Type material. Ex P. g. goiavier, holotype male, Siaton, Negros Oriental, PHILIP­ PINES, 6 Feb. 1965, H. E. McClure, 5E­1755. Paratypes, all ex P. g. goiavier in PHILIP­ PINES: 1 male, 3 females, same as holotype; 1 male, 2 females, same except 18 Feb.–2 Mar. 1965, 5 E­1771, 5E­2081; 1 male, 1 female, Calatagan, Batangas, Luzon, 16 Sept. 1964, H. E. McClure, 5E­136, 5E­1599; 1 male, 1 female, Balian, Pangil, Laguna, 4 Nov. 1964, 5E­105.

Remarks. Both sexes of this species are very close to M. pycnonoti . However, the different structure of the male genital sac sclerite and the consistently longer inner tergal VII setae for the female will separate them. The hosts involved are all of northern and central Philippine origin, setting them geographically apart from all hosts for M. pycnonoti .

Etymology. This species is named for Chris Phillips, Illinois Natural History Survey, Champaign, in recognition of his encouragement and support for the publication of our world checklist of chewing lice.
