my first trip to West Africa (Guinea
2009), I had been eager to return to the area, many parts of which
are poorly explored with respect to spiders and pholcids in particular.
In February and March 2013 I finally had another opportunity to visit
West Africa, this time Ghana. Most of the time was spent exploring the
more humid southern forests (Ankasa National Park, Kakum National Park,
Atewa Hills, Akwapim Togo Range, Mampongtin Range).
As expected from
my previous trip to Guinea and from unpublished data, the diversity of
pholcids was relatively low compared to Central and Eastern Africa.
However, compared to what had been known before about Ghanaian
pholcids, the trip was a great success: only five species had even been
recorded from the country (published in Huber
2007 and Huber 2009), while this
trip alone resulted in 18 species. Since West African pholcids tend to
have wide geographic ranges, most of these species are known from
neighboring countries, but the trip also revealed several new species
like the ones shown below (from left: genera Leptopholcus, Smeringopina, Spermophora). In the meantime, all
these species have been described and an overview of West African
pholcids can be found in Huber
& Kwapong 2013.
many African countries, Ghana combines a wealth of different landscapes
and habitats, ranging from the humid rainforests in Ankasa in the
south to open savannah woodland in the north. While a single West
African rainforest may hold up to nine species of Pholcidae (Kakum
National Park), savannahs are definitely not places where pholcids have
diversified. I made a short side-trip to the north to visit my daughter
in Bunkpurugu (below, right), where she was doing voluntary work.
This photo here is a reminder that wearing good shoes in the forest makes a lot of sense. I stepped into this trap which was well hidden in the forest litter in Kakum National Park, but thanks to my boots nothing serious happened to my foot.
I owe thanks to Peter Kwapong for help with preparing the trip and with permits, and to Joseph Bosomtwe for being an extremely reliable driver, a helpful guide, and a good companion.
