Trend charts of approximately 0.4 percent of the animal kingdom indicate that the describing and naming of species, "alpha taxonomy," is far from completed. 

Patterns in species description: a case study using the Geometridae (Lepidoptera)

The dynamics of description of geometrid moths, one of the most speciose families of Lepidoptera, is explored, finding patterns provide an important foundation from which to explore underlying spatial patterns in the species richness ofSpeciose higher taxa.

Accumulating knowledge on the dimensions of biodiversity: systematic perspectives on Neotropical mammals

In addition to earlier-noted problems of esti- mating diversity by this approach, variation in body size, geographic range size, and geographic provin- cialism all serve to make organisms differentially apparent to sampling efforts.

Evaluating Alpha and Beta Taxonomy in Ant-Nest Beetles (Coleoptera, Carabidae, Paussini)

Analysis of trends in synonymies suggest that few currently accepted taxa will be recognized to be synonymous in the future, which may indicate that Paussini are a taxonomically relatively stable tribe of carabid beetles.

Predicting unknown species numbers using discovery curves

The results suggest that unless the inventory of a group is nearly complete, estimating the total number of species is associated with very large margins of error and the strong influence of unpredictable variations in the discovery process on species accumulation curves makes these data unreliable in estimating total species numbers.

Review of the species of Achias (Diptera : Platystomatidae)

A method of estimating the approximate number of undiscovered species is presented, and indicates that the register of Achias species is very incomplete, and certain taxonomic characters are discussed related to taxonomic placement of the genus, informal infrageneric groupings of species, and species delimitation.

Estimating the global species richness of an incompletely described taxon: an example using parasitoid wasps (Hymenoptera: Braconidae)

Two independent methods are used to predict the global species richness of the subfamilies of the parasitic wasp family Braconidae, and there is a significant correlation between the proportions of undescribed species predicted by each method.

Significance of Specimen Databases from Taxonomic Revisions for Estimating and Mapping the Global Species Diversity of Invertebrates and Repatriating Reliable Specimen Data

It is demonstrated for a specimen database assembled during a revision of the robber‐fly genus Euscelidia how nonparametric species richness estimators can be used to estimate global species diversity and assess whether the plant‐based global biodiversity hotspots of Myers et al. (2000) contain a significant proportion of invertebrates.

Fathoming tropical biodiversity: the continuing discovery of Neotropical mammals

By analysing nomenclature for Neotropical mammals, two well-defined biases are documented that are associated with species accumulation: definite trends in body size are evident, so that larger organisms were more quickly apparent to systematists.

Analysis of the species description process for a little known invertebrate group: the limnoterrestrial tardigrades (Bilateria, Tardigrada)

The analysis indicates that insufficient efforts have been invested in the tardigrades compared to other invertebrates, and that there is a need for more taxonomists and more extensive sampling areas.

Tackling the taxonomic impediment: a global assessment for ant‐nest beetle diversity (Coleoptera: Carabidae: Paussini)

Although relatively few species are expected to be described in the future, the species accumulation curves indicate that the taxonomic inventory is not yet complete, and differences in accumulation patterns among biogeographical regions can be used to highlight the areas where morespecies are expected, and hence where taxonomical efforts should be concentrated.
