<paragraph pageId="0" pageNumber="1">Overall larval shape slightly fusiform, head region enlarged due to broad prostomium and expanded lateral lips of vestibule. Prostomium rounded anteriorly. Three pairs of black eyes present, comprising one pair of rounded median eyes, one pair of large lateral eyes, and one pair of large anterior eyes. Lateral and anterior pairs of eyes link with each other and form a dumbbell-shape almost divided into two equal parts by a deep constriction. Small mid-dorsal melanophore present on chaetiger I. A distinct paired melanophore occurs dorso-laterally from chaetiger II onwards, ramified in anterior chaetigers. Black pigment spots on sides of peristomium absent. Dot-like black pigmentation on pygidium.</paragraph>
