Figures

FIGURE 1. Benedeniella macrocolpa (Lühe, 1906) Yamaguti, 1963. Whole adult parasite, composite drawing, in ventral view based on AHC 29906 (specimen labeled no. 1) with some additions by hand. For clarity, extent of intestinal diverticula (entirely coextensive with the vitellarium) other than immediately posterior to pharynx and separate uterus parallel with terminal male genital duct are not shown and extensive convolutions of vas deferens are simplified (but are shown in full in Figure 6). Abbreviations: aao, anterior attachment organ; ah, anterior hamulus; as, accessory sclerite; c, cirrus; cp, common genital pore; cs, cirrus sac; dh, dorsal horn; e, excretory bladder; em, extrinsic muscle; g, germarium; gr, ventral groove; h, haptor; ho, hooklet; i, intestine; mv, marginal valve; n, longitudinal nerve trunk; o, ootype; p, pharynx; ph, posterior hamulus; rp, rounded papilla; t, testis; te, tendon; v, vagina; vi, vitelline follicle; vp, vaginal pore. Scale bar: 1 mm.

FIGURE 6. Benedeniella macrocolpa (Lühe, 1906) Yamaguti, 1963. Anterolateral region of body (left side) of adult parasite. Composite drawing in ventral view based on AHC 29905 (specimen labeled no. 1) with some additions by hand. Note that positions of some ducts (e. g. transverse vitelline duct, vas deferens and uterus) are displaced slightly for clarity. Also, common genital papilla, common genital pore, excretory papilla and vaginal pore are located dorsally and are shown here as seen by transparency. Abbreviations: cgp, common genital papilla; cv, common vitelline duct; dv, distal part of vagina; ep, excretory papilla; ey, eye; fc, fertilisation chamber; ju, junction of uterus and terminal male genital duct; m, male accessory gland reservoir; mg, terminal male genital duct; og, ootype glands; ov, oviduct; ovo, ovovitelline duct; pv, proximal part of vagina; tvd, transverse vitelline duct; u, uterus; vd, vas deferens; vdc, vas deferens within cirrus sac; vr, vitelline reservoir. Other abbreviations as for Figure 1. Scale bar: 1 mm.

FIGURE 8. Benedeniella posterocolpa (Hargis, 1955) Yamaguti, 1963. Whole adult parasite, composite drawing, in ventral view based on AHC 29911 (specimen labeled no. 4) with some additions by hand. For clarity, intestinal diverticula (entirely coextensive with the vitellarium) other than immediately posterior to pharynx and full extent of convolutions of vas deferens are simplified (but are shown in full in Figure 10). Abbreviations as for Figures 1 and 6. Scale bar: 1 mm.

FIGURE 10. Benedeniella posterocolpa (Hargis, 1955) Yamaguti, 1963. Anterolateral region of body (left side) of adult parasite. Composite drawing in ventral view based on AHC 29911 (specimen labeled no. 3) with some additions by hand. Note that positions of some ducts (e. g. transverse vitelline duct, vas deferens and uterus) are displaced slightly for clarity. Also, common genital pore, excretory papilla and vaginal pore open dorsally and are shown here as seen by transparency. Details of junction of oviduct, common vitelline duct and ovo-vitelline duct (all these structures are dorsal to the transverse vitelline duct) are shown in Figure 11. Abbreviation: ve, vas efferens. Other abbreviations as for Figures 1 and 6. Scale bar: 1 mm.
