Fig. 1. (A–C) Definition of morphometric characters: (A) posterior part of mesosoma in lateral view; the sum of the angles α, β, γ, δ, ε is not necessarily 360◦ because these are angles in a three-dimensional tetrahedron described by SPST, PLSP, MPPL, MPST, MPSP, and PLST; (B) petiolar node in lateral view; (C) mesosoma in lateral view. For definition of morphometric characters see Section 3.4.
