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).
