GRYNE MARMORATA ( ROEWER, 1915) COMB. NOV.

( FIGS 48 , 56 )

Poecilaema marmoratum Roewer, 1915: 124 . Paecilaema marmoratum: Roewer, 1923: 369 , fig. 445.

Type data: Syntypes: Argentina. Buenos Aires: Bahia Blanca [–38.67581°, –62.22026°], 2 ♀ ( SMF RI, examined by photograph) .

Distribution: Only known from type locality reported by Roewer (1915), which is in Humid Pampas ecoregion in Bahia Blanca, Argentina ( Fig. 48 ). This locality is probably incorrect and maybe the material used by Roewer was sent from the ancient port of Bahia Blanca and that is why it is on the label ( Fig. 56C ), but collected somewhere else.

Remarks: Although this species was not used as a terminal in the present analysis, examination of photographs of type of this species – in an advanced stage of this project – allows us to recognize it as a member of Gryne [and not Paecilaema , as diagnosed in Kury & Medrano (2018)]. However, the photographs ( Fig. 56 ) do not allow us to detect a possible synonymy with any member of Gryne . The only species of Gryne occurring in Argentina is G. orensis . Ringuelet (1959) examined type material of both G. orensis (described by him as P. neglectum and here considered a junior synonym) and P. marmorata and did not recognize such similarity as to consider them the same species.
