Two individuals heard in a dense pile of chopped branches, less than 1m above ground level. They could not be seen and the spot was impossible to access up close.
Tentatively Raorchestes shillongensis.
Help required to rule out R. longchuanensis, R. cangyuanensis and others from the 'parvula' group that have been recorded in NE India/Bangladesh.
S-V length approx. 1cm. Found in low bushes at a secondary forest edge bordering a hilltop grassland.
Gap of about 40 seconds between first and second sequence of calls.
Second specimen of Critically Endangered, R. shillongensis observed. Characterised by its distinctive 'X' or ')-(' or ')(' (or hourglass) like marking on its dorsum. Compared to my first specimen https://www.inaturalist.org/observations/80336036
this one has a brownish grey shade and is slightly bigger in size, though roughly only about the size of a thumb nail. Very difficult to spot due to its rarity, tiny size and well camouflaged markings.
The specimen has a pinkish-light brown dorsal ground colour, and seven darker brown dorsal-dorsolateral stripes. The median dorsal stripe is discontinuous along the dorsum, and does not pass onto the headplate. The only other seven-striped species (probably) is a Diversibipalium from Nantou County Taiwan that has slightly different configuration of the longitudinal stripes, and in which the median dorsal stripe terminates on the headplate. The specimen from Shillong differs from Bipalium kewense in lacking a black incomplete transvers band just below the headplate, and in having seven stripes (five on B. kewense), and differs from D. multilineatum in that the median dorsal stripe does not terminate on the headplate, and having seven, not five dorsal stripes. The rounded posterior tip on the Shillong specimen suggests that it could be reproducing asexually by fission.
