Geijskes leg. District Brokopondo (formerly belonging to District Suriname): Brownsberg (mountain top, at midday, in sun shine) , 22.iii.1981, 1 ♂ (paratype), T. Keukelaar leg .

Male (holotype).— Total length ca. 45; abdomen 36; hind wing 21.5; costal edge of stigma in fore wing 1.4.

Head.— Labrum brown. Top of head brassy blackish-brown. Labium pale brown. Rear of head brown-yellow but cheeks largely blackish-brown and pruinosed.

Thorax.— Prothorax brown-yellow. Dorsum of pterothorax brown with a pair of metallic green antehumeral stripes on whole length of mesepisternum; these stripes two-thirds as wide as mesepisternum and not attaining mid-dorsal carina. Mesepimeron largely metallic dark green (or brown due to post-mortem changes) but brownyellow along humeral suture. Mesinfraepisternum largely brown, pale yellow near coxae. Metepi sternum, metepimeron and coxae pale yellow but metepisternum dark brown along femoral suture, and metepimeron with a dark brown spot below. Pectoral colour pattern shaped as shown in fig. 7. Pterothorax slightly pruinosed on ventral side.

Legs.— Pale yellow, the following dark brown: outer side of first femur, outer side of basal half of second and third femora, anterior side of femora and tibiae. Tarsi and claws entirely dark brown.

Wings.— Hyaline. Venation dark brown. Stigma brown. Postnodal cross-veins 14­ 13/13-13 in fore and hind wings, respectively. R3 branching between fourth and fifth Pns and between third and fourth Pns in fore and hind wings, respectively.

Abdomen.— Dorsum of segments brassy dark brown with greenish lustre. Lower sides of segments 1-7 pale brownish-yellow. Side spots on segments 8 and 9 and most of segment 10 yellowish-brown. Caudal appen dages brown and shaped as shown in figs 12-13.

Female (allotype).— Total length ca. 40; abdomen 32; hind wing 21.5; costal edge of stigma in fore wing 1.5.

Etymology.— The specific name edentatus from "e" and "dentatus", in reference to the complete lack of teeth on the inner border of the male superior caudal appendages.
