Mimogonia duckei   sp. nov.

( Figs 3 View Figs 1–3. 1 , 16C View Fig )

Type locality. Brazil, Estado Amazonas , Manaus   .

Type material. HOLOTYPE:, ‘ Brazil, Amazonas , Reserva Ducke, 26 km NE of Manaus, flight intercept trap, 1995–1996, # 2003-84 ( BMNH)   . PARATYPES: 2♀♀, with same data as holotype ( BMNH)   .

Diagnosis. This species can be identified by the large coarse setiferous punctation of the fore-body and the extremely wide elytra. According to the large prominent eyes, and a head/ pronotum width ratio of 0.94, it resembles M. adisi Irmler, 2007a   and M. paraensis Irmler, 2010   . However, the elytra of M. adisi   are longer than wide and in M. paraensis   they are quadrate, whereas they are distinctly wider than long in M. duckei   sp. nov.

Description. Length: 2.4 mm. Colouration dark brown; legs and antennae light brown.

Head 0.19 mm long, 0.46 mm wide; eyes large and distinctly prominent; temples extremely short; shape of fore-head semi-circular; setiferous punctation coarse and dense; interstices less than half as wide as diameter of punctures; moderately wide midline impunctate; close to neck between setiferous punctation with additional micro-punctation; remains of weak isodiametric microsculpture; surface moderately shiny.

Antennae longer than head and pronotum combined; second antennomere oval; as long as conical third; following antennomeres slightly increasing in width; fourth antennomere quadrate; tenth only slightly wider than long.

Pronotum 0.37 mm long, 0.49 mm wide; widest shortly behind middle; slightly narrowed in smooth curve to anterior obtuse angles; setiferous punctation coarse, partly coriaceous; punctures still larger than on head; on average, interstices between punctures one fourth as wide as diameter of punctures; remains of weak irregular microsculpture; wide midline without punctures and microsculpture except closely behind anterior edge; surface moderately shiny.

Elytra 0.58 mm long, 0.63 mm wide; coriaceously and densely punctate; on average, interstices between setiferous punctures less than half of diameter of punctures; remains of weak irregular microsculpture; surface moderately shiny.

Abdomen densely punctate, but setiferous punctures much finer than on fore-body; isodiametric microsculpture distinct.

Mesotibia of male with row of spines at apical outer edge; in apical third, inner edge transversely narrowed to apex and with several long and undulate setae.

Aedeagus with short hook-like curved apical lobe; apical lobe laterally with striate structure; endophallus thin, but coiled many times.

Etymology. This species is named in honour of the famous Brazilian Naturalist Adolpho Ducke, whose name was adopted as the name of the location (i.e. Reserva Ducke) where this new species was collected.

Distribution. Known only from the type locality
