Length of male 10.0-10.8 mm. Head with anterior margin narrowly orange-brown, crown with few small symmetrical orange spots, face with broad transverse yellow band extended across middle of frontoclypeus, continuing onto thoracic pleuron and extended to mesepimeron; anteclypeus yellow with brown medial spot; scutellum with posterolateral margins yellow; forewing hyaline, veins brown.

Material examined.

Holotype male labeled "Luang Prabang/ Pak Neun./ 28.IX.1918/ R.V. de Salvaza.; Indo China./ R. V. de Salvaza./ 1918-1"; one male paratype, same data; one male paratype, [LAOS?]: Huat Mekong, Pang Ngeon, 15 V 1918, R. V. de Salvaza [BMNH].

Notes.

The species name is based on that of the type locality, a village on the Mekong River in northern Laos. "Pang Ngeon" could not be located in available gazetteers and databases but may represent an alternative spelling of the type locality. Additional specimens have not been found, despite extensive recent field work in Thailand and Vietnam.
