General body colour whitish to pale yellow. Antenna pale yellow to brownish, gradually becoming darker towards apex, segments 9–10 entirely dark brown. Forewing ( Fig. 14A) with pale yellow veins and clear to pale yellow membrane lacking pattern. Legs pale yellow. Abdomen including terminalia whitish, distinctly paler than thorax. Structure. Vertex trapezoidal, about half as long as wide, with distinct imbricate microsculpture and short setae ( Fig. 8A). Metatibia slender, bearing posteriorly open crown of 8–9 hardly sclerotised apical spurs. Forewing ( Fig. 14A) oblong-oval, with subparallel costal and anal margins, widest in the middle, evenly rounded apically; wing apex situated in cell r 2; C+Sc moderately curved along most of its length of its section between base and costal break; pterostigma long and narrow, in the middle distinctly narrower than cell r 1, with subparallel margins in basal two thirds; Rs almost straight, hardly curved to costal margin apically; M longer than M 1+2and M 3+4; Cu 1aweakly curved, ending at bifurcation of M; cell cu 1short and broad; surface spinules present in all cells, irregularly spaced, leaving narrow spinule-free stripes along the veins; spinules absent from basal two third of cell c+sc. Hindwing with 9 ungrouped costal setae. Terminalia ( Fig. 21A–G). Male proctiger long, distinctly produced posteriad medially; covered with dense, moderately long setae in apical two thirds. Subgenital plate subglobular, with posterior margin evenly convex; with moderately long setae. Paramere shorter than proctiger; in lateral view, lamellar, with anterior margin almost straight in basal two thirds and concave subapically and posterior margin straight to weakly convex in basal half and distinctly concave in apical half, hence irregularly narrowing in apical third, with blunt, upwards directed apex; in dorsal view, apex narrow, directed inwards, and slightly upwards and posteriad, with small apical tooth; in posterior view, outer face strongly convex medially and relatively straight in basal and apical thirds, apex directed upwards; outer and inner face with sparse, moderately long setae, posterior margin with long setae. Proximal segment of aedeagus apically narrow and strongly sinuate, not subdivided. Distal segment of aedeagus thick; dorsal magin almost straight in basal two thirds, ventral margin strongly inflated basally; apical dilation, in lateral view, oval, broadly rounded apically, subdivided from basal portion; in dorsal view, apical dilation narrow, with subparallel margins, narrowly rounded apically; sclerotised end tube short and slightly curved.—Female terminalia cuneate, long; covered with short setae. Dorsal margin of proctiger, in lateral view, distinctly concave in apical half, apex slightly upturned, narrow, blunt; in dorsal view, apex narrowly rounded; circumanal ring, in dorsal view, oval. Subgenital plate slightly shorter than proctiger, with long apical process; in lateral view, pointed, upturned apically; in ventral view, apex narrowly rounded.  Fifth instar immature.Unknown.   Host plant.Adults were collected on  Luehea divaricataMart.and  L. grandifloraMart.( Malvaceae) which are likely hosts.   Distribution. Brazil(MG, MS, PR).  Derivation of name.Dedicated to Flavia Queiroz Sant’Anna, daughter of D.L. Queiroz.   Comments.  Klyveria flaviae sp. nov.differs from both extant species known from Brazil,  K. crassiflagellata(Burckhardt)and  K. setinervis(Burckhardt), in the smaller body size (FL <1.4 versus> 1.6); distinct imbricate microsculpture on the vertex; the short, light-coloured antenna (AL <0.6 versus> 0.9; AL/HW <1.3 versus> 1.4); the evenly pale yellow and elongate forewing (FL/FW> 2.4 versus ≤ 2.4), with subparallel margins, and narrowly rounded apex; and details of the paramere shape bearing a single small apical tooth.  Klyveria flaviae sp. nov.differs from  K. crassiflagellatain the broader pterostigma (PtL/PtW <9.0 versus> 14.0), and from  K. setinervisin the much shorter setae on head, thorax and forewing veins; the longer vertex relative to the width; the narrower pterostigma (PtL/PtW> 7.0 versus <7.0), and longer (Cu 1aL/FL> 0.3 versus <0.3) and narrower (Cu 1aL/cu 1W> 3.0 versus <2.0) cell cu 1; and the oval female circumanal ring.   Klyveria flaviae sp. nov.differs from the fossil species K. succinaBurckhardt & Drohojowska described from Dominican amber ( Burckhardt et al.2024a) in the smaller body size (HW <0.5 vs. = 0.6; FL <1.4 versus = 1.5; MT <0.4 vs. = 0.5), more elongate forewing with the cell c+sc narrow (vs. broad), vein M longer than M 1+2(vs. shorter), vein Cu longer than Cu 1b(vs. shorter) and cell cu 1broader (vs. narrower). 5132507658 2012-11-14 UFPR Brazil 470 -19.033 South of Rio Verde 7 -54.8583 Rio Verde 34 35 1 1 Mato Grosso do Sul holotype 6163506312 [199,1212,331,358] UFPR Brazil MATO GROSSO DO SUL 34 35 21 10 11 Mato Grosso do Sul paratype 6163506353 NHMB Brazil MATO GROSSO DO SUL 34 35 21 10 11 Mato Grosso do Sul paratype 5132507609 2012-11-16 NHMB Brazil 450 -20.8907 Campo Grande 7 -54.5713 34 35 1 1 Mato Grosso do Sul paratype 6163506324 2012-11-18 2012-11-20 2012-11-18 MMBC Brazil 440 -21.4494 Jardim 7 -55.7919 34 35 16 7 9 Mato Grosso do Sul paratype 6163506331 [348,439,512,538] 2012-11-18 2012-11-20 2012-11-18 NHMB Brazil 440 -21.4494 Jardim 7 -55.7919 34 35 16 7 9 Mato Grosso do Sul paratype 6163506309 2012-11-18 2012-11-20 2012-11-18 UFPR Brazil 440 -21.4494 Jardim 7 -55.7919 34 35 16 7 9 Mato Grosso do Sul paratype 5132507371 2012-11-15 NHMB Brazil 350 -19.9683 Rochedo 7 -54.65 34 35 2 2 Mato Grosso do Sul paratype 5132507586 2012-11-17 NHMB Brazil 440 -21.0789 South of Sidrolandia 7 -54.956 Sidrolandia 34 35 7 6 1 Mato Grosso do Sul paratype 5132507525 2010-06-01 2010-06-06 2010-06-01 NHMB D.
