(Figures 13–16, 32, 54–55)
Diagnosis. The background colour of P. angeloi sp. nov. has a grayish appearance, being lighter than other species of the “ P. lamia species group”. Yellow stain restricted to the DFW discal cell in males or only to the distal area of the discal cell in females. Basal, discal, post-discal and submarginal lines are faint. Androconial patch characterized by the elongated dark central area (Fig. 32). Female slightly darker than male, and all ocelli are welldeveloped. Female papillae anales with a well-developed and curved posterior aphophysis similar to P. kesselringi sp. nov., but the ductus bursae approximately three times longer than corpus bursae, and the paired signa are located latero-ventrally (Figs 54–55).
Description. Head. Front white. Vertex white mixed with light brown. Antennae dark brown. Labial palpi with elongated white scales mixed with light brown externally and white on the inner margin. Thorax. Prothoracic legs white; meso and metathoracic legs brown on the upper side and lighter on the underside. Forewing length: male: 31–32 mm (n = 5); female length: 34–37 mm (n = 7). Forewing upper side (Figs 13–15). Mostly grayish brown, with a yellow stain covering the discal area. Forewing under side (Figs 14–16). Mostly light brown, outer margin dark and ripple pattern brown. Three reduced white incomplete ocelli in R5-M1, M1-M2 and M2-M3. Hind wing upper side (Figs 13–15). Mostly dark brown, lighter towards to base. Five incomplete ocelli in Rs-M1, M1-M2, M2- M3, M3-CuA1 and CuA1-CuA2, and the white pupil of the latter is reduced. Three black spots on the basal region. Four convex dark brown lines, the most distal line wider. Androconial patch with an elongated dark central area (Fig. 32). Hind wing under side (Figs 14–16). Similar to DHW. Outer margin light brown in males and brown in females, and five incomplete ocelli in Rs-M1, M1-M2, M2-M3, M3-CuA1 and CuA1-CuA2.
Male genitalia. Similar to P. lamia (see Figs 36–41).
Female genitalia (Figs 54–55). Tergum VIII trapezoid. Papillae anales with setae at the distal area, approximately three times higher than longer, sclerotized at the basal half. Sternum VIII not fused with the lamella antevaginalis. Corpus bursae completely membranous, with paired signa located latero-ventrally signa; ductus bursae about three times longer than corpus bursae, sclerotized and dilated on the anterior portion.
Distribution (Fig. 62). This species is restricted to semidecidual forests enclaves in Cerrado province of the Chacoan dominion at Maranhão state, Brazil. So far, P. angeloi sp. nov. is known only from the type locality and Tuntum (5°43’50”S 44°46’32”W), the latter with an unique record of a female collected in the 1970s.
Host plant. Unknown.
Etymology. The species name honors the Brazilian entomologist Angelo Barbosa Monteiro Machado.
