Evertebrata Varia

The collections range from protozoans (Foraminifera) to more highly evolved worms (Annelids). Research activities contribute to the Senckenberg Research Field Biodiversity and Systematics.

As a parasitologist I am interested in all kind of parasites …. 
starting with intracellular protozoic parasites through to parasitic arthropods … and their hosts!
That is why I was biomonitoring the endangered species Hirudo medicinalis (European medicinal leech) in Saxony/Germany for one thing and for another thing I’m taking part in a mapping project to investigate the mosquito populations of Germany, with focus on invasive species that might spread diseases.  

Non-parasitic – but extraordinar – invertebrate species also can arouse my interest …

2012 – 2013 – 2014 …
As a co-worker of an the well known Onychophora research project directed by Dr. Georg Mayer, University of Leipzig and the most notably Ivo de Sena Oliveira, Andreas Weck-Heimann was able to focus on the disregarded morphological diversity of velvet worms (Onychophora) by use of the scanning electron microscope ZEISS EVO 50 in operation at the Senckenberg Institute in  Dresden since 2006 . 

In 2012 we identified a new species and genus from Costa Rica Principapillatus hitoyensis gen. et sp. nov. , Velvet Worm – Onychophora.

And here comes next new Velvet Worm from Vietnam in 2013 …

Another new Onychophora species has been described in 2014
