We have not found any specimens matching the genitalia figures presented for this species by Cook & Scoble (1995: 27, Fig. 101) and we suspect that they wrongly attributed another (undescribed?) Oospila species to the NW Ecuadorian female holotype. The illustration of the primary type of Racheolopha extensata Warren on the NHMH homepage is superficially similar with our material which is described below. The combination of rounded posterior lobes of the last male abdominal sternite and the smallest harpe is characteristic of O. ehakernae sp. nov.
Diagnosis. Dark green moths with red-brown marginal band reaching from costa of fore wing to tornus of hind wing. Other species have much narrower and paler marginal bands (O. fimbripedata), or with markings not reaching the fore wing costa. For variability see remarks.
Description. Wingspan, 14–16 mm (Fig. 16). The frons is mottled brown and dark green. The palpi are stickshaped, light brown, clearly exceeding frons. The male antennae are bipectinate in the basal two-thirds, the length of the external and inner rami reaching 0.55–0.7 mm and 0.3–0.4 mm in length, respectively. The female antennae are thinly bipectinate in the basal half. The wings are green with a distal band, which expands basally at the fore wing costa. The marginal band is light rusty brown with grey-brown perimeters. The tornus of the fore wing and the tip of the hind wing are not darker in colour than the rest of the marginal band. The discal spots are dark grey. Abdomen: the crests are blackish on a broad brown stripe. Underside of wings, with the suffused, grey marginal band cut by light streaks along veins. Male hind tibia not hairy.
Male genitalia (Fig. 52): Diagnostic are (1) the short (0.8–1.0 mm) and very broad aedeagus with short stalk and a striate sclerite (i.e. no sclerotized cornutus) and (2) the semimembranous, bilobous sternite A8 with rounded or slightly edged posterior lobes. The harpe is usually small and very narrow, but slightly varying and in some slides somewhat longer and tongue shaped.
Female genitalia (Fig. 76): Overall length of female genitalia 3–3.5 mm. The anterior apophyses are short, almost triangular. The seventh segment bears two triangular patches of fine setae, and the sterigma is densely setose along its posterior edge. This vestiture is fur–like. The ostium is large, cup-shaped and folded; the signum is indistinct.
Genetic data. BIN: BOLD:AAD0955. n=15 barcodes from French Guiana and Peru. Nearest neighbour: O. ehakernae from Costa Rica (7.3%), O. similiplaga (9.3%).
Distribution. Ecuador (locus typicus of rufilimes in NW Ecuador [Esmeraldas]: River Cayapas); Peru (locus typicus of subruta: eastern Peru, Junin: Chanchamayo), eastern Brazil, French Guiana (locus typicus of extensata: Maroni River, St. Jean), Guyana (Cook & Scoble 1995), with new records from Bolivia and Colombia.
Biology. The material was collected in lowland tropical rainforests, at medium elevation up to 600 m, exceptionally up to 1000 m, and on cultivated areas with forest fragments, recorded in all months of the year except August.
Remarks. Most specimens show a very broad marginal band, similar with wing pattern of the type specimen of extensata (which may merit subspecific status, perhaps, for the populations east of the Andes). A few barcoded and/or dissected specimens (e.g. ZSM G 17210; 17211; BC ZSM Lep 66257), however, were characterized by a narrower marginal band, more reminiscent of the type specimen of O. rufilimes, in one examined case not even reaching the fore wing apex, thus approaching the habitus of the type specimen of subruta.
