Epipoda vanini sp. nov.

Figs. 4A, 4B

Holotype: female, 8.35 mm, deposited in the MZUSP. Male not known.

Diagnosis: see under Epipoda abeli .

Description of holotype ( Figs.4A, 4B ):forebody about 1.22 longer than abdomen (estimated 3.35 mm); prothorax 1.33 wider than width of head across eyes (1.20 mm).

Colour: the following black: head (except mandibles, labrum and clypeus chestnut), prothorax (only post coxal process pale chestnut), meso- and metasterna (except sides of mesosterna pale chestnut), abdominal segments (except most of urosternite I with pale chestnut infusion, and apical tergite almost entirely pale chestnut). Mouthparts yellowish, apical palpomeres chestnut. Elytra with basal fifth pale chestnut, posteriorly black, except for translucent panels (the latter framed by black colour, except anteriorly where the frame is narrowly interrupted). Antennae entirely chestnut. Coxae, and margins of all coxal cavities partially, pale chestnut. Legs pale chestnut (the claves lacking black infusion), femoral peduncles and base of tibiae yellow (basal fifth of metatibia); tarsi almost black.

Structure: rostrum 3.00 wider than long (0.30 mm). Width of one inferior lobe of eye 2.50 interocular distance (0.2 mm). Distance between superior lobes of eyes 3.00 width of one lobe (0.15 mm). Distance between antennal tubercles 2.75 width of scape (0.20 mm). Scape short and narrow, 1.0 × 0.4 units; but antennomeres generally more crassate: middle of V much wider than apex of IV, and apex of V 5 units wide; and VII-IX 5 to nearly 6 units wide). Lengths of antennal segments: scape 0.50 mm; pedicel 0.20 mm; III 0.65 mm; IV 0.30 mm; V 0.50 mm; VI and VII 0.40 mm; VIII and IX 0.35 mm; X 0.30 mm; XI 0.40 mm. Prothorax 1.06 longer than wide (1.60 mm); prothoracic quotient 2.13; apical and basal margin equally wide (1.20 mm). Procoxal cavity 5.50 wider than base of prosternal process (0.10 mm). Mesocoxal cavity 3.67 wider than base of mesosternal process (0.15 mm). Elytra 1.72 longer than width across humeri (1.60 mm); nearly reaching apex of urosternite I. Length of mesosternum 0.90 mm, length of metasternum 1.00 mm. Abdominal segments incrementally shorter towards apex; length urosternite I 0.95 mm; II 0.75 mm; III 0.70 mm, IV 0.65 mm; V 0.45 mm (partly retracted). Urosternite IV without fossa. Ratio front/middle/ hind leg 1.0:1.2:1.9. Profemur 1.17 longer than protibia (1.15 mm); mesofemur 1.23 longer than length of mesotibia (1.30 mm); mesofemur 3.20 longer than width of clave (0.50 mm). Length of body 1.4 longer than hind leg (6.15 mm); metafemoral clave 1.78 longer than peduncle (0.90 mm); apex of metafemora reaching basal quarter of usosternite IV; metatibia 1.04 longer than metafemur (2.50 mm); metatibia 2.48 longer than metatarsus (1.05 mm); metatarsomere I about 1.13 longer than length of II + III.

Measurements (mm): holotype, total length 8.35; length of pronotum 1.70; width of pronotum 1.60; length of elytra 2.75; width at humeri 1.60.

Holotype: female, BRAZIL, Pará: Serra Norte , 11-14. VIII.1984, I.G. Fefoca col. ( MZUSP).

Etymology: this species is named in honour of my good friend, Sergio Vanin, for his contributions to the knowledge of South American Coleoptera .
