Abstract: Both Metrodorinae and Cladonotinae are polyphyletic subfamilies of Tetrigidae
and are thus in need of revision. This paper offers a key step toward this by
defining the nominotypical tribe of Metrodorinae, Metrodorini Bolívar,
1887 that encompasses mostly apterous species with arcuate median carina of
pronotum, laterally projecting lateral lobes of pronotum, and produced carinae
of vertex forming horns. The tribe Metrodorini consists of the following genera:
Cota Bolívar, 1887; Hancockiella Cadena-Castañeda & Cardona, 2015;
Metrodora Bolívar, 1887; Miriatra Bolívar, 1906; Antillotettix Perez-Gelabert,
2003; Armasius Perez-Gelabert & Yong, 2014; †Baeotettix Heads, 2009;
Bahorucotettix Perez-Gelabert, Hierro & Otte, 1998; Cubanotettix
Perez-Gelabert, Hierro & Otte, 1998; Cubonotus Perez-Gelabert, Hierro &
Otte, 1998; †Electrotettix Heads & Thomas, 2014; Haitianotettix
Perez-Gelabert, Hierro & Otte, 1998; Hottettix Perez-Gelabert, Hierro &
Otte, 1998; Mucrotettix Perez-Gelabert, Hierro & Otte, 1998; Sierratettix
Perez-Gelabert, Hierro & Otte, 1998; Tiburonotus Perez-Gelabert, Hierro
& Otte, 1998; and Truncotettix Perez-Gelabert, Hierro & Otte, 1998. The
following new synonyms are recognized: Metrodorini = Miriatrini
Cadena-Castañeda & Cardona, 2015, syn. nov. = Mucrotettigini
Cadena-Castañeda & Silva, 2019, syn. nov. Eleleus curtus Bolívar, 1887 is
excluded from Metrodorini and is left under Cladonotinae without tribal
assignment. Biogeography, evolution, and taxonomies of Metrodorinae and
Cladonotinae are briefly discussed.
