Female (from 33°59.33'N, 118°36.11'W): A, habitus with egg-sacs (dorsal); B, habitus (lateral); C, pedigers 4 and 5, and anterior part of genital double-somite (ventral); D, genital double-somite (dorsal).
Scale bars: 0.1 mm (A, B); 0.05 mm (C, D).

Nota : Cephalon bearing 2 dorsolateral conspicillae (large refractile lenses) and 1 median ventral conspicilla. Large red pigmented area in antetriormost region. Vestigial mouth and transverse cuticular structure, possibly labrum, present.
A1 6-segmented (armature formula : 6, 2, 4, 2, 4, and 7 plus 1 aesthetasc ; setae sparsely pinnae or naked). A2 and oral appendages absent.
Urosome 4-segmented.
4th pediger segment much smaller than 3rd pediger. Intercoxal plate well developed in P1 to P3, missing in P4. P1-P4 biramous, 3-segmented rami, except for P4. P5 bearing 1 small naked and 1 large pinnate terminalseta at each member.
Genital double-somite broader in anterior region and carrying 2 small setae representing P6 in area of egg sac attachment. Multiseriate egg sacs with eggs measuring 0.05 mm in diameter.
Anal somite long and slender, at least 4.8 times longer than broad, with concave lateral borders. Digestive tract and anus appear to be absent.
Caudal ramus 2.85 times longer than wide, bearing 6 pinnate setae and inner distal row of setules.
