species: ectozona Hampson,
genus is monobasic. The only species is small, white, with dark grey areas on
the forewing and a grey tinge towards the margin of the hindwing. The forewing
cell extends to beyond four fifths of the length of the wing and is distally
squared, with R1 and R2 branching off basad to its distal anterior angle and a
branching system of (R3 (R4, R5))
arising from the distal angle. M1 and M2 arise from the cross-vein, and M3
is connate with CuA1 at the posterior angle of the cell, with CuA2 arising from
the centre of CuA within the cell. The hindwing has four veins arising
independently from the distal part of the cell. The male antennae are filiform
but densely ciliate.
male genitalia have narrow valves that appear individual, apically tapering,
curved, acute, with an obtuse angle on the costa just basal to the tapered part.
The vinculum is slightly twisted on each side where it meets the tegumen. There
is a large juxta like an inverted ‘V’. The aedeagus vesica has no cornuti.
The eighth sternite of the abdomen bears a mass of black, needle-like scales.
