveyed after the active breeding season (
Figure 2
(d)). Past work has relied on variable morphological characters to distinguish
Nanorana
in this region (
Ohler and Dubois 2006
); we hypothesise that future studies using molecular sequence data will likely uncover cryptic species within the KTM Valley.
