Abstract
We report the identification of genomic sequences in various anopheline mosquitoes (family Culicidae: suborder Nematocera: order Diptera) showing homology to the class II, short inverted-terminal-repeat (ITR) transposable element P from Drosophila melanogaster (family Drosophilidae; suborder Brachycera: order Diptera). Anopheles gambiae appears to have at least six distinct P elements. Other anopheline species, including four additional members of the An. gambiae species complex (An. arabiensis, An. merus, An. melas and An. quadriannulatus), Anopheles stephensi (all subgenus Cellia), An. quadrimaculatus (subgenus Anopheles) and Anopheles albimanus (subgenus Nyssorhynchus) also possess P elements similar to those found in An. gambiae. Ten distinct P element types were identified in the genus Anopheles. At least two of the An. gambiae elements appears to be intact and potentially functional. Phylogenetic analysis of the anopheline P elements reveals them to belong to a distinctly different clade from the brachyceran P elements.
