Field characteristics:
Live adult female body oval, completely covered with felted grey ovisac.
Microscopic diagnosis:
Slide-mounted adult female body elongate oval. Antennae each with 7 segments. Frontal lobe present, frontal tubercle absent. Legs robust; hind coxa and femur with spinulae on anterior surfaces; hind coxa with large group of translucent pores; tibia with 5 setae elongate, not enlarged; tarsus longer than tibia; tarsal and claw digitules longer than claw, slightly knobbed; claw with a denticle. Anal lobes prominent, each lobe with 3 hair-like setae on dorsum, venter with 2 slender hair-like setae and a suranal seta, apical seta normal and elongate. Anal ring with a partial double row of pores and bearing 8 setae. Cauda present.
Dorsum
with enlarged setae blunt or truncate, normally of 3 sizes: on most segments, each side with 2 or 3 larger setae and some smaller ones, together forming a marginal band, but on posterior most 3 abdominal segments, each side of each segment with enlarged setae forming 1 or 2 irregular rows. Macrotubular ducts present throughout. Microtubular ducts numerous.

with smallest size of enlarged setae in a sparse row along body margin and forming a sparse submarginal band. Labium wide; basal segment with 2 unequal pairs of setae, apical segment with 5 pairs of long setae and a pair of short apical setae. Macrotubular ducts of
