Conservation status. Embedded in Canada balsam. Head, palpus, antennae and wings mostly separated, morphological structures in good condition.

Comments. Sciara molokaiensis Grimshaw (1901)  was inadequately described on the basis of a single female collected by R.C.L. Perkins in the Moloka‘i Mountains in September 1893. The female holotype, which we have not studied, is deposited in the BMNH. The re-identification of B. molokaiensis (Grimshaw)  is discussed by Steffan (1973a: 355). We follow the opinion of Hardy and Steffan that Bradysia molokaiensis (Grimshaw) sensu Hardy  belongs to the genus Bradysia  near to B. scabricornis Tuomikoski, 1960  . It is characterized by rough flagellomeres with the scape, pedicel and the first flagellomere pale yellowish; hypopygium short haired and with a closed base, an elongate slender gonostylus with 4 (sometimes 5) apical spines, a somewhat wider than long tegmen with a large area of fine teeth, a rather long aedeagus and distinctly toothed claws. The Hawaiian specimens were compared with the holotype of Bradysia aspercera Mohrig, 2016  from Papua New Guinea and they are identical. The specimens of B. molokaiensis (Grimshaw)  from Hawai‘i are also conspecific with Bradysia crassicornis ( Skuse, 1890)  , described from New South Wales, Australia, therefore B. aspercera Mohrig  and B. molokaiensis ( Grimshaw, 1901)  are junior synonyms of it.

Distribution. Australia; Hawai‘i; Papua New Guinea.
