Type material. Holotype: male, TD29-R.106, Ro Koi, Sa Thay, Kon Tum Province, 20.v.2009, sweeping, 11º24’42.4’’N, 107º06’19.5’’E, 500m, leg Hoang Vu Tru ( IEBR).

Paratypes: 2 males, TD29-R.109, TD29-R.110, same data as holotype ( IEBR).

Etymology. The species is named after a colleague of the first author, Mr. Hoang Vu Tru, who collected the type specimens and supported the first author in various ways.

Description. Head: head (including eyes) as wide as mesonotum at base; vertex pale brown with the following black to fuscous markings: a median marking surrounding ocelli, of which the anterior tip reaches the frontoclypeal suture, a fascia on the posterior margin of the head; eyes brownish black, distance between lateral ocelli and the eyes more than twice the distance between two lateral ocelli; antenna brown-black; postclypeus brown-black with longitudinal streak and transverse groove yellow-brown, and a longitudinal central fascia; supra-antennal plate yellow-brown; gena with area close to eyes brown-black; lorum yellow-brown; anteclypeus brown-black with anterior margin yellow-brown; rostrum yellow-brown with black apex.

Thorax: pronotum pale brown, with a pair of central longitudinal fasciae that are broadened at both anterior and posterior ends, a pair of short, oblique branches stemming from the middle of the central longitudinal fasciae along paramedian fissures, a median transverse fascia along anterior margin of pronotum, a pair of obliquely longitudinal curved fasciae between median parts of paramedian fissures and posterior ends of lateral fissures, a pair of fasciae along lateral fissures, and a pair of curved fasciae along lateral parts of ambient fissure, black; pronotal collar pale yellow-brown, a narrow transverse fascia along posterior margin and a few indistinct spots on lateral parts, lateral part of pronotal collar slightly developed and dentate, lateral angle with black spot, posterior margin black; mesonotum pale brown, with a longitudinal black inner margin parapsidal suture brownish black; lateral sigilla with longitudinal black lines, scutal depression black; cruciform elevation pale brown ( Fig. 2 A); thorax in ventral view pale yellow-brown, with katepisternum 2, basisternum 2,3, meron 2, trochantin 2,3 black, and episternum 3 black.

Wings: fore and hind wings hyaline, with brown or fuscous veins.

Legs: ground color of all legs yellow-brown; fore leg with primary and secondary spine of fore femur, apical tibia, pretarsus, and pretarsal claw brown-black; mid legs with a fascia on trochanter, basal femur, apical tibia, tarsus, and pretarsal claw brown-black; hind legs with femur (excluding apex), tibial spur thumb of tibial comb, and pretarsal claw pale brown-black.

Abdomen: pale brown in dorsal view, with posterior tergite margins black, lateral anterior margin of tergite 2 with triangular black marking; timbal concealed with timbal cover in dorsal view; timbal cover pale yellow with brown-black streak on reaching from posterior to anterior margin, quarter round or trapezoid with lateral side more than twice as long as inner side and with anterior angles rounded; abdomen in ventral view pale yellow-brown, posterior sternite margins grey, sternites III and IV with a pair of well-developed, glossy, black, tubercles of the same size; posterior margins of sternites VII and VIII brown-black.

Operculum: black except lateral margin; triangularly shaped with apex narrowly rounded, inner margin widely convex and outer margin straight; long, nearly reaching posterior margin of sternite III, but not covering tubercles on sternite III; the two opercula are distinctly separated from each other at base.

Genitalia 3: pygofer pale yellow, oval in ventral view, lateral lobe of pygofer brown-black with recurved rounded apex, basal lobe of pygofer short, brown-black, rectangular as apex is almost straightly connected to anterolateral part of the pygofer. uncus consisting of a small median pale brown-black lobe with two rounded apices, and a pair of dark brown-black lateral lobes with slightly curved apex,

Measurements of types (in mm): body length: 22.8–23.0; fore wing length: 29.8–30.5; fore wing width: 9.6–9.8; head width: 6.8–7.0; pronotum width: 7.5–7.9; mesonotum width: 6.8–7.0.

Distribution. Vietnam (Kon Tum province). Figure 1 .

Biology. This species has been collected by sweep netting during daytime in the virgin rainforest at an altitude of 500 meters.
