title: Six new species of Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from New World jays of the genus Cyanocorax Boie (Passeriformes: Corvidae), with notes on the chorionic structure of eggs.
abstract: The only species of previously named Myrsidea Waterston, 1915 from Neotropical jays of the genus Cyanocorax Boie (Passeriformes: Corvidae), Myrsidea fallax Kéler, 1938 (type-host Cyanocorax cyanomelas Vieillot), is redescribed and six new species of lice in the genus Myrsidea are described: Myrsidea pseudofallax n. sp. [type-host C. c. chrysops (Vieillot)]; M. moriona n. sp. [type-host C. m. morio (Wagler)]; Myrsidea daleclaytoni n. sp. [type-host C. v. violaceus Du Bus de Gisignies]; Myrsidea lindolphoi n. sp. [type-host C. caeruleus (Vieillot)]; Myrsidea melanocyanei n. sp. [type-host C. melanocyaneus chavezi (Miller & Griscom)]; and Myrsidea cristatelli n. sp. [type-host C. cristatellus (Temminck)]. A key to the identification of both sexes of these seven species is provided. Immature stages of M. daleclaytoni n. sp. (all instars) and M. cristatelli n. sp. (nymph III) are described. External chorionic architecture of the eggs is described and illustrated for six Myrsidea spp. from corvine birds: M. picae (Linnaeus, 1758) ex Pica p. pica L.; M. cornicis (DeGeer, 1778) ex Corvus c. corone L.; M. isostoma (Nitzsch in Giebel, 1866) ex Co. f. frugilegus L.; M. interrupta (Osborn, 1896) ex Co. brachyrhynchus Brehm; M. fallax ex Cy. cyanomelas; and M. moriona n. sp. ex Cy. m. morio. This is the first review of the data on Myrsidea spp. infesting Neotropical Corvidae.
