"Euproctis” lyclene Swinhoe
1904, Trans. ent. Soc. London, 1904:144.
sensu Schintlmeister, 1994: 120.
Diagnosis. Females of lyclene and both sexes of the next species are
distinctive and very similar, white with basal yellow and distal black markings
on the forewing as illustrated. Males of lyclene have both wings obscured
with grey, darker on the hindwing, and sometimes with a reddish tinge on the
forewing (one male of each taken in Borneo). The darker fasciation of the female
is still evident within the grey of the forewing. The genitalia of the two
species are distinguished in the diagnosis of the next.
Taxonomic note. Schintlmeister (1994) illustrated what is probably lyclene as postincisa
Moore, a related N.E. Himalayan species known only from females that are
larger, with reduced yellow fasciae and a straighter postmedial dark one.
The male of postincisa is probably the taxon variegata Moore,
with extensive dark grey areas on both wings but basic fasciation as in postincisa.
Both taxa were described in 1879, so priority needs to be extablished if
conspecificity is confirmed. The genitalia have a similar structure to that of wilemani
Collenette and allies (see below), but the venation is different, with R5
branching from Rs more distally than R2, rather than more basally, and with M3
and CuA1 in the hindwing separate rather than stalked. Also the aedeagus is
narrower, tapering with a less robust cornutus in the vesica, and the juxta is
pouchlike. The female does not have a quadrate sterigma. The signum is an oval
plate ringed with small spines all round except basally in a horseshoe shape.
Geographical range. Borneo, ?Sumatra.
Habitat preference. The holotype female is from Kuching in the lowlands
of Sarawak. The two males are from dry heath forest at Telisai in the lowlands
of Brunei (grey), and from dipterocarp forest at 170m near the Danum Valley
Field Centre, Sabah (reddish).
