There are 468 with Coordinators: 86% of families 85% of the estimated number of species are listed. Coordinators are still needed for: GROUP TOTAL Rhodacaroidea 750 Veigaiidae 100 Eviphidoidea 550 [250] Ameroseiidae 100 Dermanyssoidea 2000 [127] Eupodoidea 300 [150] Halacaroidea 1000 Trombidioidea 2500 [600] First figure is estimated total number of species in the group. Second figure indicates number of species for families that have Coordinators in group. I have approached specialists for the Halacaroidea and Trombidioidea to be Coordinator of the group/and or families in the group. Some small families are not included and a few medium size families of superfamilies that have a coordinator, have not had a Coordinator assigned. See the Family listing of Acari and look in the status column. An asterisk indicates a Coordinator exists for that family.
