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 .
