Erythrolophus Swinhoe
Type
species: fascicorpus Swinhoe.
The
facies is described in the specific account below. The hindwing discal spot does
not consist of two white dashes as in some other genera, including the monobasic
Australasian tropical genus Pseuderythrolophus Prout.
The male antennae are bipectinate, unusually for the Rhodostrophiini,
and the hind-tibia has a scent-pencil. In the abdomen the tympanic bulla has a
sort of accessory lobe posteriorly, and the anterior margin of the second
sternite is narrowly fringed with short scales (Fig 154).
In the male genitalia the gnathus is strong and the uncus strikingly
bifid, each spatulate arm bearing a pad of fine setae. The valves are
triangular, bidentate apically: there is a slight lobe at the apex of the
sacculus.
The female genitalia have transverse, thickened
grooves flanking the ostium. The ductus is narrow, gently broadening out into
the rather elongate bursa. The latter lacks a signum.
