Type material. Lectotype (present designation), “ Cyphon \ parvum Sol. \ Chili ” [handwritten with brown ink, prob- ably by Solier]; “9 \ 45: [handwritten on a green, round label]. The specimen is relatively well preserved but ventral portion is slightly damaged, and only anterior legs are preserved.

Description. Female, TL = 3.5 mm. Body uniformly light yellow. Punctures on elytra separated by ca. 0.5 di- ameter of a puncture. Anterolateral angles of pronotum slightly projecting anteriorly, posterolateral angles obtuse. Ovipositor with long apodemes and membranous coxites, coxites with styli; prehensor absent, only some invaginations (L 0.17 mm, W 0.13 mm) of membrane can be noticed in vagina ( Fig. 7A View FIGURE 7 ); sclerotized structure (diameter ca. 0.35 mm) present at base of accessory gland.

Remarks. The species is pollinophagous, as numerous pollen grains are preserved in intestines ( Fig. 7A View FIGURE 7 ). A similar sclerotization of basal portion of accessory gland was described in Ypsiloncyphon Klausnitzer ( Zwick 2016) and named dictyon. The original description includes no information on the number of specimens examined by Solier. 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.
