Atrypanius jauffreti sp. nov.

Description: Holotype male: Head mostly dark brown; gulamentum dark reddish brown; scape mostly testaceous, with posterior half of dorsal surface and posterior quarter brown; pedicel testaceous except brown apical area; antennomeres III-VI yellowish brown except dark brown apex; antennomeres VII-VIII dark yellowish brown except dark brown apex; antennomeres IX-XI brown. Scutellum distinctly darker than elytra. Prothorax and elytra dark brown, except reddish brown anterior margin and posterior eight of pronotum. Mesoventrite dark brown anteriorly, orangish brown close to mesocoxal cavities; mesoventral process mostly orangish brown; mesanepisternum, mesepimeron, and metanepisternum dark brown; metaventrite mostly orangish brown except large dark brown macula on center of posterior 3/4. Legs mostly brown; metafemora dark reddish brown on peduncle,brownish on remaining surface. Abdominal ventrites mostly orangish brown.

Head: Frons slightly convex, minutely, densely punctate; with pale yellowish-brown pubescence partially obscuring integument, yellower close to eyes and pale yellow centrally (pale yellow pubescence appearing whiter depending on the intensity of the light); with one somewhat long, arched black seta on each side close to inferi- or margin of eyes. Area between antennal tubercles with pale yellow pubescence obscuring integument centrally, pale yellowish brown, partially obscuring integument laterally, except glabrous median groove and transverse sulcus between antennal tubercles and upper eye lobes; transverse sulcus and median groove forming a cross; remaining surface of vertex with pale yellow pubescence obscuring integument, except glabrous median groove. Area behind eyes with pale yellowish-brown pubescence obscuring integument. Genae 0.55 times length of low- er eye lobes; with pale yellowish-brown pubescence not obscuring integument, except dense narrow band close to eye. Wide central area of postclypeus with bristly pale yellowish-brown pubescence not obscuring integument, with one long, erect, black seta on each side. Labrum slightly convex, coplanar with anteclypeus at posterior 3/4, inclined at anterior quarter; with minute yellowish-white pubescence not obscuring integument on coplanar area, and long, erect, sparse black setae directed forward interspersed; anterior margin with short fringe of golden setae. Gulamentum smooth, glabrous, except narrow anterior area depressed, with pale yellowish-brown pubescence not obscuring integument, and a few erect dark setae near anterior margin. Distance between upper eye lobes 0.17 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes superiorly 0.48 times distance between outer margins of eyes (0.56 times inferiorly). Antennae 3.1 times elytral length, reaching elytral apex at posterior quarter of antennomere V; with yellowish-white pubescence not obscuring integument; ventral apex of pedicel with short, thick black setae; antennomeres with short, erect, sparse black setae, slightly more conspicuous apically on III-X, and short, erect, sparse white setae throughout. Antennal formula based on length of antennomere III: scape = 0.91;pedicel = 0.13;IV = 0.93;V = 0.78; VI = 0.71;VII = 0.70;VIII = 0.71;IX = 0.70;X = 0.65;XI = 0.60.

Thorax: Prothorax distinctly transverse; sides slightly rounded, gradually divergent from anterolateral angles to lateral tubercle, then abruptly narrowed; lateral tubercles somewhat large, with its apex acute, slightly directed backward, placed near posterolateral angles. Pronotum finely, abundantly punctate except posteri- or eight with sparser punctures; area near anterior and posterior margins with row of coarse punctures (slightly coarser, not surpassing lateral tubercles posteriorly); with abundant pale yellowish-brown pubescence not obscuring integument, except two pale yellow pubescent bands (appearing whiter depending on the intensity of the light) on each side of middle (subfused after middle), and pubescence of same color laterally; with a few long, erect black setae behind lateral tubercles of prothorax. Sides of prothorax minutely, densely punctate; with pale yellowish-brown pubescence partially obscuring integument. Ventral surface of thorax with abundant pale yellowish-brown pubescence not obscuring integument, denser laterally. Narrowest area of prosternal process 0.09 times procoxal width; narrowest area of mesoventral process 0.42 times mesocoxal width. Scutellum with brownish pubescence not obscuring integument. Elytra: Basal and apical thirds with abundant pale yellowish-brown pubescence (appearing more yellowish-white depending on light intensity) with irregular areas with slightly conspicuous brownish pubescence interspersed; anterior third with white pubescent macula on each side of scutellum; posterior half with abundant white pubescent macula interspersed; central third mostly with slightly conspicuous brownish pubescence, with irregular pale yellowish-brown pubescent macula interspersed; area close to suture on central third with dense white pubescent macula (together on both elytra forming subcircular macula); apex obliquely truncate. Legs: With abundant yellowish-white pubescence not obscuring integument (appearing whiter depending on light intensity), except ventral surface of tibiae with yellowish-brown pubescence (basal half of protibiae, apical third on meso- and metatibiae), and dorsal sulcus of mesotibiae with dark brown pubescence; ventral surface of meso- and metatibiae with long, oblique black setae interspersed, more abundant on metatibiae; dorsal and lateral surfaces of meso- and metatibiae with short, sparse, thick black setae interspersed, distinctly more abundant on metatibiae; tarsomeres I-III with long dark setae laterally.

Abdomen: Ventrites with abundant yellowish-white pubescence not obscuring integument; apical area of ventrite V with long black setae directed backward.

Variation: Pale yellow pubescence on pronotum forming 8-shaped macula on each side of middle.

Dimensions (mm) (Holotype / paratypes): Total length, 4.95/4.75-6.20; prothoracic length, 1.05/1.00-1.30; anterior prothoracic width, 1.30/1.20-1.60; posterior prothoracic width, 1.35/1.25-1.70; maximum prothoracic width, 1.70/1.60-2.05; humeral width, 1.90/1.85-2.35; elytral length, 3.30/3.05-4.20.

Type material: Holotype male from BRAZIL, Pará: Ulianópolis, Fazenda São Lucas , 01.I.2002, Jauffret leg. ( MZSP) . Paratypes – 1 ♂, same data as holotype except for 31.XII.2001, ex larva from Ficus sp. ( MZSP) ; 1 ♂, same data as holotype except for 06.I.2002 ( MZSP) ; 1 ♂, same data as holotype except for 08.I.2002, ex larva from Ficus sp. ( MZSP) .

Etymology: The new species is named in honor of the late Pierre Edward Jauffret.

Remarks: Atrypanius jauffreti sp. nov. is similar to A. irrorellus Bates, 1885 , but differs especially by the elytral pubescent pattern formed by two areas with dense pubescence, and with distinct white central pubescent macula (with irregular small pubescent spots and without white pubescent macula in A. irrorellus ). The other species of the genus cannot be confused with the new species, either by the pattern of pubescence distribution and/or general body shape.
