Baviera, Cosimo, Bellò, Cesare & Osella, Giuseppe, 2012, First record of the genus Bordoniola Osella, 1987 in Ecuador with description of five new species (Coleoptera: Curculionidae, Raymondionyminae), Zootaxa 3455, pp. 69-80 : 78

Bordoniola simillima sp. n.

( Figs. 8, 8 A)

Type locality. Ecuador, Pichincha, Nono.

Diagnosis. Small size body (1.12 mm), elongate, light brown, shiny. Pronotum sub-cylindrical with small round punctures separated by smooth spaces. Second and third elytral intervals flat. Body with very short setae.

Type series. Holotype female (OSL) with the following labels: [transparent label with genitalia in DHMF]; "Ƥ" [white, printed]; “ Ecu, Pichincha, dint. Nono 3120 m ”, 6 VIII ‘08 “[white, printed]; “S 00° 0 5. 849'–W 78° 33. 404’, vaglio sub-paramo” [white, printed]; “ Ecuador 2008, legg. Baviera, Bellò, Osella & Pogliano” [white, printed]; "coll. Cesare Bellò" [green, printed]; " Bordoniola simillima sp. n., Holotypus, det. Osella 2011" [red, printed]; “foto Bellò 2011”[yellow, hand-written].

Holotype female: Length: 1.10 mm. Body sub-cylindrical with bright tegument (especially the rostrum), light brown, bristles sparse, very short, erect, placed mainly at the elytral sides. Rostrum wider in the second half separated from the head by a small impression, dorsally smooth, slightly curved beyond midlength, shining between the head and antennae. Antennae rather long, scape slightly thickened from base to apex, funiculus with first article about twice longer than wide and more robust than the others, articles two to six sub-spherical, seventh more robust than previous, club large (a little larger than in B. minima ), oval-oblong, bristly, length about the same as the five articles of the funiculus. Head conical, bright. Pronotum subcylindrical, longer (0.28 mm) than wide (0.22 mm), with round, small, irregularly arranged punctures. Scutellum absent. Elytra sub-oval at the sides, almost twice as long (0.56 mm) as wide (0.30 mm) with humeri absent and elytral suture visible, slightly convex dorsally, intervals two and three flat (or third interval very slightly more elevated) with round punctures on the disc, absent posteriorly. Legs robust, with enlarged profemora, serrate on the outer margin, hollow on the inside; protibia slightly serrate on the outside. Claws free. Procoxae separated at the base; sternites III–IV wide (III larger than IV), sternite VII smooth and flat. Spermatheca as in Figure 8 A.

Distribution. Known only from the type locality.

Etymology. The name “ simillima ” is related to the close similarity between this species and B. minima n. sp.

Comparative notes. This species is very close to B. minima in size, form of rostrum, pronotum with well-separated round punctures, elytral intervals two and three flat. It is distinguishable by the sub-cylindrical pronotum (medially expanded in B. minima n. sp.) with smaller punctures interspersed with smooth flat spaces (punctures slightly larger in B. minima n. sp.), and by very short indistinct bristles.

Ecology. The holotype of this species was collected by screening leaf litter in a residual limb of a primary forest
