Makira (Solomon Isls)

CITES - Not Listed (2023). IUCN - Near Threatened (2020).

Previously considered a subgenus of Melonycteris (see e.g., Phillips, 1968; Flannery 1993; Simmons, 2005). Raised to full generic status by Almeida et al. (2020). Melonycteris, including Nesonycteris, was revised by Flannery (1993). Does not include maccoyi or mengermani; see Pulvers and Colgan (2006) and Lavery et al. (2023). See also Flannery (1995). Populations on Guadalcanal previously attributed to fardoulisi appear to belong to woodfordi; see Lavery et al. (2023). For phylogeography see Pulvers and Colgan (2006) and Lavery et al. (2023).
