Description
Female. Integument black except dark reddish brown on distal half of labrum, and narrow yellowish-brown apex of abdominal ventrites I – IV.
Head. Frons minutely, densely, shallowly punctate except nearly smooth narrow central area on each side of median groove; with yellowish-brown pubescence not obscuring integument; with a few long, erect, dark setae close to lower eye lobes. Area between antennal tubercles with sculpturing and pubescence as on frons. Remaining surface of vertex minutely, sparsely punctate; with yellowish-brown pubescence, shorter than on frons, not obscuring integument. Area behind upper eye lobes minutely, densely punctate, with yellowish-brown pubescence not obscuring integument; area behind lower eye lobes with band of yellowish-brown pubescence close to eye, glabrous on remaining surface. Antennal tubercles with sculpturing and pubescence as on frons. Median groove well marked from clypeus to prothoracic margin. Genae densely, microscopically punctate except smooth distal area; with sparse, decumbent yellowish-brown setae except glabrous distal area. Gulamentum smooth, glabrous except narrow area close to mentum with moderately sparse, short yellowish-white setae. Postclypeus nearly horizontal close to frons, abruptly inclined towards anteclypeus; area close to clypeus glabrous centrally, with yellowish-brown pubescence on each side of central area, glabrous laterally; area close to anteclypeus with yellowish-brown pubescence throughout; with a long, erect, dark, thick seta on each side of margin between horizontal and inclined areas. Labrum coplanar with anteclypeus at posterior third, inclined at remaining surface; with long, erect, thick dark setae on posterior third and laterally; with fringe of yellow setae at anterior margin. Distance between upper eye lobes 0.29 times length of scape; in frontal view, distance between lower eye lobes 0.85 times length of scape. Antennae 1.9 times elytral length, reaching elytral apex at base of antennomere VIII; scape with yellowish-brown pubescence partially obscuring integument, ventrally with sparse, erect dark setae interspersed; antennomere III with yellowish-white pubescence on basal third, gradually yellowish brown towards apex (left antennomere with small golden pubescent spots on distal half; antennomere IV with yellowish-white pubescence on basal 2/3, gradually yellowish brown on distal third; antennomeres V – XI with yellowish-white pubescence at about basal half, gradually yellowish brown towards apex; antennomeres III – VII with sparse, erect, thick dark setae ventrally (shorter and sparser towards VII); antennal formula (ratio) based on length of antennomere III: scape = 0.81; pedicel = 0.13; IV = 1.07; V = 0.69; VI = 0.59; VII = 0.56; VIII = 0.52; IX = 0.46; X = 0.44; XI = 0.47.
Thorax. Prothorax 1.65 times wider than long. Tubercles of pronotum with top obliquely inclined; central area with row of moderately fine punctures, convergent from base to apex; with yellowish-brown pubescence not obscuring integument, more conspicuous laterally, except nearly glabrous apex of tubercles. Sides of prothorax with row of coarse punctures basally and distally (following those of pronotum), not reaching prosternum; with yellowishbrown pubescence partially obscuring integument (more golden depending on angle of light source). Prosternum narrow, with yellowish-brown pubescence not obscuring integument (more golden depending on angle of light source); prosternal process with narrowest area about half width of procoxal cavity; centrally widely, distinctly depressed; with yellowish-brown pubescence not obscuring integument (more golden depending on angle of light source). Central area of mesoventrite with short, sparse yellowish-brown pubescence; remaining surface of mesoventrite, mesanepisternum, mesepimeron, metanepisternum and metaventrite with yellowish-brown pubescence partially obscuring integument (less so centrally on metaventrite). Mesoventral process centrally emarginate at apex, with short tab projected laterally under mesocoxae; surface nearly flat. Scutellum somewhat depressed centrally; with yellowish-brown pubescence not obscuring integument.
Elytra. Coarsely, moderately abundantly punctate on anterior third, gradually sparser towards apex; with large, elevated carina on centre of anterior quarter, gradually less elevated towards its apex; area between carina and anterior area on each side near humerus with golden pubescence not obscuring integument; remaining surface with yellowish-white pubescence (more greyish white or golden depending on angle of light source), interspersed with glabrous or nearly glabrous, irregular areas; apex wide, slightly sinuous.
Legs. Femora with yellowish-brown pubescence partially obscuring integument. Tibiae with yellowish-brown pubescence basally, wide central area with yellowish-white pubescence, with dark abundant, nearly decumbent, thick setae distally; with long, erect, thick, dark setae dorsally.
Abdomen. Ventrites with yellowish-brown pubescence abundant, but not obscuring integument.
Dimensions (holotype female). Total length, 9.50; prothoracic length, 1.80; posterior prothoracic width, 2.60; anterior prothoracic width, 2.20; maximum prothoracic width (between apices of lateral tubercles), 2.95; humeral width, 4.05; elytral length, 6.80.
Type material. Holotype female from BRAZIL, Espírito Santo: Linhares, November 1972, coll. P. C. Elias (MZSP).
Etymology. The specific epithet ‘Eris’ is a noun in apposition and refers to the Greek goddess of strife and discord.
