Redescription of adults of Kribiodorum belalong Cranston (Diptera, Chironomidae, Chironomini) from Gunung Mulu National Park, Sarawak, Malaysia

The adult male of Kribiodorum belalong Cranston (Diptera: Chironomidae) was described only from a teneral adult specimen along with pupae. Certain key characters are unavailable or unmeasurable in the teneral form, e.g., wing dimensions, abdominal coloration pattern, and fine details of the hypopygium including the dorsal shape of the anal point. Here we redescribe and figure the adult male, and describe and illustrate the adult female of Kribiodorum belalong for the first time, both based on specimens recently collected in Gunung Mulu National Park, Sarawak, Malaysia. We provide some comments on the putative phylogenetic position of Kribiodorum Kieffer.
