lipotrophidae lipotrophidae the lipotrophidae are a family of parasitic alveolates in the phylum apicomplexa. species in this family infect insects (diptera, lepidoptera, coleoptera and hymenoptera). lipotrophidae scientific classification domain: eukaryota (unranked): sar (unranked): alveolata phylum: apicomplexa class: conoidasida subclass: gregarinasina order: neogregarinorida family: lipotrophidaegrassé 1953 genera apicystis farinocystis lipotropha lipocystis mattesia menzbieria history this family was created by grasse in 1953. taxonomy six genera are currently recognised in this family. lifecycle merogony generally occurs by budding from surface of meront to form uniformly sized merozoites. the gametes are similar (isogametes) and fuse to form navicular oocysts which have pronounced polar thickenings. the oocysts contain eight (rarely four) sporozoites.
