| Macrotrachela brachysoma, whirling specimen. This morphotype differs in some respects to the morphotype of M. brachysoma here >>> |

 |
| Macrotrachela brachysoma, two aspects of the head, dorsal view. Focus plane on the lobes of the upper lip. The lower image shows the ventral side of the lobes, which is characteristic for M. brachysoma. Although this morphotype has the same characteristic ventral extensions of the lobes of the upper lip, the corona is wider (ratio: corona width vs. head width ≈ 128%) compared to the other morphotype of M. brachysoma (ratio: corona width vs. head width ≈ 90%) |
