My information given under Cyclopeltis Persliana Berk, regards also 

 this species. The Buitenzorg specimens, as far as still provided with scales, 

 have the scales minutely, horizontally denticulate, the teeth split at the tip 

 into 2 horizontally spreading, decurvate-uncinate toothlets. as in D. cera- 

 lolepis Christ (Farnkr. d. Erde, 221, fig. 703).
