Abstract. — YoxxTitQn species are described in the subgenus Cracimenopon Car-riker genus Amyrsidea Ewing from galliform hosts of the family Cracidae. One new species, A. (C) rogersi from Crax fasciolata, is described, and 13 new syn-onymies are given. Illustrations and a key for identification of the species are given. The menoponid genus Amyrsidea Ewing, 1927, has recently been revised to recognize five subgenera (Scharf and Price, 1977, 1983; Scharf and Emerson, 1983). The genus is distributed world-wide on galliform hosts. Each of the sub-genera has a discrete host group whose geographical distribution is distinctive. These subgeneric distributions are as follows: Amyrsidea from three genera of the Phasianidae from southeast Asia; Desumenopon Carriker from neotropical quail of the genus Odontophorus: Phasianidae; Argimenopon Eichler from four families of Phasianidae from Africa, India, southeast Asia, and the Holarctic Region; Numidimenopon Scharf from the family Numididae from Africa; and Cracimen-opon Carriker from the neotropical family Cracidae. Cracimenopon species are distinctive not only in being restricted to one family of hosts, but also because of their large prominent eyes, preocular slit usually deeper than 0.025 mm, lack of setae on stemite I, sexually dimorphic ventral pleural extensions and frequent enlargement of anterior terga in females. This paper presents descriptions, illustrations, and a key to the 14 species of the sub-genus Cracimenopon. In the following descriptions, numbers of certain head setae are those given by Clay (1969). Measurements are in millimeters. Unless noted, all illustrations are of specimens from the type-host. The nomenclature of the hosts follows Peters (1934), but some pertinent recent changes are given based on Delacour and Ama-don (1973) and Vaurie (1968). Subgenus Cracimenopon Carriker Cracimenopon Carriker, 1954: 21. Type-species: Cracimenopon mituensis Car-riker. The members of this subgenus form a group of closely related lice which are known only from the Cracidae. They may be separated from other subgenera by the following combination of characteristics:
