Diagnosis. FEMALE. Fore wing with ca. 6.5 mm; posterior ocelli approximate, distance between them equal to one ocellar diameter; pronotal carina distinct at sides; prominence in front of the fovea moderately elevated; mesoscutum with numerous conspicuous short bristles, also present on legs and metasoma; first metasomal segment rather short, very wide at apex; bristles on the propodeum and first sternum of the metasoma quite long and conspicuous; body mostly black, metasoma terga and sterna without conspicuous distal yellow bands. Proportional ratios: LSI/HMP— 0.93; LSI/WT1_AP—1.91; WT1_AP / BA—2.8. MALE. Unknown.

Description. FEMALE. Fore wing with ca. 6.5 mm; occipital-genal margin weak dorsolaterally and obsolete behind ocelli, but distinct laterally; gena narrow, width less than eye-width at level of ocular sinus; FHH/INTOW 1.05; malar space short; clypeus with apex rounded, slightly wider than high (HCLP/WCLP—0.87); clypeus with pale erect bristles, and pubescence not very dense or absent close to the apex; eyes practically bare; posterior ocelli approximate, distance between them equal to one ocellar diameter; pronotal carina distinct at sides; prominence in front of the fovea moderately elevated; mesoscutum, legs and metasoma with many conspicuous bristles; LMS/ WMS 0.98; scrobal furrow narrow and shallow above, obliterated below; propodeum inflated anteriorly and with a shallow but distinct cavity on the posterior region; first metasomal segment moderately short, with wide apex; sides of the first tergum gradually diverging towards the apex; dorsal profile of the first metasomal segment at apex convex; bristles on the propodeum and first sternum of metasoma quite long and conspicuous. Proportional ratios: LSI / HMP—0.93; LSI / WT1_AP—1.91; WT1_AP / BA—2.8. Almost entirely black. With small yellow spots adjacent to the inner side of the eyes; very thin or evanescent yellow band on the posterior margin of the pronotum, and on the distal margins of the metasomal segments. Legs light brown.
MALE. Unknown.
Nest ( Fig. 42 View FIGURES 37–42 ). Rounded to oval; envelope composed of wood fibers, dark brown with light brown stripes, rather fragile, without peduncle; diameter of cells 3.0 mm; whole nest ca. 4.5 cm long.
Distribution. Brazil: Amapá.
Remarks. This species presents a large amount of bristles throughout the body, especially on mesoscutum, propodeum and first metasomal segment, this pattern is not common in most of species of the group, but can be seen in some of them, such P. hecuba .
Etymology. The specific name is a tribute to Rosalina Ferreira de Castro , grandmother of the first author.
