description: Plusiodonta stumpfi Behounek & Kononenko sp. n.
(Figs 5, 6, 11, 15)
Type material. Holotype: male, Philippines, Luzon Isl., Mountain Prov. Chatol, 16 km SE Bontok, 1600 m, fog jungles, 121°03′E, 17°02′N, 24.ix–14.x.1988, Černý K. & A. Schintlmeister leg. Coll. G. Behounek. Paratype: female, same locality, data and collectors. Coll. G. Behounek.
Diagnosis. Close to P. calcaurea (Figs 7, 8, 12, 17), externally differs by more less forewing apex and less expressed ventral wing extension, intensive dark golden-red colouration of forewing, less expressed wing pattern with vertical shape of reniform, smaller medial golden spot and small subapical dark spot. In male genitalia it differs from P. calcaurea (Fig. 12) by shorter uncus, somewhat narrower harpe with more expressed ventral and distal extensions of valve, broader cucullus without harpe (in P. calcaurea harpe present); aedeagus longer and narrower, vesica not armed. The female genitalia much broader than in P. calcaurea (Fig. 17), with broad papillae anales, stronger apophyses, broader antrum, relatively short and sclerotised ductus bursae and ovoid corpus bursae.
Description. Adult (Figs 5, 6). Wingspan 34–35 mm. Head and thorax covered with dark brownish-red with yellow scales, frons and palps yellowish-red; tegulae and patagia bordered with yellowish-red. Forewing triangular, with acute apex and extension in medial part of tornal edge (less expressed than in P. calcaurea) and cut from extension to tornal angle. Ground colour of forewing brownish-red in costal part of wing to postmedial line and bright red-brown with yellow from postmedial line to rest of wing, wing pattern formed by bluish-grey suffusion on dark part; basal line indistinct, like bluish-grey spot, antemedial line thin, bluish-grey, bordered with reddish brown; costal and medial areas with intensive bluish-grey suffusion; reniform darker then background, with bluish-grey vertical nucleus, encircled by thin bluish-grey line; area outward of reniform reddish-brown, without suffusion; postmedial line oblique, in costal and tornal part of wing expressed by thin bluish-grey line; subterminal field reddish-brown with yellow gold suffusion, two dark waved lines, black-brownish spot in distal part and clear golden spot in medial part; terminal area dark red-brown; terminal line whitish, disrupted, as a row of streaks and distinct whitish streak in medial part; cilia brownish, twin. Hindwing yellowish-grey, pale in basal part, gradually darker to terminal margin; cilia pale, yellowish-brown. Male genitalia. (Figs 11 a–c). Uncus, curved, somewhat stronger and shorter than in P. coenolota (Figs 12 a–c); scaphium sclerotised; tegumen 1.2 times longer than vinculum; valva rather broad, but narrower than in P. coenolota, extended and abrupt apically, with more smooth costal angle; apex of valva with two prominent extension on costal and ventral sides; sacculus broader than in P. coenolota, rounded, without thumb-like harpe like in P. coenolota, juxta formed with two slightly sclerotised lobes. Aedeagus somewhat longer than in P. coenolota, carina sclerotised, with prominent apical spine; vesica without cornuti (in P. coenolota carina armed with short spine, vesica with apical patch of small ripple-like cornuti. Female genitalia. (Fig. 15). Differ significantly from those of P. coenolota (Fig 17). Papillae anales quadrangular, broad; apophyses anterior and posterior ones strong, about equal in length; antrum broad, cup-like; ductus bursae sclerotised, flattened; corpus bursae ovoid, slightly ribbed in caudal part.
Etymology. The species name of the new species is dedicated to German Noctuidae collector Johan Stumpf.
Distribution and bionomic. The species is known only from the type-locality: Philippines, Luzon Isl., Mountain Prov. Chatol, 1600 m. The adults have been collected in foggy montane jungles in end of September to mid-October.
