0.9-1.3 mm; a = 27-30; b = 6.5-7.0; c = 28-32; T = 42-50 
     Body slightly curved when relaxed.  Cuticle coarsely annulated with 4 incisures which usually are at least partly aerolated.  Lip region set off, with 4 annules divided into tile-like elements, about 40 being in the basal annule.  Cephalic framework massive, sometimes yellow.  Spear knobs with forward pointing processes.  Dorsal esophageal gland opening near spear base.  Median bulb spheroid.  Basal bulb extending in a lobe over intestine, usually dorsally.  Ovaries outstretched with spheroid spermatheca.  Intestine extending into tail with rectum attached to ventral side.
     Male smaller and more slender than female.  Lip region without tiling, or with only the basal annule divided. Spicula slightly arcuate.  Gubernaculum with titillae.  Bursa broad, striated, enveloping tail.
Hoplolaimus galeatus is generally distributed throughout the region, often in sufficient numbers to cause considerable damage to the roots of wheat and other plants. Feeding is both ectoparasitic and endoparasitic.
