The fore wings: Male. Length forewing/wingspan 56-58/94-96 mm. Forewing upperside and underside black, grey on both sides of the veins, filling almost half of the wing. H 


The hind wings:  Hindwing crenulate; upperside and underside black, white area in outer third, black area along margin may be divided into large rounded spots, small black spots in spaces 2-4; large anal fold white on upperside with pinkish outer border. 

The body:  

Sex differences: Female. Length forewing/wingspan 67-68/101-104 mm. Similar to male, but lacking the widened anal fold of the hindwing.

Variation and infraspecific taxa: Too gfew specimens known to give an impression of the variation.

Similar species: Rather similar to the largerĀ  A. priapus, but can be distinguished bya red band on both sides of thorax and abdomen.

Habitat: Forest - Subtropical/Tropical Moist Lowland,Forest - Subtropical/Tropical Moist Montane
The foodplant(s) of this species are not known. It is likely that its hostplant belongs to the family Aristolochiaceae. The Ijen mountain range is volcanic, with the highest point on the Raung volcano, at an elevation of 3,332 m (Collins and Morris 1985). There are frequent eruptions of volcanoes within the range, for example the eruption of Mount Merapi in May 2018 (Damiana 2018). The Ijen mountain range is the least populated part of Java and large areas of forest (that mainly cover the mountains) remained intact and undeveloped when the species was assessed in 1985 (Collins and Morris 1985). There are also many high plateaus, lakes and craters in the mountain range (Collins and Morris 1985). This species is likely to occur at a medium to high altitude as this is where the most suitable, undeveloped land is found. There are some forested tracts here too which is where the species is likely to be found.

Population: The exact population of this species is unknown, but only a few specimens had been recorded by 1982 and it is only found in a very restricted area; it is therefore likely that the population is small (Tsukada and Nishiyama 1982). As a result of its restricted range, the species was assessed as Vulnerable in a status assessment in 1996 (Gimenez Dixon 1996). There are no recent population data available for this species.
Range: This species has a very restricted range in the Ijen mountains of eastern Java (Collins and Morris 1985). Its estimated extent of occurrence, based on the area of the Ijen mountains, is estimated between 1,000 and 2,000 km2, although it may be much smaller, given that only few locality data exist for this species.
