ABSTRACT: Mayfly larvae are usually characterised by the presence of paired abdominal gills on the first seven abdominal segments. Numerous taxa assigned to different families however possess additional membranous cuticular outgrowths on different body parts that are generally referred to as accessory gills. These accessory gills can be located on maxillae, labium, thoracic sterna or coxa. The present study compares the different structures of those accessory gills that occur in some taxa of Siphlonuroidea and Eusetisura. The homology of these outgrowths is discussed, and their possible phylogenetic relevance is evaluated.
