species cumulative curve
numbers suggest that - given the resources - it will be possible
to describe a large percentage of the roughly 2500 undescribed species
9 (still valid) species of Pholcidae were described in the first 100
years after Linné,
compared to almost 1500 species in the last 100 years.
known species (over 1000) have been described in the last 17 years.
