Members of the genus Alconeura are tiny leafhoppers (subfamily Typhlocybinae) that inhabit the undersides of leaves in tropical and subtropical forests. Like other microleafhoppers, they have slender, wedge-shaped bodies usually less than 4 mm long, translucent or brightly patterned wings, and hind legs with rows of small spines adapted for quick jumps. They feed by piercing plant tissues with their stylet-like mouthparts and drawing out sap.
