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 : 70-71

Bordoniola ecuadorialis sp. n.

( Figs.3, 3 A, 4, 4A)

Type locality. Ecuador, Pichincha, San Josè de Minas.

Diagnosis. Small body size (1.30–1.55 mm), elongate, reddish-brown, shiny. Rostrum dorsally finely punctuate, apex smooth and shiny. Pronotum with dense, round punctures. Protibia with external teeth. Elytra with second and third intervals raised above first and second striae, each with 8 to 10 round punctures, not always aligned, between the base and declivity.

Type series. Holotype male (OSL) with the following labels: [transparent label with genitalia in DHMF]; “ Ecu, Pichincha, San Josè de Minas, Cerro Blanco 3.150 m ” [white, printed]; “N 00° 12. 624’–W 78° 21. 050’, vaglio subparamo, 14 VIII ’08” [white, printed]; “ Ecuador 2008, legg. Baviera, Bellò, Osella & Pogliano” [white, printed]; "coll. Cesare Bellò" [green, printed]; " Bordoniola ecuadorialis sp. n., Holotypus, det. Osella 2011" [red, printed]; “foto Bellò 2011” [yellow, hand-written]. Paratypes: 4 males and 4 females, Ecu, Pichincha, San Josè de Minas, Cerro Blanco 3.150 m, N 00° 12’ 624’’– W 078° 21’ 050’, vaglio subparamo, 14 VIII ’08, Ecuador 2008, legg. Baviera, Bellò, Osella & Pogliano (BAV, BEL, OSL). Types are 9 (5 males and 4 females), genitalia of 4 (2 males and 2 females) were studied.

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 Figure 4 A.

Other material. A single female, labeled “Ecu, Pichincha, San Josè de Minas, Cerro Blanco 3.150 m, N 00° 12. 624’–W 78° 21. 050’, vaglio subparamo, 14 VIII ’08, Ecuador 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.

Distribution. Known only from the type locality.

Etymology. The species take its name from the nation of Ecuador.

Comparative notes. The closest species is B. otongana sp. n. from which B. ecuadorialis sp. n. differs in the characters shown in the table.

Ecology. Specimens of this species were collected screening subparamo deep litter at the base of the bushy tree line area (slope S– O).
