Description (from Thorne, 1974)
    Body forming an open "C" when relaxed, tapering both ways from near middle.  Lateral field 1/3 body width.  Lip region very angular, set off by deep constriction, with prominent papillae.  Spear about 11 um long with aperture occupying about 1/4 its length.  Guiding ring very narrow, about 1/2 head width.  Spear extensions joining esophageal lumen near middle of a conspicuous muscular bulb.  Esophagus a clear, slender tube, then expanded in basal 2/5.  Cardia discoid, then elongate conoid.  Intestinal cells filled with unusually large, dark brown, refractive granules.  Vulva longitudinal, without sclerotized labia.  Ovaries reflexed about 1/2 distance back to vulva.  An egg was 18x60 um.  Prerectum about 1 1/2 times body width.  Tail arcuate to subacute terminus.  No sperms present in gravid females and males probably are absent.
    Microdorylaimus angleus is distinctive because of its small size, very angular lip region, conspicuous bulb surrounding junction of spear extensions and esophageal lumen, and elongate-conoid, sub-acute tail.
    Habitat: Hillside thicket west of Wilmot, South Dakota.
