Description of adults by Burckhardt (1987) and Brown & Hodkinson (1988), and of immatures by Burckhardt (1987). The eight species described here form a morphologically homogeneous group, the Platycorypha atrifrons - group, which is characterised by the combination of following characters.

Adult. General body colour yellowish to light orange. Head short ( Figs 1, 2 View FIGURES 1–10 , 175 View FIGURES 175–184 ); coronal suture fully developed, slightly indented anteriorly and with a conspicuous black mark above median ocellus; toruli strongly raised; frons small, delimited by genae basad; lateral ocelli raised on tubercles; preocular sclerite and occiput large. Eyes relatively small, stalked. Antennal segments 1–3 light brown with apex of segment 3 almost black, segments 4 and 5 or 4–6 light brown basally and dark apically, the dark colour increasingly more extended from more basal to more apical segments, remainder of antenna dark brown or black. Rostrum long, apical segment as long as or longer than segment 2 ( Fig. 176 View FIGURES 175–184 ). Pro- and mesotibia with a dark spot on the outer face. Forewing ( Figs 177–184 View FIGURES 175–184 ) yellowish or orange, membrane and veins concolorous; elongate, fore and hind margin approximately subparallel, fore margin only weakly curved, apex irregularly truncate; pterostigma membranous, long, wide at base, evenly narrowing to apex. Membrane transparent, in apical half covered in dense surface spinules, generally denser in females than in males, with spinule-free stripes along the veins that are narrowing towards apex; basal half only sparsely covered in surface spinules with broad, spinule-free stripes along veins, often completely absent. Metatibia with conspicuous genual spine and 3+2 sclerotised apical spurs. Male proctiger slender, tubular, hind margin almost straight; male subgenital plate subglobular ( Fig. 185 View FIGURES 185–196 ). Basal portion of aedeagus sinuous in apical part ( Fig. 185 View FIGURES 185–196 ); distal portion with hook-shaped apex; sclerotised end tube of ductus ejaculatorius short, weakly sinuous ( Figs 199, 202, 205, 208, 211, 214, 217, 220 View FIGURES 197–220 ). Female terminalia cuneate ( Figs 186–193 View FIGURES 185–196 ). Proctiger with a transverse row of long setae in the middle. Circumanal ring oval, consisting of two rows of unequal pores. Valvula dorsalis cuneate, bearing a few teeth on dorsal margin apically, heavily sclerotised and pitch black at dorso-basal edge, dark colour conspicuously visible also in uncleared specimens; valvula ventralis weakly curved, lacking apical teeth; valvula lateralis membranous, rounded apically.

Last instar immature. Body dorso-ventrally flattened, sparsely covered in long capitate setae. Antenna 7-segmented; segment 3 with a pair of capitate setae in the middle and a single capitate seta near apex, segment 4 with a single capitate seta near apex. Thoracic sclerites small. Femora and tibiae bearing a few capitate setae; tarsal arolium petiolate, triangular, unguitractor developed, longer than claws, which are both developed and subequal in size. Forewing pad with marginal and dorsal capitate setae; hindwing pad with each a dorsal and marginal capitate seta and a marginal sectaseta. Caudal plate with varying capitate setae and 4+4 marginal and 1+1 dorsal sectasetae ( Figs 194–196 View FIGURES 185–196 ). Outer circumanal ring approximately heart-shaped, consisting of a single row of elongate pores.

Egg. Oblong oval, about twice as long as wide; irregularly narrowing at apex which is subacute ( Fig. 24 View FIGURES 22–26 ). Surface with granular microsculpture.

Comments. Platycorypha , a genus restricted to the Neotropical realm, contains six described species, for four of which host information is available. They are associated with the faboid legumes Erythrina (tribe Phaseoleae), Myroxylon (tribe Amburaneae) and Tipuana (tribe Dalbergieae ). Here we describe seven new species which probably all develop on species of the legume genus Hymenaea ( Detarioideae , Detarieae ). In the collection of the NHMB there are about 10 additional undescribed species, mostly associated with the legumes Sclerobium and Tachigali ( Caesalpinioideae , Caesalpinieae ) and one with Platymiscium ( Faboideae , Dalbergieae ).

The species associated with Hymenaea can be identified with the key below. The adult morphology is quite homogenous and species differ mostly in the paramere and distal portion of the aedeagus. We could not find any reliable characters to separate the females of the following species: Platycorypha amazonica sp. nov., P. atrifrons sp. nov., P. leptopeus sp. nov., P. pinnata sp. nov., P. rostrata sp. nov. and P. scalprata sp. nov.. Immatures are known only from three species.
