PhylomeDB has been recently expanded with the incorporation of eight new arthropoda species. This is part of our current efforts to coordinate our analysis with those of other annotation platforms. In this case, this is a joint effort with ArthropodaCyc, and the eight new arthropod phylomes have been used to help re-annotatating metabolic networks in these species. The new species are the three mosquitos Culex quinquefasciatus, Aedes aegypti, and Anopheles gambiae, the honey bee Apis melifera, the wasp Nasonia vitripennis the tick Ixodes scapularis, the body louse Pediculus humanus, and the water flea Daphnia pulex.

These species add to the otehr 14 species with a phylome in phylomeDB including the 12 sequenced Drosophila species, the beetle Tribolieum castaneum and the pea aphid Acyrtosiphon pisum. Thus, with 22 seed species, phylomeDB constitutes the major phylogenetic repository for arthropoda. PhylomeDB participates in the i5K initiative, which promotes the sequencing of 5,000 arthropod genomes. We offer PhylomeDB resources, including the reconstruction of phylomes for newly-sequenced species to groups participating in such initiative.
