ETYMOLOGY. The species is dedicated to Dr Patrick Grootaert, the head of Entomology at RBINS in acknowledgment for his permanent support and help to our projects in Vietnam.

TYPE MATERIAL

Holotype ♂ (dissected, right hind wing mounted): [Coll. I. R. Sc.N.B., Vietnam, Pia-Oac Mount , 22°36’N / 105°53’E, 03.VIII.2010, I.G. 31.668, Leg. J. Constant & P. Limbourg] ( RBINS). 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 brown reticulum and black spot on disc in N. grootaerti ), and (2) from N. baviana by the vertex less elongate in the latter (1 time as long as broad in the latter vs 1.3 time in N. grootaerti ).

DESCRIPTION.

Measurements and ratios: LT: ♂ (n = 1): 6.3 mm. LTg/BTg = 2.28; LV/BV = 1.28; LF/BF = 1.53.

Head: ( Fig. 4 A, C, D View Fig ) vertex elongate, yellowish with lateral and posterior margins carinate; anterior and lateral margins black-brown; in dorsal view, anterior margin convex, posterior one concave and lateral subparallel; disc excavate with narrow longitudinal groove on basal half and pair of parallel black-brown lines on anterior half merging in middle, leaving a pale, elongate yellowish spot behind anterior margin. Side of head pale yellowish, narrowly black-brown along dorsal margin and around eye; black-brown marking from anterodorsal part of eye to anterodorsal angle of gena; brown line from ventral margin of eye to fronto-clypal suture. Frons elongate and very slightly coriaceous between carinae; brown with sides carinated, pale yellowish, and strong median pale yellowish carina, extending to apex of clypeus. Clypeus brown with pale yellowish line along lateral margins. Scape short, ring-shaped; pedicel bulbous, dark brown. Labium brown with last segment longer than broad, and shorter and paler than penultimate.

Thorax: ( Fig. 4 A, C, D View Fig ) brown dorsally. Pronotum very short with posterior margin and discal carinae laminate; disc concave with obsolete median carina and tubercles; narrow pale yellowish line extending on posterior margin of pronotum to posterior and ventral margins of paranotal lobes, broadening at internoventral angle of lobes. Mesonotum short, slightly coriaceous with obsolete median and lateral carinae; transverse carina along anterior margin; slightly darker in middle; dark brown anteriorly to transverse carina. Tegulae dark brown.

Tegmina: ( Fig. 4 A, C View Fig ) broadly semicircular, subcoriaceous; yellowish-green with submarginal narrow dark brown line from anterior angle to posterosutural angle, running on margin only on basal 1/5; apical third 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 yellowish; transverse area behind scutellum slightly darker; brown marking at mid length merging to sutural margin.

Hind wings: ( Fig. 4 E View Fig ) yellow-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 slightly darker along distal margin. Costal and cubital margins sinuate, distal margin rounded.

Legs: ( Fig. 4 A, B View Fig ) elongate and slender, yellowish with darker and paler markings. Broad longitudinal zones on femora, carinae and apex of anterior and median tibiae, and lateral spines of posterior tibiae, brown. Posterior tibiae with 2 lateral spines on apical 1/3 and 6 apical spines. Metatibiotarsal formula: (2) 6/8/2.

Abdomen: ( Fig. 4 B View Fig ) brown ventrally with basal sternites yellowish.

Genitalia ♂: pygofer higher than broad and with posterior margin strongly sinuate and roundly projecting posteriorly in middle in lateral view ( Fig. 5 A View Fig ). Gonostyli ( Fig. 5 A, C View Fig ) subtriangular in lateral view with capitulum of style well developed, elongate and projecting dorsointernally; capitulum with 2 processes on dorsal margin, two basolateral processes pointing lateroventrally and a deep basal transverse groove. Anal tube ( Fig. 5 A, B View Fig ) 1.20 times longer than broad, slightly curved in lateral view; dorso-ventrally flattened with sides broadly rounded and apical margin cut nearly straight in dorsal view, and lateroapical angles slightly projecting ventrally. Aedeagus strongly curved posterodorsally, rather simple ( Fig. 5 D View Fig ). Phallobase with lateral hook-shaped process projecting anteriorly at basal half ( Fig. 5 D View Fig ); laminate processes separated apically, slightly dissymetrical with external margin of left process projecting externally in a thin lamina ( Fig. 5 D, E View Fig ). Ventral lobe of phallobase broad and spatulate, slightly emarginate apically ( Fig. 5 E View Fig ).

BIOLOGY. N. grootaerti sp. nov. was collected on lower vegetation, in moist evergreen tropical mountain forest at an altitude between 1600 and 1900 m asl.
