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); 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). 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.
