Diagnosis

The species is closest to Zanna chartieri Constant sp. nov., Z. kusamae sp. nov. and Z.limbourgi Constant sp. nov., from which it can be separated by the following characters: basal portion of head ( Fig. 2B, E–F ) covered in dense, irregular, rather large, coarse, sometimes coalescent black pitting with few smaller pits (moderately large, rather well-spaced, black pitting in Z. kusamae – Fig. 12B, E–F ; same but with ‘background’ of dense, very small black pitting in Z. chartieri and Z. limbourgi – Figs 6B, E–F , 15B, E–F ); anal tube of male rather high in lateral view ( Fig. 3A ), about 1.60 times as long as high, with ventral angle in basal half (rather flattened dorsoventrally, 1.95–2.14 times as long as high in lateral view, with ventral angle at midlength in Z. chartieri and Z. kusamae – Figs 7A , 13A ); pygofer of male in lateral view ( Fig. 3A ) with posterior margin sinuate, forming large, broadly rounded posterior lobe in dorsal half (posterior margin projecting into large posterior lobe angularly rounded in midheight in Z. kusamae – Fig. 13A ; 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 refers to the type location, Bidoup-Nui Ba National Park in Lam Dong Province, Highlands Vietnam.

Description

MEASUREMENTS AND RATIOS. LT: ♂ (n =10): 41.0 mm (38.2–43.1), ♀ (n=2): 41.9–42.0 mm. LTg/ BTg =3.48; LH/BH=4.0; LF/BF =5.3; BH/BPrH = 2.2; LH/LT =0.35; wingspan (extrapolated): ♂: 52.8 mm (49.2–55.5), ♀: 54.0– 54.1 mm.

HEAD ( Fig. 2B, E–F ). Strongly elongate, representing 35% of total length, gently and evenly narrowing towards apex; apex obliquely cut in lateral view and with incomplete, rim-shaped orange carina (missing in ventral portion); rather pale pinkish brown entirely covered in dense, irregular black pitting with smaller pits towards distal portion and majority of rather large, sometimes coalescent pits in basal portion. Lateral carinae of frons weakly zigzagged, more prominent towards apex, upcurved near apex and merging into a short dorsal carina reaching apex; lateral carinae of vertex merging with upcurved part of lateral carinae of frons; weakly marked, weakly zigzagged carina in middle portion of vertex, and some ‘cross-carinae’ between latter and lateral carinae of vertex. Labium pale brown, reaching mesocoxae.

THORAX ( Fig. 2B, E–F ). Pro- and mesonotum rather pale pinkish brown entirely covered in dense, irregular, strong black pitting with pits often larger than space between them and sometimes coalescent; median carina obsolete.

TEGMINA ( Fig. 2A, C–D ). Strongly elongate and reticulate, pale pinkish brown, progressively paler, subhyaline towards apex, basal portion densely covered with minute pink spots; all surface irregularly covered in small to rather large black spots, mostly on veins, larger ones slightly protruding, large middle portion with very dense small spots; costal and postclaval margins subparallel, weakly diverging from base towards apex and curved at level of apex of clavus; apical margin rounded. Veins orange 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. 2A, C ). Subhyaline, milky white with veins slightly darker, vein PCu dark brown in basal half; postclaval margin weakly emarginate at A1 vein.

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

LEGS ( Fig. 2A, C–D ). Pale pinkish brown, pilose, rather short and robust. Pro- and mesocoxae with some black markings; all femora with some small black spots and conspicuous ring in distal ⅓, formed from large, more or less coalescent, black spots; pro- and mesotibiae with some small black spots and with apex black; pro- and mesotarsi blackish brown; metatibiae brown basally with all spines apically black, 5–6 lateral spines and 8 apical spines; first metatarsomere with 11 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 blackish brown ring. Metatibiotarsal formula: (5–6) 8/11/9.

ABDOMEN ( Fig. 2A, C ). Tergites smooth and shiny, blackish brown bordered with yellowish along posterior margin; sternites pale pinkish brown with transverse irregular row of strong black dots and rounded, brown marking along middle portion of posterior margin, except pregenital sternite with large subtriangular blackish brown marking in middle.

MALE TERMINALIA ( Fig. 3 ). Pygofer (Py – Fig. 3A–D ) about 1.77 times as high as long in lateral view, robust with posterior margin sinuate, forming large, broadly rounded posterior lobe in dorsal half; sides excavate in dorsal portion (visible in dorsal aspect, Fig. 3C ). Anal tube (An – Fig. 3A–C ) robust, 1.60 times as long as high and with ventral margin oblique in large posterior portion and angularly projecting in lateral view; 1.2 times as long as wide in dorsal view and with sides nearly straight, weakly diverging towards apex; more or less round in caudal view; epiproct and paraproct slightly supassing anal tube, rounded posteriorly in dorsal aspect. Gonostyli (G – Fig. 3A–D ) elongate, 2.46 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 apex strongly curved ventrad; in ventral view, lateral protrusion at about midlength, rather strongly and angularly marked. Aedeagus ( Fig. 3E–H ) rather robust with lateral processes (lpa) forming multiple lobes; dorsal process (dpa) moderately protruding dorsally in lateral view; dorsal endosomal process (dep) in dorsal view subtriangular with lateral margins weakly curved and median slit in distal portion.

Biology

The specimens were collected at a mercury vapour light trap at Hon Giao station in July ( Fig. 4A–B ). The habitat around was a clearing covered in grass, herbaceaous weeds and small bushes ( Fig. 4C ).

Distribution

Vietnam: Lam Dong Province ( Fig. 5 ).
