Behounek, G. & V. S. Kononenko, 2012, A revision of the “ Belciana ” kala Prout, 1924 species group with description of a new genus and two new species (Lepidoptera, Noctuidae: Pantheinae) from East Asia. Revision of Pantheinae, contribution VI, Zootaxa 3590, pp. 1-15 : 6-7

Anabelcia taiwana sp.n.

( Figs 11–13, 20, 26)

Type material. Holotype: male, NE Taiwan, Fushan Botanical Garden , 650 m ca, 24˚47’N 121˚33’E, 17–22.vi.2000 (leg. Schacht)/ Genit. prep. 7349GB (Coll. GBG/ZSM) . Paratypes: 6 males, Taiwan, County Taipei, Pi Hu , 450 m, 24˚54’02’’N, 121˚45’27’’E, 4–5.iv.1997 (leg. L. Peregovits & A. Kun), genit prep. Nos 7249, 7250 L. Ronkay ( HNHM) ; 1 male, Taiwan, Prov. Ilan, 700 m, Fu Shan Botanical Garden, 27–28.iii.1997 (leg. Csorba & Ronkay) ( GRB) .

Diagnosis. The new species is close to A. siitanae , but differs by brighter wing colouration with more developed bluish-green elements of wing pattern and brighter yellow hindwing with indistinct discal spot and wider terminal band. The male genitalia of A. taiwana differ from those of A. siitanae by somewhat shorter and thicker uncus, trapezoidal shape of juxta, stronger triangular clasper, and weaker saccular extension and by shape of valva which is broader basally and more constricted apically. Aedeagus, compared with A. siitanae , somewhat broader, carina with smaller spine, vesica more extended medially, dorsal diverticulum larger with a row of 10–12 spines being stronger than in A. siitanae . Female of the new species is unknown. A. siitanae and A. taiwana are two morphologically very close taxa, however, taking into account their restricted, allopatric and remote distribution ( A. taiwana — Taiwan I. and A. siitanae —South Primorye) and lacking of records of any of the two taxa in Korea or China between Primorye and Taiwan, we treat two these taxa as distinct species.

Description. Adult ( Figs 11–13, 20). Wingspan 40 mm. Head green, thorax bluish-green, patagia bordered with brown patch, tegulae bluish; abdomen yellowish-grey, with brown abdominal crest formed by tufts of black and brown erected scales. Ground colour of forewing bluish-green, with black, white and brown elements of wing pattern. Basal and lower part of subbasal area, bluish green bordered with blackish line; costal part of subbasal area blackish-brown; medial area bluish green, more clear in costal area; central part of wing from basal field to antemedial line filled with mossy-green suffusion; base of lines marked in costal area; medial line wide, distinct in costal area becomes thin or diffused to ventral margin of wing; orbicular and reniform white, area between stigmata filled with white, reniform surrounded with three black spots; claviform marked as whitish spot under Cu-trunk; postmedial line thin, black; subterminal field brown, uninterrupted, outside restricted by wide or narrow diffused bluish subterminal line; terminal field brown, with dark diffused streaks between veins; and row of bluish spots and bluish dashes on veins Cu1 and Cu2; terminal line as row of small black dots; cilia brown, paler opposite veins. Hindwing pale yellow, brighter and deeper than in A. siitanae , with indistinct antemedial and postmedial lines and broad brownish terminal band (broader than in A. siitanae ) which is darker in outer margin and with distinct anal mark formed by black and bluish-green dashes; cilia brown, yellowish at base and between veins.

Male genitalia. ( Fig. 26). Compared with A. siitanae uncus shorter, but broader basally; juxta trapezoid, with central bar and short medial extension; valva covered with strong non-removing setae, slightly curved, boarded medially, in basal and medial parts broader than in A. siitanae ;: cucullus shorter but broader than in A. siitanae , clasper triangular, stronger than in A. siitanae , saccular extension stick-like, pointed, not curved like in A. siitanae ; valva gradually constricted and rounded apically, its apical half is narrower than in A. siitanae . Aedeagus straight, broader than in A. siitanae , carina with triangular spine smaller than in A. siitanae ; vesica tubular medially extended, projected ventrally, somewhat broader than in A. siitanae with medial diverticulum larger than in A. siitanae on dorsal side, bearing a row of 8–10 medium-sized, needle-like cornuti. Female unknown.

Etymology. The species name derived from the type-locality—the Island Taiwan.

Distribution. (Map 38). Taiwan, apparently endemic species. The species was collected in the hilly areas of the northern part of the island (450–650 m), in dense, humid, deciduous woodlands nearby Taipei and subtropicalmonsoonic forests in the Fu-Shan arboretum.
