Drawing from Luc et al., 1987 |
Neodolichodorus rostrulatus. Tails: A, B, 2nd stage juveniles;
C,D, 3rd stage juveniles; E, F, 4th stage juveniles; G, H, 1 :
females; J : Male tail, copulatory organs and musculature (ventral
view); K : Same as J (lateral view); L : Gubernaculum (lateral view); M
: Arrangement of spicules and gubernaculum at three different levels
(transverse sections). (muscles : v.r.sp = ventral retractor spiculi;
d.r.sp. = dorsal retractor spiculi; a.pr.sp. = anterior protractor
spiculi; p.pr.sp. = posterior protractor spiculi; sed.g. = seductor
gubemaculi; pr.gub. = protractor gubemacuii).

Females:
- Body elongated, cylindrical, tapering anteriorly, but not
posteriorly; with shallow ventral depression in the vulval
area,
- Posterior terminus subclavate, bluntly rounded. A
- Lateral field with four lines, external bands of lateral field
regularly crossed by body annules,
- Labial area high and expanded, flattened anteriorly, roughly
cushion-shaped, separated from rest of body by a deep
constriction.
- Stylet long and thin, basal knobs rounded, smooth
anteriorly, directed backward.
- Procorpus cylindrical to slightly barrel-shaped;
- DEGO 4-6 um from the base of the stylet;
- Median bulb strong, heavily muscular, about half of the
corresponding body diameter, ovate in profile, with strong valve;
- Basal bulb ovate
- Pharyngo-intestinal valve strong, roughly conoid-truncate.
- Excretory pore at about the level of isthmus
- Intestine overlapping rectum, filling nearly all the tail
volume; canals (= fasciculi) present.
- Vulva a transverse ellipse or oval without flaps, situated in a
depression of the cuticle
- Distal part of vagina with heavy sclerotization,
- Didelphic, amphidelphic, ovaries outstreched,,with well
developed axial sperm-filled spermathecae.
- Tai1 rounded;

Males:
- Body similar to that of female, but shorter
- Labial area less expanded than female.
- Spicules slightly ventrally curved, not cephalated, devoid
of a velum, distal end obtuse.
- Gubernaculum slightly protruding from cloaca,
- Tail short, pointed in lateral view.
- Caudal alae well developed, indented posteriorly; lateral wings
rounded, annulated, edges crenate; central part ending at same level
as lateral wings, with truncate or bifid extremity.
