Justification of Red List category
This formerly common species appears to have declined rapidly following a hurricane in 1988, with very few subsequent records, despite repeated surveys since then. A recent probabilistic assessment by Butchart et al. (2018) concluded that T. guttatum does not meet the threshold to be considered 'Possibly Extinct' and as such, despite only one unconfirmed sighting since 2004, the species likely remains extant. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered.
