Type species: marinaria
Species in this genus
resemble large, robust members of the Thalassodes group discussed next
but lack fasciae on their pale-striated sea green wings. There is a white discal
spot on the hindwing. The male antennae are typical of the Hemitheiti with
untidy, adpressed pectinations.
The male abdomen has the
setal patches of the third sternite weakly present or absent. The genitalia have
a slender uncus and socii of the Hemitheiti type. The valves are rather
paddle-like, unornamented, but the bases of the sacculi are fused into a slender
digitate pocket that echoes the structure of the unusually long, slender saccus.
There are no coremata. The aedeagus is robust, with a scobinate tongue-like
process arising laterally from the small vesica when everted.
The female has the
modified type of ovipositor lobes. The bursa is very large, rather foot-shaped,
set on a long, slender, irregularly sinuous ductus that is lightly sclerotised
and finely, densely scobinate. The ostium is funnel-shaped, irregularly folded.
The type species appears
to be associated with mangroves. Murphy (1990) described the biology of a
species from this habitat in Singapore that he attributed to E. discissa Walker
on the basis of rough scaling on the hind-tarsus, following Prout (1933, Gross-Schmett.
Erde 12: 102). Prout referred to material from Lower Burma as discissa but
the co-types are from India: the genitalia (slide 17431) have the tegumen more
hunched, the saccus broader and the valve somewhat shorter with a central
crinkle. Dissection of material reared by Murphy has shown it to be marinaria.
