Material examined
A total of 6 specimens (4 males and 2 females, including 4 males and 1 female in cBL&KB and ZIN and 1 male in cFED) were examined from the following localities: China. Yunnan. Longxiang County (District): 1 male, ENE Lincang, 23°57'36"N, 100°15'21"E, 3340 m, 28.VI.2011, I. Belousov, I. Kabak & A. Korolev leg. (ZIN). Shuangjiang County: 3 males, SSE Shuangjiang Town, 23°22'32"N, 99°53'47"E – 23°22'22"N, 99°53'26"E, 2790-2950 m, 23.VI.2011, I. Belousov, I. Kabak & A. Korolev leg. (cBL&KB, ZIN). Vietnam. Lao Cai Province. 1 female, 6 km W of Sa Pa, N slope of Phansipan Mt. Area, 2000–2100 m, near Tram don (base of Hoang Lien Nat. Park), 22°21'N, 103°46'E, V.2005, A.V. Abramov leg. (Exp. of Russia-Vietnam Tropical Centre) (ZIN); 1 male, Sa Pa env., ca 1600 m, V.2006, A. Anitchkin leg. (cFED).
Distribution
Previously, Chydaeus bedeli vietnamensis was known from a single male collected in northern Vietnam (type locality: northern slope of Fansipan Mt., Sa Pa, 22°17'N, 103°44'E, 1525 m). Based on the new records reported here, this subspecies occurs also in southern Yunnan Province, China (Fig. 62).
Remarks
Specimens from Yunnan are similar in external features and male genitalia to those from Vietnam, but they are slightly smaller (body length 9.0-10.2 mm versus 10.7–10.8 mm in males from Vietnam, including the holotype) and have more markedly prominent denticles at their basal pronotal angles. We add the following mensural data to describe the Yunnan specimens and thereby expand on Kataev & Schmidt’s description of this taxon: Proportions (males from Yunnan): HWmax/PWmax = 0.71–0.72; HWmin/PWmax = 0.59–0.61; PWmax/PL = 1.52–1.59; PWmax/PWmin = 1.26–1.37; EL/EW = 1.34–1.44, EL/PL = 2.62–2.85, EW/PWmax = 1.23–1.28.
