Lineodini is a tribe of the species-rich subfamily Spilomelinae in the snout moth family Crambidae.
Lineodini comprise medium-sized moths, mostly with moderately broad wings, whereas in the slender, long-legged Atomopteryx and Lineodes, the wings are narrow and almost pterophorid-like.[2] Females exhibit only one frenular bristle on the hind wing base, with the exception of Rhectosemia, where two frenular bristles are present.[3]
The sacci tympani of the tympanal organ are ventrally open.[3]
In the male genitalia, the valvae are of variable shape, from very slender to relatively broad and triangular with a broad valva base or paddle-shaped with a narrow valva base. The valva apex is rounded to somewhat acute. The costa is straight to concave, as in other non-euspilomeline species. The fibula is variable in shape, being either slender and emerging from the costa base or shorter and emerging more from the centre of the valva; in Euleucinodes and Proleucinodes, the fibula is absent. The valva sacculus is usually simple, whereas in Leucinodes there is a distal sacculus process that is in close association with the fibula.[2] The posterior phallus is simple and unmodified or with sclerotized appendages.[4]
In the female genitalia, the ductus bursae is normally unsclerotized – a synapomorphy of Lineodini. However, in Leucinodes and Neoleucinodes the posterior ductus bursae, the colliculum and the antrum are often partially sclerotized often have a thickened mesocuticle.[2][3][4] The corpus bursae is membranous, but at least Rhectosemia antofagastalis and R. striata exhibit a small sclerotized signum.[2][5]

Food plants
As far as known, Lineodini feed exclusively on Solanaceae plants like tomato, eggplant, potato, Capsicum (pepper), Physalis and numerous others. The caterpillars tie leaves together or bore in the plant, especially in fruits,[3] by which they diminish or ruin the marketable value of the fruits.
