Diagnosis

The species is closest to Zanna bidoupana sp. nov., Z. chartieri Constant sp. nov., and Z.limbourgi Constant sp. nov., from which it can be separated by the following characters: basal portion of head ( Fig. 12B, E–F ) covered in moderately large, rather well-spaced, black pitting without ‘background’ of dense, very small black pitting (dense, irregular, rather large, coarse, sometimes coalescent black pitting in Z. bidoupana – Fig. 3B, E–F ; moderately large, rather well-spaced, black pitting with ‘background’ of dense, very small black pitting in Z. chartieri and Z. limbourgi – Figs 7B, E–F , 16B, E–F ); anal tube of male ( Fig. 13A ) rather flattened dorsoventrally, 1.95 times as long as high in lateral view and with ventral angle at midlength (rather high in lateral view, 1.60–1.65 times as long as high, with ventral angle in basal half in Z. bidoupana and Z. limbourgi – Figs 3A , 16A ); pygofer of male in lateral view ( Fig. 13A ) with posterior margin projecting into a large posterior lobe angularly rounded in midheight (posterior margin sinuate, forming a large, broadly rounded posterior lobe in dorsal half in Z. kusamae and Z. chartieri – Figs 3A , 7A ; posterior margin projecting posteriad in dorsal ⅓, in large, apically rounded lobe forming nearly right angle in Z. limbourgi – Fig. 16A ).

Etymology

The species epithet is a patronym dedicated to the famous Japanese artist Mrs Yayoi Kusama (1929–), whose artwork, extensively covered in dots, is reminiscent of the pattern on the body and tegmina of Zanna species.

Description

MEASUREMENTS AND RATIOS. LT: ♂ (n =1): 38.0 mm. LTg/BTg= 3.25; LH/BH=4.2; LF/BF=5.9; BH/ BPrH= 2.4; LH/LT= 0.39; wingspan (extrapolated): ♂: 45.2 mm.

HEAD ( Fig. 12B, E–F ). Strongly elongate, representing 39% of total length, gently and evenly narrowing towards apex with apical ⅓ more or less parallel-sided in dorsal view; apex weakly widening, obliquely cut in lateral view and with incomplete, rim-shaped orange carina (missing in ventral portion); pale pinkish brown with irregular, moderately large, rather well-spaced, black pitting, more dense in basal half, especially on sides, and with very minute pits towards distal portion; some larger black pustules on side, along carina of vertex. Lateral carinae of frons weakly zigzagged, distinct towards apex, upcurved near apex and merging into a short dorsal carina reaching apex; lateral carinae of vertex distinct towards apex, merging with upcurved part of lateral carinae of frons; median carina of vertex obsolete. Labium yellowish brown, reaching mesocoxae.

THORAX ( Fig. 12B, E–F ). Pro- and mesonotum pale pinkish brown irregularly covered in small black pitting with pits much smaller than space between them (on average); median carina obsolete.

TEGMINA ( Fig. 12A, C–D ). Strongly elongate and reticulate, pale (subhyaline) pinkish brown, moderately densely covered in minute to small black spots, mostly on veins, 3 slightly larger ones; costal and postclaval margins subparallel, weakly diverging from base towards apex and curved at level of apex of clavus; apical margin rounded. Veins yellowish in large basal portion. Clavus open.

VENATION. ScP+R forked in basal ⅓, MP forked more basally in basal 1/4; CuA forked near apex of clavus; PCu and A1 fused near apex of clavus; PCu+A1 fused with postclaval margin at nodal line.

HIND WINGS ( Fig. 12A, C ). Subhyaline, milky white with veins slightly darker, vein PCu dark brown in basal half; postclaval margin weakly emarginate at A1 vein, and infuscate along vein CuP.

VENATION. ScP+R and MP forked at distal ⅓; CuA forked slightly more basally then MP fork; PCu forked at basal ⅓; A1 forked close to base, A1 2 fused with A2 rather close to base and A1 2 +A2 forked slightly before reaching postclaval margin. Numerous crossveins in large portion along apical and postclaval margins.

LEGS ( Fig. 12A, C–D ). Pale pinkish stramineous, pilose, rather short and robust. Pro- and mesocoxae with few small black markings; all femora with few small to minute black spots, sometimes absent, and conspicuous black spots aligned in a ring in distal ⅓, sometimes coalescent; pro- and mesotibiae with dark brown spots in basal ¼, and with apex brownish; pro- and mesotarsi with segments blackish brown apically; metatibiae weakly brown basally with all spines apically blackish brown, 4–5 lateral spines and 8 apical spines; first metatarsomere with 11–13 apical spines ventrally; second metatarsomere with 9 apical spines ventrally; first and second metatarsomere with a dense pad of microsetae ventrally; third metatarsomere elongate with a subapical blackish brown ring. Metatibiotarsal formula: (4–5) 8/11–13/9.

ABDOMEN ( Fig. 12A, C ). Tergites smooth and shiny, yellowish brown; sternites (except pregenital one) yellowish brown with irregular small black dots more or less aligned into a transverse row.

MALE TERMINALIA ( Fig. 13 ). Pygofer (Py – Fig. 13A–D ) about 1.51 times as high as long in lateral view, robust with posterior margin projecting posteriorly into a large posterior lobe in midheight; lobe angularly rounded; sides weakly excavate in dorsal portion (visible in dorsal aspect, Fig. 13C ). Anal tube (An – Fig. 3A–C ) robust, 1.95 times as long as high and with ventral margin oblique in distal half and angularly projecting at a wide angle in lateral view; 1.26 times as long as wide in dorsal view, with lateral margins slightly diverging towards apex and apical margin bisinuate, weakly excavate in middle portion; suboval, more or less flattened dorsally, in caudal view; epiproct and paraproct strongly surpassing anal tube, angularly rounded posteriorly in dorsal aspect. Gonostyli (G – Fig. 13A–D ) elongate, 2.82 times as long as high; in lateral view, ventral margin broadly rounded and dorsal margin rather broadly rounded after lateral hook (lhg), apical margin rounded; lateral hook with basal portion projecting posterolaterad and dorsal hump in middle portion, and apex strongly curved lateroventrad; in ventral view, lateral protrusion at about midlength, rather strongly and angularly marked. Aedeagus ( Fig. 13E–H ) rather elongate with lateral processes (lpa) forming multiple lobes; dorsal process (dpa) strongly protruding dorsally in lateral view; dorsal endosomal process (dep) in dorsal view subtriangular with lateral margins very weakly curved (nearly straight) and rather wide median slit in distal portion.

Biology

The holotype ( Fig. 14A–B ) was collected sitting on a leaf of a short plant along a gravel road near the clearing around the station in Dong Nai ( Fig. 14C ).

Distribution

Vietnam: Dong Nai Province ( Fig. 5 ).
