Systematics of the American Katydids (Orthoptera: Tettigoniidae). Communication 3

Abstract

New data on Phaneropterinae from Ecuador, French Guiana, Peru and Bolivia are given. Vellea pulchra sp. nov., Euceraia umbrosa sp. nov., E. subaquila colorata subsp. nov., E. cercata sp. nov., E. cercata elchaco subsp. nov., E. convoluta sp. nov., E. proxima sp. nov., E. abnormalis parallela subsp. nov., E. varia sp. nov., E. varia simulata subsp. nov., E. gusarovi sp. nov., Pycnopalpa porphyretica sp. nov., P. occidentalis sp. nov., P. gracilenta sp. nov., Hetaira angusta sp. nov. and H. morona sp. nov. are described. New subgenera of the genus Pycnopalpa Audinet-Serville, 1838 (Vitrosoria subgen. nov. and Gracisoria subgen. nov.) are established. Euceraia sanguinea Piza, 1950, sp. dist. and Zenirella Piza, 1973, gen. dist. are restored from synonymy. Zenirella punctata (Brunner-Wattenwyl, 1878), comb. nov. and H. aurigera (Rehn, 1918), comb. nov. are transferred from the genera Ligocatinus Rehn, 1901 and Topana Walker, 1869 to Zenirella and Hetaira Brunner-Wattenwyl, 1891, respectively. Two former genera are included in the genera Hetaira and Gnathoclita Hagenbach, 1841 (Pleminiinae) as their subgenera Atopana Vignon, 1930, stat. nov. and Disceratus Scudder, 1869, stat. nov. (= Tettohenicus Gorochov, 2012, syn. nov.), respectively. Some new data on species distribution are given.

“…Female. Coloration and structure of body in above-mentioned females almost indistinguished from those in holotype collected in same department of Peru (Gorochov 2014). However, coloration of these specimens somewhat variable: sternites and genital plate from almost yellowish to light brown, and ovipositor from almost uniformly light brown to more or less yellowish with brown areas at base and light brown dorsal and ventral stripes.…”

“…This communication is the eleventh one in the series of my publications on the American Tettigoniidae. It continues the first, second, third, fifth, ninth and tenth communications (Gorochov 2012a(Gorochov , 2012b(Gorochov , 2014(Gorochov , 2015(Gorochov , 2020(Gorochov , 2021 containing some results of the taxonomical study of the genera Lichenomorphus Cadena-Castañeda, 2011, Dissonulichen Cadena-Castañeda, 2011, Theia Brunner-Wattenwyl, 1891, Hetaira Brunner-Wattenwyl, 1891and Anaulacomera Stål, 1873. In this paper, additional data on these genera, including descriptions of new species and subspecies, are presented.…”

“…I consider it as a genus with three subgenera and include this genus in the subtribe Pycnopalpina Cadena-Castañeda, 2014 (Gorochov 2015), but in OSF, this genus is treated as the separate subtribe Theina Cadena-Castañeda, 2014 divided into four very closely related genera. However, my subgeneric classifications of the genera Hetaira and Anaulacomera (Gorochov 2014(Gorochov , 2020(Gorochov , 2021 are supported in OSF, that is somewhat illogically, because differences between subgenera in these genera and in Theia s. l. are of the same level (in Anaulacomera s. l., subgeneric differences are sometimes even more significant).…”

“…Males from the type locality and Cusco Department are slightly different and may belong to different subspecies, but at present it is impossible to understand their variability (only two males and one female from Peru as well as one male from Colombia are known). Moreover, the original description of the epiproct in the male holotype (Gorochov 2014) is erroneous. This male was probably collected shortly after moulting, and its last tergite was strongly deformed on drying: this tergite acquired two false folds, and its posterior edge became indistinct.…”

“…53); epiproct large, with strongly widened and rounded dorsolateral (anterolateral) lobes covering parts of last tergite and of cercal bases (Fig. 53); cerci arcuate but with distal parts less curved medially than in males determined by me (Gorochov 2014) as H. (H.) ?smaragdina (compare Figs 49 and 52); genital plate somewhat shorter than in these males and with three small but distinct apical lobules (median lobule very small, clearly shorter than lateral ones; Fig. 51); genitalia membranous.…”
