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 : 73-75

Bordoniola relicta sp. n.

( Figs. 7, 7 A)

Type locality. Ecuador, Pichincha, Chiriboga ( Figs. 12–13 ).

Diagnosis. Small size body (1.30 mm), elongate, light brown, shiny. Pronotum and elytra with dense surface punctures. Second elytral stria impressed, pronotum and elytra slightly flattened dorsally, antenna with evident bristles at the apex of the scape, club more elongate.

Type series. Holotype female (OSL) with the following labels: [transparent label (2) with genitalia in DHMF]; "Ƥ" [white, printed]; “ Ecuador, Pichincha, Chiriboga 1600 m, 29 VII 2008 [white, printed]; vaglio bosque nublado [white, printed]; “ Ecuador 2008, legg. Baviera, Bellò, Osella & Pogliano” [white, printed]; "coll. Cesare Bellò" [green, printed]; " Bordoniola relicta sp. n., Holotypus, det. Osella 2011" [red, printed]; “foto Bellò 2011”[yellow, hand-written].

Holotype female: Length: 1.30 mm. Body sub-cylindrical with particularly bright brown tegument, some short, erect, bristles inserted mostly on the sides. Rostrum robust, bright, expanded in the second half, smooth dorsally, slightly curved distally. Antennae rather long, scape with evident bristles, gradually enlarged from base to apex, funiculus with first article about twice longer than wide and slightly more robust than the remaining articles, articles two to six sub-spherical, seventh more robust; club large (larger than in B. minima n. sp. and B. simillima n. sp.), elongate, bristly, length about the same as the last five articles of the funicle. Head conical, bright. Pronotum sub-cylindrical, longer (0.30 mm) than wide (0.26 mm), with punctures round, small, scattered, regularly arranged. Scutellum absent. Elytra sub-parallel, almost twice longer (0.66 mm) than wide (0.34 mm), with rounded humerus, elytral suture visible, dorsally slightly flattened, intervals two and three flat (or third interval slightly more elevated), with round punctures on the disc. Legs robust, profemora enlarged, apparently without serration on the outer margin, slightly hollowed on the inner margin; protibiae weakly serrate externally to form a ridge encrusted with soil, claws free. Procoxae separated at the base; sternites III–IV wide (III larger than IV), sternite VII smooth and flat.

Spermatheca as in Fig.7 .

Distribution. Known only from the type locality.

Etymology. The name “ relictus ” is derived from occurrence of the species in a residual limb of a primary "cloud" forest used as pasture for cattle.

Comparative notes. Based on the small size and the denser punctuation of the pronotum and elytra B. relictus is near B. simillima n. sp. and B. minima n. sp.. It differs in having the second stria more deeply impressed, by the brighter body, by pronotum and elytra dorsally slightly flattened (slightly convex in B. simillima n. sp. and B. minima n. sp.), by the finer and more closely spaced punctation and by the setae present on the apical part of the scape. This species also resembles B. ecuadorialis n. sp., from which it differs by the more elongate body, the fine punctation and shorter elytral bristles.

6 10 11 12 13 Ecology. The holotype of this species was collected by screening leaf litter in a residual limb of a primary "cloud" forest used as pasture for cattle on the sides of the road to Chiriboga in a small valley located on the northeast side.
