|Population:||Although it is known from only 3 specimens, it likely to be more widespread than these records would indicate.|
|Habitat and Ecology:||This species has been found in dense cane on a riverbank (Jones and Engstrom 1986), and in a banana plantation on very wet, red clay (Thomas 1905). Its biology is poorly known; it is possibly semiaquatic (Reid 1997).|
|Major Threat(s):||There are no known threats to this species.|
|Conservation Actions:||Very little is known about this species. Further research needs include taxonomic and ecological studies.|
