Abstract: Planetary extinction of biodiversity underscores the need for taxonomy. Here, we scrutinizespider taxonomy over the last decade (2008–2018), compiling 2083 published accounts of newlydescribed species. We evaluated what type of data were used to delineate species, whether data weremade freely available, whether an explicit species hypothesis was stated, what types of media wereused, the sample sizes, and the degree to which species constructs were integrative. The findings wereport reveal that taxonomy remains largely descriptive, not integrative, and provides no explicitconceptual framework. Less than 4% of accounts explicitly stated a species concept and over one-thirdof all new species described were based on 1–2 specimens or only one sex. Only ~5% of studies madedata freely available, and only ~14% of all newly described species employed more than one line ofevidence, with molecular data used in ~6% of the studies. These same trends have been discovered inother animal groups, and therefore we find it logical that taxonomists face an uphill challenge whenjustifying the scientific rigor of their field and securing the needed resources. To move taxonomyforward, we make recommendations that, if implemented, will enhance its rigor, repeatability, andscientific standards.
