Here some details regarding linkei and parvulus.
Horst Linke just reported to me that -among others – he found both species that he searched for. As linkei is concerned he confirmed my supposition that the undescribed spec. Seruyan probably is only a local form of that species (cf. our species account “linkei“). As parvulus is concerned he confirms our rather new knowledge of a very widespread distribution of that species, much more widespread that assumed by the first encounters with it last century. It is still present in a large range of wetlands around Palangkaraya, still in 200 km distance to the town. In the light of that evidence it is questionable if the distinctions of different local forms (like “Babugus” or “Tangkiling” that he and we talked about formerly, cf. our species account “parvulus“) is still to be valid, since the species is present nearly continously. We are not sure about this, however; there are for instance some big rivers separating parts of that region, and it remains to be investigated whether they function as separating the parts or rather as connecting them.
