description: Estoloides giesberti sp. nov.
(Figs 135–139)
Description. Female (136–139). Integument mostly black; scape, pedicel and antennomere III dark brown; antennomeres IV–X reddish brown with basal ring slightly lighter; antennomere XI reddish brown with basal and distal ring slightly lighter; femora dark brown; tibiae dark brown with dark reddish brown areas; tarsi reddish brown.
Head. Frons and vertex coarsely, moderately abundantly punctate; with grayish yellow pubescence partially obscuring integument, but distinctly exposing punctures, with short, suberect, yellowish setae interspersed, and long, erect yellowish setae close to eyes. Area behind upper eye lobes impunctate, with grayish yellow pubescence partially obscuring integument. Area behind upper eye lobes, finely, sparsely punctate on tumid area close to eye, impunctate on remaining surface; with ashy, sericeous pubescence on tumid area, with long, erect yellowish setae interspersed, glabrous on remaining surface. Antennal tubercles impunctate; with grayish yellow pubescence partially obscuring integument, interspersed with a few long, erect yellowish setae. Median groove distinct from clypeus to prothoracic margin. Genae transversely striate near eye, with a few fine punctures toward apex; with ashy, sericeous pubescence with a few long, erect yellowish setae interspersed toward ventral side. Gulamentum smooth and glabrous except on elevated anterior area with ashy, sericeous pubescence with a few long, erect yellowish setae interspersed. Labrum finely, moderately abundantly punctate; with long, erect, sparse yellowish and brownish setae, more abundant laterally. Distance between upper eye lobes 0.65 times length of scape (2.67 times width of one lobe); in frontal view, distance between lower eye lobes 0.95 times length of scape. Antennae 1.55 times elytral length, reaching elytral apex at middle of antennomere X. Scape gradually widened toward middle, without strong curvature on basal third internally; with yellowish pubescence dorsally, not obscuring integument, with ashy, sericeous pubescence ventrally; with long, erect, sparse yellowish setae dorsally and ventrally. Antennomeres with yellowish pubescence not obscuring integument, except basal ring with grayish yellow pubescence; ventral side of antennomeres III–IX with long, erect yellowish setae, gradually shorter and sparser toward IX. Antennal formula (ratio) based on length of antennomere III: scape = 0.77; pedicel = 0.16; IV = 0.98; V = 0.71; VI = 0.62; VII = 0.58; VIII = 0.50; IX = 0.46; X = 0.39; XI = 0.44.
Thorax. Prothorax, maximum width 1.4 times wider than long (including lateral tubercles); lateral tubercles large, placed at middle, with apex subacute. Pronotum with 3 low, slightly distinct gibbosities, one barely distinct, subelliptical, placed centrally on basal half, one subcircular placed on each side of distal half; coarsely, abundantly punctate, except on smooth central gibbosity and part of subcircular gibbosities; with grayish yellow pubescence partially obscuring integument, but distinctly exposing punctures, ashy laterally; with long, erect, sparse yellowish setae laterally. Sides of prothorax coarsely, moderately abundantly punctate on wide area close to pronotum (punctures finer than on pronotum), impunctate toward ventral side; with ashy, sericeous pubescence not obscuring integument. Ventral side of thorax with ashy, sericeous pubescence not obscuring integument; prosternum moderately finely punctate close to procoxal cavities, smooth on remaining surface; prosternal process longitudinally, widely sulcate centrally; coarsely rugose-punctate; mesoventral process finely, sparsely punctate. Scutellum with dense pale yellow pubescence. Elytra. Coarsely, moderately abundantly punctate throughout (punctures finer than on pronotum); with grayish yellow pubescence obscuring integument, but distinctly exposing punctures, interspersed with short, suberect, moderately abundant brownish setae; apices individually rounded. Legs. Femora with ashy, sericeous pubescence. Tibiae finely, moderately sparsely punctate; with ashy, sericeous pubescence distinctly exposing punctures, with long, erect yellow setae interspersed.
Abdomen. Ventrites finely, shallowly punctate laterally; with ashy, sericeous pubescence distinctly exposing punctures, with long, erect, yellowish setae interspersed, especially laterally, more brownish on ventrite V; distal area of ventrite V depressed; apex of ventrite V truncate.
Male (Fig. 135). Antennae longer (2.05 times elytral length, reaching elytral apex at base of antennomere IX); distal area of abdominal ventrite V not depressed; apex of ventrite V truncate.
Variation. Antennomeres dark brown, slightly, gradually lighter toward XI; basal light ring distinct only after antennomere VIII; femora almost black; tibiae entirely dark brown; tarsomeres I–II dark brown; tarsomere III dark reddish brown; tarsomere V reddish brown except dark brown distal area.
Dimensions (mm), holotype female/ paratype males. Total length, 13.23/12.28–12.42; prothoracic length, 2.70/2.58–2.61; basal prothoracic width, 3.10/2.74–2.76; distal prothoracic width, 2.70/2.34–2.45; maximum prothoracic width (between apices of lateral tubercles), 3.73/3.42–3.62; humeral width, 4.32/3.87–4.05; elytral length, 8.18/8.05–8.61.
Type material. Holotype female from HONDURAS, Islas de la Bahia: Isla Roatán, 26–30.V.1978, Giesbert col. (FSCA). Paratypes – 2 males, same data as holotype (1male FSCA, 1 male MZSP).
Etymology. Named for Edmund F. Giesbert, in recognition of his many contributions to our knowledge of New World Cerambycidae, and to his pioneering spirit, that led him to many adventurous places in the search of another new species.
Remarks. Estoloides giesberti sp. nov. is similar to E. rufipes Breuning (Figs 141–143), but differs as follows: elytra slightly shorter (about 3 times pronotal length in male, about 3.5 times in female); dorsal pubescence grayish yellow; femora from dark brown to black; elytral setae shorter (Fig. 139). In E. rufipes, the elytra are longer (about 3.5 times pronotal length in male, about 3.8 in female), dorsal pubescence ashy, femora from reddish to dark reddish, and elytral setae are longer (Fig. 143).
