Abstract. Based on Chironomidae (Diptera) specimens collected from Gunung Mulu National Park, Sarawak, East
Malaysia, an additional two genera are recognised, belonging to the cosmopolitan tribe Chironomini. Two new
species, each represented by adult males, are described and illustrated as Paraskusella sarawak, new species and
Kribiodosis mulu, new species. The larva of Kribiodosis Kieffer, 1921 is described for the first time based on its
barcode identity to a male of Kribiodosis cantonensis Tang, 2021. New insights into phylogenetic relationships
are provided for Paraskusella Cranston, 2018 and Kribiodosis Kieffer, 1921 based on multi-gene analyses that
include these taxa. Each is located independently within a broad informal ‘Microtendipes–group’. Biogeographic
implications of these ‘tropical Gondwanan’ distributions are discussed briefly.
Key words. new records, new species, Borneo, phylogeny, distribution
