Female. — Head completely fused with the first segment, the forehead flattened so that the corneal lenses appear in profile in dorsal view; second, third, and fourth segments fused dor- sally and concealing the fifth segment, so that the metasome appears 2-segmented in dorsal view. Lappets on the third seg- ment acuminate and reaching beyond the center of the uro- some; no lappets on fourth segment. The 1-segmented urosome widest near the front; caudal rami half as long as urosome, four times as long as wide. Total length, mm.
