Excretory pore level with center of median bulb.
Basal esophageal bulb elongate-pyriform. Not overlapping
to slight ventral overlap of intestine.
Vulva a transverse slit in an oval depression which
has anterior and posterior pouches that appear to be sclerotized.
Cuticle on ventral surface anterior and posterior to vulva with up to
10 deep groovesseparated by two or three annules. (miradvulvus =
unusual near vulva).
Interior of vagina with strengthening ridges.
Ovaries paired, outstretched, spermathecae present.

and gubernaculum slightly arcuate. Gubernaculum with reflexed distal

Recorded soil and plant samples of Anubias nana Engler from a
commercial aquarium plant nursery in Florida. Can be cultured on Zea mays.
Causes damage to Anubias nana.
Ectoparasite mainly at root tip; nematode has long stylet.
Feeding of D. miradvulvus at root initials of the
aquatic plant Anubias nana can result in complete destruction of the
root system (Smart and Khuong, 1984, 1985; Smart and Nguyen, 1991).
