Character

Metascutellum (=dorsellum) anterior extent [72]

Description

This and character 122 assess the relative size of the metascutellum (Krogmann and Vilhelmsen, 2006). The metascutellum is a differentiated dorsomedial region of the metanotum. The anterior margin of the metanotum has an edge, generally indicated by a rim, that the metascutellum may or may not extend to. This character could not be assessed externally in Metapelma (Eupelmidae) because the metascutellum protrudes as a flange under the apex of the protuberant scutellum. The posterior, convex part does not reach the anterior margin of the metanotum under the scutellum, and was scored as state 1. Citation: Krogmann & Vilhelmsen (2006: 108).
