Ronkay, L.: New Stenoloba Staudinger, 1892 species from Taiwan and Vietnam (Lepidoptera: Noctuidae, Bryophilinae)

The male genitalia of the new species (Fig. 12) differ from those of S. olivacea (see Fig. 13 and KONONENKO & RONKAY 2000, Fig. 17) by their longer, significantly narrower uncus, more elongated, narrower valva, longer, narrower sclerotized bar of harpe-ampulla complex, thinner, more arcuate aedeagus, less inflated vesica with longer, stronger terminal cornutus and by the smaller medial cornuti field consisting of somewhat longer, stronger spiculi. Comparing the male genitalia of S. benedeki and S. futii (see Fig. 17 and KONONENKO & RONKAY, 2000, Fig. 49), the new species has much longer uncus, broader tegumen, distally broader, apically less tapering valva, longer sacculus, larger, stronger bar of harpe-ampulla complex and the vesica has terminal cornutus which is missing in S. futii. The female genitalia of S. benedeki (Fig. 14) differ from those of 5. olivacea and S. futii (see Fig. 15 and KONONENKO & RONKAY 2000, Figs 64-67) by their longer, broader, distally much more sclerotized ductus bursae and the subcorneal, partly smoothly sclerotized, partly folded cervix bursae. In addition, the antrum of the new species is smaller, more quadrangular than that of S. olivacea. Description - External appearance. Wingspan: 26-31 mm, length of forewing 13-15 mm. Body slender, head and thorax brown, collar, parts of tegulae and thoracic tufts pale greenish, marked with some blackish and white scales. Abdomen slender, dorsal crest well-developed, consisting of two large blackish-brown tufts. Forewing elongate, costa less arcuate, apex finely pointed. Ground colour pale, rather unicolorous mossy green, with fine golden-greenish shining; costal area irrorated with blackish grey scales. Basal dash a sharply defined, rounded spot; lower half of basal line also blackish, defined with white lines. Other elements of wing pattern less conspicuous, although costal patches of crosslines often rather strong, dark. Antemedial and postmedial lines distinct but relatively pale, dark grey, former double, waved, filled with ground colour, latter strongly sinuous, defined with whitish scales on both sides. Median fascia diffuse, interrupted; lower part of medial area strongly constricted, its outr part covered with dark grey scales between median fascia and postmedial line. Orbicular and claviform stigmata missing; reniform represented by its fine, lunulate inner line and a smaller outr streak, defined with a whitish-greyish patck between reniform stigma and postmedial line. Subterminal diffuse, brownish grey, partly interrupted; terminal line fine, whitish, followed by a row of dark spots between veins; cilia brownish-greenish, darker than ground colour. Hindwing large, rounded, whitish, suffused strongly with darker grey. Discal spot large, lunulate; transverse line diffuse, sinuous; marginal suffusion broad, veins also darkened. Terminal line dark brown; cilia white with interrupted brown medial line. Underside of wings whitish; forewing largely suffused with dark brown-grey, discal spot and transverse line present but diffuse; hindwing rather sparsely irrorated with dark grey, discal spot and sinuous transverse line conspicuous, dark brown. Male genitalia (Fig. 12). Uncus long, rather slender, with parallel margins. Tegumen high, relatively narrow; vinculum short; subdeltoidal. Valva simple, elongate, evenly tapering distally towards apex; apex rounded, with a few short spines at apical margin. Sacculus elongate, relatively broad; rudiment of clasper-harpe complex forming long, narrow, sclerotized, dorsally finely dentate plate. Aedeagus short, rather thick, distally finely arcuate; carina with sclerotized, short, relatively wide ventro-lateral plate. Vesica large, inflated, everted forward, recurved ventrally; distal half with three diverticula, one of them armed with large, thorn-like terminal cornutus, medial part with rather small cornuti field consisting of fine spiculi.
