Description

(based on female). Head dark brown, naked and glossy on both side, sparsely covered with yellow piliform scales with dark yellow scales on vertex. Antenna longer than forewing in male. Labial palp 1-segmented.

Female abdomen and genitalia (Fig. 17). Segment IX forming a complete ring, strongly sclerotized; concave dorso-laterally. Segment X consisting of lateral sclerites and a dorsal sclerotized plate; lateral sclerites simple, as broad as long, with digitate projections having an apical seta at terminal inner margin. Corpus bursae large, membranous, with long narrow neck region anteriorly; with signa composed of four fan-shaped sclerites at distal of neck region; distal end densely sclerotized. Ductus spermathecae arising from a round concavity. Genital chamber with a sclerite ventrally.

Remarks.

I. plicata can be distinguished from other species of Issikiomartyria based on the female genitalia in that having densely sclerotized zone at distal end of corpus bursae.

Bionomics.

Larvae feed on the thalli of Conocephalum conicum .
