Holotype
male: Length:
1.50 mm
. Body sub-cylindrical, dark brown, elytra with sparse very prominent bristles, long, erect, placed mainly at the sides. Gently curved rostrum, sub-parallel after the middle, bright, stripedrough between head and antennae. Antennae rather long, scape gradually thickened; funicle with first article about twice longer than wide and more robust than the remaining sub- spherical articles (second to sixth), seventh slightly larger than sixth, club very large, oval-elongate, bristly, long last about the same as the five articles of the funicle. Heađ subspherical, partially cοveređ by prοnοtum, separateđ frοm rοstrum by small cοnstrictiοn• Prοnοtum subcylindrical, longer (
0.40 mm
) than wide (
0.33 mm
) with maximum width in the middle, narrowed before, with punctures separated by smooth spaces the distance between which are equal to or greater than the diameter of the same punctures. Scutellum absent. Elytra twice as long (
0.8 mm
) as wide (
0.4 mm
) with rounded humeri, suture evident, convex, intervals two and three flat and smooth, striae two and three with 9 punctures well delineated on disc, evanescent to declivity. Legs short and robust, femora enlarged, slightly hollowed on inner side, protibia slightly serrate on the outer side to form a single edge often encrusted with soil. Claws free. Procoxae separated at the base; sternites III–IV wide (III larger than IV), sternite VII smooth and flat. Aedeagus as in
Figure 3
A.
Paratypes
:
Type
series variability is minimal, only pronotum and first and second elytra strial punctures were quite different. In females, the protibia are more regularly expanded, externally toothed. Spermatheca as in

A single female, labeled “Ecu, Pichincha, San Josè de Minas, Cerro Blanco

2008, legg. Baviera, Bellò, Osella & Pogliano” (OSL) is characterized by clear red teguments (immature?), finely punctured rostrum, pronotal punctures smaller, elytral intervals two and three flat (slightly raised in other species) with elytra dorsally convex. This may prove to be a separate species that we did not describe due to the absence of more mature specimens.
