(Figures 1E, F, 3C, D, 4B, 5C, 6C, 7C, 8C, 9D, 10C, 11C, 13C, 15, 21B, 22F)
Description
Adult. Colour: body dark brown. Head, including genae, frons, and clypeus usually lighter brown, vertex with a pale ochreous midline. Pronotum dark brown, small convexities behind eyes with light ochreous points. Mesopraescutum with a narrow pale ochreous triangle in the middle and two broader light brown ones laterally or entirely dark brown. Mesoscutum with four light brown bands or entirely dark brown. Mesoscutellum light ochreous to dark brown. Antenna off-white, segment 3 (and sometimes 4) entirely pale, segments 4–8 dark brown to black in apical half, segments 9–10 entirely black, terminal setae white. Legs dirty pale yellow with dark brown markings on all femora near base and apex, and on metacoxa; metatibia dark brown in basal half. Fore wing membrane clear, transparent, with dark brown pattern consisting of patches along veins Cu1a and Cu1b, apical parts of veins R1, Rs, M1+2, and M3+4, and at the touching point of Rs and M1+2. An irregular light to dark brown infuscation in the fore wing base and across the basal part of the vein R and veins M+Cu1 and M ( Figure 6C View Figure 6 ). Veins rusty brown, C+Sc, M+Cu1, R1, basal two-thirds of R, apical half of Rs and apical half of Cu1b, dark brown to black, as well as a spot on Cu1 fork, M fork, and the touching point of Rs and M1+2, and two spots on anal vein. Hind wing clear, transparent, vein C+Sc dark brown. Abdomen entirely dark brown, tergites sometimes with light brown markings dorsally. Male terminalia with subgenital plate dark brown, proctiger in apical half and parameres ochreous. Female terminalia dark brown.
Morphology: head, in dorsal view, slightly wider than mesonotum, subcylindrical. Vertex with microsculpture, matt, about twice as wide as long along midline, rounded down in front (Figure 1E). Median ridge on vertex raised, distinct, narrow. Vertex on either side of the median ridge relatively flat in front, not bulging; posterior margin deeply concave (Figure 1F). Lateral ocelli lying slightly above the plane of vertex on indistinct tubercles. Coronal suture reduced throughout. Occiput in dorsal view narrowly triangular. Preoccipital sclerite narrow; eyes not stalked, in frontal view subglobular. Genae slightly swollen. Tubercle below torulus pointed, forming an acute angle. Frons narrow, parallelsided. Clypeus pyriform. Antenna long, slender, segments cylindrical, weakly widening to apex ( Figure 4B View Figure 4 ); a single subapical rhinarium on each of segments 4–9; rhinaria elliptic with a wreath of cuticular spines ( Figure 3C, D View Figure 3 ); terminal setae subequal, the longer seta approximately as long as or slightly shorter than segments 9 and 10 together ( Figure 5C View Figure 5 ). Fore wing moderately elongate, outer anterior margin more or less evenly curved, apex truncate. Surface spinules present in small fields in apical part of cell r2 and cells cu1 and cu2 ( Figure 7C View Figure 7 ). Costal break in apical sixth of C+Sc. Hind legs long and slender. Meracanthus short, acute, pointed. Metafemur constricted medially. Metatibia bearing an open crown of eight or nine stout, unsclerotized apical spurs, and a few (one to five) similar spurs laterally. Metabasitarsus bearing two black sclerotized spurs. Dorsal margin of abdomen, in profile, slightly serrate; posterior margin of tergites 4 and 5 medially swollen into a tubercular process. Male terminalia as in Figure 8C View Figure 8 . Proctiger relatively long, slightly narrowing to apex. Subgenital plate, in profile, as long as high, dorsal margin straight. Paramere, in profile, relatively short and stout, medially slightly constricted and narrowing towards a broadly rounded apex; in posterior view, inner margin parallel-sided with outer margin; inner surface, covered in fine setae and three or four slightly stouter setae subapically, apex forming small sclerotized tooth ( Figure 9D View Figure 9 ). Basal segment of aedeagus stout; apical segment, with elongate head, which is apically widening, slightly hooked and broadly rounded, its dorsal margin angular basally; sclerotized end tube of ductus ejaculatorius relatively long, sinuate ( Figure 10C View Figure 10 ). Female terminalia as in Figure 11C View Figure 11 . Proctiger relatively long, with dorsal margin weakly concave, apical process long, narrowing to apex; circumanal ring with two rows of pores, pores of outer row not contiguous. Subgenital plate, in profile, relatively long, dorsal margin slightly concave, ventral margin straight; apex narrowly triangular, pointed; in ventral view, narrowly triangular, gradually narrowing into apical process with more or less straight margins, apex relatively broad and truncate ( Figure 13C View Figure 13 ). Dorsal and ventral valvulae lacking lateral teeth. Measurements and ratios in Tables I–III.
Fifth instar larva ( Figure 15 View Figure 15 ). Dorsum dirty yellow to light brown, venter pale yellow. Body flat, relatively slender, parallel-sided. Body marginally and dorsally covered with many pointed lanceolate setae. A pointed lanceolate seta present in anterior half of ocular region. Eyes with ca five distinct ommatidia. Antenna straight, short, with six segments; a single rhinarium apically on each of segments 5 and 6. Tarsal arolium moderately large relative to claws, with a broad pad and indistinct petiole ( Figure 21B View Figure 21 ). Abdomen dorsally on each side with five free sclerites and a completely fused caudal plate; apex of caudal plate broad, truncate. Anus in terminal position. Circumanal ring sinuate, situated apically, extending on to ventral abdominal surface. Measurements and ratios in Table IV.
Host plant
Nothospondias staudtii ( Simaroubaceae / Anacardiaceae ).
Biology
Free-living. The eggs are laid on the young leaves. The larvae live openly on the leaf surface and produce large quantities of honeydew on which sooty mould grows producing local necrosis on the leaves ( Figure 22F View Figure 22 ).
Distribution
Cameroon.

Etymology
Named after its host plant genus Nothospondias .
Comments
P. nothospondiadis sp. n. is close to P. kala sp. n. (see the comment under the latter). P. nothospondiadis differs from P. kala in the more reduced fore wing pattern (the membrane along the distal half of veins R and M, and the basal half of vein M1+2 is clear), the higher and more globular head, the shorter paramere, the shorter distal segment of aedaegus with a broader apical dilation, and the form of the female subgenital plate.
