1.4 mm; a = 29; b = 3.6; c = 37; V = 60
Body slightly arcuate in posterior third. Lip region angular,
set off by constriction. Guiding ring sclerotized, refractive.
Spear 15u long with aperture 1/3 its length. Esophagus enlarged
by rather abrupt expansion near middle until 1/2 body width, gland nuclei
arranged as in Eudorylaimus. Cardia discoid, then elongate conoid
with intestinal cells surrounding it almost to apex. Intestinal lumen
frequently with green or red colored contents. Prerectum length about
equal to body diameter, a pouch-like dorsal extension usually extending
back over rectum. Tail dorsally convex-conoid to rounded terminus,
bearing two pairs of lateral pores. Ovaries reflexed about 1/2 their
length. Vulva transverse, at bottom of a small round depression.
Eggs about 40 to 75u, as many as 4 being observed at one time.
Male not collected and gravid females contained no sperms.
Eudorylaimus longicardius is immediately distinguished by the posterior
location of the vulva, intestinal cells surrounding the cardia and tail
