on East Asian pholcids has substantially inreased species numbers,
especially in the large genus Pholcus,
but also in smaller genera like Belisana
- In Pholcus (currently 356 species) there is a
basic phylogenetic hypothesis (Huber 2011)
that identifies major species groups, suggesting an origin in southern
China, with more derived groups extenting north and to the Korean
Peninsula. Unfortunatly, subsequent work in the region has not built on
this foundation but reverted to adding names without much concern for
relationships and biogeographic patterns.
- In Khorata (currently 33 species), many
species have been described recently, but no phylogenetic hypothesis
has ever been proposed.
- In Belisana (currently 112 species),
the first and only cladistic analysis (Huber
2005) was an effort to place the genus within the family but taxon
sampling was inadequate for an analysis of intragereric relationships.
Recent works have added many new species, again never going beyod pure
This project focuses on the rich pholcid fauna of China and neighboring
countries. The main hypothesis is that in all three genera, Chinese and
Korean species have originated in the tropical south and spead and
diversified on their way to the north. Sound phylogenetic hypotheses
for each of the taxa are necessary to test this hypothesis.
The study will build on three main sources:
Planned trips 2017-2018.
- A large
collection of Chinese and Korean pholcids recently brought to my
attention. Unfortunately, all this material is preserved in 70% ethanol
and is thus not suitable for molecular work.
collecting trips will cover a transect of approximately 3000 km raging
from Yunnan to Shaanxi, from Shaanxi to Beijing, and from Beijing to
South Korea. The main goal of these trips is the collection of fresh
material for molecular work of as many taxa as possible.
species descriptions will be used in cases where no material is
