3.7 Baeocera jarmilae nov.sp. ( Figs 7-9 )

T y p e m a t e r i a l: Holotype ♂, CHILE: Malleco ; Princesa 20 km W Curacautin 12.XII.84 - 16.II.85 S & JPeck, FIT, 1000 m Nothofagus forest ( MHNG) . Paratype ♂ CHILE: Alto de Vilches , 70 km E Talca, 5.XII.84 - 20.II.85 S&J.Peck, Nothofagus forest, 1300 m ( MHNG) .

D e s c r i p t i o n: Length 1.35-1.42 mm, width 0.82-0.85 mm. Body nearly uniformly light reddish-brown or elytra slightly lighter and metaventrite darker than pronotum, apical abdominal segments yellowish, femora as pronotum, tibiae, tarsi and antennae lighter. Eye width as two thirds of shortest interval between eyes. Length/width ratios of antennomeres as: III 15/6: IV 15/6: V 21/6: VI 19/7: VII 28/8: VIII 27/8: IX 31/10: X 34/14: XI 52/15. Dorsal and ventral sides of body not microsculptured. Pronotal punctation very fine, hardly visible at 80 times magnification. Tip of scutellum hardly visible. Elytra widest posterior basal sixth, distinctly narrowed from widest point toward apices; sutural striae not shortened, starting at elytral base, extended laterad from pronotal lobe to form basal striae, reaching about mid-width of elytral base, adsutural areas flat. Elytral punctation less fine than pronotal punctation, distinct at 40 times magnification on inner part of disc, on outer part of disc with scattered larger, well visible punctures. Mesepimeres about 2.5 times as long as wide and two times as long as intervals between them and mesocoxae. Metaventrite flattened in middle part, lacking impressions, very finely punctate except on apicomedian area bearing patch of distinct punctures; punctation on lateral parts of metaventrite about as fine as on pronotum. Submesocoxal areas about 0.05 mm long, as long as third of shortest intervals between them and metacoxae; submesocoxal lines convex, distinctly punctate. Metanepisterna flat, in middle about 0.03 mm wide, nearly parallel-sided, with deep, straight slightly curved suture. Tibiae straight, thickened apically.

Male characters: Protarsomeres I-III hardly widened. Aedeagus as Figs 7-9 , 0.43- 0.45 mm long.

E t y m o l o g y: The species is named after one of its collectors, Jarmila Kukalová-Peck (Ottawa), an eminent palaeontologist and a great colleague.

C o m m e n t s: This species may be distinguished from its Chilean congeners by the light body colour, the elytra with basal striae not joined to lateral striae, the comparatively small submesocoxal areas, and the aedeagus bearing a long, strongly curved and gradually narrowed flagellum.
