FIGURE 10 in Observations on the terrestrial leech Haemopis septagon Sawyer & Shelley, 1976 (Annelida: Hirudinea) from the Outer Banks, North Carolina, USA, with a revision of the species
FIGURE 10. Haemopis septagon Sawyer & Shelley, 1976. Map of locality records. Haemopis septagon is currently known from the mid-Atlantic coastal plain from South Carolina to southern New Jersey. Scale bar: 100 km. See APPENDIX for compilation of locality records.
FIGURE 8 in Observations on the terrestrial leech Haemopis septagon Sawyer & Shelley, 1976 (Annelida: Hirudinea) from the Outer Banks, North Carolina, USA, with a revision of the species
FIGURE 8. Haemopis septagon Sawyer & Shelley, 1976. Dissected juvenile specimen from Albemarle Peninsula, North Carolina (HS-5) showing the mid-body crop is compartmentalized by sphincter-like muscle bands. Inset: schematic enlargement of consecutive segments XV and XVI, respectively, displaying anterior and posterior crop caeca per segment. Arrow indicates posterior position of pharynx (at segment XI). acc XV, anterior crop caecum of segment XV; c, crop; eb, ejaculatory bulb; gXVI, ganglion of segment XVI; mb, muscle band; n, nephridium of segment XVI; p, pharynx; pr, prostate; ps, penis sheath. Scale bar: 1.0 mm.
FIGURE 7 in Observations on the terrestrial leech Haemopis septagon Sawyer & Shelley, 1976 (Annelida: Hirudinea) from the Outer Banks, North Carolina, USA, with a revision of the species
FIGURE 7. Haemopis septagon Sawyer & Shelley, 1976. Reproductive system of Haemopis septagon from the Albemarle Peninsula, North Carolina. Comparison of the reproductive structures of A. terrestrial individual (HS-4), B. "aquatic" individual (HS-3), and C. juvenile individual (HS-5). For clarity the intertwining male and female ducts are separated and drawn semischematically to same relative scale. Note as the individuals mature the penis sheath and vaginal stalk extend progressively to the posterior, coupled with increased twisting of these structures. The simplest condition is found in the juvenile. In this species precise location of the point of flexion of the penis sheath and vaginal stalk is not species specific per se and therefore is of little taxonomic significance. e, epididymis; eb, ejaculatory bulb; ed, ejaculatory duct; gXI, ganglion of segment XI; gXV, ganglion of segment XV; gXIV, ganglion of segment XIV; o, ovisac; od, common oviduct; pr, prostate; ps, penis sheath; vc, vaginal caecum; vs, vaginal stalk.

FIGURE 4 in Observations on the terrestrial leech Haemopis septagon Sawyer & Shelley, 1976 (Annelida: Hirudinea) from the Outer Banks, North Carolina, USA, with a revision of the species
FIGURE 4. Haemopis septagon Sawyer & Shelley, 1976. Digestive tract of specimens from the Albemarle Peninsula, North Carolina. Comparison of the guts. A. Terrestrial individual (HS-4). B. "Aquatic" individual (HS-3). C. Juvenile individual (HS- 5). Of taxonomic significance, the pharynx in each case is prominently wide in relation to the crop, and extends posteriorly to ganglion XI (arrow), a unique feature among mid-Atlantic Hirudinidae. Furthermore, in each case the intestine consists of anterior and posterior regions, respectively (see text). Note the crop of the juvenile is segmentally compartmentalized and displays distinct anterior and posterior crop caeca per segment, a feature almost non-existent in adults (see also Fig. 8). acc XV, anterior crop caecum of segment XV; ai, anterior intestine; c, crop; gXIII, ganglion of segment XIII; gXIX, ganglion of segment XIX; p, pharynx; pcc XV, posterior crop caecum of segment XV; pcc XIX, posterior crop caecum of segment XIX; pi, posterior intestine; r, rectum.

FIGURE 3 in Observations on the terrestrial leech Haemopis septagon Sawyer & Shelley, 1976 (Annelida: Hirudinea) from the Outer Banks, North Carolina, USA, with a revision of the species
FIGURE 3. Haemopis septagon Sawyer & Shelley, 1976. Taxonomically significant caudal annulation. As shown in this individual (HS-7) segment XXIV bears 5 annuli, with the result that this species has 16 complete (5-annulate) segments (IX–XXIV, inclusively). All other hirudinid species from the mid-Atlantic coastal plain have the more usual 15 complete segments, i.e. segment XXIV bears only 4 annuli. A. Dorsal. B. Ventral. Scale bar: 2.0 mm.
