A new taxonomist-curated reference library of DNA barcodes for Neotropical electric fishes (Teleostei: Gymnotiformes)
<p>DNA barcoding is a useful tool for identifying species; however, successful barcode-based identification requires a reference library of barcode sequences from accurately identified specimens. Here we present a reference library of <em>co1</em> barcode sequences for the Neotropical electric knifefish order Gymnotiformes (Teleostei: Ostariophysi), a model taxon for studies of tropical diversification and biogeography, genomics, behaviour, and neurobiology. Our library contains barcodes for 167 of the ca. 270 valid species of gymnotiforms derived from geo-referenced museum voucher specimens, and includes sequences from 26 type specimens and 21 specimens from type localities, most of which we collected. To assess the state of gymnotiform barcodes in two main public barcode repositories, GenBank and BOLD, we compared the barcodes in these databases to our reference library. Our analysis shows that a considerable proportion of gymnotiform barcodes in GenBank and BOLD are mis- or unidentified. We encourage taxonomists to develop and publish barcode reference libraries composed of carefully curated barcode sequences.</p>

Data from: More taxonomists describing significantly fewer species per unit effort may indicate that most species have been discovered
Recent studies show that there are more taxonomists describing species in recent decades than before. However, whether the rate of increase in number of taxonomists is greater than the rate of new species description has been questioned. We found a statistically significant decline in the proportion of species being described per number of taxonomists (i.e. authors of recent species descriptions) during the past century for (a) families of insects that had been stated not to show this trend, and (b) a sample of over 0.5 million marine, terrestrial and freshwater species. We suggest that this decreased 'catch' of species per taxonomic effort, despite scientists' greater ability to explore and sample habitats, means it is getting harder to discover new species, and supports recent studies suggesting that two-thirds of all species have been named.
FIGURE 21 in A review of the taxonomy and osteology of the Rhombophryne serratopalpebrosa species group (Anura: Microhylidae) from Madagascar, with comments on the value of volume rendering of micro-CT data to taxonomists
FIGURE 21. Comparison of (a) surface and (b) volume rendering of the same skeletal region of the same specimen; the acetabulum of Rhombophryne serratopalpebrosa (MNHN 1975.24). The surface rendering is that used in Scherz et al. (2014). The volume rendering was produced for this study. Note particularly the unossified state of the pubis in (b) compared to that reproduced in (a). The arrow indicates the end of the urostyle, which gradually thins towards its tip, but is shown to end abruptly in surface rendering due to the on/off characteristic of meshes.
