Scythropochroa gressitti Steffan, 1969 .

( Fig. 16 A–D)

[ Steffan 1969: 680–682, fig. 4 a–f].

Material studied: Holotype: Female , 2.i.1953, Micronesia, Caroline Islands, Truk Is., Tol Island (Tol), Mt. Unibot, 390 m, leg. J. L. Gressitt ( BPBM 8221 ).

Conservation status: Embedded in Euparal. Body, head and wings separated; wings under a separate cover slip. The morphological details are in rather good condition.

Comments. This medium-sized species is characterized by a large and club-shaped 1-segmented palpus, rather long flagellomeres, large wings with a long R 1, long R 5, macrotrichia on y and a few bristles on the mediotergite. The species appears similar to Scythropochroa latefurcata Enderlein from the Seychelles Islands however the relative lengths of the CuA-stem and fourth flagellomeres differ.

Distribution. Micronesia ( Caroline Islands).
