RESUMO
The genus Simopelta consists of 21 described species restricted to Central America and South America. The present study describes a new cryptobiotic species, Simopelta anomma sp. nov.. The new species is blind, possesses a 3-segmented antennal club, and has the midtibia with several stout setae, a combination of characters unique within the genus. Moreover, some traits of this species require broadening the definition of the genus. The discovery of S. anomma sp. nov. suggests that many undiscovered species, some of which may be important for understanding ant evolution, remain hidden below ground in Neotropical rainforests.

The species of the predatory ant genus Gnamptogenys Roger, 1863 from Colombia (42 species) and Ecuador (25 species) are diagnosed and presented, including their known geographical distribution. Gnamptogenys enodis, new species from Colombia is described. Gnamptogenys stellae Lattke, 1995 is new record for Colombia.

RESUMO
141 genera of Sphecidae, representing 1,628 species, are known from the Neotropical Region. Illustrated keys to genera, tribes, and subfamilies are presented in Spanish and English. These have been modified and updated from those in Bohart & Menke's 1976 book, Sphecid Wasps of the World. The validity of a few genera recognized by Bohart & Menke is now in question and the keys are annotated to alert users to these problems. A list of neotropical genera and higher taxa is included. Names in the list are appended with significant literature published since 1976. The history and current status of subfamilies are reviewed. Ten subfamilies are recognized. Family characters and biology are summarized. morphological terms are illustrated and a glossary provided
