Diagnosis
This species is distinguishable by the distinctive double-lobed PLP and short and hook-shaped embolus tip directed in a clockwise path ( Figs 8C–D View Fig 8 , 9A–B View Fig 9 ).
Etymology
The specific epithet is derived from the Latin word ‘ lobatus ’ meaning ‘lobed’, loosely referring to its distinctive proximal lobe of the tegulum.
