4. Stichophthalma suffusa tonkiniana (The Jungle Queen s.l.)

Number: 4

Family: Nymphaliidae
Sub-Family: Amathusiinae

Species: Stichophthalma suffusa tonkiniana Leech, 1892

Common name(s): The Jungle Queen (sensu lato)

Photography location: Tam Dao (Vinh Phuc Prov.)

According to Monastyrskii & Devyatkin (2016), the subfamily Amathusiinae is represented in Vietnam by 10 genera: Faunis (5 species), Aemona (7 species), Stichophtalma (8 species), Amathusia (1 species), Amathuxidia (1 species), Zeuxidia (2 species), Thaumantis (1 species), Thauria (1 species), Discophora (4 species), Enispe (3 species).

Stichophthalma howqua suffusa has been raised to species S. suffusa Leech, 1892 (Monastyrskii & Devyatkin, 2008). S. suffusa tonkiniana has an ocre-yellow ground color on the Up of both wings with completely fused submarginal black markings on the UpH.
At Tam Dao, in northern Vietnam, this species occupies both primary and secondary forest habitats, at all elevations.

Stichophthalma suffusa tonkiniana feeding on rotten fruits (rocks along a stream, Tam Dao, 200m asl) This specimen was at a well-lighted place, a rare opportunity to take photo without flash
This specimen is very likely a female (Un with whitish discal band, located behind the subbasal area which is margined by black zigzag lines)

Another specimen, resting on leaf in dense forest (Tam Dao, 900m asl), showing faint ocelli
Very likely a male (Un with brownish orange tinge, discal band pale brown)

This is a cryptic species, with underwings resembling dead leaves. When resting on vegetation, Stichophthalma species close their wings. When flying, they slowly glide in a zigzag course within the dark vegetation, resembling falling leaves. Never seen visiting flowers. The only observed source of food was tree sap, rotting fruits and birds droppings.
