Peltariosilis mitarakaemontis Constantin, 2017: 63 .

Type material examined: PARATYPE ♂ (CCo): “ Guyane fr., massif Mitaraka / camp DZ, light trap / 26.II. 2015, alt. 310 m / 2˚14′4″N - 54˚27′2″W / J.Touroult,E. Poirier,J.H.Yvinec // La Planète Revisitée-MNHN / PNI Guyane 2015-APA-973-1 /collecte, tri & préparation / Société entomologique Antilles-Guyane // PARATYPE / Peltariosilis / mitarakaemontis / Constantin i.l. / R. Constantin des. 2016”.

Diagnosis: Head black, antennae brown, except antennomeres I-III and X light brown, XI yellow, pronotum and scutellum orangish, elytra dark brown, legs yellow. Male ( Fig. 7B View Figure 7 ): Antennae long, antennomeres IV-XI slender, not swollen,slightly wider at apex.Pronotum ( Fig.10N View Figure 10 ):anterior margin broadly arched; frontolateral lobes small, not strongly projected; sides behind frontolateral lobe nearly straight, slightly convergent; laterobasal lobe robust, projected dorsally,not strongly curved,dorsal flap broad, apex rounded; dorsal projections very small, forming a weak angulate protuberance meeting laterobasal lobe laterally. Scutellum ( Fig. 12N View Figure 12 ) with very slender lamellar projection,narrower near base and slightly wider distally, apices slightly projected, not forming well-defined fork. Peltariosilis mitarakaemontis is similar to P.parviscutellaris sp. nov. and P. brunneoapicalis sp. nov. by the shape of scutellar projection not forming distinct fork. It differs from these species by the uniform dark brown colouration of elytra, and by pronotum with very small dorsal projection and laterobasal lobes not strongly curved.

Distribution: French Guiana ( Fig. 18 View Figure 18 ).
