Oviposition behaviour, early instars and adult sexual dimorphism of Malachius (Malachius) prolongatus Motschulsky, 1866 (Coleoptera: Melyridae: Malachiinae) are described. Larval morphogenesis and the timing of developmental events are compiled and compared with larval development of three malachiine species studied before. Larvae of Malachius prolongatus at the time of egg hatch exhibit the most advanced morphogenesis currently known in malachiine beetles, especially in the development of labrum, antennae, mandibular condyles, maxillary and labial palps and prolegs. However, similar to previously studied genera, they also bear thoracic egg bursters.
