Type material. Lectotype (present designation), “ Cyphon \ collare Sol \ Chili ” [handwritten with brown ink, prob-

ably by Solier]; “9 \ 45: [handwritten on a green, round label]. The specimen is missing legs, and its right elytron is damaged.

Description. Male, body oval, TL 3.7 mm. Head brown, pronotum orange, scutellar shield and elytra brown, elytra with slightly lighter suture, antennae, legs, and ventrum brown. Punctures on elytra separated by ca. 0.5 diameter of a puncture, punctures on pronotum slightly sparser than on elytra, separated by ca. 0.7 diameter. Anterolateral angles of pronotum widely rounded, not projecting. Penis (L 0.52 mm, W 0.19 mm) elongate, basal portion longer than parameroids, trigonium subtriangular, with rounded apex, parameroids longer than trigonium, widening toward apices, apical portion narrower, rounded; tegmen (L 0.48 mm, W 0.20 mm, styli not included) with very narrow parameres, regularly narrowing till apices, styli present; tergite VIII (L 0.37 mm, W 0.39 mm) with transversely subrectangular apical plate, apical margin covered with sparse setae, apodemes short, ca. 0.3 × length of apical plate; tergite IX (L 0.35 mm, W 0.33 mm) similar to tergite VIII but more membranous and without setation at apical margin; sternite VIII (L 0.18 mm, W 0.30 mm) v-shaped, setation indistinct; sternite IX (L 0.36 mm, W 0.23 mm) elongate, consisting of two subtriangular hemisternites, with sparse setae in apical portion.

Remarks. 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.
