El conocimiento de la diversidad faunística en la Comunidad de Madrid es extraordinariamente limitado y parcialmente enfocado a grupos zoológicos determinados. Otros grupos zoológicos como los insectos, con un gran número de especies conocidas, han sido poco o nada estudiados en la región. Esto hace que el primer paso, básico para el conocimiento de esa biodiversidad biológica, sea cono
A comparative study was made of the structures of the preantennal region of nine species of Damalinia Mjöberg, 1910 (Phthiraptera: Trichodectidae). Variability in the form of the head, ventral carina, pulvinus, mandibles, and labrum was observed by light and scanning electron microscopy. According to previous studies, the form of the head is possibly influenced by the density and texture of the hair of the host. The ventral carina, which maybe sharp or blunt, and the pulvinus, a membranous lobe, of these parasite species of different hosts, were studied. Photographs of the mandibles and labrum show a high variability according to species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
