ETYMOLOGY. The species epithet derives from Ba Vi and refers to the national park where the species was discovered.

TYPE MATERIAL

Holotype ♂ (dissected, right hind wing mounted): [Coll. I. R. Sc.N.B., Vietnam, Hanoi pr., BaVi N.P., 21°4’4”N 105°21’30”E, 25-29.VI.2015 day collecting, Leg. J. Constant & J. Bresseel, I.G.: 33.092] ( RBINS). GoogleMaps

Paratypes: 2♂, 3♀: same data as holotype (1♂, 2♀: RBINS; 1♂, 1♀: VNMN) GoogleMaps .

DIAGNOSIS. The species is easily separated (1) from N. tubercularis by the colour of the tegmina (pale yellow-green in the latter, showing a black reticulum in N. baviana ), and (2) from N. grootaerti by the vertex more elongate in the latter (1.3 times as long as broad in the latter vs 1 time in N. baviana ).

DESCRIPTION.

Measurements and ratios: LT: ♂ (n = 3): 6.4 mm (6.3 – 6.5); ♀ (n = 3): 7.2 mm (7.0 – 7.4). LTg/BTg = 2.24; LV/BV = 1; LF/BF = 1.4.

Head: ( Fig. 1 A, C, D View Fig ) vertex subquadrate, yellowish with margins carinate, anterior and lateral ones black-brown; in dorsal view, anterior margin convex, posterior one concave and lateral subparallel; disc excavate with narrow longitudinal groove on basal half and often pair of parallel black-brown lines on anterior half. Side of head yellowish, narrowly black-brown along dorsal margin and around eye; black-brown line from ventral margin of eye to fronto-clypal suture. Frons elongate and smooth, black-brown with sides carinated, yellowish, and median carina yellowish, extending to base of clypeus. Fronto-clypeal suture marked with yellowish. Clypeus black-brown, elevated medially and with lateral margins yellowish. Scape short, ring-shaped; pedicel bulbous, dark brown. Labium brown with last segment longer than broad, and shorter than penultimate.

Thorax: ( Fig. 1 A, C, D View Fig ) yellowish dorsally. Pronotum very short with posterior margin and discal carinae laminate; disc concave with obsolete median carina and tubercles; broad black line extending from behind eye to lateroventral angle of paranotal lobes; outer margin of paranotal lobes narrowly yellowish, inner margin broadly yellowish. Mesonotum short, slightly coriaceous with obsolete median carina and obsolete impressed point on each side of disc; transverse carina along anterior margin; yellowish; black anteriorly to transverse carina. Tegulae dark brown.

Tegmina: ( Fig. 1 A, C View Fig ) broadly semicircular, subcoriaceous; yellowish with submarginal narrow black line from anterior angle to posterosutural angle, running on margin only on basal 1/5; apical half of lateral margin and posterior one very narrowly bordered with brown. Venation reticulate with main longitudinal veins barely distinct basally and numerous cross-veinlets. Veins and veinlets brown, more or less dark; yellowish and forming a pale area on anterocostal angle with cells dark brown; transverse area behind scutellum darker; a transverse row of 3-5 more or less distinct darker markings at mid length.

Hind wings: ( Fig. 1 E View Fig ) brown, unilobed, with veins darker, slightly shorter than tegmina. Venation reticulate with main longitudinal veins distinct basally (C, ScP+R, MP, CuA), anal area absent; numerous cross-veinlets; veins thicker and darker along antero-distal margin. Costal and cubital margins sinuate, distal margin rounded.

Legs: ( Fig. 1 A, B View Fig ) elongate and slender, brown with darker and paler markings. Tarsi, broad longitudinal zones on femora, carinae and apex of anterior and median tibiae, and lateral spines of posterior tibiae, dark brown. Posterior tibiae with 2 lateral spines on apical 1/3 and 6 apical spines. Metatibiotarsal formula: (2) 6/8/2.

Abdomen: ( Fig. 1 B View Fig ) dark brown ventrally with posterior margin of sternites bordered with yellowish.

Genitalia ♂: pygofer higher than broad and with posterior margin strongly sinuate and roundly projecting posteriorly in middle in lateral view ( Fig. 2 A View Fig ). Gonostyli ( Fig. 2 A, C View Fig ) elongate in lateral view with capitulum of style well developed, elongate and projecting dorsointernally; capitulum with 2 processes on dorsal margin, a basolateral laminate process pointed anteroventrally and a deep basal transverse groove. Anal tube ( Fig. 2 A, B View Fig ) 1.25 times longer than broad, slightly sinuate in lateral view, dorso-ventrally flattened with sides broadly rounded and apicolateral angles roundly projecting ventroposteriorly. Aedeagus strongly curved posterodorsally, rather simple ( Fig. 2 D View Fig ). Phallobase with lateral hook-shaped process projecting anterodorsally at basal half ( Fig. 2 D View Fig ); apex of process slightly curved laterally ( Fig. 2 E View Fig ); laminate processes separated apically, slightly dissymetrical with external margin of left process more convex apically ( Fig. 2 E View Fig ). Ventral lobe of phallobase broad and spatulate, slightly emarginate apically ( Fig. 2 E View Fig ).

BIOLOGY. N. baviana sp. nov. was collected at the end of June on lower vegetation, in moist evergreen low mountain forest at an altitude around 1100 m asl. Typical biotope for the species is illustrated Fig. 3 A View Fig . Most of the specimens were found sitting on broad smooth leaves ( Fig. 3 View Fig B-E).
