Diagnosis

Clypeus with median swellings; oblique black mark on mesopleuron connecting with black mark along lower half of mesopleural suture; first tergite 1.5–2.0 × longer than its apical width, with black bands, or sometimes with two nearly conjoined black spots.

Distribution

Previously known from China, India, Sri Lanka, Thailand, Singapore, 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

Three subspecies are currently recognized: T. maskeliyae maskeliyae , T. maskeliyae flavifemorata Gupta and T. maskeliyae schmiedeknechti Krieger. The Vietnamese specimens belong to the nominate subspecies, which is characterized by its mesopleuron with black marks, mid and hind femora with black stripes and metasomal tergites with black stripes rather than spots. Specimens from Vietnam have denser, moderate-sized punctures on the face.
