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.
