Description. Adult. Coloration. Head ( Fig. 9B View FIGURE 9 ) and clypeus bright yellow to orange; vertex dark brown posteriorly. Antenna pale yellow, segments 3–8 with brown apices, segments 9–10 entirely brown. Pronotum dark brown, distinctly darker than vertex; mesopraescutum brown, often darker anteriorly; mesoscutum pale brown, brown posteriorly; mesoscutellum dark brown along margins, lighter brown in the middle. Metanotum dark brown. Forewing ( Fig. 15D View FIGURE 15 ) yellow, pale brown at apex and in cell a 2. Legs yellow to orange, metafemur dark brown at base. Abdomen yellow to orange, with dark brown sclerites; in female the first two tergites dark brown. Terminalia dark brown. Young specimens entirely pale yellow.
Structure. Forewing ( Fig. 15D View FIGURE 15 ) oviform, widest in the middle, broadly rounded apically; C+Sc weakly curved in distal third; pterostigma slightly narrower than r 1 cell, weakly convex in apical third; Rs straight in basal three quarters, weakly curved to fore margin apically; M longer than M 1+2 and M 3+4; Cu 1a mostly weakly curved to anal margin apically, ending at M fork; cell cu 1 narrow; surface spinules present in all cells, forming distinct hexagons of a single row of spinules, leaving narrow spinule-free stripes along the veins, spinules becoming sparse in basal half of the wing and completely absent in basal half of cell c+sc. Hindwing with 3–5 + 4 grouped costal setae. Metatibia bearing 6–8 apical spurs, arranged as 3 + 3–5, anteriorly separated by ca. 5 bristles.
Terminalia ( Fig. 23Q–V View FIGURE 23 ). Male. Proctiger moderately produced posteriorly; densely covered with moderately long setae in apical two thirds. Subgenital plate subtriangular, in lateral view, dorsal margin sinuate, posterior margin relatively straight; with moderately long setae. Paramere, in lateral view, narrowly lanceolate; paramere apex, in lateral view, blunt, directed upwards, in dorsal view, apex blunt, directed upwards and slightly inwards, lacking distinct sclerotised tooth; both outer and inner faces with dense, moderately long setae; posterior margin with long setae. Proximal segment of aedeagus with apical part weakly subdivided. Distal segment of aedeagus straight in basal two thirds, with dorsal margin weakly sinuate; ventral process inserted in apical third of the segment, in lateral view, simple, broadly rounded apically, with dorsal and ventral margins subparallel, lacking lateral lobes; in dorsal view, ventral process broad, gradually widening towards apex, broadest subapically; apical dilation, in lateral view, moderately broad, rounded apically, in dorsal view, apical dilation narrowly oval, broadest medially, rounded apically; sclerotised end tube relatively short and weakly curved.—Female terminalia cuneate; densely covered with setae. Dorsal margin of proctiger, in lateral view, almost straight posterior to circumanal ring, weakly concave subapically, apex pointed, slightly turned upwards; in dorsal view, apex blunt; circumanal ring, in dorsal view, cruciform. Subgenital plate, in lateral view, abruptly narrowing in apical half, pointed apically; in ventral view, apex blunt.
Fifth instar immature. Coloration. Light; cephalothoracic sclerite, antenna, wing pads, legs and caudal plate pale brown.
Structure. Eye with one short, simple ocular seta dorsally.Antennal segments with following numbers of pointed sectasetae:1(0), 2(1), 3(0), 4(2), 5(0), 6(2), 7(1), 8(1), 9(0), 10(0). Forewing pad with 4–5 marginal pointed sectasetae; hindwing pad with two marginal pointed sectasetae; both pads lacking sectasetae or larger lanceolate setae dorsally. Metatibiotarsus long; tarsal arolium broadly triangular apically, 1.2–1.5 times as long as claws. Abdomen with three lateral pointed sectasetae on either side anterior to caudal plate. Caudal plate with anterior margin close to anterior margin of extra pore fields; with 2+2 or 1+2 pointed sectasetae on either side laterally, and three pointed sectasetae subapically, on either side of circumanal ring dorsally. Extra pore fields forming continuous outer and inner bands, consisting of small oval patches; outer band long medially, end pointing outwards. Circumanal ring small.
Host plant. Guatteria sellowiana Schltdl. ( Annonaceae ).
Distribution. Brazil (CE).
Derivation of name. Named after its host, Guatteria .
Comments. Melanastera guatteriae sp. nov. shares with M. australis sp. nov., M. dimorpha sp. nov. and M. obscura sp. nov. similar male terminalia, i.e. the narrowly lanceolate paramere and the simple ventral process which is inserted in apical third of the distal segment of the aedeagus. It differs from these species in the absence of brown dots on the forewing.
