Systematics of the American Katydids (Orthoptera: Tettigoniidae).
Communication 12: the subtribes Steirodontina and Anaulacomerina
ABSTRACT
A new material on the genera Steirodon Serville, 1831, Cnemidophyllum Rehn, 1917, Emsleyfolium Cadena-
Castañeda et al., 2016 and Stilpnochlora Stål, 1873 from the subtribe Steirodontina (Steirodontini) as well as on
the genera Separatula Gorochov, 2018 and Anaulacomera Stål, 1873, belonging to the subtribe Anaulacomerina
(Phaneropterini), is considered. Some subgenera of these genera and their diagnostic characters are brief-
ly discussed. The following new taxa (13) are described: Steirodon (Steirodon) superbum sp. nov. from Peru;
S. (Peucestes) para sp. nov. from Brazil; S. (P.) dentatum woronovi subsp. nov. from Colombia; S. (Posidippus) mi-
nor sp. nov. from French Guiana; S. (Frontinus) planifemur sp. nov. from Peru; Cnemidophyllum (Peucestophyllum)
granti peruanum subsp. nov. from Peru; C. (Peucestoides) bituberculatum sp. nov. from Peru; Emsleyfolium uni-
lobatum sp. nov. from Peru; E. cusco sp. nov. from Peru; Stilpnochlora jalisco sp. nov. from Mexico; S. marginel-
la latistriata subsp. nov. from Surinam; Separatula symmetrica sp. nov. from Peru; S. falcata tenuis subsp. nov.
from Peru. Steirodon validum Stål, 1874 and S. (Posidippum) parastahli Piza, 1979 are returned in the subgenera
Steirodon and Posidippus Brunner-Wattenwyl, 1878, respectively (but the latter species as a possible synonym
of S. stahli Brunner-Wattenwyl, 1878); the generic names Phyllolophus Rehn, 1944 and Steirodonopis Scudder,
1875 are returned in synonyms of the subgenera Steirodon and Frontinus Stål, 1873, also respectively. For the
homonymic name Posidippus validus Saussure et Pictet, 1898, the new name S. (Posidippus) major nom. nov.
is established, and S. (P.) dentiferoides Emsley, 1970, syn. nov. is synonymized with S. (P.) stahli. For Steirodon
(Frontinus) irregulariterdentatum (Brunner-Wattenwyl, 1891), the neotype is designated, and this species is rede-
scribed; Posidippus rarospinulosus Brunner-Wattenwyl, 1891 is transferred to Steirodon (Frontinus), and P. trice-
narius Piza, 1974 is treated as a separate species in the same subgenus but not as a synonym of S. (F.) rufolineatum
Emsley, 1970. Cnemidophyllum (Cnemidophyllum) tani Cadena-Castañeda, 2016 is transferred to the subgenus
Peucestophyllum Emsley, 1970 of the same genus. For A. (Munticercora) sclerogenitalis woronovi Gorochov, 2021,
the male cerci are firstly described.
