Diagnosis.

Body size: male 7-13 mm, female 9-14 mm. The triangle of golden pile on the mesoscutum place this species in a group together with P. aureus   , P. aureoscutus   and P. trilinea   . From the first two species, P. trivittatus   differs by the presence of golden pile along the anterior and lateral margins of the mesoscutum. The male differs from P. trilinea   by tergite 2 being widened posteriorly (parallel-sided in P. trilinea   ), and by sternite 4 being evenly convex and short pilose (with bulge-like, long pilose tubercle in P. trilinea   ). Male genitalia as in Fig. 260 View Figures 256–261 . The female differs from P. trilinea   by sternite 3 being more or less flat and only narrowly separated from sternite 4 (instead of strongly arched and with wide intermediate membrane in P. trilinea   ).

Notes.

Body size variation is considerable in this species. The smallest males (known from Venezuela and the Brazilian state of Amazonas) measure only 7 or 8 mm, which at first sight gives the impression that they belong to a different species. However, many intermediates occur between these ‘dwarfs’ and the largest specimens, and all specimens are very similar in morphology and colouration.

Distribution.

Known from Amazonian parts of Brazil, Colombia, Peru, Suriname, and Venezuela.
