Genus Bakernema
Wu, 1964
Diagnosis
Criconematinae. Female moderately large (0.5-0.55 mm), with transparent
spine-like appendages on head and body annules which are not easily seen
in glycerin-mounted specimens. These appendages are variable in width
and spacing on annules, form leaf-like flaps on tail tip, and are not arranged
in definite longitudinal rows over the body. Annules 65-70 in type
species, almost round. Cephalic region of two to three undifferentiated
annules, not set off; labial disc elevated. Pseudolips not well developed,
submedian lobes weakly developed; framework heavily sclerotized.
Stylet 64-70 um lonb, in type species not flexible. Vulva on fourth
to seventh annule from terminusl anterior lip annule strongly developed,
extending over it. Vagina sigmoid. VL/VB about 1; caudal end
conoid-rounded. Male cephalic region rounded, lateral field with
four incisures, bursa present, low, subterminal. Spiculues setose,
36-48 um long in type species. gubernaculum 6-7 um long. Hypoptygma
single. Juvenile annules apparently smooth or crenate, but possibly
with membranous spined outgrowths. Juveniles lack cuticular appendages
in type species.
