Figure 5. Dendrorhynchus zhanjiangensis Yin & Zeng, 1984, a series of schematic transverse sections through different regions of the holotype of D. zhanjiangensis; the blood system is indicated by solid black. (A) In front of the proboscis pore. (B, C) Through the rhynchodaeal region. (D) At position of proboscis insertion, arrows point to the crescent-like lacunae. (E)–(G) Through successive positions of cerebral region. (H) At anterior border of mouth region; arrows point to the branches of ''esophageal blood lacuna''. (I) Through foregut region. (J) Through the anterior portion of intestinal region. (K) Through the position near posterior end of body.
