( Fig. 2 A–B)

Ctenosciara multispinosa Steffan, 1969 [ Steffan 1969: 712–714, fig. 17 a–j].

Material studied: Holotype: Male. 17.i.1953, Micronesia, Caroline Islands, Ponape I., Mt Temwetemwensekir , 180 m, leg. J.L. Gressitt ( BPBM 8225 ).

Conservation status: Embedded in Euparal. Body (thorax strongly deformed), head (without palpus), hypopygium and wings separated; wings under a separate cover slip. The morphological details needed for determination are in rather good condition but strongly bleached.

Comments. The species is characterized by macrotrichia on veins M 1, M 2 and CuA 1 (CuA 2 without macrotrichia), tarsal claws with a scutellate tooth-like structure, gonostylus short and slender, with a short apical tooth and 7–8 somewhat shorter awl-like spines, 4–5 above the tooth and 3 below in the apical third of the inner side. The body appears to contrast in colour, with a brownish thorax and yellowish abdomen, legs and antennae.

Distribution. Caroline Islands (Pohnpei I.).
