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 &amp; 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.</p></div>	https://treatment.plazi.org/id/340A1223FFAED97BFF6BF942E6F3FE2C	Public Domain	No known copyright restrictions apply.

This subspecies is believed by V. Kalkman (pers. com.) to occur in Kangding, Sichuan and Deqen, Yunnan, China. This species occurs at higher elevations (&gt; 3000m) compared to M. yachowensis (Fig. 7).</p></div>	https://treatment.plazi.org/id/340A1223FFA9D970FF6BF941E6F9FE76	Public Domain	No known copyright restrictions apply.

Antehumeral stripe excavated at upper fourth and with small anteriorly directed offshoot (Fig. 4 a). S10 pale dorsally (Fig. 5 a); basal half of cerci distinctly dilated, almost twice as wide as abruptly narrowed distal half (Figs. 5 a, 8–10); bifurcate process short, not longer than 1/2 width of S10, outer margin concave, hemline of bifurcate process less than 1/3 width of S10 (Figs. 8–10). Apical lobs of genital ligula bifurcate at base (Fig. 1, d &amp; e).</p><p>Female. Similar to male in color pattern but slightly shorter in body length and more robust (Fig. 1 c). Antehumeral stripes broader than in male. Terminus of abdomen similar to female of M. t. tibetanum except ovipositor shorter, ending at about level of end of S10 (Fig. 6 a).</p><p>Remarks. Acknowledging the inaccuracy of illustrations of M. tibetanum by Fraser (1933), Chao (1987) later synonymized his own species with M. tibetanum . We doubt that Chao had seen the syntype male of M. tibetanum or had a specimen of true M. tibetanum, otherwise he would seen the distinct differences between these two species. We concur with Kalkman (2008) in treating M. yachowensis as a separate species.</p><p>Distribution. A more northerly species than M. tibetanum species occurring in mountainous areas along a largely east-west arc from central Sichuan (apparently sympatric with M. tibetanum there), Gansu north to Henan and east to Zhejiang provinces. This species occurs at lower elevations from about 1400m (Tianmu), to about 3000m (Qinling, Fig. 7). We have been unable, despite intensive search, to locate Siao-lou [Xiaolou] for McLachlan's female in Sichuan Province.</p></div>	https://treatment.plazi.org/id/340A1223FFA4D970FF6BFE5DE517F8A7	Public Domain	No known copyright restrictions apply.
