Description. Adult. Colouration. Orange or yellow, with hardly any dark pattern except for black frons and brown coronal suture, margin of vertex and bases of pro- and mesotibiae. Antennal segments 4–6 ochreous basally, almost black apically. Throracic dorsum with indistinct white pattern consisting of spots and longitudinal lines. Membranes slightly lighter than sclerites. Younger specimens with fewer dark elements.

Structure. Antenna 4.1–4.3 times as long as head width. Clypeus, in ventral view, rounded or almost straight anteriorly. Rostrum moderately long, 0.6 times as long as head width, segment 3 0.8–1.0 times as long as segment 2. Forewing ( Fig. 181 View FIGURES 175–184 ) 3.0–3.2 times as long as head width, 2.7–2.8 times as long as wide; cell cu 1 0.6 times higher than wide; surface spinules in cell r 2 above bifurcation of M moderately densely to densely spaced, arranged in irregular transverse rows. Metatibia 0.9–1.0 times as long as head width. Terminalia as in Figs 190 View FIGURES 185–196 , 209–211 View FIGURES 197–220 . Male proctiger 0.4 times as long as head width. Paramere, in profile, with square base and narrow lamellar apical portion; outer face with long, evenly spaced hairs; apex strongly sclerotised, forming an inward directed tooth; inner face with long setae which are thicker along fore margin in apical quarter. Distal portion of aedeagus inflated in apical two thirds, bearing two ventral lobes in the middle; apex hook short and wide. Female proctiger 0.7 times as long as head width, dorsal outline with bend in the middle, apical process weakly inflated; circumanal ring 0.3 times as long as proctiger. Female subgenital plate 0.5 times as long as proctiger, ventral outline, in profile, relatively evenly curved; apex forming small point.

Measurements (in mm) and ratios (1 ♂, 1 ♀). Head width ♂ 0.80, ♀ 0.84; antenna length ♂ 3.26, ♀ 3.62; fore- wing length ♂ 2.36, ♀ 2.72; male proctiger length 0.30; paramere length 0.18; length of distal segment of aedeagus 0.18; female proctiger length 0.62.

Fifth instar immature. Colouration. Sclerites light brown, membranes yellow. Antennal flagellum, tibiae, tarsi, the margins of the wing pads and the fore margin of the caudal plate dark brown or black.

Structure. Body 1.6 times as long as wide. Apical labial segment 0.5 times and antenna 3.3 times as long as forewing pad, respectively. Caudal plate 1.5–1.6 times as wide as long and 3.1 times as wide as circumanal ring; with two short dorsal capitate setae near dorsal sectasetae ( Fig. 195 View FIGURES 185–196 ).

Measurements (in mm) and ratios (2 immature). Body length 1.50–2.32, antenna length 1.60–1.74; forewing pad length 0.48–0.52; caudal plate width 0.62–0.68.

Etymology. Participle, feminine form. From Latin pinnatus = feathered, winged for the two ventral lobes adorn- ing the distal segment of aedeagus.

Distribution. Brazil (CE, PI).

Host plant, biology and habitat. Hymenaea courbaril L. The immatures are free-living.

Comments. Platycorypha pinnata differs from other species of the Platycorypha atrifrons -group as indicated in the key. It resembles P. rostrata in the paramere shape and the presence of ventral lobes on the distal segment of the aedeagus. It differs in the much shorter rostrum and details of the terminalia.
