FIGURE 1. Lateral profiles of queen mesosoma, showing two categories of mesosoma shape. A. "Normal" queen with narrow, vertically oriented propodeum. B. “acuta-group” queen with broader, more obliquely sloping propodeum. Degree of propodeal slope is measured as the difference from perpendicular for a line drawn from the propodeal suture to the posterolateral propodeal lobe, when mesonotum and scutellum are roughly horizontal. Degree ranges are for 20 species with normal queens and seven acuta-group species.
