(Fig. 31)

Roederiodes wigginsi Wilder, 1981: 417 . Type locality: Cocos Island [05°32′N 87°02′W], Costa Rica.

Type material. HOLOTYPE ♀, labelled: “ COSTA RICA:/ ISLA DEL COCO/ Bahía del Chatham / 22-I-1967 / Ira L. Wiggins ”; HOLOTYPE/ Roederiodes / wigginsi/ 1980 Wilder [red label]”; California Academy/ of Sciences/ Type No. 13622” (CAS) [one wing missing; one wing mounted on microscope slide (No. 13622)].

Recognition. This species is very similar to R. notialis sp. nov., with the arista-like stylus twice longer than the pedicel and well developed scutal setae. Without associated males, species identification is mostly dependent on geographic locality.

Redescription. Wing length 2.3 mm. Female. Face and gena brown. Ocellar setae divergent, slender, shorter than pprn; vertical seta stronger than ocellar seta. Antenna with stylus twice as long as length of postpedicel; postpedicel ovate, not prolonged apically. Length of proboscis three-quarter head height.

Pleura brown, with postpronotal lobe and postalar ridge paler; prescutellar depression without pruinescence; acr damaged; 5 dc, well-developed; 1 pprn; 1 presut spal with several setulae; 2 npl with several anterior setulae; 0 psut spal; pal and sctl damaged; laterotergite with patch of setae; antepronotum with several setulae; lower proepisternum with pale setae.

Wing infuscate (see Wilder 1981, fig. 1); cell dm pointed apically, with base of M 1 and M 2 coalesced basally for short distance, subequal in length to crossvein r-m.

Legs dark brown; coxae slightly paler, without bluish pruinescence. Hind tibia without enlarged ventral setae.

Abdominal tergites dark brown, without bluish pruinescence; bearing short black setae.

Male. Unknown.

Distribution. This species is known only from Cocos Is., Costa Rica (Fig. 31).

Remarks. Associated males of this species are unknown and accurate identification of R. wigginsi must await their discovery.
