Distribution: China: Henan (holotype), Gansu, Hebei, Sichuan. Records from Gansu and Sichuan need to confirm, and these were not cited by Bian et al. 2021.

The morphological features of the specimens from Liaoning ( Figs. 1–9 View FIGURES 1–2 View FIGURES 3–9 ) is completely consistent with those described by Liu and Wang (1998). Moreover, four records from different localities of Liaoning provide strong evidence for its natural distribution ( Fig. 10 View FIGURE 10 ). These records indicate that this species emerges as adults in June, July and August, which is similar to other records from Beijing, Henan and Hebei ( Liu & Wang 1998, Li et al. 2014, iNaturalist 2023). In Japan, N. testaceus overwinters as nymph stage ( Ichikawa et al. 2006). Whether P. unicolor overwinters as nymph stage is unknown and more observations are needed.

Loss of wings occurs in many insect groups ( Roff 1990; Wagner & Liebherr 1992). In Japan, N. testaceus is apterous occurring as north as Hokkaido, and Eugryllacris japonica (Matsumura & Shiraki 1908) is macropterous occurring as north as Honshu. In Korea, E. japonica is only distributed in south area, such as Chungcheongnam-do, Jeollanam-do, Gyeongsangnam-do and Jeju-do ( Kim et al. 2014; Storozhenko et al. 2015), while N. testaceus can be found in north areas. In North America, C. carolinensis is apterous occurring as north as Point Pelee National Park, while Brachybaenus studti (Griffini, 1911) is macropterous occurring as north as central Mexico (iNaturalist 2023, photo#25301207). It seems that macropterous gryllacridid individuals do not occur as far north in some areas as do apterous gryllacridids. In China, P. unicolor possesses wings and occurs as north as Liaoning. However, Chinese apterous species, such as Apterolarnaca (Bianigryllacris) biloba (Liu, Bi & Zhang, 2010) and Melaneremus laticeps (Karny, 1926) , only are known as far north as Tianmu Mountain in southeastern China ( Bian et al. 2021). Moreover, other northern species in China are all relatives of P. unicolor , such as P. laoshanica Yin, Wang & Shen, 2021 and P. sheni Niu & Shi, 1999 . All their life cycles are still unknown. Their special overwintering biology seems well worth researching.
