Hemicycliophora typica
de Man, 1921
Photo Gallery- Greece

Female : 1.2 mm; a = 20; b = 6.0; V 5284
 Body marked by 256-280 annules.  Larval cuticle fitting rather closely.  Lateral fields simple without longitudinal markings.  Lip region rounded with 2 annules in last larval cuticle, but none on lips proper.  Spear extending through 19-26 annules, the basal knobs projecting slightly backward.  Basal bulb of esophagus slightly clavate.  Excretory pore opposite beginning of intestine.  Hemizonid small but distinct, adjacent to excretory pore.  Intestinal cells vacuolated, containing small nuclei.  Ovary outstretched, about one-half as long as body.  Uterus with prominent spermatheca.  Vulva with protuberant posterior lip, located at a ventral contraction of the body.  Anus very obscure, 14-17 annules posterior to vulva.  Tail at first convex-conoid, then elongate conoid to the small sharp terminus.
 Male : 1.0 mm; a = 34; b = 6.2; c = 5.1; T 42
 Cuticle marked by fine but distinct striae.  Lateral fields with 3 lines forming 2 bands which extend from near the head to near the middle of tail.  Lip region slightly expanded.  Spear absent.  Pharynx sometimes appearing as an open chamber with slightly sclerotized walls.  Esophagus a slender tube with nerve ring near its base.  Excretory pore opposite base of esophagus.  Hemizonid very distinct, slightly anterior to excretory pore.  Intestinal cells vacuolated, with scattered granules.  Testis outstretched, slightly less than one-half body length.  Spicula semi-circular, as illustrated.  Bursa broad, about 3 times as long as body width.  Tail conoid to the small pointed terminus.
 DIAGNOSIS. Hemicycliophora typica is distinctive because of the tail form, the simple lateral fields and the semi-circular spicula.
