( Fig. 12 A – CView FIGURE 12)

Plastosciara (Cosmosciara) longicosta Hardy, 1956  [ Hardy (1956): 75 – 77, fig. 3 a – d].

Material studied: Holotype  : Male, 24.xi.1952, Hawai‘i, O‘ahu, Hālawa Ridge, ex moss, leg. C.P. Hoyt (BPBM, No. 2482).

Conservation status. Embedded in Canada balsam. Head, palpus, antennae and wings isolated, wings under a separate cover slip. All morphological structures are rather well preserved.

Comments. The species is characterized by a 1-segmented palpus with a small rudimentary second segment, the basal segment not swollen, short oval and without a deepened sensory pit; antenna rather short, 4 th flagellomere with a l/w index of 1.2, hairs fine and somewhat shorter than the diameter of the basal node; legs slender, fore tibia without a distinct bristle patch; hypopygium with short and rather robust gonocoxites; gonocoxites with short and sparse hairs on the ventral inner side, gonostylus elongate, somewhat bulbous, apically with 2 fine and slightly curved spines and 2 fine subapical spines at the inner side. Hardy put the species into the genus Plastosciara  , subgenus Cosmosciara  . We agree with Hardy concerning the position in the genus Cratyna  (= Plastosciara  ) because of a shortened palpus and two pairs of fine spines on the inner side of the gonostylus.
