Material examined. Holotype ♂, Brazil: MT, Nobres, Chapada dos Guimarães, -15.4720 -55.7660, 800 m, 14.iv.2016, Hymenaea courbaril (L.A. Pezzini) #587 (UFPR, dry mounted).
Paratypes. Brazil: MT: 1 ♂, 1 ♀, same data as holotype but -15.4652 -55.7200, 800 m, 31.viii.2016 (R. Ben- Hur) #69 (NHMB, slide mounted); 1 ♂, Nova Mutum, -13.5930 -56.0612, 430 m, 12.vi.2016 (L.A. Pezzini), #801 (NHMB, dry mounted); 1 ♂, same but -13.7023 -56.0712, 420 m, 12.vi.2016, Hymenaea, courbaril (L.A. Pezzini) #809 (NHMB, dry mounted); 2 ♂, 4 immatures, MT, Cuiabá, Campus UFMT, -15.6096 -56.0652, 150 m, 21.vii.2018, Hymenaea courbaril, park, plantation (D.L. Queiroz) #875(1) (NHMB, 70% ethanol).
Description. Adult. Colouration. Dirty yellowish. Antennal segments 4–6 brown basally, almost black apically. Thoracic dorsum with very indistinct whitish pattern consisting of spots and longitudinal lines.
Structure. Antenna 3.5–3.8 times as long as head width. Clypeus, in ventral view, rounded anteriorly. Rostrum moderately long, 0.4–0.5 times as long as head width, segment 3 0.8–1.0 times as long as segment 2. Forewing (Fig. 179) 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 sparsely, regularly spaced. Metatibia 0.8–1.1 times as long as head width. Terminalia as in Figs 188, 203–205. Male proctiger 0.5 times as long as head width. Paramere, in profile, lamellar, weakly weavy; 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. Distal portion of aedeagus inflated in apical third which is irragularly rectangular. 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 0.7 times as long as proctiger, ventral outline, in profile, relatively evenly curved; apex truncate.
Measurements (in mm) and ratios (1 ♂, 1 ♀). Head width ♂ 0.72, ♀ 0.82; antenna length ♂ 2.74, ♀ 2.90; fore- wing length ♂ 2.14, ♀ 2.62; male proctiger length 0.36; paramere length 0.22; length of distal segment of aedeagus 0.26; female proctiger length 0.58.
Fifth instar immature unknown.
Etymology. Adjective, female form. From Latin cultratus = knife-shaped, for the paramere shape.
Distribution. Brazil (MT).
Host plant, biology and habitat. Adults were collected on Hymenaea courbaril L., which is a likely host.
Comments. Platycorypha cultrata differs from other species of the Platycorypha atrifrons -group as indicated in the key. It resembles P. atrifrons and P. scalprata in the narrow, lamellar paramere. It differs from the two species in the apically distinctly more inflated aedeagus.
