Macroscelesia vietnamica Arita & Gorbunov, 2000

( Figs 5, 6, 8 , 12 )

Material examined. 4 ♂, Guangdon Prov., Shaoguang , Nanling , 800 m, 22.–23.vi.2008 ( Figs 5, 8 , NSMT, CAK) ; 1 ♂, same locality, 6.ix.2005, leg. Xiong Wei ( SCAU) ; 1 ♀, same locality, (Gen. prep. AK770, Figs 6 , 12 , CAK) ; 1 ♂, Guangxi Prov., Guilin, Maoershan , 730 m, 16.viii.2009 ( NSMT) ; 1 ♂, Hunan, Changsha, Liuyang, Daweishan , 360 m, 30.vii.2011 ( NSMT) .

M. vietnamica was known from only a single female collected in northern Vietnam. It is here recorded from China and the male is figured for the first time. Furthermore, we extend the diagnosis given in the original description to cover the male specimens, and compare it specifically to M. japona and M. perlucida , which occur in the same region. The morphology of the female genitalia of the specimen examined from Nanling ( Fig. 12 ) is very similar to that of the holotype from Vietnam ( Arita & Gorbunov 2000). The form of the bursa copulatrix and the sclerotized area around the ostium is diagnostic and differs from that of M. japona ( Fig. 11 ).

Diagnosis. ETA large but consisting of only 5 transparent cells, with cell between Cu1 and Cu2 opaque (ETA smaller in M. japona , cell between Cu1 and Cu2 transparent in M. perlucida ); discal spot relatively narrow and straight (wider and with a convex outer margin in M. japona and M. perlucida ); with relatively long projection into the ATA (shorter in in M. perlucida ); abdomen ventrally bright white (creme to pale ochre in M. perlucida ); basal 1/3 of hind tibia ventrally white (basal ½ of hind tibia crème to pale ochre in M. perlucida ) and hind tibial tuft black with some white and reddish scales (black with some white and ochre yellow scales in M. perlucida ).
