Material studied: Holotype : Male , 29.x.1952 , Hawai‘i I, Keanakolu , 1585 m , leg. C.P. Hoyt (BPBM, No. 2493); 2 males , 28.xii.2000 , Hawai‘i , Maui I. , Hana , rain forest, caught by net , leg. W. Mohrig (PWMP). Conservation status. Holotype is embedded in Canada balsam, head, antennae, palpus and wings isolated, wings under a separate cover slip. All morphological structures are in quite good condition. = Scatopsciara spiculata Vilkamaa, Hippa & Mohrig, 2012 syn. n. Scatopsciara spiculata Vilkamaa, Hippa & Mohrig, 2012 [Vilkamaa et al. (2012d): 69 – 70, fig. 2 A – D] Comment s. The species was combined by Steffan (1973a) erroneously into the genus Lycoriella near the species L. pallidor Tuomikoski. The rather short antenna, short palpus with a weakly deepened sensory pit, wing with short R 1 , fore tibia with a comb-like row of bristles, without a horseshoe-shaped border and gonostylus with an apical tooth and subapical spines, but without a whiplash hair on the inner side suggests it belongs to the genus Scatopsciara Edwards. The species is characterized by the gonostylus narrowed towards the apex with a strong apical tooth and 4 subapical spines, one spine near the base of the tooth, three spines separated in a row in the distal half of the inner side. The hypopygium of the type is somewhat depressed, so that the three spines on the inner side of the gonostylus seem to be inserted on an exposed keeled base (see Steffan’s comparison to L. pallidor Tuomikoski ). The two specimens from Maui represent the real morphological shape. It is conspecific with Sc . spiculata Vilkamaa, Hippa & Mohrig from New Caledonia (Vilkamaa et al. 2012d). The specimens from New Caledonia show apicolateral corners, which could be artefacts, due to flipped margins. The nodes of the flagellomeres seem to be somewhat more robust however all other morphological details are completely identical. Distribution . Hawai‘i; New Caledonia .
