Janáklgt. (cJan).   Remarks. Originally described from Madagascar, this is the only macropterous  Pseudolathraknown from Réunionso far. Male sternite VII ( Fig. 4) is normally pubescent, lacking modified setae, similar to  P. hamonibut with sparser pubescence particularly in the middle of posterior margin. The excision of the posterior margin of male sternite VIII ( Fig. 20) is relatively deeper than in  P. hamoni. The aedeagus ( Figs 1–3) is characterised by two long processes attached to an asymmetrical apical portion of the ventral process of the aedeagus, a unique feature among Madagascan  Pseudolathra. Habitus photos of this species were published by Janák (2014).   Distribution. Madagascar, Réunion. 2116191721 1991-12-29 1992-01-01 1991-12-29 J. Janak Réunion St. Paul - Grand Etang 1 438 12 2 4
