Abstract The well-diversified Latin American agriculture plays an essential role in the economy of that region, through the export of food and agricultural commodities. The region is expected to

What shapes ground beetle assemblages in a tree species-rich subtropical forest?

Ground beetles seem to respond differently to environmental variables than ants and spiders, two other predominantly predatory arthropod groups that were studied on the same plots in the study area and which showed distinct relationships with woody plant richness.

Taxonomic etymology – in search of inspiration

An overview of possibilities of how and where taxonomists can find the inspirations that will be consistent with the ICZN rules is given and more detail afterthought about the naming process itself, the meaningful character of naming, as well as the recognition and understanding of names is generated.



A New Genus and Species of Lachnophorini and Two New Species of Lebiini from Costa Rica (Coleoptera: Carabidae)

Abstract A new genus and new species of Lachnophorini and 2 new species of Lebiini from Costa Rican are described (type localities in parentheses): Quammenis spectabilis, n. gen., n. sp. (type


The purposes of this paper are to set forth objectives of the long term Agra study, provide some information for collectors, encourage loan of material, and make known a new species from Panama in need of a name for another publication.

Arboreal Beetles of Neotropical Forests: Agra Fabricius, Larval Descriptions with Notes on Natural History and Behaviour (Coleoptera, Carabidae, Lebiini, Agrina)

Using a mobile crane system in a rain forest in southern Venezuela, adults of several species of Agra Fabricius were observed and captured and it is hypothesized that Agra larvae live under bark and are predatory.

The mixta, virgata, feistshameli and ohausi groups constitute Section Feisthameli of the lebiine genus Agra, and a key to these groups is provided.

Agra, arboreal beetles of Neotropical forests: famula group of formicaria group systematics (carabidae)

Two species groups of Agra, whose cumulative ranges extend from southernmost Texas to northernmost Argentina, are discussed and a clear understanding of phylogeny and distribution of these beetles may provide very good data with which to test recently proposed hypotheses of tropical species richness and endemism.

Agra, arboreal beetles of Neotropical forests: palmata‐group systematics (Carabidae)

This paper discusses one species group, palmata, of Agra, whose cumulative ranges extend from southernmost Texas to northernmost Argentina, and is divided into six subgroups: dominula, cavei, dora, tingomaria, valentina and palmata.
