ETYMOLOGY. The species epithet refers to the type locality: Bidoup-Nui Ba National Park .

TYPE MATERIAL. Holotype ♀ (dissected, right hind wing mounted): Vietnam: [Coll. I.R.Sc.N.B., Vietnam, Lam Dong prov., Bidoup-Nui Ba N. P., 12°26’N 108°30’E, 21-25.VII.2014, Mal. trap, Leg. J. Constant & J. Bresseel, GTI project, I.G.: 32.779] ( RBINS)

DIAGNOSIS. The species is easily separated from (1) O. (Eupharos) tamdaoina by the apical spinose process of the tegmina (absent in tamdaoina ) and the by veins Sc and R of tegmina running separately from the basal cell (fused basally in tamdaoina ), from (2) O. (Orthophana) spinata by the brown colour of the tegmina (green in spinata ), the margin of tegmina slightly sinuate on apical half (rounded in spinata ) and the hind wings largely infuscate (white in spinata ).

DESCRIPTION.

Measurements and ratios (♀; n = 1): LT = 11.9 mm; LTg/BTg = 2.21; BV/LV (LV measured to level of anterior margin of eye) = 1.26; BF/LF (LF measured as the visible part in normal view of frons) = 0.71.

Head. brown. Frons and vertex concave, not separated by a carina, narrow with lateral margins slightly foliaceous ( Fig. 1 A-C). Head semicircular in lateral view with smooth antero-ventral angle ( Fig. 1 A ). Posterior margin of vertex slightly carinate and curved ( Fig. 1 C ). Lateral carinae of frons slightly projecting laterally then curved internally in obtuse angle before clypeus ( Fig. 1 B ). Frontoclypeal suture transverse, deeply grooved ( Fig. 1 B ). Clypeus strongly convex, not carinate, much longer than broad ( Fig. 1 B ). Ocelli very small. Scape ring-shaped; pedicel subcylindrical, about 1.5 times longer than broad ( Fig. 1 B ).

Thorax. pronotum brown, smooth with anterior margin strongly curved and posterior margin straight ( Fig. 1 A, C ). Paradiscal fields of pronotum wide behind eyes ( Fig. 1 A, C ). Paranotal lobes of pronotum elongate and broad, without carina ( Fig. 1 A ). Mesonotum brown with yellow dots on lateral fields; median and lateral carinae smooth, median carina narrowly yellow ( Fig. 1 C ).

Tegmina. crescent-shaped without hypocostal plate, brown with minute yellow spots, some bigger yellow spots along veins and black-brown marking at apical third between veins Cu 1 and M 1 ( Fig. 1 A, C ). Costal margin slightly sinuate and narrowly marked with yellow and black-brown alternately on apical half ( Fig. 1 A ). Apex with tooth-shaped spine formed by fusion of veins Cu 1+2 and M 2 ( Fig. 1 A, C ). Costal area broad ( Fig. 1 A ). Clavus slightly surpassing 2/3 of tegmen length, closed ( Fig. 1 A, C ).

Venation: ( Fig. 1 A, C ) C visible to 2/3 of tegmen length, densely furcate; Sc and R running separately from basal cell, simple, subparallel; M furcate at basal third; Cu furcate after half of tegmen; Cu 2 fused with costal margin after clavus and with Cu 1 before apex; A 1 and A 2 fused at half of clavus.

Hind wings. ( Fig. 1 D ) pale yellow, infuscate in middle basally and largely infuscate apically. Well developed, bilobed apically. Costal margin concave with coupling lobe after middle.

Venation: see Fig. 1 D .

Legs. elongate and slender. All tibiae with strong longitudinal carinae. Metatibiae with one anteapical lateral spine and 8-9 apical spines. Metatarsomeres with long setae ventrally; first and second with 2 strong lateral spines, first longer than second and with 10 small ventral spines arranged in arc ventrally.

Genitalia ♀. ( Fig. 1 E ) anal tube elongate and narrow, pointed apically, sinuate in lateral view with apex strongly curved ventrally. Gonoplacs subpentagonal with dorsal margin concave with a straight part in middle in lateral view. Apical margin of gonoplacs with numerous minute teeth.

BIOLOGY. The holotype was collected with a Malaise trap in moist evergreen mountain forest (1400 m asl.). The biotope around the trap is illustrated Fig. 2.

DISTRIBUTION. Recorded from the southern part of Central Vietnam, Dalat Plateau ( Fig. 4 ).
