          The description process for North and Central American species of Geotrupinae was analyzed and compared with that of Western Palaearctic species. This process was fitted to an asymptotic function to explore when the curve stabilized. By means of GLMs, the influence of some variables from 3 different groups (body size, geographic range and location) was examined, taking into account both pure and combined effects on the development of the process of species description. The accumulation curve of North and Central American Geotrupinae showed that probably 84-91% of the total number of species is already known and 10-20 species remain yet to be described. Body size has not shown any influence on Geotrupinae species description for either region. The most influential elements were the pure effect of the geographic range, followed by the pure effect of the geographic location, and their combined effect. These same variables were also the most influential in the Western Palaearctic region, although with a different significance. As this species inventory remains yet to be completed, it is possible that some factors, such as distribution, could become progressively more important, as for the Geotrupinae species in the Western Palaearctic region.

          Se analizó el proceso de descripción de especies de Geotrupinae de América del Norte y Central y se comparó con el de las especies del Paleártico Occidental. Este proceso se ajustó a una función asintótica para explorar cuándo la curva terminaba estabilizándose. A través de GLMs, se examinó la influencia de 3 tipos diferentes de variables (tamaño corporal, rango geográfico y localización) en el proceso de descripción, teniendo en cuenta sus efectos puros y combinados. La curva de acumulación de Geotrupinae de América del Norte y Central mostró que probablemente se conoce un 84-91% del número total de especies y que quedarían 10-20 especies por describir. El tamaño corporal no mostró ninguna influencia en los procesos de descripción de Geotrupinae. Los elementos más influyentes fueron el efecto puro del rango geográfico, seguido por el efecto puro de la localización geográfica y el efecto combinado entre ambos. Éstos fueron también los más significativos en el proceso de descripción de Geotrupinae en el Paleártico Occidental, aunque con una importancia relativa diferente. Como el inventario de especies de Geotrupinae norte- y centroamericanos aún se encuentra incompleto, es posible que algunos factores, como el rango de distribución, sean progresivamente más importantes, como sucede en las especies de Geotrupinae del Paleártico Occidental.

            R M May (1988)
            This article surveys current answers to the factual question posed in the title and reviews the kinds of information that are needed to make these answers more precise. Various factors affecting diversity are also reviewed. These include the structure of food webs, the relative abundance of species, the number of species and of individuals in different categories of body size, along with other determinants of the commonness and rarity of organisms.
