Comparative diagnosis

This new species differs from the type species of the genus by the following characters: furrow between second and third tergites present but shallow (without furrow in P. clotho ), face entirely densely reticulateareolate (mainly smooth in P. clotho ), antennal segments slender and longer (short and thick in P. clotho ), mesoscutum and mesopleuron distinctly reticulate areolate (very finely coriaceous in P. clotho ), neck long in dorsal view (short in P. clotho ), propodeum and petiole long (shorter in P. clotho ), radial vein arising behind middle of pterostigma (weakly before middle in P. clotho ), hyaline stripes on fore wing wide (narrow in P. clotho ).

Etymology
