Mesopodagrion tibetanum McLachlan, 1896

Remarks. As discussed in the introduction, the male and female syntypes of Mesopodagrion tibetanum in BMNH represent two different species. In order to preserve current usage of the name we here designate the syntype male as lectotype. We have informed the curator of the Odonata collection, David Goodger, of this and have asked him to apply the following lectotype label to the male: " Mesopodagrion tibetanum McLachlan, 1896 / LECTOTYPE des. Xin Yu & Wenjun Bu, 2009." The lectotype male is the type species for Mesopodagrion and its type locality is Moupin, now in Sichuan province, China. Curiously, Kimmins (1970) did not list this species in his type catalog. Fraser's (1933) account should apply to Mesopodagrion tibetanum but Fraser neglected to illustrate or discuss the unique bifurcate process although cerci and genital ligula were correctly figured. None of our specimens was consistent with the wing vein pattern illustrated by Fraser (1933), i.e. ‘two rows of cells between Cuii and IA near their terminations’. His supposition that pale color on living male was blue was correct based on our field work. This species usually has pruinosity onS9–10. Based on distinct differences between populations from Sichuan and Yunnan we have divided them into two subspecies as follows.
