Once only known from the holotype, a single specimen collected from North Sumatra in 1891, the species was rediscovered after a living population of the species was sighted in 2018.^[3]

Etymology

The specific name, modiglianii, is honor of Italian botanist Elio Modigliani.^[4]

Geographic range

H. modiglianii is indigenous to northern Sumatra, Indonesia.^[1][2]

Habitat

The preferred natural habitat of H. modiglianii is forest.^[4]

Description

The holotype specimen is a male, and the preservation process had caused it to turn blue. The discovery of live specimens in 2018 revealed that the species is naturally a luminous green colour in life.^[3]

H. modiglianii has a sickle-shaped upturned nasal appendage. Not including this appendage, the holotype has a snout-to-vent length (SVL) of 8.3 cm (3.3 in), and a tail length of 13.9 cm (5.5 in). Its nasal appendage is 6 mm (0.24 in) long, roughly as long as the head.^[5]

Reproduction

H. modiglianii is oviparous.^[2]
