Diagnosis.

Larva. Following combination of characters differentiate L. paraoperosus from other species of the group operosus : maxillary palp much longer than galea-lacinia, segment II with slight distolateral excavation; labial palp segment II with broad thumb-like, apically rounded distolateral protuberance; labial palp segment III oblong.

Remark.

The larva has no morphological difference to L. paraoperosus from Indonesia ( Sumatra), but there is a genetic distance of 12 % ( COI, K 2 P).

Distribution.

Thailand (Fig. 32 c View Figure 32 ), but L. paraoperosus is known from Sumatra ( Indonesia).
