Diagnosis
. F1–4 yellow, P1, T1 and M1 orange, Ts1 yellow, lush fringes on M1 and T1, palps vanilla colour. Neither dorsal median white strip of hair nor red clypeal moustache, Male copulatory organs with dorsal distal tegular lobe as well as distal and proximal tegular lobes. Female copulatory organs with proximal seminal duct short and straight. Can be separated from
P. boreoaitha
by the absence of dark colour patches on F1–F4 and the presence of a dorsal, distal tegular lobe, and from
P. bulburin
, by smaller size (75%), the
presence of a dorsal, distal tegular lobe and the absence of the red mat of hairs covering the clypeus and around AME found in
P. bulburin
.
