Redescription

The species has been recently redescribed and diagnosed in detail by Smetana (2017a) under the name I. bicoloris . This description is supplemented here only by the comments above and Figs 1D–E, 7B.

Distribution

This widespread, potentially common species is known from medium elevations in northern Myanmar, and Yunnan and Sichuan, China (Smetana 2017 a, 2017b).

Bionomics

Indoquedius parallelicollis appears to be tolerant to human disturbance and has been collected in a haystack and plant debris in a ruderal habitat (Smetana 2014, 2017a; Yan et al. 2017). Other specimens have been collected in a mixed forest by sifting litter, twigs and roots (Smetana 2015)

Remarks

The type series of I. parallelicollis includes one male and one female (Fig. 1D). The male was dissected to reveal an aedeagus identical to the color polymorphic species I. bicoloris . The current distribution of I. bicoloris includes the narrow part of Yunnan, China, west of the Salween River (Smetana 2014) and not far from Kambaiti Pass in Myanmar. Therefore I. bicoloris syn. nov., becomes a junior synonym of I. parallelicollis .

The female holotype of I. sanguinipennis (Fig. 1E) corresponds perfectly (coloration of legs and abdomen, elytral punctation) with a female paratype (ASC) of the red elytra morph of I. bicoloris . Female tergite X was also consistent with that of I. bicoloris and the paratype of I. parallelicollis, including the deep emargination (Fig. 7B). Therefore, along with I. bicoloris, I. sanguinipennis syn. nov., becomes a junior synonym of I. paralellicollis .
