Fig. 3A E Type material. ♀ holotype , from Dantas-La Molina, Puerto Inca , 09°38’S 75°00’W , Dantas-La Molina, Huánuco , Peru , 18.V–VI.1987, leg. D. Silva ( MUSM 0504941 ) . Etymology. The specific name is a noun in apposition referring to the tall and skinny character Professor Girafales from the Mexican Television Show “Chavo del Ocho”, in reference to the characteristically long epigynal spermathecal neck. Diagnosis. The female of M. girafales is readily recognized by the conformation of the spermathecal necks, which are narrow, straight, medially fused to each other, and extremely long in relation to the secondary spermathecae ( Figs 3D, E ). Male: unknown. FIGURES 3A E.
