Rhodoprasina winbrechlini Brechlin, 1996. in Kitching & Brechlin, 1996, Nachr. entomol. Ver. Apollo (N.F.) 17(1): 59. Type locality: Vietnam (north), Lao Cai Province, Mt. Fan-si-pan (north side), Sa Pa, 22°17'N, 103°44'E, 1600m.
Males with characteristically long antennae, which extend beyond the forewing discal spot, a feature it shares with R. corolla Cadiou & Kitching, 1990. Green of forewing with a faint blue tint. Red of hindwing upperside not extending beyond the median line, with the distal half of the wing being greenish.
In northern Vietnam this species flies in primary woodland at 1600m altitude at quite low temperatures (12-4°C). Unlike R. corolla and R. corrigenda, R. winbrechlini appears to be a cold season species, the adults flying when night-time temperatures fall below 10°C (Kitching & Brechlin, 1996).
China: 5.iv (Yunnan).
In northern Vietnam in early March. The later flight-time in Yunnan (early April) may be due to the higher altitude.
OVUM: Unknown.
