The penis of <i>S. permixtus</i> (Fig. 4E) is similarly ovate-lanceolate as in <i>S. badicrus</i> and <i>S. nudiventris</i> from the Atlantic region (Figs. 4C, 4D) and differs notably from those of the externally similar <i>S. lauro</i> from the Pacific region (Fig. 4F) and <i>S. scutellatus</i> from South America (Fig. 5). Female <i>S. permixtus</i> (Fig. 6E) have the distal margin of the fifth ventrite similarly strongly bisinuate as female <i>S. lauro</i> (Fig. 6F) but the two species seem to be allopatric.</p><p><b>Description.</b> Habitus short ovate (Fig. 11B), much agreeing with <i>S. lauro</i> and <i>S. scutellatus</i>; penis basally bent in lateral view, in dorsal view ovate-lanceolate with roundly narrowed apex (Fig. 4E); female with ventrite 5 transversely rugose medially and with lobe at middle of apical margin narrow (Fig. 6E); total length 2.5–3.0 mm.</p><p><b>Etymology.</b> The specific epithet is a Latin participle meaning confounded or mingled together.</p><p><b>Life history.</b> Adult weevils were collected repeatedly from <i>Catasetum maculatum</i> Kunth in Costa Rica and Panamá. Some occurred together with <i>S. badicrus</i> and an undescribed species of <i>Stethobaris</i> on <i>Gongora</i> in Costa Rica (Fig. 1). The weevil larvae that damaged <i>Gongora</i> flower buds on Barro Colorado Island (Dressler 1968) might have been either <i>S. permixtus</i> or a species of <i>Stethobaris</i>. Habitus photographs and label data provided by H. Lezama (MUCR) suggest that the observed association of <i>Stethobaris</i> sp. with <i>Vanilla</i> sp. by Rivera Coto & Corrales Moreira (2007) probably applies to a large series of <i>S. permixtus</i> gleaned from <i>V. planifolia</i> in Pococí, Limón Province, Costa Rica.</p><p><b>Distribution.</b> The species is known from the Atlantic lowland of Costa Rica and from central Panamá.</p><p><b>Material examined.</b> Holotype male, Costa Rica, labelled “COSTA Rica: Heredia / Pr: La Selva Biol.
