Diagnosis
Body length: male 11–14 mm, female 16–19.5 mm. The triangle of golden pile on the mesoscutum places this species in a group together with P. aureoscutus, P. trilinea and P. trivittatus. From the latter two species, P. aureus differs by the absence of golden pile along the anterior and lateral margins of the mesoscutum. The species differs from P. aureoscutus in the triangle of golden pile on the mesoscutum being longer than wide and reaching the anterior half of the mesoscutum. In the male, the ratio vertex width:head width is approximately 1:3.3, and the lateral margins of tergite 2 are more or less parallel in the anterior half and diverging in the posterior 1/2 to 1/3. The female is figured in Fig. 102. As the female of P. aureoscutus is unknown, it is uncertain whether the characters described for the males of both species also apply to the females.
Description
Holotype: No. 23807, one female: Jatun Yacu, Rio Naxo, Watershed, 700 meter, Oriente, Ecuador (Wm. C. MacIntyre). This taxon is very similar to P. aureoscutus. Although both taxa were described by F.M. Hull, he apparently was unaware of this similarity, as Hull (1944b) only noted that it was ‘related distantly to beebei’ (a species nowadays placed in the genus Pseudomicrodon Hull, 1937).
