INTRODUCTION
The genus Cyclodes Guénee, 1852 was
erected for its type species Erebus omma Hoeven,
1840 from Java. Hampson (1894) reported C. omma
Hoeven from the Indian limits (Sikkim, Assam,
Kerala). Snellen (1886) added the second species,
Cyclodes spectans Snellen from Indonesia.
Bethune-Baker (1906) included one more species,
C. pulchra Bethune-Baker from New Guinea.
Prout (1926) described one subspecies, C. omma
pulchrior Prout from Indonesia. Poole (1989)
catalogued only three species of genus Cyclodes
Guénee from the Globe. Sivasankarn et al. (2012)
listed the only species, Cyclodes omma Hoeven from
India.
In the present study, the type species C.
omma Hoeven of the genus Cyclodes Guénee has
been collected from the state of Mizoram and
redescribed after incorporating the characteristics
of male and female genitalia.
MATERIALS AND METHODS
The collection of C. omma Hoeven was made
with the help of light traps. The collected specimens
were killed with the help of ethyl acetate vapour
and processed with standard techniques in
Lepidopterology. The identification of collected
specimens was done with the help of keys
constructed by Hampson, 1894.

simple, flap like, attain its maximum width at middle,
a small triangular structure at basal-ventral region;
aedeagus vesica large with patches of weak

Description: Head pale fuscous; palpi upturned,
pale, fuscous at sides; antennae smooth; collar pale
brown with fuscous tips; thorax pale fuscous.
Forewing pale golden brown with green reflextions;
outer area whitish; apical area irrorated with purple
brown; a metallic blue ring spot below costa
embraced by the double sinuous antemedial line;
indistinct and sinuous medial, postmedial and
submarginal lines, the first angles at lower end of
cell, second dentate from costa to vein CU1.
Hindwing grayish fuscous; a curved postmedial
white band with a dark line on it; some blue marks
towards anal angle; a marginal black line. Underside
with indistinct lunulate postmedial pale line and traces
of sub-marginal line; blackish towards costa of each
wing. Abdomen pale brown.
Male and female genitalia: as described for
the genus.
Material examined: Mizoram: Hrangchalkwan
12.IX.2012, 1 and 1 .
Distribution: India (Sikkim, Assam, Mizoram,
Kerala), Sri Lanka, Java.
Remarks: Mizoram is the new distributional limit
