We provide a map of the 15 biogeographic provinces of Argentina based on the ecoregions recognized for the country, combining climatic, geological and biotic criteria. Argentinean provinces belong to the Neotropical region (Yungas, Paraná Forest, Araucaria Forest, Chaco and Pampean provinces), the South American transition zone (Puna, Monte, Comechingones and Cuyan High Andean provinces) and the Andean region (Patagonian, Maule, Valdivian Forest, Magellanic Forest, Falkland Islands and Magellanic Moorland provinces). In order to facilitate future biogeographic analyses, we provide a file of this biogeographical regionalisation in vector format using the World Geodetic Survey 1984.

A New Species

A new species of Arthrobrachus Solier, A. arquatus n. sp. from Argentina, is described using external characters of the adult male and female including terminal segments of the abdomen and genitalia. Arthrobrachus arquatus n. sp. is morphologically close to A. tibialis Solier, 1849 from the Central Chile sub region, suggesting a phylogenetic connection. Comments on the possible origin of this relationship are made.

High Species Richness

The Miridae (Hemiptera: Heteroptera) are one of the most species rich families of insects, with about 11 100 described species. Mirinae is the largest subfamily and its endemism becomes evident at the tribal level and below. Mirines of the tribe Restheniini are found throughout America, with most of the diversity confined to the Neotropics. Prepops Reuter is the largest genus in Restheniini with 198 described species and its geographical range is similar to that of the tribe. The study of the distribution and areas of endemism in Miridae are scarce and non-existent for Prepops. We analyzed all the geographic records of Prepops (707 records for 181 species) in order to identify diversity patterns and areas of endemism, using network analysis. Locality data were assigned using museum specimens and geographic records in the literature. Additionally we used spatial data to propose habitat preferences and geoclimatic variables important for each group of co-occurring species. The results indicate high species richness in subtropical regions, while the tropical belt and high latitudes appear impoverished. The Neotropical region contains 86% of the species, and the Nearctic about 11 % (but with larger species ranges); the Andean region is sparingly represented. Twenty-three areas of endemism (and two diads), formed by 2 or more endemic species, are distributed in the Nearctic (3), Mexican Transition Zone and Caribbean subregion (5), South American Transition Zone and Amazonian, Chacoan and Paranaense subregions (15). Overlap between some of the areas indicates regions with high species richness and complex history. The lack of records from the Andean region (except for P. nigrus in Southern Patagonia) and dominance of strictly Neotropical species (86 %) supports the hypothesis of a Neotropical origin for the tribe Restheniini. The general arrangement of the units of co-occurrence of Prepops species shows a close correlation with known biogeographic regions and subregions. Broad physiographic characteristics most commonly associated with Prepops geographical records are, in order of importance: broad leaf forests (wet and dry), grasslands and xeric habitats.

The monotypic genus Jodina is endemic from central to south-eastern South America, where it grows from southern Bolivia and Brazil, Uruguay, to northern and central Argentina. The only species included in the genus is Jodina rhombifolia, a small hemiparasitic tree about 4–8 m high that is characteristic of the chacoan environments of the Neotropical region and Monte from the South American transition zone. As part of the floristic updates in the Neotropical and Andean regions of South America, the nomenclature of taxa related to Jodina rhombifolia was re-examined. Owing to the morphological and anatomical differences observed, and the well-delimited geographical distribution patterns that suggest the existence of two distinguishable subspecific entities, a new subspecies of Jodina rhombifolia is proposed here. Two lectotypes are designated and the nomenclature is clarified. An identification key, complete descriptions of the taxa and geographical distribution of the subspecies are also provided.

A new genus of springtail, Sernatropiella gen. nov., from Cundinamarca province, Colombia, was found at an altitude close to 3.000 m above sea level. It is the largest Neanuridae known in the Northern part of the South American Transition Zone. It is characterized by the presence of a strong hypertrichosis, five eyes per side, very small moruliform postantennal organ and a long buccal beak. Mouth parts very thin and slender. Body with paratergal areas different from other Pseudachorutinae of the region. Thorax and abdominal segments I and II with pre- and post-segmental tergites with setae, and most remarkable is the presence of pseudocelli on head, thorax and abdomen of the type species Sernatropiella pinzonae gen. et sp. nov. A new combination for Neotropiella malkini Arlé, 1981 as Sernatropiella malkini (Arlé, 1981) comb. nov. is given and is considered as a member of the new genus.
