Justification of Red List category
This poorly known species has a small range and its habitat is inferred to be experiencing continuing degradation. For this reason it is listed as Near Threatened.
Population justification
This species's status is difficult to determine because of its shy and retiring nature (del Hoyo et al. 2006), and is much rarer than M. whitneyi (G. Dutson in litt. 2016). It is unlikely that there are fewer than 1,000 mature individuals, but the population size may approach this number and so it is provisionally placed in the range of 1,000-2,000 mature individuals.
Trend justification
This species is suspected to be declining because of degradation of habitat, indicated by remote sensing data (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein) indicating localised forest loss and reports of an altered understorey comprising potentially exotic species (F. Lambert in litt. 2019).
Megalurulus turipavae is endemic to the mountains of Guadalcanal in the Solomon Islands. On Guadalcanal, it is only known from three records at the type locality at 1,200-1,550 m (Galbraith and Galbraith 1962, Gibbs 1996, G. Dutson pers. obs. 1997-1998) but is likely to be more widespread (Dutson 2011).
It occurs at 1,200-1,550 m in forest with both dense bamboo undergrowth and sparse undergrowth on Guadalcanal (Dutson 2011).
As a terrestrial species, it may be threatened by feral cats on montane Guadalcanal (Leary 1991). Climate change may be a significant threat in the future.
