(Figs 167–173)  
 Type material. Holotype male, BRAZIL: Santa Catarina State, Urubici, Morro da Igreja, cloud forest, 1.822 m a.s.l., 18.ix.–05.xii.2004, Malaise trap, L.C. Pinho & L.E.M. Bizzo (MZUSP).   
 Diagnostic characters. The species groups with P. windwardensis in having virga not plate-like, without lateral lamella, R 4+5 ending proximal to M 3+4 and palpomeres not reduced; it can be separated from P. windwardensis in having inferior volsella not placed posterior on gonocoxite.   
 Etymology. Named after Luis C. de Pinho, who collected the specimen.   
 Male (n = 1). Total length 1.85 mm. Wing length 1.25 mm. Total length / wing length 1.48. Wing length / length of profemur 2.89.   
 Coloration. Thorax, abdomen and legs pale brown.   
 Head. AR 0.84, ultimate flagellomere 292 µm long. Temporal setae 8, including 5 inner verticals and 3 outer verticals. Clypeus with 4 setae. Tentorium, stipes and cibarial pump as in Figure 167. Tentorium 107 µm long, 18 µm wide. Stipes 102 µm long. Palpomere (Fig. 168) lengths (in µm): 14, 32, 73, 78, 102. Third palpomere with 10 lanceolate sensilla clavata, longest 14 µm long.   
 Thorax (Fig. 169). Median antepronotal lobes reduced; antepronotum with 1 lateral seta. Dorsocentrals 11, acrostichals 2, prealars 3, supraalar absent. Scutellum with 6 setae.   
 Wing (Fig. 170). Wing with weak anal lobe. Cu 1 curved. R 4+5 ending proximal to apex of M 3+4. VR 1.67. Costal extension 57 µm long. Brachiolum with 1 seta, other veins bare.   
 Legs. Spur of fore tibia 42 µm long, mid leg lost, spurs of hind tibia 43 µm and 23 µm long. Width at apex of fore tibia 27 µm, of hind tibia 34 µm. Comb with 12 setae, longest 13 µm long, shortest 27 µm long. Length and proportions of legs as in Table 22.   
 Hypopygium (Figs 171–173). Anal point barely indicated, with 1 seta at base. Tergite IX with 9 additional setae. Laterosternite IX with 3 setae. Phallapodeme 84 µm long. Sternapodeme evenly rounded, without oral projections, arched part about 70 µm long. Virga consisting of 2 stout spines, 18 µm long, without lateral lamellae. Gonocoxite 138 µm long. Inferior volsella with subrectangular apex projecting caudad, reaching to 0.66 of gonocoxite length, with few marginal setae. Gonostylus 59 µm long; crista dorsalis barely indicated; megaseta 6 µm long. HR 2.35. HV 3.13.   
 Distribution and biology. The single specimen was collected at an altitude of about 1.800 m a.s.l. in a fragmented primary cloud forest belonging to the Mata Atlântica forest in Santa Catarina State, Brazil. The specimen was taken in a Malaise trap close to a small stream.
