This placement was made in his dissertation and was never formally published. We believe that this species belongs in the  M. bicolorgroup despite the unusual bulbous shape of its spermathecae ( Fig. 397), more similar to those of  Souzalopesiella facialis. 2351005560 [419,604,777,802] USNM de Turrialba Costa Rica Costa Rica 123 124 1 holotype 2351005582 USNM La Suiza & de Turrialba & Pablo Schild & Ald. & AL Melander & Collection & Type & No. & W.N.
