Diagnosis: This species was described by Hancock and Drew (1995) except for male and female postabdominal structures. Epandrium sclerotised with broad lateral surstylus, with no demarcation between them, proctiger as high as epandrium, cylindrical with three strong setae, phallus short (1.61 mm) with heavily sclerotised hood-shaped glans (1.02 mm). Oviscape dark brown to black, eversible membrane short (0.84 mm) with spicules on distal and proximal end with 3–4 projections, aculeus (0.95 mm) with a blunt aculeus tip, two prominent preapical setae; spermathecae black and bulbous.

Biology: Reared from internodal spaces of shoots of the bamboos Gigantochloa and Cephalostachyum in Malaysia and Thailand, the larvae entering the internodes of older bamboo shoots through holes made by larvae of Lasiochila Weise beetles ( Chrysomelidae : Hispinae ), living semi-aquatically in the water body of the internodal cavity and feeding on detritus or microbial growth ( Dohm et al. 2008).
