FIGURES 13–18. Aq. lateralis larval head, 5th instar, SEM. 13 anterior, dorsal surface uppermost; 14 apex of galea; 15 dorsal; 16 ventral; 17 right maxillary palpus and antenna; 18 tip of sensory area maxillary palpus.

Material examined. JAPAN: Five fifth instars, bred in lab, population collected from Tokyo Metropolitan University, Minami–Ohsawa, Hachioji, Tokyo, May 28, 2008 (NHMHAU).

Diagnosis. Protergum with parallel sides; four pale areas, two at anterolateral corners, and two along lateral margin just anterior to the posterolateral corners; median line wide, reaching maximum width at anterior margin of thoracic tergum 3; thoracic terga 2, 3 with midlateral paler markings Figs 75, 76); abdominal glands with 4–7 spines including a median spine (Fu et al. 2009; Fig. 3); antennal segment 3 with closely adpressed finger like projections subequal in length to adjacent sense cone (Figs 13–17); mandibles lacking retinaculum (Fig. 68); palpi with terminal sense organs (Figs 13, 18).

Remarks. Okada (1928) first reported 10 pairs of bifid defensive organs along the sides of the body, and indicated an odour of resin and peppermint in both this species and Luciola cruciata . His figure 1b (page 102) of Luciola lateralis shows gills protruding from the sides with defensive organs on the right side of thoracic segment 3 and on either side of abdominal segment 3. Figure 75 herein indicates only the dorsal branch of the gills, while Fig. 76 shows both the dorsal branch and a short ventral branch on abdominal segments 3-5.

FIGURES 19–24. Aq. leii larval head, 5th instar, SEM. 19–20 anterior dorsal surface uppermost; 21 dorsal; 22 ventral; 23 right antenna; 24 tip of maxillary palpus.
