Vertex conical and relatively short, without expansion. Pronotal disc with a pattern of callose stripes. Hind femora and tibiae with curved and elongated spines. Tegmina with undulate contour ( Fig. 16A ). Male cerci flattened and ribbon-like with an elongated or abruptly pointed tip, lobe or inner branch sub-triangular or spineshaped ( Figs. 16B–J ). Ovipositor long, curving slightly upward, with the apical region slightly serrulate. Tips of upper and lower valve rounded ( Fig. 16F ). Type species. Phaneroptera phyllacantha Burmeister, 1838 , by subsequent designation. Distribution. Along the Atlantic coast of Brazil , Mata Atlântica and Araucaria angustifolia forest ( Map 2 ). Map 1.

Main lobe of male cercus elongated and curving weakly at apical half, accessory lobe longer than wide................. 2 - Main lobe of male cercus elongated and curving abruptly at apical two-thirds ( Fig. 16B,C ), accessory lobe as long as wide......................................................................... M. itatiaia Antunes & Tikiya, 2020 2. Male cerci elongated, slightly curving upward, inner margin concave with a slight crest-like prolongation from base to tip, distal portion rounded with a small, pointed projection on the dorso-apical margin ( Fig. 16D, E ).................................................................................................. M. phyllacantha ( Burmeister, 1838 ) - Male cerci elongated but not curving upward, inner margin concave with uniform basal region, without inner prolongations and narrow tip; male cerci armed at the internal base with a spine-like, internally projecting process....................... 2 3. Vertex process more evident, short and conical; male cerci shorter and somewhat more robust, main branch moderately sigmoid and distally not strongly falcate, ventro-internal margin with several spaced nodes ( Fig. 16G–H )... M. scalprum Rehn, 1950 - Vertex process less evident, rectangular in lateral view; male cerci longer and overall thinner, main branch hardly sigmoid, distal two-fifths sharply bent and falcate, ventro-internal margin without spaced nodes ( Fig. 16I–J )...................................................................................................
