Coronophyllum, Mendes & Sobral & Neto, 2023

Mendes, Diego Matheus De Mello, Sobral, Rafael & Neto, Alberto Moreira Da Silva, 2023, New genus of Steirodontini Brunner von Wattenwyl, 1878 (Orthoptera: Tettigoniidae: Phaneropterinae) from the Brazilian Amazon Rainforest, Zootaxa 5389 (1), pp. 128-134 : 130

Coronophyllum gen. nov.

Figures 1–5

Diagnosis. Pronotal disc dorsolaterally with large row of long spines anteriorly directed forward and posteriorly directed backwards, in lateral view ( Fig. 2A, C–D ). Tegmina with main branch of Vein R black; presence of small black spots asymmetrical in rows at anterior and posterior margins of tegmina; black spots parallel to main branches of veins R, M and Cu ( Figs. 2A and 3 ).

Additional taxonomic notes. Coronophyllum gen. nov. is very unique compared to other genera of Steirodontini due to the morphology of pronotal spines and the pattern of spots on tegmina. Phylogenetic studies are needed to elucidate the relationships of this genus within the tribe.

Etymology. From Latin word Corono = crown + phyllum = leaf, meaning crown leaf. In reference to the striking row of spines on the pronotum that resembles a crown, neutral gender.

Distribution. Brazil: Amazonas.

Included species.

Coronophyllum catarinae sp. nov. ♂ (type species).
