description: Estoloides vandenberghei sp. nov. (Figs 64–67)
Description. Male. Integument mostly dark brown, almost black; mouthparts dark reddish brown except yellowish brown palpi; antennomeres V–X dark reddish brown on base (this area gradually wider toward X); tarsi brown, gradually lighter toward tarsomere V except claws brown.
Head. Frons moderately finely, abundantly punctate; with yellowish brown pubescence nearly obscuring integument, interspersed with long, erect brown and yellowish brown setae laterally, and moderately short, erect and curved setae centrally, more abundant along median groove near clypeus. Vertex with sculpture and pubescence as on frons (punctures sparser, absent centrally), interspersed with long, erect pale yellow setae. Area behind upper eye lobes with yellowish brown pubescence nearly obscuring integument, lighter on narrow band close to eye. Area behind lower eye lobes tumid close to eye, with transverse band with dense, minute punctures close to tumid area, with slightly coarser but sparser punctures toward prothorax; with pale yellow pubescence on tumid area, remaining surface glabrous; with some long, erect yellowish white setae on tumid area. Antennal tubercles minutely, densely punctate; with yellowish brown pubescence not obscuring integument, interspersed with long, erect pale yellow setae. Median groove distinct from clypeus to prothoracic margin. Genae finely, transversely striate (less so toward dorsal side) except smooth area close to apex; with pale yellow pubescence close to eye, more yellowish brown and sparser toward glabrous apex. Gulamentum smooth, glabrous toward prothorax; area close to mentum finely transversely striate-punctate, with yellowish white pubescence not obscuring integument, with some long, erect pale yellow setae interspersed; transversely striate, glabrous close to pubescent area. Distance between upper eye lobes 0.55 times length of scape (0.40 times width of one lobe); in frontal view, distance between lower eye lobes 0.85 times length of scape. Antennae 1.9 times elytral length, reaching elytral apex at about distal quarter of antennomere VII (missing antennomere XI of left antenna and antennomeres VIII–XI of right antenna); scape and pedicel with long, erect yellowish white setae throughout; antennomeres III–VII with long, erect yellowish white setae ventrally, gradually shorter, sparser toward VII; base of antennomeres III–X with yellowish white ring of pubescence (gradually wider toward X); antennal formula (ratio) based on length of antennomere III: scape = 0.65; pedicel = 0.13; IV = 1.03; V = 0.80; VI = 0.74; VII = 0.72; VIII = 0.65; IX = 0.64; X = 0.57.
Thorax. Prothorax, maximum width, 1.25 times wider than long (including lateral tubercles); lateral tubercles small, placed slightly before middle, with apex acute. Pronotum with five low gibbosities, one elongate, wide, from basal transverse sulcus to distal margin (distinctly narrowed from at about middle to distal margin), one large, subcircular at each side of distal half, two less distinct, subcircular at each side of basal half; coarsely, moderately sparsely punctate (denser laterally between base and lateral tubercles), except on smooth central and laterodistal gibbosities; with yellowish brown pubescence partially obscuring integument, with long, erect yellowish white setae interspersed. Sides of prothorax striate on base, coarsely, moderately sparsely punctate on wide central area, nearly smooth on wide, oblique area from procoxal cavity to distal margin; with yellowish brown pubescence, not obscuring integument, on sculptured area, yellowish white, sparser on nearly smooth area; with long, erect, sparse yellowish white setae except on nearly smooth area. Prosternum finely, sparsely punctate; with yellowish white pubescence not obscuring integument, interspersed with long, erect, yellowish white setae. Prosternal process slightly coarsely, sparsely punctate on base, widely sulcate, slightly rugose on remaining surface; with yellowish white pubescence not obscuring integument, with slightly long yellowish setae interspersed (more abundant near apex). Mesoventrite and metaventrite with yellowish white pubescence not obscuring integument, with long, erect yellowish white setae interspersed on metaventrite. Mesanepisternum, mesepimeron and metanepisternum with pale yellow pubescence partially obscuring integument. Scutellum with dense yellowish white pubescence except nearly glabrous longitudinal central area. Elytra. Coarsely, moderately abundantly punctate, denser on basal half laterally; with dense yellowish brown pubescence obscuring integument, irregular areas with darker pubescence interspersed, not obscuring integument (especially on wide central region); with long erect, sparse yellowish white setae throughout; apex rounded. Legs. Femora with yellowish white pubescence not obscuring integument, with long, erect, sparse yellowish white setae interspersed.
Abdomen. Ventrites with yellowish white pubescence not obscuring integument, slightly denser and bristly laterally, with long, erect yellowish white setae interspersed, more abundant laterally. Apex of ventrite V truncate.
Dimensions (mm). Total length, 11.15; prothoracic length, 2.10; basal prothoracic width, 2.10; distal prothoracic width, 1.94; maximum prothoracic width (between apices of lateral tubercles), 2.63; humeral width, 3.15; elytral length, 7.78.
Type material. Holotype male from NICARAGUA, Nueva Segovia: Cerro Jesus (13º58’N / 86º10’W; 1,300 m), 14.V.2016, E. van den Berghe col. (FSCA).
Etymology. Named for Eric van den Berghe, who continues to find new cerambycidae species at Cerro Jesus, including this one.
Remarks. Estoloides vandenberghei sp. nov. differs from the other species of the genus by the pattern of the elytral pubescence. The general appearance resembles that of some species of Ischnolea Thomson, 1861, but differs notably by the absence of a furrow on ventral surface of metafemora (present in males of Ischnolea).
