Thalassodes
curiosa Swinhoe
Thalassodes curiosa Swinhoe,
1902, Trans. ent. Soc. Lond., 35: 673.
Thalassodes curiosa Swinhoe;
Holloway, 1976: 62.
Diagnosis. This is a rather translucent species, with rather irregular dentate
fasciae appearing darker than the ground colour, perhaps representing a more
extreme development of the marking of T. opalinoides.
Taxonomic notes. This species is tentatively associated with true Thalassodes, though
it lacks red marginal markings and genitalic coremata and other features such as
the oblique structure on the valve. The socii are narrow and the vinculum is
cruciform. There is a scobinate semicircular flap on the sacculus and a
triangular process just ventral to the valve transtilla. This is oblong in
material from the S. Moluccas: also the saccular lobe is absent and the anellus
bears coarse spines in each side. The species is thus somewhat intermediate
between Thalassodes and the next genus.
Geographical range. N.E. Himalaya, Sundaland, Sulawesi, S. Moluccas.
Habitat preference. The species is frequent in the upper montane forest zone, ranging
from 1600m to almost 2000m.
