Full conservation status analysis:
Psychotria antilahimenae is known from 11 specimen collections representing nine unique occurrences in perhumid evergreen forest. The Extent of Occurrence (EOO) of the species is 2,407 km2, within the limits for Endangered under IUCN Red List Criterion B1; and the Area of Occupancy (AOO) is 32 km2, also within the limits for Endangered under Criterion B2 (IUCN, 2012). One occurrence is within the well-protected Masoala National Park, two occurrences are within Nosy Mangabe Special Reserve, and the other six occurrences are in unprotected areas adjoining but distinctly outside Masoala National Park and Makira Natural Park. Forested areas without formal protection in the vicinity of Masoala National Park and Makira Natural Park are subject to degradation by small-scale slash and burn agriculture and mineral exploitation (Goodman et al., 2018). Six “locations” (sensu IUCN, 2012, IUCN Standards and Petitions Committee, 2019) can be defined relative to the known threats: the one collection site within Masoala National Park; the two collection sites within Nosy Mangabe Special Reserve; the three collection sites near Ambanizana just west of Masoala National Park; and one location for each of the collection sites to the northeast and northwest of Masoala National Park and near the east edge of Makira Natural Park. With six locations, given general habitat degradation in unprotected sites and with no reason to assume that any of the unprotected sites is more likely to disappear than the others, the Red List status of Psychotria antilahimenae is assessed as VU B1ab(iii)+2ab(iii).
