Cautires asper Kleine, 1928

Differential diagnosis. Cautires asper (figure 94) shares entire terga and number of tergal processes with C. pulcher . C. asper is easily recognizable by white frontal part of pronotum, brownish black rest of body, long frontolateral process of dorsal plate of epicranium, and considerably reduced lateral plate of epicranium.

Measurements. BL 14.2 mm, PL 2.05 mm, PW 2.70 mm.

Material examined. Borneo, Sabah, km 53 Kota Kinabalu–Tambunan Rd., 1650 m, Gn Emas , 13.iv.2000, Bolm lgt., two mature larvae, one reared in the laboratory to the adult stage ( LMBC) .

Remark. C. asper belongs to the characteristic group of robust Metriorrhynchinae larvae with entire terga, fixed tergal processes, and short urogomphi. These species have two lateral processes at lateral margins of segments T1–T3, one process at A1–A8, and four processes at frontal margin of pronotum. Pleurites of T1–T3 and A1–A8 bears also more or less prominent processes. Although all these processes are very variable in length, they can be unambiguously homologized. On the other side, we found a similar larva, which differs in tergites of T1–T3 separated by wide membrane (figure 95).
