Agassiz, David, 2014, A preliminary study of the genus Nymphicula Snellen from Australia, New Guinea and the south Pacific (Lepidoptera: Pyraloidea: Crambidae: Acentropinae), Zootaxa 3774 (5), pp. 401-429 : 410-411

Nymphicula plumbilinealis sp. n.

Desription of imago (fig, 16). Wingspan 12–13mm. Head ochreous mixed pale fuscous; labial palpus terminal segment yellowish white, almost as long as second; second segment brownish; antenna pale fuscous. Thorax ochreous fuscous.

Forewing base pale fuscous; antemedian fascia broad, yellowish; costa fuscous between antemedian fascia and first strigula; median zone scattered with fuscous scales, more densely in costal half; first strigula yellowish on costa whitish beneath, outer edge ill-defined; second strigula yellowish on costa, then white, lower two-fifths leaden; terminal area yellowish orange; tornal spot leaden; cilia with strong fuscous cilia line, whitish above tornus.

Hindwing base fuscous; a white subbasal fascia; antemedian fascia whitish edged fuscous; small silver tornal spot followed by orange-yellow oblique streak in dorsal half; median zone densely scaled dark brown; submarginal line strong, fuscous; five distinct eye-spots separated by shining metallic studs, a larger shining leaden spot before first eye-spot; dark fuscous line in terminal cilia.

Abdomen ochreous, segments 4–6 suffused fuscous. Legs straw, male thickened with blackish scales on tibia and first tarsus; remaining tarsal joints also thickened, straw.

Tympanal organs (fig. 42): Venulae secundae strongly curved outwardly; venula media short; tympanum with a broad lobe extended anteriorly.

Male genitalia (fig. 64): Abdomen with a pair of hair pencils one third length of abdomen, and additional pair of hair pencils on eighth segment slightly longer than that segment; valva pointed, costa sclerotised; length 5.5x breadth; gnathos half length of uncus.

Female genitalia (fig. 85): Ostial chamber broad, half length of corpus bursae; ductus 0.4 x corpus bursae with signa comprising a weakly sclerotised strip for two-thirds of its length.

Material examined. Holotype ♂, Papua New Guinea | Southern Highlands| Tari 5000ft | 5.xi.1984 | D.J.L. Agassiz, deposited in Coll. BMNH.

Paratypes 2♂♂, Papua New Guinea | Southern Highlands| Tari 5300ft | 4.i.1986 | D.J.L. Agassiz, and same locality 12.i.1986, BMNH Pyralidae slide 23080 ( BMNH).

Diagnosis. Distinguished by the strong submarginal line of the hindwing; differs from fionae and other species in the oblique antemedian fascia of the forewing being suffused yellowish.

Derivation. from the leaden line in the hindwing.

Distribution. Known only from the type locality.
