Key to the species of Anomiopsoides

Anomiopsoides species show considerable intraspecific variation due to particular conditions during an individual’s development, environmental conditions of the area in which the specimen lived, and/or age of the specimen at the time it was collected. The above factors make identifications difficult for some Anomiopsoides specimens, particularly females.

1. Medial processes of clypeus with external margin broadly rounded or lobed and medial margin concave or straight ( Figure 2b, e ).......... 2

– Medial processes of clypeus with external margin straight, slightly rounded or sinuous and medial margin straight or rounded ( Figure 2a, c, d, f, g ).... 3

2. Medial processes of clypeus with external margin lobed ( Figure 2e ). Mesotibial external spur wider on apical third ( Figure 3a )....................... A. biloba (Burmeister) (male and female)

– Clypeus with medial processes with medial margin broadly rounded (but not lobed) ( Figure 2c ). Mesotibial external spur simple, not or slightly wider on apical third ( Figure 3b )..... A. catamarcae Martínez (male, female unknown)

3. Clypeal disc with large, deep fovea before and between medial processes... 4

– Clypeal disc without foveae before medial processes......... 5

4. Clypeus with medial processes long (longer than rest of head), with apex divergent ( Figure 2c )............ A. cavifrons (Burmeister) (male)

– Clypeus with medial processes short (shorter or as long as rest of head), with apex pointed ( Figure 2d )........ A. cavifrons (Burmeister) (female)

5. Clypeus with medial processes long (longer than rest of head), with apex divergent ( Figure 2f )........... A. heteroclyta (Blanchard) (male)

– Clypeus with medial processes short (shorter or as long as the length of frons plus length of clypeal disc), with apex pointed ( Figure 2a, g )........ 6

6. Clypeal surface not perpendicular in frontal view between clypeal medial processes ( Figure 2g )........... A. heteroclyta (Blanchard) (female)

– Clypeal surface perpendicular in frontal view between clypeal medial processes ( Figure 2a )......... A. aurita (Burmeister) (male and female)
