Two new species of sucking lice (Phthiraptera: Anoplura), Hoplopleura granti n. sp. (Hoplopleuridae) and Polyplax megacephalus n. sp. (Polyplacidae), are described from Grant's rock mouse, Micaelamys granti (Wroughton), from Northern Cape Province, South Africa. Adults of both sexes are illustrated via line drawings and differential interference contrast microscopy images, and are compared with previously described related species that parasitize related hosts: Hoplopleura patersoni Johnson from Aethomys chrysophilus (de Winton) (red veld rat), Aethomys kaiseri (Noack) (Kaiser's aethomys), and Micaelamys namaquensis (A. Smith) (Namaqua rock mouse); Hoplopleura aethomydis Kleynhans from M. namaquensis; Polyplax praomydis Bedford from A. chrysophilus and M. namaquensis; and Polyplax solivaga Johnson from A. chrysophilus. It is not known if these new species of lice are vectors of any pathogens.

吸虱（Phthiraptera：Anoplura）的两个新种，Hoplopleura granti n。sp。（Hoplopleuridae）和巨头Poly（Polyplax megacephalus）。sp。（Polyplacidae），描述于来自南非北开普省的格兰特（Grant）的岩鼠Micaelamys Granti（Wroughton）。通过线条画和差分干涉对比显微镜图像说明了两性的成年，并与先前描述的寄生相关寄主的相关物种进行了比较：Aethomys chrysophilus（de Winton）的Hoplopleura patersoni Johnson （红Johnson鼠），Aethomys kaiseri（Noack） （Kaiser的aethomys）和Micaelamys namaquensis（A. Smith）（Namaqua摇滚老鼠）；Hoplopleura aethomydis从Kleynhans M. namaquensis ; Polyplax praomydis从贝德福德A. chrysophilus和M. namaquensis ; 和Polyplax solivaga约翰逊A. chrysophilus。这些虱子的新物种是否是任何病原体的载体，这一点尚不清楚。
