( Figs. 4 View Figure A–K)

Habitus Figs. 4 View Figure A–B. Length 1.03–1.06 mm. Colour dark brown appearing paler on lateral margins and underside of pronotum, and posterior margin of the elytra; exposed abdominal segments, legs and antennae dusky yellow. Antennomeres 3–11 0.39–0.41 mm long Fig. 4 View Figure C. Mentum and submentum chaetotaxy Fig. 4 View Figure D. Width across eyes 0.38–40 mm. Pronotum 0.66–0.67 mm wide, 0.32–0.34 mm long, slightly wider than elytra at shoulders. Elytra 0.58–0.62 mm long, 0.63–0.64 mm wide, widest across the humeri and with a setae bearing epipleuron stretching to two thirds the length of the elytron and projecting from the lateral border of the mesoventrum Fig. 4 View Figure G (right side). Mesoventral collar not extending onto the humeri, mesoventral process reaching posterior margin of collar, posterior margins straight, sloping anteriorly to lateral margins Fig. 4 View Figure G. Posterior margins of metaventrum straight, sloping anteriorly to lateral margins, metacoxal plates large and rounded Fig. 4 View Figure H. Pygidium with a small central tooth and two large lateral teeth in the posterior half, longer setae as present in many species of Acrotrichis  absent, anterior border setiferous Fig. 4 View Figure J. Sixth visible ventrite with two posteriorly directed setae Figs. 4 View Figure I, K.

Male: aedeagus Fig. 4 View Figure E; ventrite VI with median excision Fig. 4 View Figure I.

Female: spermatheca with duct tapering seamlessly into the receptacle Fig. 4 View Figure F.

Etymology. The name honours the birthplace of Paddington Bear, the beloved children’s literature character created by the UK author, Michael Bond, in 1958. Paddington was an immigrant from “darkest Peru ” ( Bond 1958). He is certainly a member of Tremarctos ornatus Cuvier, 1825  ( Ursidae  : Temarctinae), the Andean spectacled bear or Andean short-faced bear (jukumari in Aymara; ukumari or ukuku in Quechua). Spectacled bears are found in the Andes Mountains, from Colombia to Bolivia and ranges down to at least 550 m at the Villa Carmen station (where footprints have been documented; installed camera traps may document them yet; A. Tejedor, pers. commun.). The bear species is listed on the IUCN Red List of Threatened Species ( Goldstein et al. 2008) and it is not known how many are left in the wild. We thus hope that drawing attention to this vulnerable flagship species will promote conservation of its fragmented habitats and for the other threatened plants and beetles including P. osopaddington 'Paddington  beetle'.

Diagnosis. Only likely to be confused with P. peruviensis  from which it differs in being narrower and in the shape of the genitalia. Additionally the gap between the metacoxae is smaller in this species.
