Diagnostic characters. The species differs from other members of the genus except P. tropis sp. n. by having a long virga with lateral lamellae. It differs from P. tropis by having a more curved gonostylus without outer corner.
Etymology. From Latin, lamellatus, equipped with plates, referring to the lateral lamellae of the virga.

Length and proportions of legs as in Table 17.
Hypopygium ( Figs 140–141). Anal point 12–26, 18 µm long, 7–14, 10 µm wide at base, with 4–11, 7 setae. Tergite IX with no additional setae. Laterosternite IX with 2–3, 2 setae. Phallapodeme 34–57, 47 µm long. Sternapodeme evenly rounded, with no trace of oral projections, arched part about 31–52, 43 µm long. Virga 33–47, 39 µm long; with lateral lamellae. Gonocoxite 79–104, 92 µm long. Superior volsella low, reaching to abouth 0.6 of gonocoxite length, fringed with strong, orally curved microtrichia. Gonostylus 34– 50, 40 µm long, with bluntly triangular apical crista dorsalis; megaseta 2–6, 4 µm long. HR 1.94–2.87, 2.24. HV 2.16–3.62, 3.01.
Remarks. This species and P. tropis sp. n. both have a long virga with lateral lamella otherwise only found in an undescribed Afrotropical Pseudosmittia . They thus must be regarded as only tentatively placed in the genus. P. palpina sp. n. apparently does not have virga with lateral lamella. However, its gonostylus looks exactly like the undescribed Afrotropical species and similar to that of P. lamellata .
Distribution and biology. The species apparently is widespread in Brazil as it has been taken in several nature reserves with Mata Atlântica forest along the Brazilian coast and also in a reserve in the middle of the Amazon forest in Amazonas State.
