Paratypes, all ex P. urostictus in PHILIPPINES: 3 males, 1 female, same as holotype; 4 males, 3 females, same except 23 Apr. 1965, 5E­2189; 2 males, Balintad, Monai, Mindanao, 7–8 May 1965, 5 E­2092, 5E­2187; 1 male, Mt.

Remarks. The male of M. adamsae is unique by the shape of its genital sac sclerite coupled with the presence of 7–9 setae on sternite VIII. In addition, both sexes generally have more tergal and sternal setae, as well as a quite short inner seta on tergite VII.

Etymology. This species is named for Nancy E. Adams, Washington, D.C., in appreciation of her continuing generous help in lending us valuable louse specimens from the National Museum of Natural History collection.
