Figures 6–8 in New genera of melikertine bees with facial modifications in Baltic amber (Hymenoptera: Apidae)

Figures 6–8. Worker of Succinapis micheneri Engel (SEMC B-017). 6. Oblique facial view. 7. Outer (prolateral) view of metatibia and metabasitarsus. 8. Detail of fringe setae of metatibial posterior/upper margin; white arrow indicates a deceptive internal microfracture of resin trail with branched fractal patern (such fracture planes and trails are a common taphonomic structure among or even running alongside many fine setae in amber inclusions, and can give such setae an artificially plumose appearance; accordingly, care must be taken before concluding whether or not amber-included setae are branched); black arrow highlights one of many truly plumose setae, separate from the internal microfracture planes.
