3D-reconstruction of the head structures of a female Philanthus barbiger. The upper reservoir of the PPG (orange) is located in front of the brain (light grey) and extends laterally towards the compound eyes (grey), the sac-like lower reservoir of the gland (red) originates ventrally from the pharynx (black). The small MG reservoirs (blue) are located laterally on both sides of the head capsule, opening at the mandibular base. Abbreviations: ant, antenna; br, brain; ce, compound eye; lo, lower part of PPG; md, mandibles; mg, mandibular gland reservoir; oc, ocelli; ph, pharynx; up, upper part of PPG. Scale bar = 0.5 mm
