Diagnosis. Plagiocephalus latifrons can be differentiated from P. lobularis and P. intermedius by the longest eyestalks (5.08–18.08 mm) ( Fig. 1D, E ); female parafacialia black ( Fig. 2D ); radial-medial band with base almost as narrow as the apex, at most barely touching the discal band ( Fig. 3C, D ). The species can also be distinguished by male frons with gold spot on anterior portion of ocellar triangle ( Fig. 1E ); male face yellowish white, with region close to antennae yellower ( Fig. 1D ); male scape, pedicel and first flagellomere entirely yellow ( Fig. 1D ), and female scape, pedicel and first flagellomere gold with apex sometimes darker ( Fig. 2D ); palpus yellow; male proboscis yellow, with yellow setulae, and female proboscis reddish yellow, with brown and yellow setulae. Male wing of normal outline, without posterior lobes ( Fig. 3C ); crossvein r-m almost at the level of apex of vein R 1 ( Fig. 3C, D ). Male fore and mid legs entirely yellow, and hind leg yellow to gold ( Fig. 1F ); female legs brown, with tarsi lighter, and fore femur yellowish on the apex ( Fig. 2F ).

Measurements: Male: Body: 2.55–3.75 mm; Wing: 4.05–6.8 mm. Female: Body: 2.85–4.00 mm; Wing: 4.75–6.48 mm; Oviscape: 1.05–1.5 mm.
