Icerya jacobsoni group

We include five species in this group: I. assamensis , I. jacobsoni , I. jaihind , I. mangiferae and I. zimmermanni . Although the species vary in their egg-tending behaviour ( I. assamensis forms an internal marsupium, I. zimmermanni has an ovisac band and a simple waxy pad of secretion covering the ventral surface and I. jacobsoni , I. jaihind and I. mangiferae form neither an ovisac nor a marsupium), simple multilocular pores with characteristic stalked profiles are found on the dorsal surface of all species. Icerya jacobsoni and I. jaihind differ from one another by the number of ventral cicatrices ( I. jacobsoni has three and I. jaihind has a single cicatrix). We were unable to examine material of I. mangiferae , but we include it in this group based on the original description and because we believe it a likely synonym of I. jacobsoni . Refer to the taxonomic notes on I. mangiferae for further discussion.
