. Anterior margin of the head and head surface are covered with numerous bristles (sensilla chaetica); many of them have broken tip or are missing in the whole length. All bristles are grooved longitudinally. Shiny black mandibles are equipped with three teeth. Distance between tooth 1 and 3 is twotimes longer than greatest mandibular width. Tooth 3 is longer than 2 which is longer than 1. Mandible is typically equipped with 3–5 short bristles (sensilla chaetica) between mandibular base and tooth 1, 1 bristle between tooth 1 and 2, and 1 bristle between tooth 2 and 3. No bristles are found between the third tooth and pointed end of mandible. The intact bristles occur only in freshly hatched larvae; in older animals most of them are broken and often only a base of the bristle is seen. Bristles on outer margin of mandible are scarce and extend from its basal region to level of tooth 3. Inner jaw bristles are shorter than tooth 1, outer jaw bristles are shorter than tooth 3. Thoracic and abdominal morphology is like in first instar larvae. Sternite 9 is equipped with stout and pointed bristles. On the distal part of sternite 9 there are two bulges, each with four fossorial or digging bristles which are longitudinally grooved (Fig. 26). These digging bristles are longitudinally grooved less clearly than other bristles of the same larva.

of sensory receptors—campaniform sensilla, sensilla coeloconica and sensilla basiconica—are recognized for the first time in antlion larvae. Campaniform sensilla are recorded on the head, legs and abdomen. It is proposed that two campaniform sensilla on the 9th abdominal sternite play a role in digging into sandy substrate because these mechanoreceptors are known to detect stretch forces in cuticle (McIver 1985; Chapman 1998; Römer 2003). Sensilla coeloconica are present on the mandibles and maxillae of

These receptors play a role during catching behaviour when prey is grasped and fixed with mandibles and tip of mandibles and teeth penetrate a prey. It is suggested that antlions estimate taste of prey with these chemoreceptors.
