Type material. Lectotype (present designation), “ Cyphon \ testaceum \ Sol \ Chili ” [handwritten with brown ink, probably by Solier]; “9 \ 45: [handwritten on a green, round label]. The specimen is relatively well preserved (TL = 5.3 mm).

Remarks. Examination of prehensor ( Fig. 8 ) showed that the species is a junior synonym of Pseudomicrocara livida (Fabricius) , a very common species in temperate regions of South America. For description and illustrations of morphological features and male genitalia see Libonatti & Ruta (2003). The species was mistakenly omitted in the paper by Zwick et al. (2013). The original description includes no direct information on the number of speci- mens examined by Solier, but the note on distribution and habits suggest that Solier studied numerous specimens. A lectotype is designated in order to preserve the stability of nomenclature by selecting one specimen as the sole, name-bearing type of the taxon.
