Micridium angulicolle ( Fairmaire, 1858) View in CoL as Ptilium angulicolle

( Figs. 1 View FIGURES 1 – 14 , 29 View FIGURES 17 – 32 )

Habitus Fig. 1 View FIGURES 1 – 14 . Length 0.52 mm. Colour: dark yellowish brown, antennae and legs yellow, elytra transluscent. Antonnomeres 3–11 length 0.19 mm. Width across eyes 0.16 mm. Pronotum length. 0.13 mm, width 0.18 mm, widest in anterior half, strongly punctured and pubescent, and without distinct linear depressions, lateral margins sinuate behind middle, Fig. 29 View FIGURES 17 – 32 . Elytra length, 0.33 mm, width 0.22 mm, sides evenly rounded, widest at middle, less strongly punctured and pubescent than the pronotum, shining. Wings visible through the elytra.

Remarks. The description, figure and measurements are based on the syntype in BMNH. This is mounted on a small piece of clear mica(?) attached to a card with the rear corners cut off. Labels are present as follows: ' angulicolle Brisout 1866 ' (in Matthews' hand, back corners also cut off); ' angulicolle Type from M. Brisout de Barneville France 1866' (in Matthews' hand on blue card with the rear corners cut off); '2239' (Matthews/Mason collection number); ' Matthews coll. 1904 - 120' ( BMNH accession number) and 'Syntype' (added by BMNH). ( Fig. 1 View FIGURES 1 – 14 ).

Details of the ventrum, viewed through the mount, were not sufficiently clear to enable positive determination to Micridium and for the reasons given above no attempt was made to detach the insect or to dissect it so that the sex is not known.
