Character Details

Character

Position of axilla [55]

Description

Coding this character is problematic because there are no clear positional landmarks that can be used across families. The size and position of the axillae impact features of the surrounding structures that correlate with several other characters in this matrix. This character has been used to help define Aphelinidae, Eulophidae, and Trichogrammatidae and to help define several pteromalid groups (Graham, 1969; Bouček, 1988a). The original concept was applied only to "strongly" advanced axillae, but intermediate structures led to our attempt to indicate axillar position more precisely. State 0 is distinguished from state 1 by having a very straight transscutal articulation with no anterior curvature laterally.
