Thalassodes
immissaria Walker
Thalassodes immissaria Walker,
1861, List Specimens lepid. Insects Colln Br. Mus. 22: 583.
Thalassodes immissaria intaminata Inoue,
1971, Bull. Fac. dom. Science, Otsuma Wom. Univ.
7:144.
Diagnosis. This species can be distinguished from
the previous one in the male genitalia by the large, tongue-like process that
extends dorsally from the region of the transtilla. The scobinate flap is
narrower and the arcuate ridge in the sacculus less pronounced than in depulsata.
The distal margin of the eighth sternite is less excavate centrally, with
short, acute processes flanking the excavation.
Taxonomic notes. There is some variation in the scobinate
flap (narrow in a specimen from Sumatra (slide 4114) and with a subbasal angle
in one from Sulawesi (slide 4161)). The concept is based on a specimen from Sri
Lanka (slide 3003) proposed by D.S. Fletcher (MS) as a possible Neotype for immissaria
(type probably lost).
Geographical range. Sri Lanka, Borneo, Sumatra, Sulawesi
(dissected material only - see above); Ryukyu Is. (ssp. intaminata). The species
is probably widespread in the Oriental tropics.
Habitat preference. The only Bornean specimen identified is
from Semengok, near Kuching in Sarawak (slide 8685).
Biology. There is material from India attributed
to immissaria in the Natural History Museum that was reared from Mangifera
(Anacardiaceae), Lagerstroemia (Lythraceae) and Nephelium (Sapindaceae).
