Diagnosis: Antennae entirely pale yellow; pronotum and scutellum orange yellow; elytra dark brown, slightly lighter at lateral margins. Antennomeres X-XI slightly narrower than preceding ones, middle antennomeres not distinctly swollen. Pronotum with low, sharp dorsal projections; laterobasal lobes curved, directed dorsally and posteriorly, apex rounded, divided in two flaps. Scutellum with a long, forked projection; apices acute, divergent, pointing latero-anteriorly. Peltariosilis flavicornis sp. nov. is similar to P. gracilicornis sp. nov. by the entirely pale yellow antennae. They differ by the scutellar projection much narrower at middle in P.flavicornis sp. nov.
Description: Head black, except anterior margin of clypeus, dark brown; antennae, labium, maxillae, palpi and
base of mandibles pale yellow, apex of mandibles light brown; pronotum and scutellum orange brown, slightly translucent; elytra dark brown, lighter at lateral margins; legs entirely testaceous yellow to light orange yellow; thorax and abdomen dark brown.
Male: ( Fig. 6C View Figure 6 ): Antennae rather long; antennomere I elongate, slightly wider apically, II short, slightly wid- er apically, III-IX nearly oblong, narrower proximally, not distinctly swollen, slightly flattened dorsoventrally, IX-XI narrower, slender. Anterior margin of clypeus with a broad arcuate concave notch. Pronotum ( Fig. 10I View Figure 10 ): anterior margin broadly arched; frontolateral lobe narrow, projected laterally, sides behind frontolateral lobe slightly convergent; angles of laterobasal indistinct; laterobasal lobe curved, directed posteriorly and dorsally, apex rounded, split, forming juxtaposed dorsal and ventral flaps; apex of ventral flap with a short membranous projection; dorsal projections low, transverse, directed postero-dorsally, distal margin dull, forming an inner obtuse peak and acute lateral peaks barely reaching sides of pronotum. Scutellum ( Fig. 12I View Figure 12 ) with a long Y-shaped forked projection anteriorly; scutellar projection strongly narrowed at middle, elongate and broadly widened, forming apical fork with divergent apices; apices of fork acute, pointing latero-anteriorly. Elytra nearly parallel, apex rather truncate. Abdominal tergite VIII ( Fig. 13F View Figure 13 ) subquadrate, nearly as long as wide, lateral margins sinuous, wider medially; glandular pores slightly protruding; distal margin with a shallow rounded median notch. Ventrite VII ( Fig. 14F) wide, lateral margins sinuous, wider anteriorly and much narrower posteriorly, apex narrowly rounded near middle;internal margins nearly straight,divergent, halves broadly separated. Aedeagus ( Fig. 16 View Figure 16 I-L): ventral plaque of tegmen lateroventral, elongated, nearly as long as internal sac, shorter than sclerites, flattened laterally, straight, apex sickle like, broadly curved dor- sally; parameres fused at base, parallel, broadly arched dorsally, apex acute; median lobe tubular, membranous, translucent; internal sac elongated, narrow, straight, weakly sclerotised; one single median dorsal sclerite, elongated, narrow, apex acute; paramedian dorsal sclerites robust, strongly sclerotised, elongated, straight with apex curved dorsally, rough, scratched; ventral sclerites slender, as long as internal sac, apex acute, slightly divergent; lateral sclerites indistinct or absent.
Female: General appearance and colouration similar to males, antennae thinner and shorter than in male, middle segments not thickened. Eyes smaller and less protruding. Pronotum as in ( Fig. 11B View Figure 11 ).
Etymology: The specific epithet flavicornis is formed from the Latin words flavus (yellow) + cornis (“horn”, antenna), referring to the yellow antennae.
Distribution: Bolivia and Brazil (Amazonas and Mato Grosso states) ( Fig. 18 View Figure 18 ).
