Ronquist: Although this term is primarily of use in the Apocrita, a homologous region is distinguishable in many sawflies. Miko: the axillar pit of Masner and Garcia is synonym of axillula. Bot the pit and the definition is incorrect, though (pit: point-like, has to corespond to interal apophysis; the pit is not on the axilla as in the definition of Masner and Garcia.

Lateral, usually more or less vertical subdivision of the scutellum differentiated from the rest of the scutellum by the axillular groove/carina or sublateral groove and from the axilla by the scutoscutellar suture.

Anterolateral region of the mesoscutellum. The axillula is the region between the lateral scutellar bar, or the fold between the lateral and dorsal surfaces of the mesoscutellum when the scutellar bar is absent, and the often raised anterolateral margin of the mesoscutellum. The axillula ends anteriorly in the scutoscutellar sulcus.
