Genus Castianeira Keyserling, 1879

Type species: Castianeira rubicunda Keyserling, 1879 (by original designation).

Diagnosis (modified after Reiskind 1969). PER only slightly wider than AER, AER moderately recurved, PER moderately to slightly procurved; eyes approximately equal but often with AME larger than ALE; thoracic groove usually present, often strong; carapace index of 54–76; cephalic region moderately narrow (cephalic index 47–73); abdomen with negligible petiole; trochanter IV notch often present and deep ( Rubio et al. 2015).

Remarks. We do not include characters in our diagnosis that are provided for African ( Haddad 2012) or Asian species ( Deeleman-Reinhold 2001) of Castianeira that have not been tested on large series of Neotropical specimens. These include the shape of the labium, dorsal sclerite and male palpal cymbium, or the number of femoral spines, as these need to be confirmed for Neotropical species.
