Diagnosis
Hemicriconemoidinae.  Female elongate-cyclindrical, with double cuticle; outer one sheath-like, attached to body at head, vulva and sometimes at tail tip; annules of sheath and body round and flat, or rarely retrorse (H. minor); lacking scales, spines or other appendages; 50 - 158 in number, with or without lateral grooves.  Female cephalic region with two, rarely three annules, continuous or offset, variable in shape.  Pseudolips inconspicuous, submedian lobes absent, rarely present (H. coronatus).  Stylet elongate, with anteriorly cupped knobs appearing anchor-shaped (rarely speroidal). Vulva open or closed, with or without lateral cuticular flaps.  Female tail variable, bluntly rounded to pointed.  Males usually with four incisures in lateral field, cephalic region rounded or conoid-rounded, tail conoid to subcylindroid and bursa, when present, low subterminal or terminal (absent in type species).  Spicules setose, arcuate.  Gubernaculum simple, small.  Juveniles with single cuticle, with smooth, dentate or spined scales, arranged in longitudinal, usually alternating rows, or irregularly on body; rarely without scales or spines (H. minor, H. coronatus); stylet knobs anchor-shaped.
(Description- Siddiqi, 2000)

Criconematinae.
Female: Animal of small to medium size (0.29-0.67 mm). Body plump, straight or slightly ventrally curved, tapering on short distance at both ends. Number of annuli 51-164. Cuticle with two detached layers, closely adpressed; annulation strong, not retrorse; lateral field not marked. Vulva posterior. Vulval lips plain; vulval flaps occasionally present. Tail short, conoid to rounded. Labial framework heavily sclerotized. First anterior annuli not or weakly differentiated. No submedian lobes. Amphidial aperture slit-like. Stylet strong; basal knobs forward directed, generally with a jointed anterior process; rarely rounded; never sloping backwards.

 Male: Slender; oesophagus degenerated; stylet absent. Spicules slender, slightly curved; gubernaculum short and plain. Caudal alae rarely present, if so, weakly developed. Penial tube rarely present, if so, short.

Juveniles: One-layered cuticle; submedian lobes sometimes present, weakly developed; strong annulation; each annulus bears six, ten, or twelve scales conoid or provided with short denticles; when six on an annulus, alternate with the following annulus (twelve rows).
