( Fig. 4 B, D, F). Pe; THAILAND : Nan Prov., Mae Charim N.P., Nam Wa R., 18°36'N 100°59’E 335 m . asl., 13.iii.2002 , L-293 (Cranston). This unassociated pupa clearly belongs to Conochironomus . It differs from the likely pupa of C. tobaterdecimus (above) and ‘Nee Soon’ below, and may belong to C. nuengthai or C. sawngthai . Differences include the stronger cephalic tubercles and frontal setae ( Fig. 4 B), the spinose antepronotum which shows even some small hooklets ( Fig. 4 D), and perhaps the posterolateral corner (spur) of abdominal segment VIII ( Fig. 4 F).
