Diagnosis. Variable in wing pattern, usually with narrow marginal band, sometimes reduced to small fore wing tornus spots and small hind wing apical and tornus spots or even completely lacking the red-brown marginal pattern. Occasionally with similar wing pattern to O. similiplaga or to small-banded O. rufilimes . Ground colour more irrorated with black-brown striations. A slight brushing of the last sternite of male moths will uncover its shape, roundly bilobed posteriorly in O. ehakernae and O. rufilimes , incised V-shaped in O. similiplaga . reveals the shape of the

Description. Wingspan, ♂♂ 17–19 mm (Fig. 15). Frons and palpi pale brown, interantennal fillet white, vertex a red-brown band. Length of male palpi 0.65 mm, = diameter of eye, in female longer, 0.9–1.1 mm, 1.3–1.7 times diameter of eye, last segment very long. Male antennae bipectinate (last third filiform) with the longest, external and inner rami on the fifth segment reaching 0.65–0.75 mm and 0.5–0.55 mm in length, respectively. Female antennae are filiform over the whole length. Thorax green, greenish-ochre in the centre. Dorsum of abdomen pale green when being fresh, with dark brown crests. Male hindtibia with two spurs. Fore wing pattern see diagnosis. Discal spots small, dark, sometimes slightly diffuse, present on both wings. Marginal line dark grey, disrupted, fringe chequered yellow and brown at the vein ends.

Male genitalia (Fig. 51): Similar to those of O. rufilimes , differing in the somewhat longer aedeagus (length 1.05 mm) and in the downcurved, longer, and much broader harpe. Sternite A8 with slightly shallower central posterior incision.

Female genitalia (Fig. 75): Similar to those of O. rufilimes in presence of fur-like setose edge of sterigma and a similar pair of setae patches on the last sternite. Apophyses posteriores longer. Ostium broader, ductus bursae region more sclerotized, with an oblique, characteristically curved fold. Corpus bursae shorter.

Genetic data. BIN (BOLD:AAA0851), n=10 from Costa Rica, intraspecific variation low (0.75%). Nearest neighbours: O. rufilimes from Peru and French Guiana (7.3%), O. arpata (10.6%).

Distribution. Costa Rica.

Biology. The material was collected in low mountain tropical forests, from 390 to 1150 m above sea level, from January to June. Records for larval host-plants: Senegalia tenuifolia (Fabaceae) (D. Janzen & W. Hallwachs, pers. comm.) (cf. Fig. 89).

Etymology. Oospila ehakernae is named in honor of Ms. Eha Kern of Sweden and of the Barnens Regnskog (Childrens Rainforest Sweden) in recognition of her intense and enthusiastic support for Area de Conservacion Guanacaste since 1985.
