Habitat : Trinidad, on the banks of streams, under stones, and in the 

 woods, under the leaves in damp places. 



This small species is distinguished by the bright, but somewhat chan- 

 ging colouration and marking with grayish white, blackish gray and 

 carmine red. Among the Hylodes species with a granular belly and with 

 vomerine teeth, situated in small groups behind the chaonae, it is very 

 much like H. ccrasinus, Cope, from Costa Rica, but nearly half the size, the 

 tongue broad oval, nearly round, the tympanum between i-3rdand J the 

 size of the eye, the fingers much shorter, and the disks broad oval, but not 

 truncate in front. H . whymperi, from Ecuador also shows a similar blood 

 red colour on the groin and on the hind limbs, but is otherwise entirely 

 different.
