description: Bordoniola otongana sp. n.
(Figs. 9, 9 A)
Type locality. Ecuador, Pichincha, Otonga. (Fig. 11).
Diagnosis. Small size body (1.65 mm), elongate, red-brown, shiny. Rostrum dorsally striate-punctuate. Pronotum sub-cylindrical, narrower at the base than towards the head, punctate. Elytra sub-cylindrical with first and second striae heavily punctured, second interval more elevated than first.
Type series. Holotype female (OSL) with the following labels: [transparent label with genitalia in DHMF]; "Ƥ" [white, printed]; ” Ecuador, Cotopaxi (recte Pichincha!), Otonga, S 00° 25., W 79° 0 0., 2000 m., 1 III 2003, M. Mora ”[white, hand-written]; “Otonga, 1 3 2003, Berlese ”[white, hand-written];
" Bordoniola otongana sp. n., Holotypus, det. Osella 2011" [red, printed]; “foto Bellò 2011”[yellow, hand-written].
Holotype female: Length: 1.65 mm. Body sub-cylindrical, tegument red-shiny brown, with semi-erect long bristles sparse but evident. Rostrum sub-parallel (to the insertion of the antenna), then expanded, slightly ridged (between head and scrobe), gently curved apically. Antennae rather long, with sinuous, slightly thickened, quite slender scape; funicle with first article more than two times longer than wide and more robust than the remaining third to sixth articles sub-spherical, seventh slightly larger than the preceding; club large, oval-oblong, bristly, long, last about the same as the five articles of the funicle. Head sub-conical, smooth, separated from rostrum by a small constriction. Pronotum sub-cylindrical, longer (0.40 mm) than wide (0.32 mm), with maximum width in posterior third, very narrow, with slight narrowing anteriorly, with punctures of irregular size, separated by smooth spaces smaller than the diameter of punctures. Scutellum absent. Elytra nearly twice as long (0.84 mm) than wide (0.44 mm), sub-cylindrical, with humeri absent and visible elytral suture convex, intervals two and three slightly more elevated than other striae, with 10 to 12 evident punctures between the base and declivity, with lateral bristles raised.
Legs with femora enlarged, slightly hollowed on the inside, protibia slightly hollowed on the inside just expanded on the outside and slightly serrated to form a ridge encrusted with soil. Claws free. Procoxae separated at base; sternites III–IV wide (III larger than IV), sternite VII smooth and flat.
Spermatheca as in Figure 9 A.
Distribution. Known only from the type locality.
Etymology. The name is based on Otonga, type locality of this species.
Comparative notes. With the rostrum striate-punctuate at the base and the punctuation of the pronotum, B. otongana n. sp. is close to B. ecuadorialis n. sp. from which it differs by: the slightly larger size (1.65 mm against 1.50 mm), the elytra appreciably more elongate-cylindrical (medially more expanded in B. ecuadorialis n. sp.), the first antennal article longer, the second article as long as wide (slightly transverse in B. ecuadorialis n. sp.), the denser punctures of the pronotum, first and second striae with stronger punctures (first interval with 8–10 punctures well marked on the elytra disc and 4 more superficial posteriorly, second interval with 11–12 punctures discernible, 1–2 effaced posteriorly), remaining striae with punctures reduced but still evident on the disc; elytral bristles, long, recumbent at 60°.
Ecology. The holotype of this species was collected by screening litter in a residual limb of a primary "cloud" forest at Otonga (at approximately 2000 m elevation) during the rainy season. Repeated, subsequent sampling carried out in the same area in July–August (2002, 2004, 2006) with the traditional methods of investigation (without Winkler or Berlese extractors) were unsuccessful.
