From top to bottom: 1-Chorthippus dorsatus, female;
2, 5 - Chorthippus from the biguttulus group, female;
3 - Chorthippus (=Pseudochorthippus) parallelus, female;
4 - Chorthippus apricarius, male;
6 - Tettigonia viridissima, female;
7-Phaneroptera falcata, female.

As for the generic name Pseudochorthippus: firstly, I am not sure that it is valid at all due to the rather peculiar diagnosis of the genus in the original description (the place on the cladogram obtained as a result of analyzing the sequence of some mitochondrial genes is still not a sign); secondly, there are doubts about the correctness of the attributes attributed to this function. a group of phylogenetic relationships. Defoe didn't just throw her out of the hortippus, but brought her closer to the grasslands, which is not consistent with morphology. In addition, as I understand it, as long as molecular taxonomists have an idea of "bad" and "good" genes (mitochondrial genes, by the way, are "bad") - and until they explain to me how (and, most importantly, by what mechanisms) some differ from others, I am "molecular" systems I'm not going to believe it.

And more about paralleluses. Color as in the photo from Zhukovsky is quite common in individuals from Adygea, and in the North-West of Russia it is also found, but rarely. In general, I have an underlying suspicion that parallelus may be a complex of allopatric twin species - it would be necessary to look at stridulation spines.
