Peltariosilis lamellata Constantin, 2017: 61 .

Type material examined: PARATYPE ♂ (CCo): “ Guyane fr., massif Mitaraka / sommet en cloche; savane roche / 20.VIII.2015, auto-LTgemlight / 2˚13′41″N - 54˚28′5″W- 310 m / P.Dalens,S.Brûlé,E.Poirier,F.Robin // La Planète Revisitée-MNHN / PNI Guyane 2015-APA-973-1 /collecte, tri & préparation / Société entomologique Antilles- Guyane // Paratype pelt./ lamellata / Paratype / lamellata”. Diagnosis: Head and antennae black, except for antennomere I and ventral face of II, pronotum orangish, scutellum reddish, legs orangish yellow, distal half of tibiae and four basal tarsomeres infuscate. Male ( Fig. 5D ): Antennae long, antennomeres V-VIII swollen, ovoid, IX-XI slender, narrower than preceding ones. Pronotum ( Fig. 10D ): anterior margin arched, broadly continuous with frontolateral lobes; sides behind frontolateral lobe concave; laterobasal lobe not projected laterally, curved posteriorly; angles of laterobasal lobe forming long, acute spikes; dorsal projections broad, distal margin rounded, directed dorsally. Scutellum ( Fig. 12D ) with vertical trapezoidal lamellar projection, as long as wide at base, apex truncate. Peltariosilis lamellata differ from P. amapaensis by the angles of laterobasal lobes of pronotum forming long, slightly curved spikes, and dorsal projection shorter, posterior margin rounded, directed dorsally.

Distribution: French Guiana ( Fig. 18 ).
