Onuphidae Kinberg,1865
Onuphidae species known from the region were reviewed by Orensanz (1990) and we recommend users this taxonomic resource for detailed drawings, descriptions and discussion. Species recorded from this study were all assinged to the known species and are therefore only briefly described in this guide (see Orensanz (1990) for details).
