▲Dichorragia nesimachus pelurius(C. Sulawesi, Indoneia)
[preserved in RIEB, Tokyo]
Continued to the previous post, the Constable (Genus Dichorragia) and its allies are introduced. First of all, Dichorragia nesimachus has many sub-species especially in southeastern Asian Islands. One of the examples is shown above. This is the subspecies endemic to Sulawesi, Indonesia. It is much larger in size and the pointed apex in forewings is quite different from Japanese subspecies.
▲Stibochiona nicea (Yunnan, China)
[preserved in RIEB, Tokyo]
▲Stibochiona coresia (Sumatra, Indonesia)
[preserved in RIEB, Tokyo]
The above two species belong to Genus Stibochiona. This small Genus contains three species from India to southeastern Asian islands. Among them, Stibochiona nicea is confined to continental Asia from India to China including Indochina and Malaysia. Another species, Stibochiona coresia is known from Sumatra and Java in Indonesia. Both species seem to be allied species of Dichorragia nesimachus from thier wing markings.
▲Amnosia decora (Sumatra, Indonesia)
[preserved in RIEB, Tokyo]
▲Ditto, Underside
On the other hand, there is a very interesting species in Malaysia and Indonesia. Amnosia decora seems to belong to Amathusiinae or Satyrinae at a glance. But this species is definitely the allied species of Dichorragia nesimachus, considering its early stages. Amnosia is monotypic genus, this species is known from Malay Peninsula to Sumatra or Java.
