Slide-mounted Characters. Adult female with 3 pairs of well-developed lobes, fourth lobes with lateral lobule represented by series of low points. Median lobes separated by space 0.3 times width of median lobes, with yoke, medial margin parallel sided one-third to one-half length of lobe then strongly divergent to apices, lateral margins diverging slightly, with 0-2 lateral notches, medial margins serrate with 6-12 notches; second lobes bilobed, smaller than median lobes; third lobes bilobed, usually slightly smaller than second lobes. Gland spine formula 1-1-1, with about 11 gland spines near each body margin anterior of fourth lobe area, medial lobes without gland spines between them. Macroducts on pygidium about same size, without duct between medial lobes; submedial ducts on segments 3 to 5, with 1 to 2 ducts each; submarginal ducts on segments 3 to 5, with 1 to 2 ducts each; marginal ducts on segments 5 to 7 with 1 to 2 ducts each. Perivulvar pores in 5 groups; approximately 39 pores on each side of body. Anterior spiracles with 5 to 7 pores, posterior spiracles with 2 to 3. Antennae each with 1 conspicuous seta. Body elongate, pale yellow, cephalothorax roundish expanded, abdominal segments narrow.
