Diagnosis. Cranionycta (Nefrendinycta) atrazonaria ( Figs 52, 53 View FIGURES 51–54 ) externally can be distinguished from its sister species C. (N.) dieteri ( Fig. 51 View FIGURES 51–54 ) by its larger size (wingspan 33 mm vs. 28 mm, respectively); the darker greyish forewing with occasionally brownish in the inner half of the antemedial field, the reniform stigma and the outer part of the medial field; the more indistinct antemedial line; the darker orbicular stigma; the somewhat more irregularly curved medial line; the wider medial fascia; the less contrastingly marked and more crenulate, rather greyish-white postmedial line; and the somewhat more indistinct wider tornal streak.
The female genitalia differ ( Fig. 113 View FIGURES 107–113 ) from those of C. (N.) dieteri ( Fig. 112 View FIGURES 107–113 ) and C. (N.) albothoracica ( Fig. 111 View FIGURES 107–113 ) by the shorter appendix bursae with a relatively smaller distal turn and a wider but shorter terminal twist; and, additionally, from those of C. (N.) dieteri by the wider ductus bursae; and from those of C. (N.) albothoracica by the less ribbed ductus bursae.
In the female 7 th abdominal segments ( Fig. 146 View FIGURES 140–146 ), the sternite has slightly convex, and parallel lateral sides with slightly more pointed distal corner, and somewhat wider, more outstanding semi-circular distal band than C. (N.) albothoracica ( Fig. 144 View FIGURES 140–146 ) and C. (N.) dieteri ( Fig. 145 View FIGURES 140–146 ).
Description. Imago ( Figs 52, 53 View FIGURES 51–54 ). Wingspan 33 mm. Head. Relatively large; 2 nd segment of palpus longer than 3 rd; antennae filiform. Thorax. Moderately wide, whitish-grey suffused with blackish scales; patagia whitish-grey with wide blackish outline; tegulae whitish-grey suffused with blackish scales. Abdomen. Whitish-grey with some darker middorsal scale tufts. Wing. Forewing narrow, elongate, apically obtuse, whitish-grey with ochre; basal spot blackish, moderate, more or less triangular; basal streak indistinct, blackish, wide, short, wedge-shaped; tornal streak indistinct, blackish, long, between medial and postmedial lines wide, between postmedial and terminal lines thin; apical dash absent; basal line blackish, double, indistinct, outer line narrow, inner line very short, dot-like, filled with dark greyish-black; antemedial line double, reduced, thin, filled with whitish-grey-ochre scales, more or less continuous with three indistinct blackish spots at costal area or dashed, and with tiny blackish spot at outer edge of inner margin; medial line thin, blackish, irregularly curved, fused with conspicuously wide, blackish and outwardly fading medial fascia; postmedial line double, crenulate, inner line reduced or as developed as outer line, greyish-black, without narrow black stripe between veins R3 and M2, filled with whitish, suffused with grey, and with blackish scales at tornal streak; subterminal line narrow, zigzag, indistinct, whitish; terminal line whitish, interrupted by tiny, black on veins, most conspicuous on veins M1, Cu1 and Cu2; basal field dark greyish-black, narrow, fused with suprabasal patch, antemedial field and interior of basal line and joined to subbasal patch; subbasal patch whitish-grey, narrow and long; suprabasal patch reduced, greyish-ochre, more or less oval; antemedial field whitish-grey-ochre suffused with blackish scales throughout, with indistinct darker patch at costa; medial field inwardly whitish-grey suffused with ochre, outwardly more or less ochreous suffused with whitish-grey scales, both inner and outer parts moderately wide; subterminal field greyish-ochre suffused with whitish, and with large, brownish-grey, squarish patches in costal area, obscure between veins M1 and M2 and around tornal streak; terminal field narrow, whitish-grey; orbicular stigma reduced, slightly light whitish-grey with indistinct blackish, curved line inwardly; reniform stigma moderately large, reduced, ochreous, inwardly suffused with blackish scales, outline more or less complete or dashed; four narrow, whitish spots at costa between medial fascia and terminal line, gradually decreasing in size towards apex; tornal patch blackish, small; fringe whitish with greyish patches. Hindwing rounded, apically slightly pointed; fully greyish-brown; marginal band, postdiscal line, discal spot, and tornal patch slightly darker greyish-brown; fringe whitish with greyish patches.
Female genitalia ( Fig. 113 View FIGURES 107–113 ). Ovipositor rounded, slightly longer than wide, tapering posteriorly. Papillae anales weakly sclerotized, oval, densely hairy. Anterior and posterior apophysis equal in length, weakly sclerotized, rod-like; posterior apophysis with slightly extended distal end. Ostium longitudinally ribbed, moderately sclerotized. Antrum short, moderately sclerotized, more or less funnel-shaped. Ductus bursae short, moderately sclerotized, ribbed. Corpus bursae large, bulbous, weakly sclerotized; two opposing distal signa. Appendix bursae shorter than corpus bursae, coiled, moderately sclerotized, ribbed except in distal third, terminal twist short and wide, tapered; junction with corpus bursae long and narrow.
Female 7 th abdominal segments ( Fig. 146 View FIGURES 140–146 ). 7 th sternite quadrangular, as long as wide, weakly sclerotized with barely sclerotized, narrow semi-circular distal band; proximal edge straight; lateral sides slightly convex, parallel with slightly pointed distal corner and somewhat contrasting margin; distal edge concave. 7 th tergite roughly trapezoidal, slightly longer than wide, weakly sclerotized with slightly more sclerotized semi-circular distal band, and with indistinct, narrow and elongate window in distal middle; proximal edge more or less straight with two curved, somewhat sclerotized rods; lateral sides concave, slightly wavy with slightly contrasting margins; distal edge straight.
Distribution. This species is known only from south China (Prov. Guangxi, Jinxiu), relatively close to the type locality of C. (N.) dieteri (Prov. Guangdong, Lianping County).
Etymology. The name “ atrazonaria ” refers to the contrasting blackish medial fascia on the forewing.
The falcata species-group
This species group contains only one species which is externally very similar to other species in other species-groups in the subgenus Nefrendinycta . The main distinctive character can be found on the male genitalia (female unknown), such as the strongly billhook-shaped valvae, and the medial sclerite almost reaches the ventral margin (not parallel than in other species).
The male terminal abdominal segments can be characterised by the following features: the 8 th sternite is more or less trapezoidal, having a relatively wide distal edge without a sclerotized patch; and the rounded, distally abruptly cut off window with a slightly concave distal margin and a relatively wide, slightly constricted sclerotized stripe proximally. The 8 th tergite is triangular, proximal half more sclerotized; has a pointed proximal edge; much narrowing, narrowest in the middle lateral sides with relatively wide, triangular spur-like distal end; and a more or less rhomboidal window with a pointed peak proximally.
Distribution. Himalayan.
