Type material. Lectotype (present designation), female, “ Cyphon \ maculicorne \ Sol. Chili ” [handwritten with brown ink, probably by Solier]; “9 \ 45: [handwritten on a green, round label]. The specimen is relatively well pre- served (TL = 4.2 mm).

Remarks. According to the structure of the female genitalia ( Fig. 6 ) C. maculicornis is a junior synonym of Pseudomicrocara patagonica (Curtis) . For descriptions and illustrations of morphological characters, including male genitalia, see Libonatti & Ruta (2013). It is clear that Solier studied more than a single specimen of this species as ranges of measurements were noted in the original description ( Solier 1849), therefore 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.
