Pseudolycoriella sylviae ( Steffan, 1969)

( Fig. 15 A–D)

Corynoptera sylviae Steffan, 1969 [ Steffan (1969): 705 –707, fig. 15 a–i].

Literature: Rudzinski (2000): 183.

Material studied: Holotype: Male , Caroline Islands, Palau Is., N.W. Ulebsehel (Auluptagel) I., 13.xii.1952, light trap, 25 m., leg. J.L. Gressitt (USNMENT 2083267) . Paratypes: 2 females, same locality as holotype, Dec. 1952, leg. L.H. Krauss ; 1 female, 12.xii.1952, NW Auluptagel, leg. J.L. Gressitt ( BPBM) .

Conservation status: Holotype originally mounted in Hoyer’s medium and remounted in Euparal in 1979. Body, head, hypopygium and wings separated, wings under a separate cover slip. Head and thorax deformed, strongly bleached.

Comments. The species is characterized by rather long flagellomeres (l/w index of 2.2), fore tibia with a small distinctly bordered bristle patch, and gonostylus with two rather long spines and a long whiplash hair. It is very similar to Pseudolycoriella bisulca Vilkamaa, Hippa & Mohrig from New Caledonia.

Distribution. Caroline Islands ( Palau, Pohnpei).
