Treatment

Peltariosilis mensaemontis Constantin, 2017 ( Figs. 5C View Figure 5 , 10C View Figure 10 , 12C View Figure 12 )

Peltariosilis mensaemontis Constantin, 2017: 62 .

Type material examined: PARATYPE ♂ (CCo): “ Guyane FranÇaise /MontTabulaire-Itoupé/3˚01′19″N-53˚05′03″w / alt. 800m,auto’LT PinkLED / 25.XI.2014, SEAG & Dalens // PARATYPE / Peltariosilis / mensaemontis / Constantin i.l. / R. Constantin des. 2016”.

Diagnosis: Head and antennae black, ventral face of antennomere I-II yellow to light brown,pronotum orangish, scutellum reddish, elytra black, legs yellow, apical two thirds of tibiae and four basal tarsomeres brown. Male ( Fig. 5C View Figure 5 ): Antennae long, antennomeres IV-VIII swollen, subcylindrical, IX-XI slender, narrower than preceding ones. Pronotum ( Fig. 10C View Figure 10 ): anterior margin strongly arched, broadly continuous with frontolateral lobes; sides behind frontolateral lobe concave; laterobasal lobe with dorsal flap broad, apex truncate; dorsal projections broad, divergent, distal margin rounded, directed posterolaterally. Scutellum ( Fig. 12C View Figure 12 ) with vertical trapezoidal lamellar projection, slightly longer than wide at base. Peltariosilis mensaemontis differ from P.guyanensis by the dorsal flap of laterobasal lobe of pronotum broad, truncate at apex.
