Material examined

Dak Lak, Chu Yang Sin NP: 2♂ ( RMNH), 800–940 m a.s.l., 2–10 June 2007, Malaise trap, C. v. Achterberg and R. de Vries leg. ; Ha Tinh, Vu Quang NP: 1♂ ( RMNH), 69 m a.s.l., 18 ◦ 19 ′ 50 ′′ N, 105 ◦ 20 ′ 24 ′′ E, 4 March to 15 April 2011 ; 1♀ ( RMNH), 106 m a.s.l., 18 ◦ 17 ′ 41 ′′ N, 105 ◦ 25 ′ 42 ′′ E, 5 March to 15 April 2011, Malaise trap, C. v. Achterberg leg.

Diagnosis

Face with lateral part swollen, median part concave, upper margin U-shaped medially; propodeum with strong basal transverse carina, area superomedia closed; first tergite with median longitudinal carinae nearly extending to oblique grooves.

Distribution

Previously known from China, Taiwan, India, Sri Lanka, Malaysia, Indonesia and the Philippines ( Gupta 1962; Yu et al. 2005; Amanda et al. 2011), this is the first record of this species from Vietnam ( Figure 8 ).

Remarks

Five subspecies are currently recognized: T. clathrata clathrata , T. clathrata asaphia Gupta , T. clathrata flavolineata (Cameron) , T. clathrata javensis Gupta and T. clathrata malayensis Gupta. The Vietnamese specimens belong to T. clathrata malayensis , which differs from the others by its mesosoma and metasomal tergites with distinct black marks and epicnemial carina strong, extending to the anterior margin of the mesopleuron.
