Abstract The morphology of newly hatched larvae of the important parasitoid beetle Dastarcus helophoroides (Coleoptera: Bothrideridae) was examined by scanning electron microscopy. This study examined the morphological structures of the cephalic, the thoracic, and abdominal regions of newly hatched larvae, and the distribution of sensilla on these structures. Sensilla chaetica and sensilla styloconica were identified on the maxillae, labium and antenna, sensilla chaetica were identified on the labrum and mandible, sensilla basiconica, Bohm’s bristles and sensilla chaetica were found in the thoracic region, and sensilla basiconica were found encircling the body on all abdominal segments. In addition, our comparative morphological observations found no evidence of sexual dimorphism in newly hatched larvae in terms of shape, structure, sensilla distribution or typology.
