onychoporaOnychophora are ancient species with high importance for biodiversity research. They live in primary tropical rain forests on probably all the small Indonesian Islands. On Java and Sumatra no Onychophora have been found in more or less systematic expeditions. They have been found, however, in the Malayan part of Kalimantan (Eoperipatus sp.). The Indonesian part has apparently not yet been investigated. There is no information on Onychophora in Sulawesi.

The group of Prof. Georg Meyer at Kassel University is specialized on the systematics, morphology and cell biology of Onychophora (website Meyer-Group). He is very interested in collaborations to find, describe and analyze new species in Indonesia.

Collaborations could include exchange visits and training in state-of-the-art methods in systematics and immune-histochemistry.


Further measures

IGN partners who are working on rain forest biodiversity and planning excursions in Sulawesi, Kalimantan and the smaller islands may include Onychophora in their searches. Upon request, Prof. Meyer will supply hints and instructions how to find and how to handle Onychophora.

Specifics of potential collaborations will be negotiated in the case that new species are found. The IGN coordinator is available to support such negotiations.


It may be of interest to invite Prof. Meyer to one of the next conferences on biodiversity in Indonesia. At this point, travel expenses have to be covered by the Indonesian side. If successful collaborations emerge it will probably be rather easy to obtain funding from Germany.

Please inform the IGN coordinator if you are interested and can provide funding for a conference visit.
