Parastasia fruhstorferi Ohaus, 1902: 57 View in CoL [original description; synonym of Parastasia indica View in CoL by Ohaus (1905: 97)].

Remarks and distribution. The species exhibits two distinct color morphs: a blackish variant, observed in India, Southwest China, Laos, and North Thailand, and a reddish variant, found from Southeast China to North Vietnam ( Kuijten 1992; Zhao 2019). In Thailand, the species has been documented in the provinces of Nan and Chiang Mai ( Wada 2015), with an intriguing discovery of additional blackish specimens found in a decaying log in Phetchabun Province, Central Thailand (Fig. 46).

Parastasia alternata Arrow, 1899 View in CoL ; Ek-Amnuay, 2008: 192 (misidentification).

Material examined: Thailand: Chiang Rai Prov., Wiang Pa Pao Dist., Khun Lao , R. Pornvannapet leg., 28.V.2019, 2♂♂ ( CTH) .

Remarks and distribution. Parastasia alternata Arrow, 1899 was locally recorded from Wiang Pa Pao by Ek-Amnuay (2008). However, it has been noted that this species is restricted to the Himalayan Region ( Kuijten 1992; Zorn & Bezděk 2016; Zhao 2019). The diagnosis and recorded locality of P. alternata in Thailand differ from the specimens in those of earlier studies. Based on the locality, the recorded species may actually be P. masumotoi , which is endemic to Thailand. Additionally, the specimens used in this study were collected during the day.
