Lathrobium (Madecalobrathium) keiseri Scheerpeltz, 1961 : 251 ( type locality: Madagascar , Soanierana-Ivongo). Pseudolathra keiseri : Janák, 2014 : 475 . Pseudolathra (Madecalobrathium) keiseri : Lecoq, 2017 : 207 . Material studied . 6 specimens ( 4♂♂ , 2♀♀ ): Réunion , St. Paul – Grand Étang , 29.12.1991 – 1.1.1992 , J. Janák lgt. (cJan) . Remarks . Originally described from Madagascar , this is the only macropterous Pseudolathra known from Réunion so far. Male sternite VII ( Fig. 4 ) is normally pubescent, lacking modified setae, similar to P. hamoni but 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 .
