TYPE MATERIAL. — Holotype. 1 ♂, “ VIETNAM, Lam Dong Co.,/Bidoup NP, 2000m,/ 12°06.43N; 108°39.47E,/ 12-25. V. 2013 ” (printed white label), MNHN ( EH) 16439.

Paratypes. 3 ♂♂, 5 ♀♀, same data as holotype (printed white label), AMS.

ETYMOLOGY. — The specific name is the Latin adjective meaning “of a mask” in reference to the unusual shape of the male pygofer (especially the basal lobes) of this species, which gives an impression of a grotesque mask.

Median length of abdomen: male 11.5 (11.3-11.9), female 10.7 (9.8- 11.6). Width of head including eyes: male 5.0 (4.9-5.1), female 5.2 (5.0-5.4). Width of mesonotum: male 5.6 (5.4-5.7), female 6.1 (5.8-6.5). Width of posterior margin of abdominal tergite 3: male 6.7 (6.6-6.8), female 7.0 (6.6-7.2). Length of fore wing: male 26.7 (26.5-26.9), female 29.4 (28.5-30.3). Width of fore wing: male 9.0 (8.6-9.3), female 9.4 (9.0-10.1). Wing span: male 58.0 (56.4-60.2), female 63.7 (60.2-66.2).

DIAGNOSIS. — Head distinctly narrower than base of mesonotum. Pronotal collar with lateral margins straight or slightly convex. Fore wing with distinct infuscations. M2 derived from u3. Uncus gradually tapering to apex. Basal lobe of pygofer with acute and long apex and with spine-like distinct protrusion subapically. Aedeagus very slender and much protruding.

DESCRIPTION OF MALE

Head

Head distinctly narrower than base of mesonotum; reddish ochraceous (maybe due to discoloration) with the following black marks: median spot enclosing ocelli, with its anterior end reaching frontoclypeal suture; a pair of longitudinal spots between the median spot and eye; median horizontal spot along posterior margin of head. Distance between lateral ocelli and eyes slightly less than 1.5 times as wide as distance between lateral ocelli. Postclypeus moderately swollen; with black to fuscous fasciae along almost all transverse grooves. Anteclypeus mostly black except anterior and posterior parts. Rostrum with apex reaching posterior margin of hind coxae. Lorum fuscous to dark brown. Gena with fuscous mark between postclypeus and eye.

Thorax

Thorax brown to ochraceous with black to fuscous marks. Pronotal collar with lateral margins straight or slightly convex, not dentate; with very narrow fascia along posterior margin. Inner area of pronotum with the following marks: a pair of narrow median longitudinal fasciae; a pair of small spots between sub-posterior part of paramedian fissure and posterior end of lateral fissure; a pair of fasciae along lateral fissures; a pair of curved fasciae along lateral margins of inner area, but discontinued anteriorly. Mesonotum with the following marks: median longitudinal fascia; a pair of small roundish spots enclosing scutal depressions; a pair of fasciae along inner parts of parapsidal sutures; a pair of short longitudinal fasciae on posterior half of lateral sigilla; a pair of short fasciae along postero-lateral corners of mesonotum. Cruciform elevation with anterior subapical parts black.

Wings

Wings hyaline with marginal areas extremely narrow. Fore wing M2 derived from u3; M4 derived from u4; length between bifurcation point into M and M1 + 2 and bifurcation point into M and M3 + 4 1.3 times or less the length between bifurcation point into M and M3 + 4 and base of M; basal portion of RA2 one fourth to one third as long as longitudinal portion of RA2; basal portion of RA2 forming an angle of about 135 degrees to longitudinal portion of RA2. Fore wing with infuscations on r, r-m, m, and m-cu and bases of M1-4. Roundish infuscation present on each hind margin of RP, M1-4, and CuA1. R + Sc ochraceous or greenish ochraceous. Basal membrane and hind wing jugum gray.

Operculum

Operculum ochraceous without marks; very short, not reaching posterior margin of sternite II, oblique, parallelogram-like with corners rounded. Opercula apart from each other, with gap about as wide as operculum.

Abdomen

Abdomen distinctly longer than head and thorax together. Tergite 4 or 5 wider than other tergites. Tergites brown to dark brown with ochraceous sublateral parts on tergites 3, 4, 5, and 6. Timbal very small, semicircular.Timbal completely exposed. Ventral part of abdomen brown to dark brown.

Genitalia

Pygofer narrow, elliptical in ventral view. Distal shoulder angled. Uncus not bifurcate. Uncal lobe simple, lobular, slightly incised at apex. Basal lobe of pygofer with acute and long apex and with spine-like protrusion subapically. Aedeagus very slender and much protruding.

DESCRIPTION OF FEMALE

Operculum ochraceous, lozenge-shaped, with inner corner slightly extended inward and pointed; extending slightly beyond sternite II. Abdominal sternites dark brown. Ovipositor sheath moderately protruding beyond abdominal segment 9. Dorsal beak about one third as long as protruding part of ovipositor sheath.
