Diagnosis

Clypeus with two median swellings, more distinct in male than in female; mesopleuron with drop-like black mark joined or nearly joined to black stripe below subalar prominence; propodeum with vestige of basal transverse carina, pleural part of posterior transverse carina complete or partly present; first tergite 1.2–1.5 × longer than its apical width.

Distribution

This species was recorded from Vietnam for the first time by Garthwaite and Desai (1939). Outside Vietnam, it has been recorded from China, Taiwan, Brunei, India, Sri Lanka, Myanmar, Thailand, Malaysia, Singapore, Indonesia and the Philippines ( Gupta 1962; Yu et al. 2005; Amanda et al. 2011).

Remarks

Three subspecies are currently recognized: T. zebra zebra , T. zebra diluta Gupta and T. zebra iridipennis Cameron. The differences between these subspecies are based on details of the colour patterns. The specimens from Vietnam belong to T. zebra iridipennis , which is characterized by mostly black body markings, hyaline wings, dark brown antenna and dorsally separated, dark stripes on the hind femur.
